Grass will grow even at night if you have enough light through the day (hint, doesn't require direct sunlight but can be overcast). And through a rainy week (full overcast every day) the grass will keep growing. And after a week you need to maw your lawn so your vehicle might be empty.

Not really actually. The solar panels won't serve any use after the batteries are charged. Solar panels are more efficient (and thus more commercially viable) if faced south, not in this setup. It's commercially more viable to use solar panels to feed the grid and charge your mower of the grid. It's a novel idea, but there are more efficient ways to use limited resources.
@@patrickd9551 Disagree. If you already have a grid-connected setup and a charging spot with power this may be true, but Colin's setup is completely free-standing and requires no additional setup once constructed. It can be placed basically anywhere without worrying about how you're going to get power to it. In my specific case, running power to a shed would require a permanent structure with permits pulled, and that requires a 10ft distance to any property line, which is very restricting in a smaller yard. This thing wouldn't count as a permanent structure and requires no external power, so I could back it right up to the fence line and not have to worry about it.
Yeah I like it as a self contained unit as well. Mower, Doghouse, solar setup. I understand what @Patrick D is saying, but @Drenlin hits th nail on the head with the off grid aspect of it. maybe pack the mower with batteries, and electrical outlets. then we have a decentralized, portable power station with a solar carport.
@@patrickd9551 OK, the actual shed bit's not really necessary. You could just have a standing panel, but for a low-draw application that's only used once a week, a PV panel is actually a really smart solution, if you've got the space and the right aspect on your property. Putting solar panels on EVs is a dumb marketing gimmick, but this is actually a really good idea.
I electrified my LM years ago by installing a tall pole in the middle of my yard with a 90 degrees, rotating extension which has a cable on it, which goes to the lawn mower. Haven't looked back since, 220v motor off an energy efficient (at the time) washing machine. Has the original brains modified to act as a speed controller. The programmer is stuck in the spin cycle where i can affect the speed at any time, thus giving me anything from crawl to zip, through a gearbox. It's quiet, actually cheaper than running the equivalent petrol variant (which i do once in a blue moon when power is out for whatever reason) and it's clean. Zero maintenance in 7 years other than oiling the bearings.
That is pretty cool. I have a big enough lawn that this mower would be ideal except for the fact that my mower is paid for and investing in a conversion kit will defeat the the cost of building a new or buying a new mower. There is a 48v Ryobi zero turn mower and they cost 5k. Even if I spend 1k to convert my existing mower to batteries It would take more than 10 years of buying gas to fuel it. Now I will keep my eye open for a broken one that I can pick up for next to nothing and maybe work something out with it. I might even look for some of the cordless push mowers. I am sure they break from time to time and people just buy new ones. That might be an option for parts or something. Might even be able to make a deck with the push mowers and use some sort of mobility scooter for the drive section.
I have a round lawn, a normal mower, a plug to a drum in the middle of the lawn, I tape the handle shut and put the whole thing on a timer so it stops when it gets to the middle. (in my dreams)
@@anonimushbosh They do have robot mowers that are fairly cheap around 1k. Provided you have a set up lawn they are easy to use and install. Before I bought my new house I had a yard that was going to buy one of those mowers and put it in there. Depending on the one you get you can set it up in a number of ways, I was going to add some 2x6 boards to block out some things and raise up those areas this way it makes it super easy for the robot to mow stuff. My place now is just too large I have 3 acres to maintain which I do that about every 2 weeks. Though my area around the house is getting weed barrier and stone put in. I do not need grass close to my house and this also lets me let the other grass grow wild. I am also replacing normal grass with short buffalo grass. Which if left un cut is still short and looks fine. I have a few sections growing in the yards now and going to get more seed next year and plant more as well as tranplanting plugs.
If the charging station produces more power than the mower expends in an average day, then how about taking the Subnautica approach and making the power cells easily removable; you could have a bank of spare cells charging in the shed whilst a couple permanent cells top up overnight. You could then even use the rechargeable cells in other projects too.
Improvements I would add is some kind of gauge that tells you the battery capacity and how much longer you have until the batteries die on the machine itself
@@mickys8065 Two 12v 100ah LifePO4 batteries would have replaced those 8 lead acid batteries and cost less and given him a longer run time... plus a huge weight savings...
*Electric motor Believe it or not engine and motor do have different meanings even if they are mostly used interchangeably. Shoot I read that wrong Sorry about that
Oh man the longevity of that mover is actually really impressive. The next step of course is to automate it so it cuts your grass for you like a roomba for your yard. Amazing work!
I am genuinely impressed with this project, I was a grass machinery engineer for over twenty years, retired now. Back in the 80s I had a design for a smaller robotic mower that worked on similar principals but never got round to developing it, this ride on with a decent lithium battery pack ought to change the commercial grass cutting industry.
Oh definitely and I'm sure that it wouldn't be too difficult to have this charge from the car inbetween jobs so the battery can last a full day of work and even if this were to be charged from non renewable energy it would still be more efficient than petrol (the reason is that despite the energy density of petrol the engines are incredibly inefficient due to their size and method of generation (cars are typically 30-35% with lawnmower engines being very much less so) where as coal powerstations are more efficient use to their size and method of energy conversion (40 to 45% and thats presuming 100% coal which is super rare)
This is a genuinely good idea Colin! Not only that, but your version smells a lot better (everyone can always smell when people are doing yard work with gas machinery, the exhaust fumes smell terrible), and because it's quieter, that means neighbors and such won't be disturbed by the loud sound. This is a genuine improvement. You should sell these. People would genuinely buy them.
That is all well and good for those of us who have a "lawn tractor" BUT there are differences between a "garden tractor" and a "lawn tractor" here in the States!! A Garden Tractor in fact looks like a lawn tractor but they are very different animals indeed!! You see a Garden Tractor, has attachments like snowblowers, plows, tiller options and other add ons allowing you to do way more than just "mow the lawn" and before I forget YES you can get a lawn mower for a garden tractor as well too!! My point is I used to own a Garden Tractor.....and it was always working on some project I had!! I might drag my car around the yard with it, when my car was broke down!! OR I would hook a wagon to it, while doing work in my garden or removing or planting a tree!! And sure I would even mow the lawn with my garden tractor weekly when I owned my property..........but it hardly if ever just "sat around" for a week doing nothing at all between mowing that is!!
Wow, a riding mower looks almost strange without the branding labels. - This is an amazing build, and commercially viable, particularly if sold with the charging shed!
branding was still on the steering wheel ;p I knew what it was the first frame though, since my company sells them. They do also make electric lawn mowers in the same form.
It probably took every ounce of self-control he had in him to NOT add a homemade jet engine and rocket boosters to it. Can't blame him, if given the option, most people would add those things.
Well, if he wants to make it a hybrid, he could always find a micro turbine with a PTO to turn an alternator or generator to make electricity to power it.
We generally need more electric-everything. Surprised it took this long to conceptualize an electric mower. Just goes to show you don't need to be a scientist or business magnate to create something innovative.
Loved seeing this channel just spiral in size the past year. No bragging no attention seeking. All just homely dad banter. With a genuinely nice guy. Refreshing to see
Wait a minute, this isn't nearly as life-threatening as it could be. Almost forgot what channel I was watching. But seriously, I was thinking you probably needed more power for the drive motor than the blade motor. It's pulling a lot more torque, unless you are off cutting in the bush somewhere. Anyway, magnificent job!
The only things I would add to the oackage was an inverter and outlet on the mower to run a weed eater, hedge trimmer, or electric chainsaw. A proper park/yard maintenance tool. Add a outlet to the shed as well to be able to put the excess power produced by the panels to use after the batteries are charged. The premium package. A very impressive build. So quiet. A Solar Stealth Mowar.
This is genuinely genius. Smart packaging (a sturdy wooden crate) could be repurposed as the shed/docking station, meaning nothing is wasted, you just take the solar panels out, fix them together as the roof, all already wired up just plug and play.
wonderful tech demo! would love to see this scaled up. This perfectly shows how the logistics of solar tractors work, could be done with larger farm equip. imagine the torque!
Farm equipment generally gets run 16+ hours a day during harvest. I don't think batteries are up for that yet. Batter powered lawn mower are far more logical.
@@crissd8283 Large farm equipment could be designed with swappable batterie systems then farmers could have a number of solar arrays/battery charging and swap stations strategically placed over their land. A company called John Deere have an electric tractor that runs for 4.5 hours on one charge, something like that with swappable batteries would do the trick. They also have autonomous and semi-autonomus versions so the whole swapping process could be completed automated.
Sorry, won't work (for now). A large farm would need so much power you would need a whole yard of batteries. Imagine for a 500acres farm I chew easyly during harvest (2 harvester, 3 tractors for transport, 1 loader, 1 to prepare the field) 1200l diesel/day. Preparing the soil with 2 large tractors also uses the same quantity.
This has got to be one of the most sensible ideas you have ever come up with. Not only have you created a Eco friendly Mowar it even reduces noise pollution with a cool charging station. 👍🏻 could not find any green fingers.
You really shine when you highlight the intricacies and attention to detail of your fabrication. It would be nice to see you get back to your roots a little bit in that way. IMHO.
Great idea! I would change one thing. The roof on the shed I would make a monoslope style roof, sloped in the direction and angle that's best for solar power in your part of the world.
A very practical use for solar. Bravo! But I have two suggestions. First, can you put gauges on the console so the user would know the state of charge all the time? Second, assuming you are out mowing and have finished but are far away from the charging shed, putting a switch that would shuttle the remaining charge in the front batteries to the read drive would ensure being able to get back home. Anyway, good job!
Been waiting for someone to sell a conversion kit to do this! Ryobi, and other major companies already selling them. Colin mean green mowers here in the US has lithium powered commercial grade electric mowers, with solar roof options!
@@Kenjh71 yep. We sell 'em. Advertised as "up to three acres." I'll bet there are a lot of caveats in that claim, but even if it's twice as optimistic as reality, it's impressive as heck. At us$5k per, we sold every one that came in within days. Landscapers love them... They can start cutting lawns as soon as it's light enough to see, without disturbing anyone. Puts two or even three hours onto their daily schedule - that's a lot of extra income.
Electric lawnmowers are freaking awesome. I have an 80v push mower, the battery lasts 45 minutes. With two batteries, I can easily mow my entire lawn in around an hour and half, which is the same speed as non-electric. And my batteries also work for my weedwacker, leaf blower, and hedge trimmer! They're awesome!!!
@@jerri0401 fair, I more meant the entire setup of a solar charge station and electric ride-on mower, for large areas of grass. The solar aspect especially, will charge better in summer, when grass grows more, when you don't need it as much, don't worry, it's charging a lot slower anyway... and you don't need it everyday in case of a few cloudy days...
@@N0N0111 Why would he? Why would anyone go through the trouble of digging a bunker that's better than most normal above ground house extensions, digging a tunnel system connecting the house and shed and bunker all together, a retractable roof over the area next to the house... only to go live in a boring tunnelless, bunkerless villa?
This is actually one of the most genius realistic things you've done. Have solar panels on top of your lawn equipment shed to charge all your battery powered stuff. It takes nothing from the grid, doesn't require running any power from the house. Start-up costs might be a bit higher than the average home owner may be willing to invest in. But this would be a prime opportunity for a company to offer a professional install/DIY assembly solar shed kit with financing and can also include a range of powered lawn equipment.
This could be a great application for used ev batteries. Even after beeing "not useful anymore" in cars they can be used probably up to 10 more years in these kind of projects.
as always ...lol... great idea. ...but maybe make it work with the snowblower attachment, and the rear rotor tiller, they just hook up with belts. and EV tiller...that would be cool to see. looking forward to the next video.
How about a lawnmower that runs on the grass it cuts itself? For example with a methane biodigester and a combustion engine. Although now that I think about it, that's how a goat works, which is also suitable for mowing the lawn and fertilising it.
@@classicambo9781 but the grass would have absorbed the carbon content in order to grow, so emissions wise its totally neutral - IF (and its a big if) it doesn't need any fuel besides the grass its cutting.
This is why I love his videos. Collins prediction: work for 20 mins, a week or two to charge Reality: works well over an hour, takes about two days to charge. Really good vid, keep em coming
I put a solar battery charger on my car today. It's total size is lucky to be 48x18cm and has 72 4x1.5cm cells in a 18x4 array, has a float voltage of just under 18v and can charge a battery at half an amp it has massively exceeded my expectations to say the least. I was expecting it to charge a fully flat battery in 4 or 5 days. In reality it probably will be charged by tomorrow afternoon. I guess that goes to show that solar has far greater capabilities than it is given credit for.
Colin, I love your videos - But I would love to see a much more "technical" version of them, like how did you wire the batteries? What power inverters are you using for the panels, how do you design your cnc bits - and what program are you using? I'd actually pay for something like that. You're absolutely brilliant, and I'd love to learn from you anyway I can.
Agreed! This seems like a really cool projects and I have a riding lawn mower that would probably actually make sense to do this to. Maybe he will pit something on his website?
I definitely hope that a battery company gets in touch. I'd love to see what difference that makes after seeing how effective lithium batteries were in the world's fastest ice cream van
Lots of surplus energy through those panels when sunny. Make sense to have a battery operated hot tub next door to the shed. Hot and sweaty after loads of mowing, have a chill in the hot tub after.
This is cool and all Colin but cub cadet, same company that makes the one you brought in at the beginning, already makes that exact mower in an electric model. All you really had to do was build a solar charge station for one of those lol.
Exactly what I was thinking. There are several companies now that are making electric mowers both riding and push. Though still that doesn't take away from the fact he completely swapped one over and did all the engineering and everything.
yeah, and I think they have lithium iron phosphate batteries. Dam expencive though. Prefer the ryobi zeroturn electric mower because it uses 40v battery packs that can be used in other ryobi power equipment.
Well his version using lead acid batteries just proves electric has been viable MUCH longer than lithium batteries have been around! Lead Acid batteries, when built properly (not the modern crap you get) and maintained, can last thousands of cycles and are already one of the most recycled products in industry. They are a bit heavy for vehicle use, but they would be almost perfect for a cheap grid scale energy storage. They are so simple and cheap compared to lithium for how much energy they store and how robust they are.
I'm shocked. He's actually made something that's a) completely sensible and b) a much better idea than what already exists. Also possibly c) commercially viable. You feeling alright Colin?
a) ignoring the fact that it's way too big for his garden, I agree b) this alreads exists, but smarter. There are lawn mower robots that have a solar charging station, the difference being they don't have to carry a 80kg human driver, thus can reduce the motor and batteries massively. c) taking b) into account, this could be a tough product to sell. These would basically only sell to those people who _like_ to mow their lawn manually.
@@ben_1 Robot mowers, at least the ones available right now, are not suitable for every situation. In some cases you don't want to have them around for liability reasons, and since they're much slower at getting the job done (due to literally driving slow and due to pathing inefficiencies) you also don't want them in heavily used areas, since you don't want the mower around when people are actually using the space.
Honestly speaking, you could use the other panels to give power to other things in your home. Like charge up a battery bank and have your tools pull from them before pulling from the power grid
Lead-acid batteries can only run down to 50% of their capacity, every time the charge goes lower than that you compromise their internal stability and ultimately their life. I'd suggest to have a monitor on the dash so you can tell when that's the case.
The speed controllers he is using also have an option to disable the motor when the battery voltage under load goes to low at a level that can be programed in and some of these controllers also support reserve and a host of canbus options for reading the controller data and adding instrumentation for the driver.
He should add LiFePO4 prismatic cells in this thing. Extremely cheap nowadays, it will have 3 times the energy density of lead acid and have thousands of cycles even when doing an 80% to 90% depth of discharge.
That's certainly true for a typical car battery, which is designed to provide short but intense bursts of power for the starter motors on car engines. Batteries designed this way have a large number of very thin electrode plates inside, which gives the maximum possible current, which can be several hundred or maybe even 1000 amps depending on the physical size of the battery. But of course because of this design, deep discharge can build up so much lead sulfate on the plates that they can touch each other or get bent out of shape. Then you've got a shorted cell which makes the whole battery useless, leaving it worth perhaps £5 to a scrap metal dealer but not much more. However, you can get deep-cycle sealed lead-acid batteries which are specifically designed to be discharged up to 90% or sometimes more. The battery chemistry is the same, but the internal construction is not: A deep cycle battery has a smaller number of much larger electrode plates, with enough space between them to allow plenty of lead sulfate to build up without damaging the cells. The sulfuric acid electrolyte is also usually immobilised in a sealed battery, either by gelling it with silica flour (aka fumed silica) or by absorbing it with woven glass fibre matting. This allows the battery to be mounted sideways or even upside down if you like, but the glass fibre matting helps to keep the cells rigid, stops them bending and prevents sulfate crystals growing across the gaps between electrodes. These are far more reliable and tolerate repeated deep discharge, the only downside being that you can't get quite as much current out of them, so they might not be able to power some larger starter motors.
I wish this mainstream. The clean and green solar-mowar. Imagine the amount the money and gasoline that would be saved with this setup. Plus, if this was widely applied and worth it, the extra energy can go into the grid.
Here in europe robot mowers are really popular. Put one in my yard this year. Little bugger mows 1800 square meters flawlessly and when you slap some solar on roof it is renewable local energy ( mine mows only daytime). Its actually same price to buy robot than big ride on mower.
This is exactly what I was planning to build! I never considered solar, but I'm pleasantly surprised that it works, and I wasn't thinking about how it doesn't need to get charged faster than once a week.
there's something wholesome about how nonchalant you went "Oh, just shredded my merch.", kept it in the video, and even edited in subtitles for it. How many more stupid things happened in your videos you didn't show? :D
Colin: "... these are commercial ones obviously... " Me: *laughs in American* but seriously I have neighbors that have yards barely bigger than his and use a riding mower
@@richf5967 Not a bad plan. All math done, a robot mower has to be cheaper than having a kid of your own to mow the lawn, and may even save versus hiring another neighbor's kid to mow it.
I use one for a 0.33 acre property. Overkill, but I get it done in under an hour which greatly helps reduce my weekly household maintenance time. They also can pull trailers, till a small garden, plow the snow off the driveway, etc. They're super useful to have around for more than just mowing grass. I recently did some levelling of my lawn and just used the mower to pack the dirt. They call them lawn-tractors for a reason!
So it looks like i've made something useful haha. FEAR NOT PEOPLE TUNNEL UPDATE NEXT VIDEO

This is actually awesome, grass grows with sun and water, so with faster grass growth you're getting more power to the batteries as well, and when there's little sun, the grass won't grow so much.
that's a fantastic way to look at it
SMH, grass grows better in indirect sunlight.

Putting solar panels on EVs is a dumb marketing gimmick, but this is actually a really good idea.
Brilliant! And my favourite thing is I just know the engine that came out has gone in a box under a workbench somewhere for future shenanigans!

As if there’s space under a bench😆😂
I electrified my LM years ago by installing a tall pole in the middle of my yard with a 90 degrees, rotating extension which has a cable on it, which goes to the lawn mower. Haven't looked back since, 220v motor off an energy efficient (at the time) washing machine. Has the original brains modified to act as a speed controller. The programmer is stuck in the spin cycle where i can affect the speed at any time, thus giving me anything from crawl to zip, through a gearbox. It's quiet, actually cheaper than running the equivalent petrol variant (which i do once in a blue moon when power is out for whatever reason) and it's clean. Zero maintenance in 7 years other than oiling the bearings.
That is pretty cool.
I have a big enough lawn that this mower would be ideal except for the fact that my mower is paid for and investing in a conversion kit will defeat the the cost of building a new or buying a new mower. There is a 48v Ryobi zero turn mower and they cost 5k. Even if I spend 1k to convert my existing mower to batteries It would take more than 10 years of buying gas to fuel it. Now I will keep my eye open for a broken one that I can pick up for next to nothing and maybe work something out with it. I might even look for some of the cordless push mowers. I am sure they break from time to time and people just buy new ones. That might be an option for parts or something. Might even be able to make a deck with the push mowers and use some sort of mobility scooter for the drive section.
i concur. 1000% right!
I have a round lawn, a normal mower, a plug to a drum in the middle of the lawn, I tape the handle shut and put the whole thing on a timer so it stops when it gets to the middle.
(in my dreams)
@@anonimushbosh They do have robot mowers that are fairly cheap around 1k. Provided you have a set up lawn they are easy to use and install.
Before I bought my new house I had a yard that was going to buy one of those mowers and put it in there. Depending on the one you get you can set it up in a number of ways, I was going to add some 2x6 boards to block out some things and raise up those areas this way it makes it super easy for the robot to mow stuff. My place now is just too large I have 3 acres to maintain which I do that about every 2 weeks. Though my area around the house is getting weed barrier and stone put in. I do not need grass close to my house and this also lets me let the other grass grow wild. I am also replacing normal grass with short buffalo grass. Which if left un cut is still short and looks fine. I have a few sections growing in the yards now and going to get more seed next year and plant more as well as tranplanting plugs.

There is sooo much work behind this seemingly short video. Kudos and praise for all that!
If the charging station produces more power than the mower expends in an average day, then how about taking the Subnautica approach and making the power cells easily removable; you could have a bank of spare cells charging in the shed whilst a couple permanent cells top up overnight. You could then even use the rechargeable cells in other projects too.
You sir are making too much sense for home inventions
Another good idea would be to have them charge other electric lawn equipment like a weed eater, and maybe power some nighttime lighting
Or feed back into the house at night when it reaches a certain threshold?
^^^^^^^^^^^^
What he said lol
Night time is generally dark, thus rendering the solar panels unable to generate electricity.
Improvements I would add is some kind of gauge that tells you the battery capacity and how much longer you have until the batteries die on the machine itself
i think that he already has that. he knew at all times how much power is in the machine
With the size of his yard, he certainly doesn't need to worry about range
He used some shitty lead acid batteries. Why he didn't go with LifePO4 is beyond me..

Oh no, he's growing up.
The newspaper headlines: "Colin finally makes less noise and helps community by cutting grass"
I am genuinely impressed with this project, I was a grass machinery engineer for over twenty years, retired now.
Back in the 80s I had a design for a smaller robotic mower that worked on similar principals but never got round to developing it, this ride on with a decent lithium battery pack ought to change the commercial grass cutting industry.
Oh definitely and I'm sure that it wouldn't be too difficult to have this charge from the car inbetween jobs so the battery can last a full day of work and even if this were to be charged from non renewable energy it would still be more efficient than petrol (the reason is that despite the energy density of petrol the engines are incredibly inefficient due to their size and method of generation (cars are typically 30-35% with lawnmower engines being very much less so) where as coal powerstations are more efficient use to their size and method of energy conversion (40 to 45% and thats presuming 100% coal which is super rare)
There are plenty of big companies making battery rideon mowers Ryobi have 3 different types, normal and zero turn.
This is a genuinely good idea Colin! Not only that, but your version smells a lot better (everyone can always smell when people are doing yard work with gas machinery, the exhaust fumes smell terrible), and because it's quieter, that means neighbors and such won't be disturbed by the loud sound. This is a genuine improvement. You should sell these. People would genuinely buy them.

That is all well and good for those of us who have a "lawn tractor" BUT there are differences between a "garden tractor" and a "lawn tractor" here in the States!! A Garden Tractor in fact looks like a lawn tractor but they are very different animals indeed!! You see a Garden Tractor, has attachments like snowblowers, plows, tiller options and other add ons allowing you to do way more than just "mow the lawn" and before I forget YES you can get a lawn mower for a garden tractor as well too!!
My point is I used to own a Garden Tractor.....and it was always working on some project I had!! I might drag my car around the yard with it, when my car was broke down!! OR I would hook a wagon to it, while doing work in my garden or removing or planting a tree!! And sure I would even mow the lawn with my garden tractor weekly when I owned my property..........but it hardly if ever just "sat around" for a week doing nothing at all between mowing that is!!
Wow, a riding mower looks almost strange without the branding labels.

This is an amazing build, and commercially viable, particularly if sold with the charging shed!
I'd buy it.

Don't you mean sold with the Solar-mowar-chargar!
branding was still on the steering wheel ;p I knew what it was the first frame though, since my company sells them. They do also make electric lawn mowers in the same form.
It probably took every ounce of self-control he had in him to NOT add a homemade jet engine and rocket boosters to it.
Can't blame him, if given the option, most people would add those things.
Well, if he wants to make it a hybrid, he could always find a micro turbine with a PTO to turn an alternator or generator to make electricity to power it.

Wait a minute, this isn't nearly as life-threatening as it could be. Almost forgot what channel I was watching.

The only things I would add to the oackage was an inverter and outlet on the mower to run a weed eater, hedge trimmer, or electric chainsaw. A proper park/yard maintenance tool. Add a outlet to the shed as well to be able to put the excess power produced by the panels to use after the batteries are charged. The premium package. A very impressive build. So quiet. A Solar Stealth Mowar.
This is genuinely genius. Smart packaging (a sturdy wooden crate) could be repurposed as the shed/docking station, meaning nothing is wasted, you just take the solar panels out, fix them together as the roof, all already wired up just plug and play.
wonderful tech demo! would love to see this scaled up. This perfectly shows how the logistics of solar tractors work, could be done with larger farm equip. imagine the torque!
Farm equipment generally gets run 16+ hours a day during harvest. I don't think batteries are up for that yet. Batter powered lawn mower are far more logical.
@@crissd8283 Large farm equipment could be designed with swappable batterie systems then farmers could have a number of solar arrays/battery charging and swap stations strategically placed over their land.
A company called John Deere have an electric tractor that runs for 4.5 hours on one charge, something like that with swappable batteries would do the trick. They also have autonomous and semi-autonomus versions so the whole swapping process could be completed automated.
Sorry, won't work (for now). A large farm would need so much power you would need a whole yard of batteries. Imagine for a 500acres farm I chew easyly during harvest (2 harvester, 3 tractors for transport, 1 loader, 1 to prepare the field) 1200l diesel/day. Preparing the soil with 2 large tractors also uses the same quantity.
Check out fully charged, they did a video on an electric tractor that was in country file
Just got to love Colin's enthusiasm. You can really tell when his heart is into something.
The charging shed for your solar mower and all your electric tools. Weed wacker, chainsaw, etc. love your videos!
This has got to be one of the most sensible ideas you have ever come up with.
Not only have you created a Eco friendly Mowar it even reduces noise pollution with a cool charging station.
👍🏻 could not find any green fingers.
You really shine when you highlight the intricacies and attention to detail of your fabrication. It would be nice to see you get back to your roots a little bit in that way. IMHO.
Now Colin just needs to add a flame thrower to incinerate the grass clippings then it will be a true Furze machine!
If Colin continues to fill his garden with stuff at this pace, he soon won't be needing a mower anyway
So Colin, this is what you've been doing instead of digging the tunnels
waiting for sponsors the tunnels project :)
@@sikhbikersoflondon ah makes sense, probably is really expensive
Sad
🤣
@good one Nice bait
Great idea! I would change one thing. The roof on the shed I would make a monoslope style roof, sloped in the direction and angle that's best for solar power in your part of the world.
A very practical use for solar. Bravo! But I have two suggestions. First, can you put gauges on the console so the user would know the state of charge all the time? Second, assuming you are out mowing and have finished but are far away from the charging shed, putting a switch that would shuttle the remaining charge in the front batteries to the read drive would ensure being able to get back home. Anyway, good job!
Or just a bypass for the auto shutoff. Allowing you to drive short distances even if the batteries have already hit the minimum charge in the ESC
Been waiting for someone to sell a conversion kit to do this! Ryobi, and other major companies already selling them.
Colin mean green mowers here in the US has lithium powered commercial grade electric mowers, with solar roof options!
E-Go also; those 40amp and 56amp batteries are compact and powerful; I expect Colin could do a lot of damage with those!
@@lairdcummings9092 I think you can load up to 6 x 56V batteries in the E-Go riding mower. Should go for a while.
@@Kenjh71 yep. We sell 'em. Advertised as "up to three acres." I'll bet there are a lot of caveats in that claim, but even if it's twice as optimistic as reality, it's impressive as heck.
At us$5k per, we sold every one that came in within days. Landscapers love them... They can start cutting lawns as soon as it's light enough to see, without disturbing anyone. Puts two or even three hours onto their daily schedule - that's a lot of extra income.
Can't believe something like this hasn't become common place, very useful, very very good idea Colin, entertaining as always, keep up the good work!!
Electric lawnmowers are freaking awesome. I have an 80v push mower, the battery lasts 45 minutes. With two batteries, I can easily mow my entire lawn in around an hour and half, which is the same speed as non-electric. And my batteries also work for my weedwacker, leaf blower, and hedge trimmer! They're awesome!!!
electric lawnmowers are around for quite some time?!
Ryobi makes an electric zero turn mower
@@jerri0401 fair, I more meant the entire setup of a solar charge station and electric ride-on mower, for large areas of grass. The solar aspect especially, will charge better in summer, when grass grows more, when you don't need it as much, don't worry, it's charging a lot slower anyway... and you don't need it everyday in case of a few cloudy days...
I love Colins house- a house made out of ticky tacky looking all the same just as everyone else, and PURE INSANITY underneath.
You don't really think that is his real house anymore?
For sure he moved to a villa with amounts of money he is making.
@@N0N0111 Why would he? Why would anyone go through the trouble of digging a bunker that's better than most normal above ground house extensions, digging a tunnel system connecting the house and shed and bunker all together, a retractable roof over the area next to the house... only to go live in a boring tunnelless, bunkerless villa?
This is actually one of the most genius realistic things you've done. Have solar panels on top of your lawn equipment shed to charge all your battery powered stuff. It takes nothing from the grid, doesn't require running any power from the house. Start-up costs might be a bit higher than the average home owner may be willing to invest in. But this would be a prime opportunity for a company to offer a professional install/DIY assembly solar shed kit with financing and can also include a range of powered lawn equipment.
This could be a great application for used ev batteries. Even after beeing "not useful anymore" in cars they can be used probably up to 10 more years in these kind of projects.
probably better for home energy storage or just recycling them.
That wouldn’t work. The way they degrade makes them not useful anymore, period. They can be recycled or recelled though

Thanks!
I've wanted to do this exact thing myself for several years now, and I am so excited to see it done by someone -and done well!
How about a lawnmower that runs on the grass it cuts itself? For example with a methane biodigester and a combustion engine.
Although now that I think about it, that's how a goat works, which is also suitable for mowing the lawn and fertilising it.
To be fair that's what the gasifier mower was going to do.
Still combustion based - not really helping with the emissions problem
@@classicambo9781 but the grass would have absorbed the carbon content in order to grow, so emissions wise its totally neutral - IF (and its a big if) it doesn't need any fuel besides the grass its cutting.
Lol
I think you can also make ethanol from grass, so long as you jet it right and use alcohol safe fuel system components, either should work.
This is why I love his videos.
Collins prediction: work for 20 mins, a week or two to charge
Reality: works well over an hour, takes about two days to charge.
Really good vid, keep em coming
I put a solar battery charger on my car today. It's total size is lucky to be 48x18cm and has 72 4x1.5cm cells in a 18x4 array, has a float voltage of just under 18v and can charge a battery at half an amp it has massively exceeded my expectations to say the least. I was expecting it to charge a fully flat battery in 4 or 5 days. In reality it probably will be charged by tomorrow afternoon. I guess that goes to show that solar has far greater capabilities than it is given credit for.
As Always Not only a Great idea but presented in the BRILLIANT COLIN FURZE WAY! Mower company's take note!! This is how you do it!!!!!!!
Colin, I love your videos - But I would love to see a much more "technical" version of them, like how did you wire the batteries?

You're absolutely brilliant, and I'd love to learn from you anyway I can.
Agreed! This seems like a really cool projects and I have a riding lawn mower that would probably actually make sense to do this to. Maybe he will pit something on his website?

Lots of surplus energy through those panels when sunny. Make sense to have a battery operated hot tub next door to the shed. Hot and sweaty after loads of mowing, have a chill in the hot tub after.
This is probably the quietest Colin's ever been.
This is cool and all Colin but cub cadet, same company that makes the one you brought in at the beginning, already makes that exact mower in an electric model. All you really had to do was build a solar charge station for one of those lol.
Exactly what I was thinking. There are several companies now that are making electric mowers both riding and push. Though still that doesn't take away from the fact he completely swapped one over and did all the engineering and everything.
yes because that would be entertaining
yeah, and I think they have lithium iron phosphate batteries. Dam expencive though. Prefer the ryobi zeroturn electric mower because it uses 40v battery packs that can be used in other ryobi power equipment.
Well his version using lead acid batteries just proves electric has been viable MUCH longer than lithium batteries have been around!
Lead Acid batteries, when built properly (not the modern crap you get) and maintained, can last thousands of cycles and are already one of the most recycled products in industry. They are a bit heavy for vehicle use, but they would be almost perfect for a cheap grid scale energy storage. They are so simple and cheap compared to lithium for how much energy they store and how robust they are.

b) this alreads exists, but smarter. There are lawn mower robots that have a solar charging station, the difference being they don't have to carry a 80kg human driver, thus can reduce the motor and batteries massively.
c) taking b) into account, this could be a tough product to sell. These would basically only sell to those people who _like_ to mow their lawn manually.
@@ben_1 Robot mowers, at least the ones available right now, are not suitable for every situation. In some cases you don't want to have them around for liability reasons, and since they're much slower at getting the job done (due to literally driving slow and due to pathing inefficiencies) you also don't want them in heavily used areas, since you don't want the mower around when people are actually using the space.
Let’s be honest. When he goes back to the tunnel project he needs a lift out of it because a ladder is boring and not Colin

Tunnel tunnel tunnel!!!!
Honestly speaking, you could use the other panels to give power to other things in your home. Like charge up a battery bank and have your tools pull from them before pulling from the power grid
Lead-acid batteries can only run down to 50% of their capacity, every time the charge goes lower than that you compromise their internal stability and ultimately their life. I'd suggest to have a monitor on the dash so you can tell when that's the case.
The speed controllers he is using also have an option to disable the motor when the battery voltage under load goes to low at a level that can be programed in and some of these controllers also support reserve and a host of canbus options for reading the controller data and adding instrumentation for the driver.
He should add LiFePO4 prismatic cells in this thing. Extremely cheap nowadays, it will have 3 times the energy density of lead acid and have thousands of cycles even when doing an 80% to 90% depth of discharge.
Lead acid car batteries yes. Deep cycle. No.
That's certainly true for a typical car battery, which is designed to provide short but intense bursts of power for the starter motors on car engines. Batteries designed this way have a large number of very thin electrode plates inside, which gives the maximum possible current, which can be several hundred or maybe even 1000 amps depending on the physical size of the battery. But of course because of this design, deep discharge can build up so much lead sulfate on the plates that they can touch each other or get bent out of shape. Then you've got a shorted cell which makes the whole battery useless, leaving it worth perhaps £5 to a scrap metal dealer but not much more.
However, you can get deep-cycle sealed lead-acid batteries which are specifically designed to be discharged up to 90% or sometimes more. The battery chemistry is the same, but the internal construction is not: A deep cycle battery has a smaller number of much larger electrode plates, with enough space between them to allow plenty of lead sulfate to build up without damaging the cells. The sulfuric acid electrolyte is also usually immobilised in a sealed battery, either by gelling it with silica flour (aka fumed silica) or by absorbing it with woven glass fibre matting. This allows the battery to be mounted sideways or even upside down if you like, but the glass fibre matting helps to keep the cells rigid, stops them bending and prevents sulfate crystals growing across the gaps between electrodes. These are far more reliable and tolerate repeated deep discharge, the only downside being that you can't get quite as much current out of them, so they might not be able to power some larger starter motors.

I wish this mainstream. The clean and green solar-mowar. Imagine the amount the money and gasoline that would be saved with this setup. Plus, if this was widely applied and worth it, the extra energy can go into the grid.
Cub Cadet already has an electric ride on mower in the US. Seems easy to adapt a solar shed to that.
Here in europe robot mowers are really popular. Put one in my yard this year. Little bugger mows 1800 square meters flawlessly and when you slap some solar on roof it is renewable local energy ( mine mows only daytime). Its actually same price to buy robot than big ride on mower.
I've got an electric self-propelled push mower and it's really nice. Quiet enough I can actually run it at night. It even has headlights!
Neighbors: "Colin! Are you alive? Why is it so quiet?"
This should be a commercial product of its own!
I can definitely see the solar shed + electric mower combo being popular in the future.
This is exactly what I was planning to build! I never considered solar, but I'm pleasantly surprised that it works, and I wasn't thinking about how it doesn't need to get charged faster than once a week.
It's brilliant, especially with the charging shed.
This is the best idea I've heard in a very long time. You could sell these as kits with the housing and the mower. This is really brilliant colin.

@@richf5967 Not a bad plan. All math done, a robot mower has to be cheaper than having a kid of your own to mow the lawn, and may even save versus hiring another neighbor's kid to mow it.
I use one for a 0.33 acre property. Overkill, but I get it done in under an hour which greatly helps reduce my weekly household maintenance time. They also can pull trailers, till a small garden, plow the snow off the driveway, etc. They're super useful to have around for more than just mowing grass. I recently did some levelling of my lawn and just used the mower to pack the dirt. They call them lawn-tractors for a reason!
