If you're getting a lot from my videos, and would like to support me in my efforts to help everyone, here are a couple of ways to do this:
1. You could www.buymeacoffee.com/GaryDoes... :-)
2. If you're thinking of switching energy supplier to Octopus Energy. If you call them and give them my referral code ("blue-wind-201") and my name ("Gary Waite") and we'll both get a £50 credit to our accounts as a result! share.octopus.energy/blue-win...
I believe Octopus Energy is doing more than any other energy company in the UK to take us forward to a bright renewable future, and I'll make making reference to them and their initiatives in future videos.
For UK viewers, this highly recommended Facebook Group is a great place to learn about solar, ask questions, and even get opinions from members on quotations you've received: / 2197329430289466

1. In the video I make reference to MCS, a certification scheme, normally required by energy providers before they can provide certain services like paid export. There are now other similar schemes, including FlexOrb that energy providers are accepting as well. Competition in this area is good as it will help keep the pricing of these schemes down.
2. Also in the video, I talk about the effect of shading on a single panel affecting all the other panels. In actual fact, it depends of the type of shading. If the shading is hard (for example, from a chimney or another building) then the panel is able to protect itself (via bypass diodes) without affecting any the other panels in the string. If the shading is diffuse or limited (for example, a TV antenna or cable) then this could well affect the other panels because that kind of shading is not sufficient to activate the bypass diodes in that panel. See this video for a more complete explanation: th-cam.com/video/9GvhDhCSJgo/w-d-xo.html
Thanks for the clarification. Can I suggest you pin this comment to the top?
One of the companies I priced for Solar panels was $65,000 for my home, It would take me 36 years to pay for that at the cost of what I pay for my light bill now.
@docbrown6550 most states have rebates and SRECs available to reduce that burden. Most of my analysis came back at a 5 year pay for itself cost.
@@AnthonyAlvarado78 My light bill is around $100 a month, at a cost of $65,000, it is not feasible in any form or fashion to buy solar. Our state does not help that much to make enough of a difference. It would actually take me more than 36 years to pay that off, at the cost of what I'm paying now for my light bill.
That's not true anymore. Modern technology limits it to the one panel
Gary. Without question, the most useful video I have ever seen. Professional, detailed yet easy to follow and extremely informative. Thank you for taking the time to make this very comprehensive video that obviously took a lot of time and effort to make.
Hi James, thanks very much for taking the time to provide feedback. I’m humbled. Yeah, I didn’t realise how long the videos would take - lol! I’m half-way through the next one now - hope you find it useful 👍🏻
I second that statement. I was just looking to get solar, but I can now be a consultant. 🤗
Gary I am in Ireland and just wanted to thank you for this great resource, ever think about an Ireland special
Indeed....clear, concise delivered at an easily digestable pace..... professionally.
Yes. I will second that.
The most informative, clear and succinct video on Solar power I have seen. Well done Gary.
Thanks very much for this great feedback! :-)
Hi Gary. I've been searching through the various YT channels on this. Yours is the first one that has content I was looking for. I see you are just starting YT, and your delivery approach, the detail provided struck home for me. Thank you and I wish you the best. Great stuff!
Thanks very much for the kind words, John! Many people I've worked with over the years have told me I was pretty good at explain complex things in an easy way. And I was thinking about getting my own solar installation anyway, I thought why not share some of the knowledge I gained along the way :-) It turned out to be a lot of hard hours to put each video together, but feedback like this really makes it all worthwhile - thank you!
I second John, one of the best solar information video focus on UK market
I third, John, just going in Solar panel (for a french installation) and your video is cristal clear with all the expected details it should be! Thanks a lot for your time and video
I agree
The best videos on solar PV TH-cam -so far
Clear-headed, logical with no axe to grind. Thank you, Gary
Thanks Chris 👍🏻 yeah, there are too many Solar videos out there that are highly biased. I’ll continue to keep things neutral, especially with an upcoming video on panel shading! 😳
Great video Gary! Great to see you are still explaining complex things in a straight forward way! I've been on the solar journey for 2 years now and still learning!
Hey Mark! You found me on TH-cam! Who'd have thought, eh? :-) Thanks for the kind words - great to hear I can still do it!
I'll text you early next week if that's ok. Would love to catch up with you :-)
Thanks for the very clear explanation of various solar PV installations. You have shown me exactly what I have been looking for. Excellent.
Thanks Peter - glad to be of service! 😀
This is awesome. So much information that no one else seems to know/share on their channels!
Thank you - that means a lot to me!
Gary - the man of my dreams :). We had solar installed about a decade ago by a company that has subsequently gone out of business (and sold our contact details so we have been regularly approached by other companies ever since). I wish I had seen your videos back then. We had no explanation of how our system worked and how to maximise our use of it, so haven't really been using it well. We've also had a few blips - mostly with the Solar I-boost diverter - and found it stupidly hard to find help. Thanks for your empowering and professional video. Really good to see that not everyone in this field is a cowboy!
Hi Clare, I wish I had got into Solar years before as well! Thanks for the very kind words 😀 I’ll keep the videos coming…
Thanks Gary, these two videos were exactly what I needed.
That's so great to hear, Lee! Cheers :-)
Thank you Gary. The best YT video on the subject I've come across yet. You have a perfect voice for narration and your graphics are spot on. Keep it up. I have now subscribed and will be checking all your other vids.
Wow - that’s praise indeed! Thank you 🙏 😀 Next video just published 👍🏻
Thank you so much for explaining this complicated subject in a clear and concise way.
Many thanks - it was my pleasure! 😀👍🏻
This is the best ‘introduction to Solar’ video I’ve seen by far. Thanks for all the useful info!
Thanks Marios - that's very kind of you to say :-)
Finding the videos fascinating. Thanks Gary.
My pleasure, John. It’s a lot of work but feedback like this helps me keep going 😀
Ive watched dozens of solar videos and this is the best one I have seen. Thank you so much ;)
That's amazing feedback, Robbie - thank you!
Very informative and interesting. Well produced and presented. Thank you.
Thank you :-) it's great to get feedback like this. Next video in the series coming in a week or so!
A little correction, microinverters should not be the more expensive option, it should be the same as a system that use optimizers, let says is buy a 10kw String inverter for £2.000 (SolarEdge) and you install 27 panels (370w each) for a 9,9kW system array, when you divide 2.000/27= $75, then an optimizer will cost you around $60 (or more) each, the total is around £135+ per panel, which is very similar to a microinverter like Enphase IQ7A, £160 each (and now cheaper with the new IQ8 series).
This is just an example, the String Inverter + Optimizers is more expensive when you install a smaller array system, because a 5kW won't cost you half price of a 10kW S. Inverter, so the cost per panel is a little higher, and keep in mind when you use that setup, you have 3 points of failure (panel/optimizer/inverter), while with a microinverter you only have 2, besides Enphase provide a 25 years of warranty.
Hi Federico, thanks for the extra analysis. Great to see that microinverters fare better against other solutions than I thought :-)
Thank you Gary. An excellent video for anyone new to solar
You’re very kind, Derek - thank you! 🙏
Very insightful video full of valuable guidance. A must watch for everyone. Well done in the creating high quality content Gary

Excellent first two videos. Gary, hope you will do some more. . You are the right person , with the right channel at the right time to be offering potential individual household solutions on the energy crisis. Good luck with it
Hi Dennis, thanks very much - wow!
It's a lot of work, but if I can help even just a few people make the leap and cut their energy bills over time, I'll be well happy! Next video out very soon...
@@GaryDoesSolar Sounds good😀
Great video thanks.
I've always understood solar but never quite understood the various power ratings etc of the inverters, but this video is perfectly simplified and now I understand them too! Many thanks.
Great to hear that my videos are helping you with your understanding! Thanks for letting me know :-)
Really practical and helpful for those of us investigating solar options. Brilliant exposition of the technicalities.
Thanks Peter - it’s what I wanted to achieve so your feedback means a lot! 😀
Thank you sir for this very information and thorough presentation on Solar Energy Generation. You covered almost everything in professional details. I liked your channel and I appreciate your sharing with the general public. Thank you very much.
You are most welcome, Shaider 🙏 thanks for watching 👍🏻
Professor Gary! A really valuable video, your delivery is excellent. Thank you.
Thanks and you’re most welcome! 😀😀😀
Very detailed and super useful👍👍
Thanks Nigel :-) And great to hear!
Special thanks for this video - we are at the beginning of the process so getting some coaching and advice on system design and installers is timely.
You're very welcome, Rick - and all the best with your solar journey. I have other videos looking into the different aspects, which may be of help too :-)
Magnificent video. Excellent explanation.
That's very kind of you to say - thank you! :-)
Thank you for producing an excellent video which I found to be very clear and simple to understand.
Like many others I am starting to think seriously about installing solar and your explanations have given me a basic grasp of the components used, their functions and various options. It will also enable me to have some rather more informed discussions with potential installers.
Thank you so much for this feedback, John. My next video on calculating the payback period should be ready in a week or so. Hope you enjoy!
Excellent guide in simple language, think we are on-track with our installer so far!
That’s great to hear, Mike! Thank you 🙏
Awesome!!! Thank you Gary
You’re most welcome! 😀👍🏻
Excellent video. Very informative. I did not realise there was so much to consider.
Thanks, Antony - great to hear the video was useful to you. Yeah, the deeper you research, the more there is to learn! Luckily, it's not rocket science though, so everyone can what they need to on the tech :-)
This is very comprehensive..thank you for all the effort you've put into making this video. I've finally understood the difference between AC coupled and DC coupled!
Hi Afnan, it was all my pleasure! People have told me that I'm very good at explaining complex topics in a simple way (one of the reasons I started making these videos in fact), and so I'm very happy to hear my work has helped you too :-)
@@GaryDoesSolar Helped me too! Thanks Gary
Gary, being in the process of "going solar" and getting quotes, I've found your video most helpful in some respects so great thanks for that. I think I prefer the idea of microinverters with an AC coupled battery (despite the potential power losses), i'm not sure the price difference from a string inverter is so pronounced anymore, particularly a string inverter with optimizers and most microinverters have a 25 year guarantee nowadays (Enphase) versus a string inverters 10 year to allay fears of inaccessible repairs. I presume this means peak power usage (without grid) is limited to ARRAY + BATTERY in daytime and BATTERY alone in the evenings. I noted the batteries in my quotes, (Give Energy, Solax, Alpha Smile B3) only have a maximum charge/discharge rate of 2.68 Kw. If my house is using (TV-300, Microwave-1000, Fridge-200, WIne Cooler-100, Lights - 150, PC-150) and I put the kettle on at 3000, will that switch seamlessly to drawing from the grid or am I likely to experience difficulties with appliances? I suspect I may be getting mixed up with off grid systems there? Do you see that level of battery discharge rate as a problem if one is desperate to not draw from the grid if possible? Are discharge rates of that magnitude standard across the industry or can you get larger, in general those figures don't appear to be a readily available from an internet search although I can find Tesla Powewall is 5Kw surging to 7.5Kw? I suspect I will be more conscious of using other high power appliances during daytime if possible but I do enjoy a cup of tea in the evening! Thanks again.
You'll find that your solar and battery system will seamlessly provide electricity to your appliances both with and without any grid requirement. And I don't know if you read about the latest Tesla Powerwall 3, but it's got a 11kW discharge rate, so no worries (at all) You'll be able to have that cup of tea and not draw anything from the grid :-)
I have Gary and it has a lovely £11,500 price tag and a waiting list over a year long when it eventually gets here so I'm priced right out of that one. I'm thinking about 2 x SolaX 5.8 LFP offering, I believe I've read that their lower end power output is increased if 2 batteries are wired in series together as master and slave but not sure if that's true, do you know?@@GaryDoesSolar
👏 👏 👏 great stuff Gary...excellent video
Thank you! :-)
Hi Gary, As with everyone else who've watched your videos, I am so grateful to you for providing this extremely well-presented information at exactly the right time for me. It was amazing that, as I watched, a question would come into my mind only for you to cover it almost immediately!
I'm on the brink of making the important decisions, so these videos are perfect. Thanks again.
Hi Phil, thanks for taking the time to make this comment - wow! I’m humbled. And glad to have got round to it all in time for you! 😀 I’ve just published my next video which you might find useful too 👍🏻
@@GaryDoesSolar Thanks Gary, I'll watch it now. Best wishes, Phil
Great info. Thanks.
You’re very welcome 😊
Top quality video, thank you for this one, Gary.
You’re most welcome - thanks for the great feedback!
Thanks I learned a lot. Nice clear presentation. Well done
Thanks Stephen 😀 next video should be up tomorrow 👍🏻
Highly informative, communicated very well in a very easy to understand language. Well done and thank you Gary.
That's praise indeed - thank you! And you're most welcome :-)
Superb video. Informative and very helpful. Thank you.

Brilliant video, very well delivered.
Many thanks! Great to get feedback like this 😀
Thank you so much for your awesome video 😊
Really happy your enjoyed! Cheers :-)
Excellent very clear to understand. I will go through all of videos, thanks
Thank you, and much appreciated. I’ve got a new video coming out in a week or two. Cheers, Gary
Thanks Gary, comprehensive I am sharing already 👍👌
My pleasure, Richard - and thanks for sharing it! :-)
I am currently looking at Solar and your videos are providing a great source of information.
Thanks Gary, for taking the time to comment - that's really great to hear :-) All the best with your plans!
I called a local solar installer in my area, and was told "We will call you back to set up an appointment to look over your project, and give you a quote!"
That was 9 years ago, and I still haven't got a call back from them to this day!!
Likewise I called a different place, that seemed more excited to "work with me", and again this was nine years ago (a month after I called the first place) and they took my name, phone number and got my address!! They told me, "we will have somebody call you when an appointment slot if available!"!!!
A few days later they called me and asked "We can come over Saturday, and look at your project!"! I told them "Great I will see you Saturday!"!! And again that was nine years ago......nobody has shown up yet!!
The point is, if I am going to have solar installed, apparently I will have to do it myself!! Because the companies I call, can't be bothered actually to call back OR show up!!!
Such a shame the companies you contacted back then were not more responsive. Things are different now, so worth another shot...
Gary, Thank you so much for this video, I'm just starting on the solar/battery storage learning trail and I found this video remarkably comprehensive in explaining in, laymans terms, many of the questions I needed answered and the most surprising thing of all was I was expecting to find at the end of the video some sort of promotion for this or that particular equipment or that you were an installer, but no, just putting this info out there without looking for anything in return, quite a revelation in todays society, so again many thanks for your time and effort. best regards
Thanks Quintin - yeah, my driver for making the videos was primarily all about saving people tons of time wading through the minefield of information (and misinformation) about solar technology. If I can make any money on ad revenue etc. then that will go towards improving my recording setup (which is currently very basic). Feedback like this really makes it all worthwhile, so thank you for taking the time to comment! ❤️
Gary, two excellent videos, well done. Are you able to make an in-depth video on the survey process so that customers are aware of the whole process. Also, a dive into the different manufacturers and different warranty's offered would be helpful. Keep up the good work!!
Thanks Mike - it’s great to get feedback like this 😀 I’ll add your suggestions to my list of potential future videos - it’s a growing list, but I do want to cover the topics of most interest! 👍🏻
Wow. The perfect balance of simple and detailed.
Ive done a fair bit off research and was really impressed with what ISNT in the video.
Youre managed to include all the end steps of my research with out all the confusing intermediate knowledge to get there.
Ok, that's praise indeed! Thank you, Simon :-)
thanks Gary , well done.
Cheers William - thanks for taking the time to watch :-)
Excellent. Thank you
My pleasure - thanks for taking the time to watch :-)
OMG had to pause the video to just say "THANK YOU!"
Thank you for taking time to explain this whole solar thing clearly. I can finally wrap my head around what a whole system looks like after spending hours going through other people vid.
You're most welcome, and so great to hear feedback like this. You've made my day! :-)
