I am going to gently suggest that vinylester resin would be better that epoxy because epoxy breaks down in UV light. It discolored right away and then will become as brittle and fragile as the solar plates you are trying to protect. If you use epoxy be sure it has UV inhibitors in its formulation. Or find an additive. Also gentle vacuuming between plastic sheets will remove the bubbles and gently force epoxy into the gap between backing and solar cell.
@@DRYAVUZORNEK it’s even more confusing when you add polyester resin, which is also preferable to epoxy in terms of resistance to UV degradation. But like a lot of things there is no one single best. The final choice is always with which set of compromises are you most comfortable?
For a more finish look, place tape around the plastic, then fill epoxy to the edge. Pull off the tape in a few hours and the edge will be straight and uniform. Faster to fill because you can mix a large batch and pour in the epoxy, especially if you do a large number of these.
if you're in the US, definitely look at the instructions on your epoxy resin. the epoxy i've used starts hardening up around 10 minutes, so it would never sit for that long for air bubbles to escape. depending on the project, if your surfaces are completely coated (meaning no paper on the sides) you can use a lighter or blow torch to remove the bubbles, just a quick wand over with heat. also, the CO2 from your breath will remove air bubbles.. not by blowing on it, but by letting out a "huhhhh" breath over it... but to make a ton of solar panels, you might pass out doing that! : )
Thank! There are various types of epoxy. I use the classic one which at room temperature hardens completely for 24 hours. Resins that are harder quickly are not suitable in this case. The best way to remove the bubbles is to place the resin in a vacuum chamber. But for a slow resin, this is not required, you can just wait 20-30 minutes.
I was thinking of making a modular plastic frame for solar cells with contacts going down the plastic... Would make it a lot easier in my mind as you just place the cell carefully and coat it with a thin amount of epoxy. I also want to try putting epoxy resin in a vacuum with the solar cell, I just have the fear it might crack, but for 24 cents I can't complain.
Hi, I like the video, good instruction on how to make these cells into usable assemblies. Can I suggest you scribe or cut a line in the plastic under the cell where the anode wire goes, so the cell lays flat on the plastic square, this will take most of the stress off the cell structure.
Yes, this is great advice! I thought about it already when I made the video. This advice has already been given in the comments. I'm glad that my viewers are so smart. 👍
the current supplied by each cell is tiny, id use a single strand of the thinnest multistrand i could find, and with 50 cells ive set them all ona single baord either 5x10 or 7x7. Then you solder a single strand on the bottom, and then epoxy them in place , then solder the top connector to its neighbour, or run a strand of bare wire down between the rows if you are going to block parallel them, then the top coat of epoxy. Theres a dozen different ways to do it.
What is this man? You already came up with a wonderful and very useful idea. I will try to do the same, but I am afraid to fail. But, my friend, I saw that you used home lighting instead of the sun. Does the solar panel usually respond to home lighting, and how many panels will I need to charge One 3.7V battery within 24 hours? And Thank you very much for the idea 🌷👍
A propane burning torch will get the bubbles out a LOT easier and faster. Just hold it several inches away from the project and watch the bubbles pop to the surface! Also a playing card or old credit card works great for spreading the epoxy, too. Be sure to do this outdoors or in a very well ventilated area with no fire hazards around! And kids need to ASK MOM AND DAD FIRST before trying anything like this!
As someone with OCD I would like the panels to be heat sinked to a matt black metal backing. Just the panels work better when cold. I`ve got some small panels kicking about. They are so delicate. My friend broke one just picking it up. I will try this. Thank you.
HI, I saw you mention at the end of the video that you can attach 2-3-4-5 solar cells to the plastic, but I'm a novice when it comes to these things. I was wondering how you could attach multiple cells onto the same plastic.
Nicely done and informative video. Even the comments have been great on this one. Question though, if you wanted to make just a single panel or 2 for a well pump home us, which panels would you recommend that would still make economic sense (ignoring labor costs)?
4:48 in my experience of soldering, the anode solder is easier to make on this kind of surface. I used to do micro soldering in iPhones to bypass or simulate faulty chips.
If you want these for permanent outside, you must coat both sides to avoid moisture rusting the cells. Also, use glass (the plastic will degrade). Good for robots to find sunshine in the house!
Watch the video carefully: the epoxy resin is on top and around the edges, and on the back side is plastic. Such cells can be immersed in water without consequences.
grain, plastic will allow water to pass through over tIme and seasons. Especially when it degrades in the sun, and with changing pressure of night/day and contracting/expansion with temperature changes. They sell a sheet material called EVA that is impervious to water over time. It doesn't yellow in the sun. You vacuum seal it to both sides of the cell, or use glass on the bottom side. I made a 60 watt panel with EVA that has been in full sun for about 6 years with no rust, or moisture penetration. Epoxy on both sides of the cell is an alternative. The plastic might last a year in the weather. It's good, just not for long term.
I forgot to talk about wires. The insulation on a wire will allow a channel of air to enter/escape on a nightly basis as the panel heats and cools. This breathing will transport water vapor and will rust the cells near the solder joints unless you are very careful to seal the part of the insulation near the cell. When using EVA, you don't use insulated wire. Instead, you seal the EVA to the bare strips which serves as insulation.
@@TheRainHarvester You repeat the mistake of many commentators under this video. Why did you decide that these panels are for the roof of the house? If I did this for the roof of the house, the dimensions of the panels would be a bit larger. :) Solar panels are used not only for the roof of the house and not always the whole day for many years under the snow and the sun. Watch the titles of other videos on my channel and your questions will disappear. Only one example for my panels - a panel of 10 cells will give you 5 volts 400 mA - this is a great alternative to charging the phone on the beach and in the meadow. Watch the end of the video with the dough - th-cam.com/video/WWKRbpPzECc/w-d-xo.html
You mention there are no bubbles when mixing but actually there are thousands of micro-bubbles. I've been working with Epoxy a bit, and a amazing but cheap solution is just using a little spray bottle that makes fine mist with rubbing alcohol. Spray it onto the epoxy and all the bubbles disappear, it's quite satisfying, and then the Isopropyl alcohol evaporates. Try this and best! Otherwise, great idea and video. Thanks.
That`s a good tip. I bought loads of small panels and never used them. I made some automatic blinds and want to get away from power cords. Need to make at least 7 volts to power the micro controller so about 5 then.
What about bonding cells with baking soda and super glue? You can position the cells easily while the baking soda is applied, then use one drop of superglue to bond the cell in place instantly. No waiting for the superglue to dry. To break the bond on the cell, just apply heat slowly with a hair dryer. You think this would work?
You mean sharpening a soldering iron? I previously worked for about 10 years on the installation of electronics. This form of sharpening the soldering iron tip is applied at the factory.
And unlike today's fashionable form in the form of an awl, my sharpening form allows you to hold the solder on the soldering iron tip and thanks to this my left hand is free. The one who works as a sting, his left hand holds the solder. And to be able to do something else, he needs to buy a device with the name "third hand". :)
Liked and added to favorite. Maybe one day i will do it despite the fact that i never ordered from a foreign website especially from aliexpress. I suggest wearing cloth gloves and not touching the cover of the solar cells because you can leave imprints or dirt spots which can reduce the efficiency. What is more challenging is to see what kind of battery and electronic parts are needed to store the electricity, to use it later at the night for example on a veiose when you have, lets say , 50 sollar cells. Can you try such a project to store the obtained electricity for later use or to get a stable/constantly power.
For a small amount of energy at night (for example, night lights in the garden), supercapacitors may be suitable - aliexpress.com/wholesale?catId=&SearchText=supercapacitors
@@grain8314 awesome, thank you very much. Edit : youtube suggested me how to build a big battery with Li-Ion cells which provides 300 Watts , this is awesome but still expensive and advanced project requiring some special tools and an inverter for 230 V~. th-cam.com/video/6Ai5IRQbLcc/w-d-xo.html . Well, this is a suggestion for how to build a smaller one and without inverter ,maybe a Li-ion battery from a drilling machine should be enough.
Thank you, I clean with alcohol. Acetone fumes are harmful, I do not advise using it. For this reason, acetone is not sold in Molodva. Here I did not clean the rosin, because it does not affect the quality does not affect the appearance. :) Please note rosin is not visible after coating with epoxy resin.
So in general, acetone can be used to thin epoxy resins, can you not use it in this situation to both help with air bubbles and make application to the cells easier?
ok so you bought the ones that you would join together to make a whole panel with probably the wrong sort for what you want cause they are made to be joined together in series with the bought joiners you showed early on in the video and made into a panel such as a 250 watt panel etc just thought you might like to know that
