What if you chose some more reasonable background music, than this same bounce from start to finish. That's really annoying to listen to. Are you so lazy that you don't bother to choose suitable music? And with a little extra work, you could have used a knife or a dremel milling cutter to make a fair recess for the plus wire in that white washer, so it would be easy to attach the cell to the base without any bending.
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.
If you're going to make a few, you might wanna make a vacuum chamber. A bicycle tire pump with hose taken off and placed at the top via drill and tap. Then a thick piece of plastic ¼ x6x6 with a hole and an intertube inlet shoved in for the other end of the hose and a pyrex bowl with a rubber seal, thats it. Sucks those bubbs right out.

The lack of narrative is a little bit frustrating, but I guess, it may helps us keep focused when the narrator has a heavy accent... like mine :-)

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

Bravo, magnificent, what a work of precision & patience ! ! ! You could add the resin manufacturer contact in non cyrilic alphabet for those, like me, that cannot read cyrilic. 😀 Thank you for your video.
This is a resin from a Russian manufacturer, the city of Dzerzhinsk. My friend from Moscow sent this to me in Moldova. Unfortunately it is not possible to order online. But this is the best resin I have known for about 40 years! raosteklotkan.ru/catalog/poliefirnye-sistemy/komplekty-smola-i-otverditel/edp-280-detail
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.
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". :)
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.
Congratulations for your nice work!!! I liked it very much. Very, very well explained, indeed! It's 0.440 volts for each cell and about the ampers, how many miliamperes each one? Thank you for your answer.
Each cell provides 0.5 volts. The strength of the current depends on the brightness of the light, with these cells being more sensitive to infrared light. In the sun, the cells give 0.4 amps, that is, 0.2 watts each cell.
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.

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.
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!
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.
Few remarks, if I may. Since most epoxy is not UV-proof, I think you need a kind that is and that is for sale. Otherwise it turns to a bit to yellow/brown, and not shining anymore, after a while. Or protect it with a UV-coating. Made a few myself, like you, about 20 years ago and they still work fine. And why not use a vacuum to get the air out, in the cup with the epoxy? A vacuum-cleaner will do the job. Spinning it while curing, could be an option, may be, Did not try that, may be for the next solar-cells. And later on also, to get a better connection and underlaying, while curing. Takes some more epoxy, ok, but also more durability, in wheather things, like hail. A form will spares a lot of time, I think and easier to combine more cells. And please take care for the epoxy-allergy, so use gloves and a mask etc. Epoxy ressin hardly shrinks and is very resistend, so good choice and thank you for this video.
Thanks for the tips! Yes, epoxy resin is also harmful, I forgot to write. About ultraviolet: the cells that I use give better current from heat rays - infrared radiation. I showed in some videos how well they work from the candle, from the match and from the incandescent lamp. And this video as my whole channel is not for serious home-made products for the home, it is entertainment products. However, from these solar cells, you can make a battery for travel. I connected 10 cells last summer and got a current of 0.4A on charging a smartphone - th-cam.com/video/WWKRbpPzECc/w-d-xo.htmlm10s
@@legallyinsane7151 it may well be polyester resin or similar, but Epoxy is not only 50/50. Have literally bought and used several ton in stone industry , and that is used variably at less than5% to no more than 10%
Why poliester resin? and why not to spray it but apply it with toothpick? While you prepare the plastic support it is positive if you open canals for wires, that will help you stabilizing the wires easier.
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.

Do you want to use fiberglass as a base? Why not, but is it convenient to make it and will it be or is it beautiful. Or I do not understand your question? Sorry, I do not know English well.
never saw this many bubbles in epoxy, and your quality too if you just tilt your mix you get better result. next problem is epoxy turn orange after long UV radiation.
Try stirring the epoxy for 30 minutes and you will see bubbles. In order for the resin to have no divorce after curing and to look beautiful, long stirring is required. As for UV radiation, you may be right, but my method is not intended for the roof of the house and providing it with energy, it is simply unprofitable and troublesome. I make such panels for my experiments. But you can use this method for example to make a panel of 10 cells and charge your phone during a picnic. This will give 5 Volts and 400 mA, see here - th-cam.com/video/WWKRbpPzECc/w-d-xo.html
@@grain-diose not bad yeah 2W, i mix my epoxy about 2 min and it works too (iam very carefull while mixing, bubbles dont really disappear while let it sit). i like that you are not offended rather you give an solid answer. i would use polyurethane lacquer transparent for this panels
Actually, don't worry about vigorously mixing the epoxy at all, and some might recommend a heat gun or torch. Don't do either, mix well and just use a fine mist spray bottle with some 70% or higher Isopropyl alcohol.. spray it on and watch all the thousands of micro bubbles, even the ones you can't see just disappear.. it's very satisfying and a cheap but awesome solution. I wouldn't use a heat gun/torch, because introducing heat can make the epoxy set quicker, too much can actually warp the epoxy unevenly aka burning it, and again too much heat could damage the cell. Best!
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?
I wrote in the video, but I will repeat: an epoxy glue is needed that hardens in 24 hours. 15-minute, 30-minute and other fast adhesives are not suitable for this. You can try a quick epoxy glue, but I do not know what you get.
3 solar cells with 3 coils are connected in a circle. Light must go on one side more. On this side, one of the cells gives more current and turns the rotor thanks to static magnets. 2 other coils act as conductors. Then another cell with another coil becomes this place, now it gives more current and turns the rotor on.
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.
@@JimmyBaevsky Not at all. Any epoxy resin is useful, but preferably with a long curing time so that the resin has time to level before polymerization.
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.
Maybe. But these panels are not made for use on the roof of the house, especially this method is labor-intensive for such a case. I make these panels for my experiments. You can use this method to make a hiking panel for charging your smartphone by connecting 10-12 cells on one plastic.
No wax won't help as UV would go through it. UV light breaks down plastics polymers and many other compounds. Ever put for example a polyurethane in the sun? It turns to dust in 6 months. They do make UV additives for plastic and epoxy that slow down degrading like used in cars for example. Best to go with a UV rated epoxy.
I'm wondering what I am missing here. I did a quick cost calculation per watt, and just the raw solar panels (before all the other parts and labor) come out to about twice what a decent, pre-built solar panel costs. In other words, unless I'm missing something, it's cheaper to buy pre-built solar panels and save yourself all this work.
What is the Ampere rating for each cell? Video have voltage rating shown but not have Ampere rating mentioned... Please reply sir! I'm willing to buy those... And it's so important for me...please reply with Ampere rating...& how much Watt(if possible)...!
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. 👍
I think only in Russia. I brought it from Moscow. But epoxy glue is used all over the world and can be found in hardware stores. You can also find it in aircraft model clubs, epoxy with fiberglass is used to make composite materials. Other polyester resins that can be better than epoxy to coat panels also exist and are used in different areas. Industrial solar panels are made with this resin, not epoxy. See Google for more details - www.google.com/search?newwindow=1&client=firefox-b&ei=HULRW4j6BILGwQLx4J9Q&q=polyester+resin+unlike+epoxy&oq=polyester+resin+unlike+epoxy
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?
Ok , let me do the math: 50 pieces cost $12, according to the link you provided. It delivers around 20W. If you'd like to power your house, you'd need 4000W, minimum. But let's say 2000W and special batteries, inverter and such electronics stuff. It will cost you $1200 , for the cells alone. It is not any cheaper at all. And then you buy additional stuff and adding all the work, it is more expensive. And... You wrote 'Make solar panels yourself' , which is not correct. You bought them. But oh well ... Many videos talk about DIY solar panels and do the same thing, so, ok.
You are right for the energy of the house it does not fit, but I did not say that for the house, there are other goals. For example, the energy to go to the mountains. As for the panels: I bought the cells and made the panels. Cell is an electronic element, the panel is a finished product.
You are right about that. An I do not intend to debunk your video; I do owe you a small apology. There are products on AliExpress that provide for, what you speak of for similar costs, however, customising this for your own needs is the aspect in this video that is very usefull. Besides, it is also the experience that counts. All in all: Great video. Thumbs up :)
You are absolutely right, in the vacuum chamber the bubbles quickly leave the resin and I have a vacuum chamber. But I made videos for ordinary people who do not have a vacuum chamber. In general, bubbles do not affect the operation of solar cells. :)
Nice video. But I will have to say that your solder connections you showed in the video were a bit cold and not secured all the way. Especially the anode side of the cell. Also, it'd be better if the wire for the anode was the full length of the open strip area.
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 🌷👍
Tip 1 super glue is (usually) designed to wick into gaps, hold the cell up with a flat toothpick and add a drop of glue into the corner gap, let it wick under, then remove the toothpick. tip 2 A hot air gun, hairdryer or the very very gentle application of a torch can clear bubbles out of thin films of epoxy.
Tip 2 has saved me many times. If epoxy is setting too fast, with bubbles still inside, heat will soften the epoxy and expand the bubbles right out. Works very well.
Can you make a solar panel from scratch like the ones used in solar garden lights. The ones like 1inch x 1 inch glass coat with the reflector material.I mean just the panel. What all materials needed etc. If not where can I purchase it?

Так как насчет того, чтоб утереть нос всем, и в замкнутом контуре , где холодильник внизу, а нагреватель сверху добиться циркуляции теплоносителя без подключения к электросети или аккумулятору 😎
А решение где-то рядом😁 в этом вашем видео между 1 и 2 минутой косвенное тому доказательство😊
Фотоэлемент это деталь, материал, а панель это готовое изделие, прибор. Также как лампочка и торшер.

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.

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!
You could clean the rosin off with acetone. (Nail polish remover!)
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.
@@grain-diose Ok, Thank you for the reply! ☺
You could add this information in the video
Few remarks, if I may. Since most epoxy is not UV-proof, I think you need a kind that is and that is for sale. Otherwise it turns to a bit to yellow/brown, and not shining anymore, after a while. Or protect it with a UV-coating.
Made a few myself, like you, about 20 years ago and they still work fine.
And why not use a vacuum to get the air out, in the cup with the epoxy?
A vacuum-cleaner will do the job. Spinning it while curing, could be an option, may be, Did not try that, may be for the next solar-cells.
And later on also, to get a better connection and underlaying, while curing. Takes some more epoxy, ok, but also more durability, in wheather things, like hail.
A form will spares a lot of time, I think and easier to combine more cells.
And please take care for the epoxy-allergy, so use gloves and a mask etc.
Epoxy ressin hardly shrinks and is very resistend, so good choice and thank you for this video.
Thanks for the tips! Yes, epoxy resin is also harmful, I forgot to write. About ultraviolet: the cells that I use give better current from heat rays - infrared radiation. I showed in some videos how well they work from the candle, from the match and from the incandescent lamp. And this video as my whole channel is not for serious home-made products for the home, it is entertainment products. However, from these solar cells, you can make a battery for travel. I connected 10 cells last summer and got a current of 0.4A on charging a smartphone - th-cam.com/video/WWKRbpPzECc/w-d-xo.htmlm10s
Frits, that wasn't epoxy resin, more likely polyester resin at 9 to 1 hardener. Epoxy is 50/50.
@@legallyinsane7151 it may well be polyester resin or similar, but
Epoxy is not only 50/50.
Have literally bought and used several ton in stone industry , and that is used variably at less than5% to no more than 10%
@@legallyinsane7151 also we use 3:1
congratulations brow!!!! nice work...everyone says do it, d't do that.... but you make it man... show...
the finished epoxy looked amazing!
Thanks a lot of interactive video, it's truly inspired. WATB🙏
Why poliester resin? and why not to spray it but apply it with toothpick? While you prepare the plastic support it is positive if you open canals for wires, that will help you stabilizing the wires easier.
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.
good music, work and edit thank you man:)
Hi would this work with a solar charge controller like u put an car battery and the charge controller would this work
Why not?
Cyanoacrylate is not harmful. It even being used in medical procedure where it often used to seal wound that cannot be stitched.
"Пары цианоакрилата, представляющие собой мономеры, могут раздражать слизистые оболочки глаз, носа и горла, но при достаточной концентрации они моментально полимеризуются под воздействием влаги и становятся инертными. Считается, что риск может быть незначительным, если работать в хорошо проветриваемом помещении. При регулярном взаимодействии с цианоакрилатом около 5 % людей испытывают симптомы, схожие с симптомами гриппа. Цианоакрилат также может раздражать кожный покров и вызывать аллергические кожные реакции. В редких случаях вдыхание паров может вызвать астму. Для разных цианоакрилатов токсичность может существенно отличаться."
Transfer:
"Cyanoacrylate vapors, which are monomers, can irritate the mucous membranes of the eyes, nose and throat, but with sufficient concentration they instantly polymerize under the influence of moisture and become inert. It is believed that the risk may be insignificant if working in a well-ventilated area. With regular interactions with cyanoacrylate, about 5% of people experience symptoms similar to flu symptoms. Cyanoacrylate can also irritate the skin and cause allergic skin reactions. In rare cases, inhalation of vapors can cause asthma. For different cyanoacrylates, toxicity may vary significantly."
"Октил-2-цианоакрилат - наименее ядовитый из цианоакрилатов - применяется в медицинских целях для склеивания ран и для остановки кровотечений."
Transfer:
"Octyl-2-cyanoacrylate - the least toxic of cyanoacrylates - is used for medicinal purposes to glue wounds and to stop bleeding."

Nice, but what happens when the resin doesn't hold to the U/V light that it should be getting obliterated by everyday?
This is a cover for small homemade products for short-term use. I did not carry out tests with ultraviolet light for a time.
Would Fiberglass Resin work?
Do you want to use fiberglass as a base? Why not, but is it convenient to make it and will it be or is it beautiful. Or I do not understand your question? Sorry, I do not know English well.
the resin is the coating over fiberglass matt its clear and a type of epoxy that hardens
@@kimmccarl1089 I don't know if fiberglass resin is clear over time.
Yes, I believe he thought you meant as a base.
So HAPPY you are using Metric! Fantastic. Is so bloody annoying with US still using backward imperial
never saw this many bubbles in epoxy, and your quality too if you just tilt your mix you get better result. next problem is epoxy turn orange after long UV radiation.
Try stirring the epoxy for 30 minutes and you will see bubbles. In order for the resin to have no divorce after curing and to look beautiful, long stirring is required. As for UV radiation, you may be right, but my method is not intended for the roof of the house and providing it with energy, it is simply unprofitable and troublesome. I make such panels for my experiments. But you can use this method for example to make a panel of 10 cells and charge your phone during a picnic. This will give 5 Volts and 400 mA, see here - th-cam.com/video/WWKRbpPzECc/w-d-xo.html
@@grain-diose not bad yeah 2W, i mix my epoxy about 2 min and it works too (iam very carefull while mixing, bubbles dont really disappear while let it sit). i like that you are not offended rather you give an solid answer. i would use polyurethane lacquer transparent for this panels
Actually, don't worry about vigorously mixing the epoxy at all, and some might recommend a heat gun or torch. Don't do either, mix well and just use a fine mist spray bottle with some 70% or higher Isopropyl alcohol.. spray it on and watch all the thousands of micro bubbles, even the ones you can't see just disappear.. it's very satisfying and a cheap but awesome solution. I wouldn't use a heat gun/torch, because introducing heat can make the epoxy set quicker, too much can actually warp the epoxy unevenly aka burning it, and again too much heat could damage the cell. Best!
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?
Perhaps I have not tried.
Why must you use 24hr curing epoxy as opposed to faster cure?
You can use a faster one, but I think the coating layer will not be so even.
However, this is only a criterion of aesthetics, it does not affect the quality of work.
@@grain-diose Feasible theory.
I wrote in the video, but I will repeat: an epoxy glue is needed that hardens in 24 hours. 15-minute, 30-minute and other fast adhesives are not suitable for this. You can try a quick epoxy glue, but I do not know what you get.
Sir please tell me the principle of your mendocino motor🙏🙏🙏 please ....
3 solar cells with 3 coils are connected in a circle. Light must go on one side more. On this side, one of the cells gives more current and turns the rotor thanks to static magnets. 2 other coils act as conductors. Then another cell with another coil becomes this place, now it gives more current and turns the rotor on.

What you get with a faster setting epoxy is a faster yellowing/degrading result. Even the 24 hour epoxy will degrade but it will take longer.
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.
I want arrange for my Air Conditioner of 1.5 ton, how many this plates needed?
50 cells is 10 watts - th-cam.com/video/WWKRbpPzECc/w-d-xo.html
How long did it take you?
In such a situation, it is better to go to work after hours and buy a new solar panel.
I don't think the most integral part of the panel is the epoxy glue..."how to make solar panel with solar cells" would be a better title.
Merci beaucoup. S'il vous plait combien de paneau. on a besoin pour avoir 48 wathed , voltamètre
Gfd
And what can you use a 0.5 volt solarpanel for?
I use for experiments, you can solder on one plate how many cells you need. I wrote about this at the end of the video.
PM, dude, you wire them in series.
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.
It is also simple. You should stick several cells on one plastic and solder them together. Then you cover everything with epoxy.
Is it necessaru to use russian epoxy glue?
Necessary
@@JimmyBaevsky Not at all. Any epoxy resin is useful, but preferably with a long curing time so that the resin has time to level before polymerization.
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.
Thank you for this video! You helped me a lot:D

How does the epoxy and plastic hold up under sun UV? Most will break down into a powder over several months.
Maybe. But these panels are not made for use on the roof of the house, especially this method is labor-intensive for such a case. I make these panels for my experiments. You can use this method to make a hiking panel for charging your smartphone by connecting 10-12 cells on one plastic.
Can add wax, can long last 20 years under sun. Solid like cement.
No wax won't help as UV would go through it. UV light breaks down plastics polymers and many other compounds. Ever put for example a polyurethane in the sun? It turns to dust in 6 months. They do make UV additives for plastic and epoxy that slow down degrading like used in cars for example. Best to go with a UV rated epoxy.
Bhai choota solar kahase laya mujebhi kharidna he
All links are in the video description.
I'm wondering what I am missing here. I did a quick cost calculation per watt, and just the raw solar panels (before all the other parts and labor) come out to about twice what a decent, pre-built solar panel costs. In other words, unless I'm missing something, it's cheaper to buy pre-built solar panels and save yourself all this work.
Not only the labor involved, time is money. Who would really want to spend a year's time building something that is on the market ready to go?
What is the Ampere rating for each cell? Video have voltage rating shown but not have Ampere rating mentioned... Please reply sir! I'm willing to buy those... And it's so important for me...please reply with Ampere rating...& how much Watt(if possible)...!
In the sun, these cells have 400 mA, see here - th-cam.com/video/WWKRbpPzECc/w-d-xo.html
Great Video thanks , can I incorporate the same method to make big solar panels? Did you make any video for that?
Thanks
resin becomes more pliable if you apply a little heat also you can get rid of the bubbles with a little heat you can also get a bubble release spray
what is the anode and cathode material? what is the blue color, and how did apply it?
Don't you lose too much power from the damages you inflict to the cell (soldering and glue seems to alter quite a zone around) ?
I did not notice any changes.
LeChat, do you see an alternative?
Who else came to the comments section to see if it works?😂
Me
Good job good idea love you from PAKISTAN
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. 👍
Where can I buy the epoxy glue that you use in this video?
I think only in Russia. I brought it from Moscow. But epoxy glue is used all over the world and can be found in hardware stores. You can also find it in aircraft model clubs, epoxy with fiberglass is used to make composite materials. Other polyester resins that can be better than epoxy to coat panels also exist and are used in different areas. Industrial solar panels are made with this resin, not epoxy.
See Google for more details - www.google.com/search?newwindow=1&client=firefox-b&ei=HULRW4j6BILGwQLx4J9Q&q=polyester+resin+unlike+epoxy&oq=polyester+resin+unlike+epoxy
where do I apply it and can I remove the contactor? do home computers and smartphones work?

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?
Ok , let me do the math: 50 pieces cost $12, according to the link you provided.
It delivers around 20W. If you'd like to power your house, you'd need 4000W, minimum.
But let's say 2000W and special batteries, inverter and such electronics stuff.
It will cost you $1200 , for the cells alone. It is not any cheaper at all.
And then you buy additional stuff and adding all the work, it is more expensive.
And... You wrote 'Make solar panels yourself' , which is not correct.
You bought them. But oh well ...
Many videos talk about DIY solar panels and do the same thing, so, ok.
You are right for the energy of the house it does not fit, but I did not say that for the house, there are other goals. For example, the energy to go to the mountains. As for the panels: I bought the cells and made the panels. Cell is an electronic element, the panel is a finished product.
You are right about that.
An I do not intend to debunk your video; I do owe you a small apology.
There are products on AliExpress that provide for, what you speak of
for similar costs, however, customising this for your own needs
is the aspect in this video that is very usefull.
Besides, it is also the experience that counts.
All in all: Great video. Thumbs up :)
Thanks!
For cutting the long strips into shorter squares, a paper cutting board would help drastically. It comes already with a measuring scale on it.
These are details of the personal taste of each master. :)
This is true :)
You should put it on the vacuum chamber if you had one because it suck some air bubble on epoxy resin i don't know if that work
You are absolutely right, in the vacuum chamber the bubbles quickly leave the resin and I have a vacuum chamber. But I made videos for ordinary people who do not have a vacuum chamber. In general, bubbles do not affect the operation of solar cells. :)
I really like your idea, but I wonder adding the cost of the plastic substrate and epoxy and labor if is cost effective?
Nice! Can i use fiberglass resin to cover cells? what size of wires did you use?
You can make any coating if it is transparent enough.
Why are you using the epoxy, to make it waterproof? Or is there some other reasons? Please explain...
Tahank you for inspiration Grain
Hello, how do you solve the phenomenon of epoxy resin softening when heated
Nice and careful video. Very explanatory notes! Thnx!!
Nice video. But I will have to say that your solder connections you showed in the video were a bit cold and not secured all the way. Especially the anode side of the cell. Also, it'd be better if the wire for the anode was the full length of the open strip area.
Perhaps you are right, thanks for the criticism.
Where did you purchase that white plastic from? Link please? Thanks
I bought at a hardware store.
buen vídeo excelente trabajo esta muy interesante saludos y gracias
Enjoyed and subscribed,
Greetings from Minnesota U.S.A. :D
Thank you! Greetings from Moldova!
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 🌷👍
Tip 1
super glue is (usually) designed to wick into gaps, hold the cell up with a flat toothpick and add a drop of glue into the corner gap, let it wick under, then remove the toothpick.
tip 2
A hot air gun, hairdryer or the very very gentle application of a torch can clear bubbles out of thin films of epoxy.
Tip 1 - yes
Tip 2 - this may cause the resin to cure quickly.
Tip 2 has saved me many times. If epoxy is setting too fast, with bubbles still inside, heat will soften the epoxy and expand the bubbles right out. Works very well.
I would love to try your cost cutting idea
Very good video!. Thank you!.
