Buying solar cells to make solar panels DIY
If you are looking at making your own solar panels, the first thing you need to look into is the solar cells. The solar cells are the heart and soul of your solar panels and your whole solar power system. They determine how much power you will be getting and how much surface area you will need to create this power. If you are working with a limited amount of surface area, look for higher effiency solar cells.
When buying solar cells, there are three common types of cells on the market. Multicrystalline, Polycrystalline and Monocrystalline. All three types of cells are pretty equal as far as the effieciency goes. Monocrystalline cells tend to be less brittle. If you noticed, the corners are not there to break off during shipping. Shipping is kind of a “gray area” in the solar cell market for nonrefundable brakage. So if you need 12 solar cells, maybe order 14 just in case. This will also help if you have never worked with solar cells, you very well might break some yourself.
When looking to purchase, make sure the math adds up with the cells you are looking at. When I say math, I mean watts, amps, volts. Use Ohm’s Law. Ohm’s Law is: amps = watts/volts, volts = watts/amps, watts = volts*amps. If the math does not add up, there is something that the seller is not telling you or doesn’t know.
To purchase solar cells you can try doing a search. I found major suppliers (10,000+ orders) and solar panel companies on major search engines, but not much for small-mid solar cell orders. You can try www.SolarPhotovoltaicCells.net for small to mid sized orders. Let’s hope that in the future we can all say ”green killed oil”.
