Do you know a cheap instructable for solar cells? Tips/ideas Answered
Do you know where I can find a cheap how to for solar cells? The ones I've found cost around $200 and more but I cant be spending money on materials for a how to that might not even work. For materials around the house I have aluminum cans, copper wire, hot glue....you get the idea. If you have tips where to go to find an how to that I can afford, or tips on how to make a solar cell out of aluminum, please let me know.
