Where can I find good instructions to build a cheap solar panel on my own?
Building solar panels is not really a do it yourself kind of job. They are made in high tech factorys with specialized equipment and experianced engineers. It would probably be cheaper and easier to just buy some panels rather than try to make your own.
Lowe's has some good plans, i built one using a 4'x8' sheet of foam in a box 6 tall cut grooves in the foam paint it with Black latex paint put a inlet and outlet at opposite ends of the box 4 in dia cover the box with a clear sheet of plastic put a screen over the hole in the top a duct in the bottom with a fan hooked to a temp switch , [hint a fan limit switch out of an old furnace works ] run the fan duct in to the house
To build an effective but cheap solar panel, you need some expert advice. I recommend you get your hands on the comprehensive e-book and video instructions by Michael Harvey. His guide is very easy to follow and it will help you make a complete solar power system for less than $200. He also teaches how to make windmills. I hope this helps!
