I hope this is the best area to ask this... I want to learn how to build my own small solar panels. I seem to recall running across a plan to do so in a magazine a few years ago, but cannot for the life of me remember where I read it. Does anyone know how to do this? I'm wanting to build something that, at the least, could possibly run a small water heater. I know that there are numerous products out there for ready made solar heaters, but I would rather make my own and save $$$$. Thanks!
