How I built an electricity producing Solar Panel Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property.
Homemade Solar panels At the end, the solar absorber is painted black and placed in the diy solar panels casing.
