I'm getting ready for winter with 4 new solar panels. I used pallets to mount them and ice& water for waterproofing. For $500, the power generation is about to more than double!
PS, I'm tagging earthship b/c the foundations of the structures are earth-rammed tires, and much of the inspiration for my 'build style', including Ferro-cement domes, comes from Mike Reynolds and Earthship Biotecture.
