I tried making my own panels once and had similar results. I ended up finding cheap panels on ebay here and there. I built a box on wheels with my all my inverters and controllers in it. I have a small post on it in my blog you'll have to check out. Wait till you want to power your neighborhood. lol I also have a guy in a town near me that converts solar into hydrogen and runs his car and heats his house with it. I'll follow you for sure!
