I installed solar on my house about 3 years ago. It's something I had always wanted to do, had researched a lot and really ran the numbers. So after 3 years I have to say I'm even a bigger fan of it seeing the results. I installed a 10k system, which is the largest residential system you can recieve full credits for. My annual demand in an all electric house is about 7.5 KW a year. I've been producing on average about 12 KW a year. I added some more efficient fixtures and insulation. The goal was to be net zero, and ii've well surpassed that. the system will pay itself off during this year. I just don't understand why solar doesn't get more support in the US. It's running strong in europe. There is no doubt it works and the technology is only getting better. Not to mention the fact that the USA is missing out on a huge growth manufacturing market. The chinese now own the panel production, the germans the technology and inverters. We are really missing the boat. I have no more utilitiy bills. in fact i'm selling excess back to the grid.
