A couple of exta points.
When I set out convert my home to self generated power I searched the internet for sources. I opted for Earth for Energy a guide book that can be found at www.getearth4energy.com. There are a couple of things you should know about the book. The under $200.00 power package advertised will not be enough to get you totally on your own power. You can expand on you original project until you are generating enough power for your home. Also, and most important is that you should not try to disconnect from the power companies lines by yourself. Hire an electrical contractor to do the job so you will not injure yourself or anyone else in the process.
