You don't need a DIY solar panel system kit to go 100% solar power. After two years of work today I threw the switch and went 100% off grid with solar power. It really works! What is surprising is it cost less and was easier to do than expected. That being said I had a lot of help from Al http://YouTube.com/EcoNewPower. I will break down all the components the reason behind why I bought these items, the cost, wiring and how I installed the system. As of right now, if the power goes off today, we'll have lights tonight.
