So whats the deal with solar panels? How much do you end up paying per average watt-hour your house consumes through solar panels to equal your use? As in... if a panel costs $2000 for that generates 200Wh, im paying $20/Wh for the panel to equalize it. What are some real world figures though? And how many panels do you need relative to your average kwh use in say, California? Also, is it worth it and what are the tax incentives like?
