I did a search here on "Solar Power" and got a lot of...well, nothing. And I can't seem to find websites of informational value as well. What I would like to start with is a simple 500w systen to run a few simple things. But I have questions...*sigh* Can panels be added onto existing panels later for more power? I'm having trouble with batteries. If I want a 120v system to run, say a small refrigerator, I know I have to have an inverter. But because a fridge doesn't run all the time, I haven't a clue as to: What type of batteries? How many batteries? Which are the best batteries? And I simply cannot afford $200 golf cart deep cycles. So what to do? The same questions can be asked if I wanted to run a small window a/c unit for a single bedroom at night. Are the Federal incentives a one time only deal and whole house or can I get an additional incentive a year later when I add another one or two panels? It's all somewhat mindboggling to me at this time. I need help from those that have installed small solar power systems. Thanks for any help. eta: It's been said solar is affordable. A 260w system (two 130w panels) with modules is $1200.00. I can't see that as affordable....to me at least.
