FYI Basic Solar Kit from Costco
Seems like a good DIY deal with all you get. 4 100w polycrystalline panels, 2000w PSW inverter, and looks like a Xantrex Trace C35Amp controller. http://www.costco.com/.product.100111497.ht...

QUESTION--------for home use how big a battery bank should one have?
Recommended bank size is 6-10 days of your average daily energy draw multiplied by 2. Because you want the bank to be at least 50% full after 6-10 days of zero solar charging, ex. snowstorm or heavy rain.
This is - for homes. RV users rarely carry more than 4-5 days energy supply.
