Build a Solar Power Generator for Under $300
Just a quick article on a very basic solar setup. Note, a $100 solar panel won't really produce much power, it looks like the highest wattage panel I can get on ebay is 40-50W. Enough to perhaps power a few CFL lights at night.

Even a little $25 PV can charge up an old car battery..
But, 5 or 10 watts might not be sufficient to charge up a battery in a low SOC (like one that was used nightly). If you wanted to run some CFLs every night, I would shoot for the highest PV power I could get. 50 to 100 watts might be good. Depending on how much stuff you wanted to plug in at night.. My rough guesstimate: If you wanted 50w for 5 hours each night, then you may need about 100w of PV charging the battery for 5 hours each day.. |

All my panels came from Ebay, via China.
DM solar sells some nice looking PV. 120w solar panel, solar module 120w But, be sure to check the bottom line "** Minimum Order Quantity: 2" Some of them only sell in lots of 20.. |
