I'm looking for the same simple power cures.
I purchased a Go Power! GP-PSK-120 120W Portable Folding Solar Kit.
I have been creating loads for the solar to recharge in the driveway, being I have to work. I ran 2 fantastic fans for 2 days and the power was down to 40% with cloudy skies on the second day. That afternoon, when I saw that the power was that low, I turned off the fans. The solar with cloudy skies brought the power up to 80% before dark.
I just have the panel sitting flat on the roof. That's not bad for $600.00 including an extra extension cord.
Tomorrow it will 100% the battery without the fans running with clouds.
