We visited a couple with an off-grid cabin. In winter, they had tried tilting their PV and solar heat collectors vertical to catch the sun off of the snow.

The result was that the PV made electricity, but the water did not get hot. Apparently a metallic reflector is required to transfer solar heat, painted wood/cardboard or snow doesn't cut it. But they do reflect electricity-producing light. At another cabin we visited, the owner said her TriMetric was recording a trickle charge reflected off of a full moon!

It seems to me that there was an article at Mother Earth News where they explored the results of doing that. Should be able to wade thru the online archives to find it. If my memory is correct (scary thought), it really boosted the PV output.

I'm not a member either (used to be, but that was when I had little 1 acre raised wide row gardens, had chickens and pigs.. NO MORE!!!!). I generally search the 40 years on CDs that I have.

Re: Solar Paneled Sides

Thanks Smitty and all others for your great input. I followed your bus building chronicles Smitty and was blown away. I only wish I had your skills. Thanks for posting so many great pictures then and now.

I also was interested in putting mirrors or other reflective material under/around the solar collector/heater and PV but was concerned about possibly starting a fire on a branch nearby if the sun is positioned just right.

Somebody is selling 1 KW solar kits for around $500 on ebay. He's (Lowcostsolar2010) got some real cheap solar panels too. I don't know anything about their quality. http://cgi.ebay.com/1kw-DIY-solar-cell- ... 230ae6bee7
