IMSA AT ROAD AMERICA

I'm at the track again for another 4 day IMSA race. One of my jobs there is to get photos of "other" stuff going on around the track. In one of the campgrounds I came across this fella and his dog "Otto" and he had these 4 photovoltaic cell devices he used to charge his electric bicycle and all the other electrical devices he had. There is a series of storage batteries that he charges during the day and it produces enough electricity to run his whole show, including TV, radio, computer, phone and all other electrical devices. Each panel will produce 100 watts of energy for storage. First one I've seen like this in our campground.
