Solar cell temperature

Above: outdoor temperature, it was a very warm day. Below: the temperature of the solar cell after a minute on the sunshine! I'm sure this will be great when used to heat up the floor of the greenhouse! Solar cell does NOT produce electricity but will heat up the water which is circulating to the floor of the greenhouse. Therefore it's much more powerful than solar panel "toys". The warm floor will keep the heat over the night which is great for the plants. Warm floor and cool air combination seems to work best during the nighttime.
