Solar radiation and panel temperature sensor
The energy theoretically producible provides normalization with a settable parameter that takes into account the efficiency of the panels used and the rated power plant. It is powered by solar cell 5V 100 mA assisted by lithium battery for the night periods and if lack of sunshine.
