Energy = 250 Wp · 5 hours · 0.75 = 937.5 daily Watt − hours = 0.94 kWh per solar panel. The daily combiner box production is thus: 0.94 kW h · 480 panels = 451.2 kWh . We can set the energy price at a fixed average value of 0.1 USD per kW h. With a ground fault in the PV array connected the combiner box, the financial loss per day is ...
CNNs are quite powerful but without data, there is not much you can do. To generate the polygons corresponding to the location of the solar panels I used Google Earth Engine. It took me about 1.5 hours to demarcate solar panels from a 1 km² area, resulting in the not very impressive total of 124 polygons (not as many as I expected).
Scientists beam solar power to Earth from space for 1st ...
