I have seen some questions and responses in this regards in this forum. I am not very convinced, so I shoot the question again. Is it possible to feed PV cells with LED lighting? With LED's coloured lighting is easier, and getting a frequency in the range rated for a panel is easier. But would we be producing more energy than what we supply for the LED panel? I am considering a model as follows; 1 PV panel open to sun. This would power my LED panels and temperature regulators(Not an AC but some fan setup). 1 or 2 PV panel working with the LED panels, inside a temperature regulated closed environment. Would this be an efficient design?
