Solar panels mainly absorb the sun rays as sources of energy for generating the electricity or heat. It is a combination of the multiple cells of solar category that are scientifically arranged for ensuring charge transfer, which results from the generation of the energy. The Solar panels are developed from second most element, like Silicon, which is abundant in nature.

Semiconductors offer it a property of metal and metal insulator. Two kinds of Silicon basically the p and n kind are utilized to develop the PN junction. Sunrays that comprise of photons strikes the cells and thereafter it charges the electros for moving and leaving the hole. The charged electrons then move ahead and the positively charged holes are filled with electrons. This is the time when charge flows and the process creates charge.
