Solar power also called solar cell and PV cell. (It is make with flat crystal of different electronic semiconductor materials, we need to connect PV cell and wrap it in the compononets so that far away the influnce of envionment, when the light get into the crystal, the electronic from light were separated by electric field then makes emf happens bewteen top and bottom of solar cell. Meanwhile if you connect the circuit ,the DC current will formation which save into the batteries though solid Conversion equipment change into AC for supply serionus load. So even night or rainy days the load can still work too.
