Youre saving money: The system installation is expensive up front, but the reduced cost of energy makes the switch worthwhile over the long haul. Once your solar system is installed, SCE's net energy meter measures any excess solar energy you generate, sends it back onto the grid and credits your bill. Solar panels can be made from either monocrystalline or polycrystalline cells monocrystalline cells are more efficient and able to generate more electricity than polycrystalline cells, while polycrystalline solar panels are much more affordable. Photovoltaic cells are what make up solar panels, and they are responsible for converting sunlight into electrical energy. The new proposal is markedly different from the plan released last December. This is simply the per day numbers weighted by the number of days in the month. That means the total average cost of the system would come out to about $18,000.
