A class solar panel
Solar array is the power plant to transfer direct current from the solar into direct current energy. According to end users' requirement of power wattage and voltage, the solar panel can be applied assingle use, or as a combination of series (to satisfy voltage requiremnt) and paralll (to satisfy current requirement).
The sillicon solar modules have high efficiency, long lifespan and high reliability. It normall has 25 years lifespan.
