PV on-grid Power system
The solar energy grid system’s design capacity range from a few kilowatts to hundreds of kilowatts, even megawatts and on the condition that the combination of domestic photo-voltaic (PV) with architectural are various, so the optimal designing of equipment’s selection should be based on the actual situation of pv array installation ( such as component specifications, orientation), can be roughly divided by centralized power supply and distributed power supply.
