Difference Between Online UPS and Offline UPS – Which One is Better? What is UPS (Uninterruptible Power Supply)? UPS is an abbreviation for Uninterruptible Power Supply and the reason for its name is that it provides a constant supply of power without any interruption. In Normal operation, it draws current from the AC mains and during a power outage; it draws current […]
Independent photovoltaic power generation Independent photovoltaic power generation is also called off-grid photovoltaic power generation. It is mainly composed of solar cell components, controllers, and batteries. To supply power to the AC load, an AC inverter needs to be configured. Independent photovoltaic power stations include village power supply systems in remote areas, solar household power

Reason 1: There is dust and obstructions on the surface of photovoltaic modules 1. Cause Analysis Dust accumulates on the surface of the photovoltaic panel, which reduces the light transmittance of the photovoltaic glass surface and the output performance of the photovoltaic panel. The thicker the dust concentration, the lower the light transmittance, the lower the solar
