Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation.
A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It consists of thin solid photovoltaic cells almost entirely made of semiconductor materials (such as silicon). Since there are no moving parts, it can be operated for a long time without causing any wear.
Simple photovoltaic cells can power watches and calculators, while more complex photovoltaic systems can light a house and power the grid. Photovoltaic panel assemblies can be made in different shapes, and the assemblies can be connected to generate more electricity.
Photovoltaic panel components are used on rooftops and building surfaces, and even as part of windows, skylights or shading devices. These photovoltaic installations are often referred to as building-attached photovoltaic systems.
