Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a power generation system that utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two types of independent operation and grid-connected operation. Way. Photovoltaics are divided into two categories, one is centralized, such as the large-scale northwest ground photovoltaic power generation system; the other is distributed, such as residential rooftop photovoltaic power generation systems.

A photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells that are almost entirely made of semiconductor materials (such as silicon). Since there are no moving parts, it can be operated for a long time without any wear and tear.

Specific introduction to photovoltaics

Photovoltaics is defined as the direct conversion of ray energy. In practical applications, it usually refers to the conversion of solar energy into electrical energy, that is, solar photovoltaics. It is mainly implemented by using solar panels made of semiconductor materials such as silicon to generate direct current using light, such as solar cells that can be seen everywhere in our daily lives.

Photovoltaic technology has many advantages: for example, it does not have any mechanical moving parts; it does not require any other "fuel" except sunlight, and it can work under direct sunlight and oblique sunlight; and it depends on the choice of site. It is also very convenient and flexible, and can be used on rooftops and open spaces in cities.
