According to the market price in 2019, the price of one square meter is about 600 yuan.
The solar photovoltaic system is a facility that converts solar energy into DC energy by using the photovoltaic effect of photovoltaic semiconductor materials. The core of photovoltaic facilities is solar panels.
Semiconductor materials used for power generation mainly include monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. In recent years, all countries are actively promoting the application of renewable energy, and the photovoltaic industry has developed very rapidly.
Extended data:
As of 2010, solar photovoltaic has been put into use in hundreds of countries around the world. Although its power generation capacity still accounts for only a small part of the total human electricity consumption, since 2004, the photovoltaic power generation connected to the power grid has increased at an average annual rate of 60%.
By 2009, the total power generation capacity has reached 21gw, which is the fastest growing energy at present. It is estimated that the photovoltaic system without connection to the power grid also has a capacity of about 3 to 4gw.
The photovoltaic system can be installed on the ground on a large scale to become a photovoltaic power station, or it can be placed on the roof or outer wall of the building to form the integration of photovoltaic buildings.
