Electricity knowledge sharing：Classification of solar power projects

At present, the mainstream solar power plants in the world are divided into two categories, namely photovoltaic

power plants and solar thermal power plants.

Photovoltaic power plant refers to a photovoltaic power generation system that uses solar energy and uses special

materials such as crystalline silicon plates, inverters and other electronic components to form an internal power

generation system that is compatible with the power grid and transmits power to the power grid.

Photovoltaic power plants are usually divided into centralized power plants and distributed power plants.

Centralized power plants are large in scale, built in deserts areas, and send electricity to cities through

high-voltage transmission lines. Distributed power plants are mainly built on the surface of buildings in cities

to solve the power problems of users nearby, but they are small in scale.

The solar thermal power plant uses mirror reflection to collect solar heat energy, provides steam through a heat

exchange device, and combines the technology of traditional steam turbine generators to achieve the purpose of

generating electricity. This technology can store heat in a huge container through molten salt or water and other

media, and it can still drive the steam turbine to generate electricity at night, which is not possible for photovoltaic

power plants.
