Description

Hunan Education Edition Sixth Grade Volume 1 Science, Utilization of Solar Energy PPT

Part One: Solar Power Generation

solar energy generation

The large-scale utilization of solar energy in the future will be used to generate electricity. There are many ways to generate electricity from the sun. There are mainly the following two types that are currently in use.

①Light-heat-electricity conversion. That is, the heat energy generated by solar radiation is used to generate electricity. Generally, a solar collector is used to convert the absorbed heat energy into steam as a working fluid, and then the steam drives a turbine to drive a generator to generate electricity. The former process is light-heat conversion, and the latter process is heat-electricity conversion.

②Light-to-electricity conversion. Its basic principle is to use the photovoltaic effect to directly convert solar radiation energy into electrical energy. Its basic device is a solar cell.

Modern solar thermal technology concentrates sunlight and uses its energy to produce hot water, steam and electricity. In addition to using appropriate technology to collect solar energy, buildings can also harness the sun's light and heat by incorporating appropriate features into their design, such as large south-facing windows or using building materials that absorb and slowly release the sun's heat. .
