How solar energy is converted into mechanical energy

Solar energy cannot be directly converted into mechanical energy. It must undergo certain quantum transformations to convert part of it into mechanical energy. For example, solar panels convert solar energy into electrical energy. , and some of it is lost during the conversion process. It's solar energy. The most direct example is the solar substation. Businesses get electricity through the substation. So how does solar substation get electricity via solar panels? . Convert.

Solar energy is the source of most of the earth's energy, and the conversion form of solar energy is wind energy. New energies The large-scale use of solar energy will in the future be used to produce electricity. There are many ways to generate electricity from the sun. There are mainly two typesfollowing which have been put into practice.

1. Light-heat-electricity conversion. In other words, the thermal energy generated by solar radiation is used to produce electricity. Generally, a solar collector is used to convert the absorbed thermal energy into steam as the working fluid, and then the steam drives a turbine to drive a generator to produce electricity. The first process is light-to-heat conversion, and the second process is heat-to-electricity conversion.

2. Conversion of light into electricity. 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.

Photochemical conversion is the process of converting chemical energy into chemical energy due to chemical reactions caused by the absorption of lumina radiationux. Its basic forms include plant photosynthesis and photochemical reactions that use chemical changes in substances to store solar energy.

Plants rely on chlorophyll to convert light energy into chemical energy to achieve their own growth and reproduction. If the secret of photochemical conversion can be revealed, artificial chlorophyll can produce electricity. Solar photochemical conversion is the subject of active exploration and research.

The process of converting solar energy into biomass is carried out through plant photosynthesis. Giant algae.
