Solar energy has many uses and many functions in life. It is a kind of radiant energy, pollution-free and pollution-free.
1. Power generation: that is, directly convert solar energy into electrical energy, and store the electrical energy in a capacitor for use when needed.
Such as solar street lights, solar street lights are a kind of street lights that use solar energy to generate electricity without power supply. This kind of street lamp does not need power supply, no need to use wire, relatively economical, as long as it can be used normally in places with sufficient sunlight, because such products are widely concerned and liked by the public, not to mention that they do not pollute the environment, so This can become a green environmental protection product, and solar street lights can be used in parks, towns, and lawns. It can also be used in areas with small population density, inconvenient transportation, underdeveloped economy, lack of conventional fuels, and it is difficult to generate electricity with conventional energy, but rich in solar energy resources, to solve the household lighting problems of people in these areas.
2. Heating energy: the heat energy converted from solar energy into water, example: solar water heater.
Solar energy was used to heat water a long time ago, and now there are millions of solar installations around the world. The main components of the solar water heating system include collectors, storage devices and circulation pipelines. It mainly includes temperature difference control heat collecting circulation and floor heating pipeline circulation system. Solar water heating projects are increasingly used in residential buildings, villas, hotels, tourist scenic spots, science and technology parks, hospitals, schools, industrial factories, agricultural planting and breeding areas and other major fields.
Others such as electrical energy can be converted into various mechanical energy, thermal energy can be converted into electrical energy, and electrical energy can also be converted into thermal energy.
