What are the functions of solar energy?

Solar thermal power generation: It mainly gathers the sun's energy together and heats it to drive a steam turbine to generate electricity.

Solar photovoltaic power generation: Solar cells are combined together in any size and scale. It can be used for independent power generation or grid-connected power generation.

Solar water pump: It is replacing the solar thermal power water pump, and the 2 5kw photovoltaic water pump developed by China in the nineties is used in Xinjiang.

Solar water heater: Since the first water heater was developed in 1958, after more than 40 years of efforts, the production and sales of solar water heaters in China have ranked first in the world.

Solar buildings: There are three forms of solar buildings, namely passive type: simple structure, low cost, and natural heat exchange to obtain energy; Active:

The structure is more complex, the cost is higher, and electricity is needed as auxiliary energy; "Zero-energy building": the structure is complex, the cost is high, and the energy required for all the buildings is provided by the "solar roof".

Solar drying: After the 70s of the last century, solar dryers developed rapidly, especially in rural areas, and solar drying experiments were carried out on many agricultural and sideline products.

Solar cooker: Solar cooker can be divided into two categories: hot box type and concentrating type, and China is the country with the most popular application of solar cooker in the world.

Solar refrigeration and air conditioning: It is an energy-saving green air conditioner, no noise, no pollution, and can be put into commercial production quickly.

Other uses of solar energy: it can desalinate seawater, use sunlight to catalyze the environment, cultivate energy plants, and have a wide range of applications in communications, transportation, agriculture, disaster prevention, cathodic protection, consumption, electronic products and many other aspects.

What are the uses of solar energy?

Is it a water heater, or is it a solar power ......?

Because the sun brings light and heat to everything on earth. Without sunlight, there would be no animals, plants, microorganisms, and all life activities on the earth, including human beings. Without the sun, photovoltaic, wind power, tidal power on Earth would not be able to be manufactured.

Without the sun, there would be nothing on earth.

In order to survive, human beings must find new alternative energy sources, and solar energy is inexhaustible, and the life span of the sun is estimated by scientists to be hundreds of millions of years, so there is plenty of time to find new energy sources that can meet the needs of survival.

The function of the sun

The sun does not produce spring blind exhaust gases, and can be ...... with solar energy, solar cars, and solar watchesThese save electricity, water, and the environment.

Sunlight shining on ** will dilate the subcutaneous blood vessels, increase blood flow, increase the excretion and resistance of toxic substances, and the nuclear branch will also increase the secretion of saliva and gastric juice, strengthen gastrointestinal peristalsis, and promote appetite and digestion.

**It can also produce vitamin D from some chemicals, such as ergosol and cholesterol, when exposed to sunlight. This vitamin, calcium and phosphorus, which are important components of bones, can lead to cartilage sensitization.
