Solar energy is a renewable energy source that refers to the energy obtained from solar radiation. Solar energy can be converted into electricity or heat to meet human energy needs. The solar panel is a device that converts solar radiation directly into electrical energy, and it is composed of multiple solar cells.

Solar thermal energy harvesting systems convert solar radiation into heat, which is usually used to heat water or houses. Compared with traditional fossil fuels, solar energy is very polluting and is a renewable energy source, so the future development is promising. However, at present, the cost of solar energy is still high, and it is necessary to continuously improve the technology and reduce the cost in order to widely promote the use of Dashouxiang.

Solar power generation: Solar energy is stored together and cooled to drive a steam turbine to generate electricity. Solar water heaters.

Converts solar energy into heat and water from low temperature to high temperature. Solar cooker: It is mainly divided into two types: hot box type and concentrating type, which can save gas resources. Solar water pump: In remote areas where electricity is scarce, solar water pump water supply is an ideal green energy system.

1. Use solar power generation: Solar energy is accumulated together and cooled to drive the steam turbine to generate electricity.

2. Solar water heater: converts solar energy into heat energy, and changes water from low temperature cooling to high temperature.

3. Solar cooker: It is mainly divided into two types: hot box type and concentrating type, which can save gas resources.

4. Solar water pump: In remote areas where there is no electricity, solar water pump is an ideal green energy system integrating economy, reliability and environmental benefits.

5. Solar heater air conditioner: It is an energy-saving and environmentally friendly green air conditioner.

6. Solar photovoltaic power generation.

It can be grouped together, and the scale can be changed at will, and the application range is wider.

The utilization of solar energy is mainly reflected in solar thermal utilization, power generation, photochemical utilization and fuel utilization. 1、

Photothermal utilization. Solar radiation energy is harvested and converted into heat energy by interacting with matter for utilization. At present, the most widely used solar collectors mainly include flat plate collectors, vacuum tube collectors, ceramic solar collectors and focused collectors.

2. The use of solar power is widely used in solar street lamps, solar insecticidal lamps, solar portable systems, solar mobile power sources, solar energy application products, communication power supplies, solar lamps, solar buildings and other fields. 3. Photochemical utilization: This is a photochemical conversion method that uses solar radiation energy to directly decompose water to produce hydrogen. It includes photosynthesis, photoelectrochemistry, photochemistry, and photodegradation.

Photochemical conversion is the process of converting chemical energy into chemical energy due to a chemical reaction caused by the absorption of light radiation. Its basic form is photosynthesis in plants and photochemical reactions that store solar energy through chemical changes in matter. 4. Fuel oil uses the high-temperature energy generated by the concentrated rays of the sun, supplemented by metal oxide material additives, to convert water and carbon dioxide into syngas in the self-designed and developed solar high-temperature reactor.

High-temperature syngas generated from waste heat is converted into "solar" fuel products that can be commercialized in the market.

The benefits of solar energy are renewable, environmentally friendly and pollution-free.

1. Renewability

Solar energy is a renewable energy source, and the ** of sunlight is endless. Compared to the limited amount of fossil fuels such as coal, oil and gas, solar energy has unlimited potential. The photovoltaic power generation system can use solar energy to convert into electricity, thereby reducing the dependence on traditional energy sources and achieving sustainable energy development.

2. Environmental protection and pollution-free

There are almost no pollutant emissions from the solar power generation process. Compared to greenhouse gases such as carbon dioxide and air and water pollution from burning fossil fuels, solar power is a clean, environmentally friendly energy option. It has less negative impact on the environment and is effective in reducing greenhouse gas emissions, improving air quality and protecting ecosystems.

Disadvantages of solar energy

1. Instability: Due to the limitations of natural conditions such as day and night, season, geographical latitude and altitude, as well as the influence of random factors such as sunshine, cloud, cloud, rain, etc., the solar irradiance reaching a certain ground is both intermittent and extremely unstable, which increases the difficulty of large-scale application of solar energy.

In order to make solar energy a continuous and stable energy source, and thus eventually become an alternative energy source that can compete with conventional energy, it is necessary to solve the problem of energy storage, that is, to store the solar radiation energy in the clear day as much as possible for use at night or on rainy days, but at present, energy storage is also one of the weaker links in the utilization of solar energy.

2. Low efficiency and high cost: At the current development level of solar energy utilization, some aspects are theoretically feasible and technically mature. However, some solar energy is used to install compass, because of the low efficiency, high cost, in general, the economy can not compete with conventional energy.

For a considerable period of time in the future, the further development of solar energy utilization will be mainly constrained by economic constraints.
