In the face of the deteriorating ecological environment in today's world, the importance of protecting the environment and optimizing the allocation of resources has attracted widespread attention of the whole society. In order to better realize the overall picture of environmental resources, coordinated and sustainable development strategies, it is imperative to vigorously develop and utilize renewable energy and new energy. As a green energy, solar energy can effectively alleviate the situation of tight demand, and it has been widely used in my country.
About the working principle of solar power
A solar cell is a device that converts solar energy into electrical energy by utilizing the photoelectric effect of semiconductor materials. Sunlight illuminates the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region, and the electrons flow from the p region to the n region. After the circuit is turned on, a current is formed.
You can connect to the battery and use it yourself, you can use it while charging, enough for a day's use, or you can have another way, you can connect to the power grid, you can sell electricity to the country and get money
Photovoltaic power generation is used in many fields, farmland irrigation, animal husbandry, rural areas, etc., all can use the solar energy system to generate electricity, without the need to connect to the mains, eliminating this cumbersome step.
In many remote rural mountainous areas in our country, the power supply may not be very complete, and it is often impossible to carry out smoothly due to the lack of electricity in daily life. However, if these areas have sufficient sunshine conditions, the photovoltaic power generation system can be used to solve daily needs.
As well as some old residential areas, due to planning and design problems, there may also be overloaded operation and tripping, which has a great safety hazard, burning switches, wire lights, and high residential density, small space for reserved facilities for power supply, and remake circuits. It is very difficult, therefore, photovoltaic power generation is also a solution. There is no need to worry about the danger of resource exhaustion, it is clean, and it is not limited by the geographical distribution of resources. It can generate high-quality power nearby, and can spend less time and get more reliable work.
To sum up, as a clean, safe and renewable green energy and new energy, solar photovoltaic power generation will be widely used in various industries with the continuous research and development of our country, and will also become one of the conventional energy sources.
As a new energy high-tech enterprise, Beijing Zhongneng Company has been aware of the rise of solar energy early. Since 2009, it has stepped into the new energy industry, allowing more people to enjoy green new energy. In the future, it will increase production investment and increase production. Manufactures good products with good prices and good quality.
