1. The prospect of solar power generation
The development of new energy and renewable clean energy is one of the five most decisive technical fields in the development of the world economy in the 21st century. The full development and utilization of solar energy is a sustainable energy strategic decision of governments around the world, among which solar power generation is the most affected. eye-catching. Vigorously develop market applications. Facing the urgent shortage of energy and the global financial crisis, many countries have formulated ambitious development plans to promote the development of photovoltaic technology and industry. The promulgation of renewable energy laws in various countries, the fast-growing photovoltaic roof plan, various tax relief and subsidy policies, and the gradually mature green power price have provided a good foundation for the development of the photovoltaic market.
2. Advantages of solar street lights
Street light is the most common thing in our daily life, it brings light to our night life. Now the beautiful street lights make the night of the city more colorful. However, street lamps are a large power consumer. Due to the long low-voltage transmission lines of street lamps, not only street lamps but also transmission lines consume a lot of power, especially suburban roads and expressways far away from power sources. Therefore, many suburban roads and expressways in our country have not installed street lights. In fact, the lack of street lights on suburban roads and expressways has brought many safety problems. At present, in Beijing, Shanghai, Dalian and other developed cities, solar street lighting systems are being vigorously promoted. The installation of solar lighting is easy: when installing solar lighting, there is no need to lay complicated lines, just make a cement base, and then fix it with anti-rust screws. Solar lighting fixtures do not require electricity bills: solar lighting fixtures are a one-time investment, without any maintenance costs, and benefit for a long time. There is no potential safety hazard for solar lighting: solar lighting is a low-voltage product, safe and reliable in operation.Solar lighting has inherent characteristics such as safety and no hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free, which directly bring obvious advantages to the construction of municipal engineering. Solar street light is an automatic control working system, as long as the working mode of the system is set, it will automatically work. Solar street lights are ideal road lighting fixtures. With the improvement of people’s lives and the continuous development of society, they will be widely used, so that the light given by the sun to the earth can illuminate human beings at night. Solar street lights can be said to integrate light and the surrounding beautiful environment into one, electricity, mechanical design, control and other technologies. In addition to focusing on its reasonable appearance and structure and coordination with the environment, it is also necessary to carry out meticulous and scientific The optimal design of the solar cell module, the capacity of the battery and the size of the load power are reasonably determined to ensure the stable and reliable operation of the system and achieve the best economic benefits.
As the core product of solar lighting, the production cost of photovoltaic cell components continues to decrease, it is the general trend to install solar lighting lamps on the most roads without electricity. As we all know, the Antarctic void, acid rain, El Niño, air pollution, water pollution, soil pollution, marine pollution and other environmental problems caused by the use of traditional (non-renewable) energy sources (generating C02, 502 and solid waste, etc.) have made the living environment of human beings endangered. huge challenge. Not only that, according to the speculation of world authoritative organizations and experts, coal, oil and natural gas, which are the main body of the current traditional energy structure, will be exhausted within a hundred years if they are mined at the current speed. Therefore, energy saving and environmental protection issues have become important issues that all countries in the world face together.
