Advantages of solar street lights

Street light is the most common thing in our daily life, it brings light to our nightlife. The beautiful street lights now decorate the night of the city colorfully. However, street lamps are a big power consumer. Due to the long low-voltage transmission lines of street lamps, not only do street lamps consume electricity, but also power consumption on transmission lines, especially on suburban highways and highways far away from power points. Therefore, many suburban roads and highways in our country are not equipped with street lights.

The absence of streetlights on suburban highways and expressways poses several safety concerns. At present, in developed cities such as Beijing, Shanghai, and Dalian, solar street lighting systems are being vigorously promoted.

Solar lighting is easy to install: when installing solar lighting, there is no need to lay complicated lines, just make a cement base and fix it with anti-rust screws. No electricity bill for solar lighting fixtures: Solar lighting fixtures are a one-time investment, without any maintenance cost, and benefit in the long run.

There is no hidden safety hazard in solar lighting: solar lamps are low-voltage products and operate safely and reliably. The inherent characteristics of solar lightings, such as safety without hidden dangers, energy saving and consumption, green environmental protection, easy installation, automatic control, and maintenance-free, directly bring obvious advantages to the construction of municipal engineering.

The solar street light is an automatically controlled working system, as long as the working mode of the system is set, it will work automatically. Solar street light is an ideal road lighting fixture. With the improvement of people’s lives and the continuous development of society, it will be widely used, so that the light given by the sun to the earth can illuminate human beings at night.

It can be said that solar street lights integrate light and the surrounding beautiful environment into one, electricity, mechanical design, control, and other technologies. In addition to focusing on the reasonable appearance and structure and coordination with the environment, they also need to be careful and scientific. Optimize the design, and reasonably determine the capacity of the solar cell components, the battery, and the load power to ensure that the system works stably and reliably, and can achieve the best economic benefits.

With the continuous reduction of the production cost of photovoltaic cell modules, the core product of solar lighting, the installation of solar lighting lamps on most non-electric roads has become the general trend.

As we all know, due to the use of traditional (non-renewable) energy (producing C02, 502 and solid waste, etc.), the Antarctic cavity, acid rain, El Niño, air pollution, water pollution, soil pollution, marine pollution, and other environmental problems have caused the living environment of human beings. huge challenge. Not only that, according to the world’s authoritative institutions and experts, coal, oil, natural gas, etc., which are the main body of the current traditional energy structure, will be exhausted within a hundred years if they continue to be mined at the current speed. Therefore, energy conservation and environmental protection issues have become important issues faced by all countries in the world.

 Briefly describe the content of solar lighting

The user’s usage requirements, such as lighting for several hours a day, require normal lighting on several cloudy and rainy days. According to the above conditions, we can design products suitable for the local area. We design solar street lights according to the actual conditions of local roads. Generally, the spacing of solar street lights is 30 meters, and the user can determine the number of lights according to the length and width of the road section where the solar street lights need to be installed.
