Solar street lights are the basic equipment for the application of solar energy. With the development of economy and the rise of people's awareness of environmental protection, the development and utilization of solar energy has been deeply rooted in people. The popularity of solar street lights has risen linearly. The popularity of solar street lights will usher in a new climax. This situation is particularly obvious in my country: various types of solar energy equipment production enterprises are continuously established, the government promotes electrical transformation, and the subsidies for the use of solar energy equipment are increasing.

So, why is there such a situation, and what are the advantages of solar street lights to win the recognition of others?
First of all. The application of solar street lights has brought great convenience and environmental protection to human life.
For better construction of the city, the street lamps in the city are generally changed to solar street lamps, and the prices of solar street lamps are reasonable. The traditional street lamp installation procedures are relatively complicated, and it is necessary to lay circuits, etc., and the power consumption is relatively high, and a street lamp base with a relatively large wattage is used. The price of solar street lights is relatively low, energy saving and environmental protection, and the installation procedures are simpler than traditional ones, and there is no need to lay very complicated circuits.
The price of solar street lamps is uneven, and the price is between two hundred yuan and one thousand yuan. Compared with traditional street lamps, the price is much cheaper. The reason for the inconsistency of street lamp prices is not only the different materials, but also the different brands chosen. For consumers, the brand is also a guarantee of quality.
Second, the working principle of solar street lights
Solar street lights convert solar energy into electrical energy to achieve lighting. On the top of the street lights are solar panels, also known as photovoltaic modules. During the daytime, these polycrystalline silicon photovoltaic modules convert solar energy into electrical energy and store them in batteries, so that the solar street lights are in the intelligent controller. Under the control, the solar cell panel is irradiated by sunlight, absorbs the solar light and converts it into electrical energy, and the solar cell module charges the battery pack during the day. In the evening, the electric energy is transmitted to the light source through the control of the controller, which illuminates people at night. At night, the battery pack provides power to the LED light source to realize the lighting function. Since solar street lights generate electricity through solar energy, there is no cable and no leakage or other accidents will occur. The DC controller can ensure that the battery pack is not damaged due to overcharge or overdischarge, and also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection. No need to lay cables, no AC power supply, no electricity charges.

Again, the advantages of solar street lights
1. Wide energy
Solar street lights use solar photovoltaic cells to provide electrical energy. Solar energy, as a new green and environmentally friendly energy source, is "inexhaustible and inexhaustible." Making full use of solar energy resources has a positive significance for alleviating the tension of conventional energy.
2. Simple and convenient installation
The installation of solar street lights is simple and convenient. There is no need to do a lot of basic projects such as laying cables like ordinary street lights. Only a base is needed to fix it. All the lines and control parts are placed in the light frame to form a whole.
3. Low maintenance cost
The solar power supply used by solar street lights, except for the conversion of the mains power supply to the city power supply on a rainy day, will have a small part of the electricity cost, and the operating cost is almost zero. The operation of the entire system is controlled automatically, without human intervention, and almost no maintenance costs.
In general, the status quo of solar street lights has its own characteristics, but also needs of the times and real development. I believe that with the continuous breakthroughs in technology, new technologies and new concepts will change the status quo of the use of solar energy, and promote economic development and daily life more clean and efficient.
