Solar street lights are powered by crystalline silicon solar cells, use maintenance-free valve-controlled sealed batteries (gel batteries) to store electrical energy, use ultra-bright LED lamps as light sources, and are controlled by intelligent charge and discharge controllers to ｒｅｐｌａｃｅ traditional public electric lighting street lights.

Advantages of Solar Street Lights

Solar energy is an inexhaustible, clean, pollution-free and renewable green energy. Solar power generation has advantages that other conventional energy sources do not have, such as incomparable cleanliness, high safety, relative extensiveness and sufficiency of energy, long life and maintenance-free. Photovoltaic energy is considered to be the most important new energy in the 21st century. Solar street lights do not require laying cables, AC power supply, and electricity bills; they use DC power supply and control; they have good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, and economical and practical advantages. They can be widely used in urban main and secondary roads, communities, factories, tourist attractions, parking lots and other places.

Solar street light components

The solar street light system can ensure normal operation for more than 2-7 days in rainy weather! Its system consists of LED light source (including driver), solar panel, battery (including battery insulation box), solar street light controller, street light pole (including foundation) and auxiliary wires.

Working principle

Working principle of solar street light: During the day, solar street light is controlled by intelligent controller. Solar panels absorb solar light and convert it into electricity. During the day, solar cell modules charge the battery pack. At night, the battery pack provides power to the LED light source to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharge or over discharge. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

Solar street lights do not require laying underground cables or paying for lighting electricity. The key components of solar garden lights, solar panels, solar DC street light intelligent controllers, maintenance-free batteries, and lighting fixtures have all been certified by the National Development and Reform Commission/GEF/World Bank for photovoltaic products. It is mainly suitable for lighting in urban roads, community squares, industrial parks, tourist attractions, park green belts and other places.

Technical advantages of solar street lights

1. Easy installation: When installing solar street lights, there is no need to set up complex circuits. Just make a cement base, a battery pit, and fix it with galvanized bolts. It does not require a lot of manpower, material resources, and financial resources. The installation is simple, and there is no need to string wires or dig the ground for construction, and there is no worry about power outages or power restrictions.

2. Low investment: Solar street lights require only one investment and bring long-term benefits. Because of the simple circuit, there is no maintenance cost and no expensive electricity bill. The cost can be recovered in 6-7 years, and more than 1 million electricity and maintenance costs can be saved in 3-4 years. It can save the high electricity bills of city street lights, complex circuits, and the need for long-term uninterrupted circuit maintenance. Especially in the case of unstable voltage, it is inevitable that sodium lamps are easy to break, and with the extension of the years, the circuits are aging and the maintenance costs are increasing year by year.

3. Good safety performance: Solar street lights use 12-24V low voltage, stable voltage, reliable operation, no hidden safety hazards, and are ideal products for ecological communities and road administration departments. There will be no accidents such as electric shock and fire. The safety hazards of city street lights are great. People's living environment is constantly changing, and there are many hidden dangers in road reconstruction, landscape construction, abnormal power supply, and cross-construction of water and gas pipelines.

4. Energy saving and environmental protection: Solar energy photoelectric conversion provides inexhaustible electricity. No pollution, no noise, no radiation. Solar street lights can add new selling points to the development and promotion of high-end ecological communities; they can sustainably reduce property management costs and reduce the public share of owners. In summary, the inherent characteristics of solar lighting, such as safety, no hidden dangers, energy saving, no consumption, green environmental protection, easy installation, automatic control and maintenance-free, will directly bring obvious advantages to the sales of real estate and the construction of municipal projects.

5. Long life: The life of solar lamps is much longer than that of ordinary electric lamps. For example, the main component of solar lamps, the solar cell module, has a service life of 25 years; the average life of low-pressure sodium lamps is 18,000 hours; the average life of low-voltage high-efficiency tri-color energy-saving lamps is 6,000 hours; the average life of ultra-bright LEDs is more than 50,000 hours; the life of solar-specific batteries is 2-5 years for batteries below 38AH; 3-7 years for batteries between 38 and 150AH. The product has high technological content, and the control system and accessories are all international brands, intelligently designed, and reliable in quality. According to the regulations of the local Price Bureau of conventional communities that "a one-time fee of 6 yuan/㎡ for community street lamp maintenance is charged based on the pure residential building area", the initial investment of ordinary lamps is much higher than that of solar lamps.
