JDSOLAR solar street light working principle: During the daytime, the solar street light is controlled by the intelligent controller. The solar panel is irradiated by sunlight, absorbs solar light and converts it into electric energy. During the day, the solar battery module charges the battery pack, and at night, the battery pack provides power to the battery pack. The LED light source is powered to achieve the lighting function. The DC controller can ensure that the battery pack is not damaged by overcharging or overdischarging, and has the functions of light control, time control, temperature compensation, lightning protection and reverse polarity protection.

JDSOLAR solar street lights do not need to lay underground cables, no need to pay for lighting electricity. The key components of solar garden lights, solar panels, solar DC street light intelligent controllers, maintenance-free batteries, lighting fixtures have passed the National Development and Reform Commission / GEF / World Bank photovoltaic products Certification. It is mainly suitable for lighting lighting of urban roads, residential squares, industrial parks, tourist attractions, park green belts and other places.
JDSOLAR technology advantage
1. Easy installation: When installing solar street lights, do not need to install complicated wiring, only make a cement base, make a battery pit, and fix it with galvanized bolts. It does not need to consume a lot of manpower, material resources, financial resources, and the installation is simple. It does not need to be wired or "opened and smashed" to dig the ground construction, and there is no power outage and power limitation. .
2. Less investment: solar street lamps are invested once and benefited for a long time. Because the lines are simple, no maintenance costs are incurred and no expensive electricity costs are generated. 6-7 years to recover the cost, 3-4 years to save more than 1 million electricity and maintenance costs. The circuit lamp can be omitted, the electricity cost is high, the line is complicated, and the line needs to be repaired for a long time without interruption. In the case of particularly unstable voltage, the sodium lamp is prone to be inevitable, and as the age increases, the line aging and maintenance costs increase year by year.
3. Good safety performance: Due to the low voltage of 12-24V, the solar street lamp has stable voltage, reliable operation and no hidden dangers. It is an ideal product for the ecological community and the road administration department. There are no accidents such as electric shock or fire. The safety of circuit lights in the city is great. People's living environment is changing constantly. Road reconstruction, landscape engineering construction, power supply is not normal, and cross-construction of water gas pipelines brings many hidden dangers.
4. Energy saving and environmental protection: The solar energy photoelectric conversion provides electric energy, which is inexhaustible and inexhaustible. No pollution, no noise, no radiation. Solar street lights can add new selling points for the development and promotion of noble ecological communities; sustainable reduction of property management costs and reduction of the cost of the public share of the owners. In summary, the inherent characteristics of solar lighting safety without hidden dangers, energy saving and no consumption, green environmental protection, easy installation, automatic control and maintenance-free will directly bring obvious advantages for the sale of real estate and the construction of municipal engineering.
5. Long life: The life of solar lamps is much higher than that of ordinary electric lamps. For example, the main components of solar lamps---the life of solar modules is 25 years; the average life of low-pressure sodium lamps is 18,000 hours; The average life of basic energy-saving lamps is 6000 hours; the average life of super-bright LEDs is more than 50,000 hours; the life of solar-powered batteries is 2-5 years below 38AH; 3-7 years of 38-150AH. The product has high technology content, and the control system and accessories are international brands, intelligent design and reliable quality. According to the regulations of the local community according to the local price bureau "one-time residential street lamp maintenance fee of 6 yuan/m2 according to the pure residential building area", the initial investment of ordinary lamps is much higher than the initial investment of solar lamps. In short, the comprehensive comparison of the characteristics of solar lamps to save investment is quite obvious.
In the solar power supply system, the performance of the battery directly affects the overall cost of the system and the operation and service life. This product uses JDSOLAR and the Institute of Metal Research of the Chinese Academy of Sciences to jointly develop the latest energy storage type colloidal battery, with ordinary lead acid. Compared with the battery, it has the following outstanding features in design and manufacturing process:
The service life is extremely long, and the service life under normal conditions is five to ten years.
The use of suitable positive and negative alloy formula and active substance ratio makes the battery more suitable for the charging and discharging of the energy storage battery.
The design of the colloidal electrolyte effectively inhibits the derusting of the active material and the sulfation of the plate, thereby delaying the performance degradation of the battery during use. The battery's deep charge and discharge cycle life has been greatly improved. Choose the LED light source of the four generations of lighting products.
