What are the highlights of the working principle of solar street lamps?

The service life of solar lamps is much longer than that of ordinary electric lamps. For example, the service life of solar cell module, the main component of solar lamp, is 25 years. The average life of low-pressure sodium lamp is 18000 hours; The average life of low-voltage and high-efficiency tricolor energy-saving lamps is 6000 hours; The average life of ultra-bright LED is over 50,000 hours; The service life of special solar cells is below 38AH for 2-5 years; 050 in 38-65438+3-7. According to the local price bureau's stipulation that the street lamp maintenance fee is charged at one time in 6 yuan/㎡ according to the pure residential construction area, the initial investment of ordinary lamps is much higher than that of solar lamps. In a word, by comprehensive comparison, the characteristics of saving investment of solar lamps are quite obvious.

In the solar power supply system, the performance of the battery directly affects the comprehensive cost, operation and service life of the system. In this scheme, the energy storage colloidal battery jointly developed by the company and the Institute of Metals, Chinese Academy of Sciences is selected. Compared with ordinary lead-acid batteries, it has a long service life, usually five to ten years. The battery is more suitable for cyclic charging and discharging of energy storage batteries by adopting appropriate anode and cathode alloy formula and active material ratio. The design of colloidal electrolyte can effectively inhibit the rust removal of active substances and the sulfation of electrode plates, thus delaying the performance degradation of the battery during use. And the deep charge-discharge cycle life of the battery is greatly prolonged. Select the LED light source of the fourth generation lighting products. When installing solar street lamps, there is no need to erect complex lines, just make a cement base and battery pit within the range of 1m and fix them with galvanized bolts.
