Is the life of solar lamp longer than that of ordinary electric lamp?

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 regulation that the maintenance fee of street lamps in residential quarters should be charged at one time according to the pure residential building area of 6 yuan/㎡, the led street lamp holder makes the initial investment of ordinary lamps much higher than that of solar lamps. In short, solar led street lamp manufacturers, comprehensive comparison, the characteristics of solar lamps to save investment is still relatively obvious. In the solar power supply system, the performance of led street lamps and batteries directly affects the comprehensive cost, operation and service life of the system. In this scheme, a new type of 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 the following outstanding characteristics in design and manufacturing technology: long service life, which is five to ten years under normal circumstances. 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 sulfation of electrode plates, and lead to street lamps, thus delaying the performance degradation of batteries in use. And the deep charge-discharge cycle life of the battery is greatly prolonged. So generally speaking, the life of solar lamps is much longer than that of ordinary electric lamps. I suggest you buy a solar lamp, which can last for a long time.
