Important factors restricting the application of solar street lamps

March 27, 2022

The application of solar energy will become more and more extensive with the shortage of traditional energy sources. In particular, the field of solar power generation has developed into a mature sunrise industry in just a few years. One of the most important factors limiting solar power applications today is price. Take a solar street light with two channels as an example. The total load of the two roads is 60 watts, and the solar panel needs about 160W. According to the calculation of 10 yuan per watt, the cost of the battery board is 1600 yuan, plus 180AH. The battery pack cost is also around 1200. The one-time input cost of the entire street lamp is much higher than that of the city circuit lamp, which causes the main bottleneck restricting the application of solar street light. The service life of the battery in the whole street lamp system application can be said to be the lowest among all components. The general battery life is three or five years, but in fact the general battery will be dissatisfied after one or even six months. Some actual charging rates are likely to drop to around 50, which will inevitably affect the normal night lighting during continuous rainy days, so it is very important to choose a better battery. In the practical application of many solar street lamps, solar street lamps in many places cannot meet the normal lighting requirements, especially in the rainy days. In addition to the use of poor quality related components, another major reason is to reduce the components. Cost, not designed according to demand, reducing the use of battery panels and batteries, so that the street lights can not provide illumination in rainy days.
