Nowadays, solar street lamps can be seen everywhere in China’s urban streets. It is the leader in new energy lighting equipment. On the road of development in the future, it can be imagined that it will be more widely used. The electric energy generated by the endless solar energy in the daytime will bring light and infinite convenience to everyone at night.
When installing solar street lamps, there is no need to embed cables and excavate roads, which saves manpower and material resources. At the same time, it saves energy, especially in saving electric energy. China will add 50 million outdoor lights every year. If solar street lamps account for one-thousandth, it can save hundreds of millions of kwh of electricity for the country in a year. Its power saving can not be underestimated.
At present, solar street lamps have been effectively used in urban construction, road lighting, courtyard lighting and other fields, especially in new rural road construction and remote mountain areas without electricity. The solar street lamp can work normally, which is naturally inseparable from its “heart”. Now let’s explain where the “heart” of solar street lamps is!
Its “heart” – solar panels. The reason why solar panels play a vital role is that the whole source of power generation depends on them. During the day, solar panels convert the absorbed solar energy into electric energy through a series of reactions to provide light. Therefore, the status of solar panels is very important. To improve the service life of solar street lamps, we need to use high-quality solar panels. Only qualified solar panel manufacturers can produce such solar panels.
Solar panels usually include monocrystalline silicon and polycrystalline silicon. Silicon materials with different production processes also affect the efficiency of solar panels. Monocrystalline silicon is produced by special processes and its purity is higher than polycrystalline silicon. Therefore, in order to obtain excellent photoelectric conversion efficiency, monocrystalline silicon solar panels are recommended, but its price is slightly higher than polycrystalline silicon. However, the street lamp life of this solar panel is much longer than that of ordinary products. In the long run, the cost performance is still very high, but as the purchaser, finally, you have to choose according to your own needs.
