Solar Street Light is an independent lighting system. Simply put, it generates electricity for its own use. It does not need to be connected to 220V thermal power. During the day, solar energy is converted into electrical energy through battery panels and stored in lithium batteries. When it is dark, the intelligent street light control system uses lithium batteries. Power the solar street light source. Generally, the number of continuous rainy days in a normal design is 7 days. If the battery power detection automatic power reduction controller is used, it may be extended to about 35 days. And we know that under normal circumstances, there will be no sun for one month in a row, so it is possible to achieve lights on every night of the year. For the battery panel, it is made of pure silicon board as the main material, and the life span can reach more than 25 years, followed by the led light source, the life span is more than 50,000 hours, and the normal use can be as long as about 10 years. Next is lithium Batteries, currently commonly used lithium batteries for solar street lights in China, with a life span of more than 5 years.
