BS-AIO-TL series， Solar panels play a very important role in the entire charging process. If the solar panel of a street light has not been cleaned for a long time, a lot of dust or bird excrement is accumulated on it, which will greatly affect the charging efficiency of the solar panel. As a result, insufficient charging, low battery power, short lighting times, or very dim lighting. Therefore, our integrated street light with automatic cleaning function can well avoid the above problems.
