Compared with ordinary solar led street lights, smart solar street lights have more intelligent control functions. Its working principle is the same as that of solar street lights. It charges and stores electricity during the day and discharges it to light up the streetlights at night. However, smart solar street lights will optimize the lighting time and brightness of solar street lights according to actual conditions, which can greatly reduce energy consumption, protect batteries, and extend the service life of solar powered outdoor street lights.

As environmentally friendly and energy-saving lighting equipment, solar street lights have great advantages over traditional street lights, but there are also some limitations, mainly reflected in:
Affected by the weather: Solar LED street lights are greatly affected by the weather and rely too much on sunlight. Under sunny weather conditions, the lighting effect is very good. However, continuous rain or insufficient light may cause problems such as the solar street lights not lighting up.
High initial investment cost: The initial investment of commercial solar powered street lights is relatively large because of their relatively high requirements for solar panels, batteries, light sources, etc., but in the long run, the economic benefits are still good.

Solar lights generally cannot be effectively charged through windows because:
1. The intensity of light will be attenuated because glass will block some of the energy of sunlight, especially since some of the glass will have heat insulation or UV protection coating, which will reduce the penetration of light.
2. Working requirements of solar panels: Solar panels generally require strong direct sunlight to efficiently convert photoelectricity. Through glass, the light will become scattered, and the intensity is not enough, so it cannot meet the charging needs of solar lights.

You can extend the working time of solar street lights in the following ways:
Improve charging efficiency: Use high-efficiency solar panels to improve photoelectric conversion efficiency.
Enhance energy storage capacity: Increase battery capacity, store more electricity, and extend lighting time.
Optimize energy consumption: Use smart controllers and other methods to optimize the brightness and lighting time of solar street lights and minimize energy consumption while ensuring lighting.
Regular inspection and maintenance: Keep solar panels clean and replace components promptly.

Yes, solar street lights can stay on all night, but many factors need to be considered, such as the configuration of the commercial solar street lights, the storage capacity of the batteries, and the installation location.

Yes, solar street lights will light up on cloudy days. They are mainly powered by the electricity stored in batteries. If the battery does not store enough electricity, the brightness of the street lights may decrease, and the working time may also be reduced. Some high-end streetlights are also equipped with energy storage functions, which can store excess electricity when there is sufficient light to ensure normal operation when there is insufficient light.
