Solar energy is tremendously available as the most important energy source now.  and this energy is used for many applications, including street lights.  

As a key part of the solar street light, keep the efficiency of the solar panel is very important. While, as we know, the accumulation of dust particles,  deposits left by birds or the fallen leaves, on the surface of the solar panel will reflect the incident light falling on the panel,  preventing a portion of the radiation from being used. This problem could reduce the ability of solar cells to absorb solar energy, which greatly affects its efficiency, reducing the lifetime of its storage power after a few months from its installation,  leading to permanent or long-term failure, especially in the desert areas. 

There are several possibles of cleaning methods (wind clearing, rainfall, washing with various liquids, air blowing, wiping, vibrating the surface, and so on.) Although these cleaning methods are workable, the cost is expensive.  Much research studied the effect of dust, impurities on the solar panel and how to deal with this problem. 

It is also important to take the costs of cleaning and maintenance into account. Is there a simple mechanism (Autonomous cleaning unit) that can add to the light, without any change in the panel structure, and easy install and disassemble?

Thanks for the effort of our D & R department and the valuable comments from friends around the world. NOMO launched Irobot series solar street light, which has the autonomous cleaning unit, and settable cleaning time makes the light is more intelligent, it's a real tailor light. 

Besides of the all in one Autonomous cleaning Solar Street Light, we launched a new series: All in two Autonomous cleaning Solar Street Light, which can meet super brightness and longer backup days, such as highway road lighting.
