Although say is a energy saving security lights, solar street lamps but there is a certain limit for its use. Solar panels in different time, different place, as a solar cell output power is different, is not, to some think, as long as there is sunshine will fistfight rated output power, set up artificial solar cells under the lights can be normal use. Solar cell output power depends on solar radiation, sunlight, temperature distribution and the solar cells work. Per square meter area computation, the output power of solar cell is about 120 w, with the improvement of conversion efficiency, the output power also increases accordingly. The choice of the solar modules output, according to the solar lamp light source power, using time and geographical conditions to determine the local climate. So, solar street light in use process, if there is a solar battery was alone leaves shade shade for a long time, obscured monolithic solar cells in the intense sun will heat and damage, even cause the damage of the solar cell components, solar road lights can't normal use, in order to prevent the occurrence of such a situation, generally is placing solar cell tilt, make the solar cell surface adhesion obstructions.
