Solar led street light is simpler and more convenient than ordinary street light in terms of design and installation, which makes it easy to be accepted by mass consumers. Moreover, the advantages of energy conservation, environmental protection and long service life have increased people's demand for it. When in normal use, paying attention to maintenance can prolong the service life of solar LED street light.Take a solar panel as an example. During normal maintenance, the azimuth angle of the solar panel should be checked for branches, leaves or other foreign objects. Whether there are cracks, dust accumulation and dirty lights on the surface in the shadow area of other objects. Whether the monomer is cracked or not and whether the connecting line is flat or not are all within the scope of the inspection.In the solar LED street light using system, the storage battery is a big difficulty in maintenance, because the normal storage battery has a service life of 2-3 years at present, and the charging and discharging conditions of the storage battery should be regularly checked during its service life, and whether there is corrosion or contact on the electrodes or wiring should be observed at any time.
