with the development of solar technology, solar LED street light entered people's lives, especially in rural areas. The new rural construction projects in most of China's rural areas, and solar led street lamp because of its advantages of energy saving, environmental protection, simple installation, loved by people. As a result, solar led street lamp is widely used in rural roads, many clients often ask why the solar led street lamp lighting time suddenly shortened. Next, let the king of the street lamp manufacturers manager with your brothers analysis the cause of the problem. 1. The solar cell ( Lithium battery) Decrease the capacity when the solar street lamps lighting at night time shortened, the solar cell ( Lithium battery) Storage capacity reduction is the first factor to consider. Solar led streetlight energy supply and stored by the battery ( Lithium battery) To complete. Now, the battery technology ( Lithium battery) Have a life. The commonly used batteries including solar street lamps colloid lead acid battery and lithium battery. Colloid service life of the lead-acid battery for 3 - in general The service life of 5 years, lithium battery for 5 - Eight years or longer. If this period using solar street lamp, after several years of development, the lithium battery is used, basically lithium batteries have more advantages than batteries! 2. Rainy days is too long on a rainy day, because the light is weak, the solar cell module cannot convert or conversion is low, lead to charge less than the discharge, so the battery ( Lithium battery) Power shortage for a long time, resulting in lighting a shorter time. At this point, as long as the weather improves, charging can restore the original lighting time in two days. ( This usually occurs in the south of China, because in the summer rainfall in the south of increase, especially during the rainy season, this situation is the most likely to happen) 3. Solar photovoltaic panels solar photovoltaic panels dirt or damage to the main function is to convert light energy into electrical energy. Solar cells exposed for a long time, especially in the dust, the dust easily. The excessive accumulation of dust can produce adverse effect on the conversion efficiency, a direct result of charging amount is lower than the discharge, resulting in lighting a shorter time. In this case, it is necessary to clean photovoltaic panels and its charging for two days to restore the initial lighting; If the illumination time is very short after cleaning, which means that the solar photovoltaic panels may be damaged, need to replace new one. 4. The quality of the product itself because of the current market chaos, the appearance of many middlemen, the product quality is uneven, because they are not manufacturers, they don't understand the technology, they only pursuit of profit, completely ignore the product quality problems in the late. Find formal manufacturers cooperation, therefore, it is extremely important, so can the problems in the first convenient product maintenance and replacement, to ensure normal lighting! In solar led street lamp lighting time is short, don't panic, according to the street lamp manufacturers to provide the methods for inspection, repair and replacement. Street lamp can restore lighting.
