How Long is the Lifespan of Led Solar Street Light?

Led solar street lights have the advantages of energy saving, environmental protection, easy installation, economical and practical, and provide more convenience for our night life. But no matter how many advantages led solar street lights have, we also need to consider the lifespan of solar street lights. Due to that the solar street light is not cheap, but it brings long-term benefits. The lifespan of solar lamps is much longer than that of ordinary electric lamps. If you want to know the service life of solar street lamps, you must first understand the composition of solar street lamps. Solar street light is an independent power generation lighting system, which is composed of batteries, street light poles, LED lamps, battery panels, solar street light controllers and other components. During the day, the solar panel converts light energy into electrical energy and stores it in the solar battery. At night, the battery supplies power to the LED light source to make it glow. Led solar street light can last longer than we expected if properly taken care of. Each of the component has its own lifespan. Solar street light integrate these components together. Let's go over these parts and find how long is the lifespan of the led solar street light? Everyone knows the solar panel, which is the power generation equipment of the whole light system. It is composed of silicon wafers and has a long lifespan, which can reach about 20 years. However, if you want to make solar panels reach the expected lifespan, you also need to pay attention to maintenance during use. The main function of solar panels is to convert solar light energy into electrical energy by absorbing solar energy, which is stored in rechargeable batteries. Therefore, the solar panel can not be shaded during use. If the top of the solar panel is blocked by trees, the trees need to be pruned regularly. Or if it is used for a long time, there is dust or snow on the solar panel after heavy snow, etc., it is necessary to clean the surface of the solar panel in time. If it is regularly maintained and the solar panels are used correctly, its lifespan can certainly reach 20 years. With the development of technology, led solar street lights are constantly upgraded. The new led solar street lights use LED light sources. The previous high-pressure sodium lamps and other light sources have serious light decay and have a short lifespan, while the light decay of LED lamps is only 3% a year. The LED light source is a low-energy-consuming product. Its power consumption is one-ninth of that of incandescent lamps and one-third of other lamps. It consumes very little energy, but has a long lifespan. The LED light source is composed of at least dozens of lamp beads containing LED chips, with a theoretical life of 50,000 hours, which is normally about 10 years. The key to affecting the lifespan of led solar street lights is the battery. Generally, the lifespan of lead-acid batteries is 2-4 years, and the lifespan of lithium iron phosphate batteries is 5-8 years. When buying a led solar street light, it is recommended to configure the battery to be larger. The lifespan of the battery is determined by its cycle discharge life. The cycle life of a lithium iron phosphate battery is more than 2000 times. Although expensive, it is easy to install, small in size, pollution-free, and has a long lifespan. The selection of battery capacity generally follows the following principles: First, on the premise of meeting night lighting, store the energy of solar cell components during the day as much as possible. At the same time, it must be able to store the electrical energy required for continuous rainy days and night lighting. The battery capacity is too small to meet the needs of night lighting. The battery capacity is too large. On the one hand, the battery is always in a state of power loss, which affects the battery lifespan and causes waste. The capacity of the battery is several times the daily discharge capacity, which can guarantee a longer number of consecutive cloudy and rainy days. The role of the solar controller is to control the solar panel to charge the battery and to supply and illuminate the led solar street lamp. A stable solar controller plays an important role in the lifespan of the battery. Generally, the controller has a high level of waterproof and sealing, and there is no problem for 6 years of normal use. As we mentioned above, quality of the components will affect the lifespan of led solar street light. Battery plays the most significant role in the street light system. Street light that adopt top grade materials can ensure the lifespan of 5 years. The led solar street light saves a lot of cost compared with conventional street lights. When purchasing the led solar street light, we should take all these factors into consideration. Be sure to find a reliable led solar street light manufacturer and check the warranty period of the solar street light.
