Led solar street light has the benefits of electricity saving, environmental protection, smooth installation, low-cost and practical, and offers extra convenience for our nighttime lifestyles.
The lifespan of solar street lamps is plenty longer than that of normal electric-powered lamps. If you need to realize the provider lifestyles of solar street lamps, you ought to first recognize the composition of solar street lamps. Solar street light is an independent electricity-era lighting fixtures system, which consists of batteries, street light poles, LED lamps, battery panels, solar street light controllers, and different components. So, what factors affect the lifespan of solar street lights?
Now the solar-powered street light usually uses the LED light source. After years of technological development, the life of the LED light has been stable. The good quality led light can theoretically reach +100000 hours, and can be used for more than 10 years. Polybrite solar street lights use bridglux LED chips from USA, with high brightness, and luminous efficiency can reach up to 180lm/w.
Solar panel is the power generation equipment of the solar street lighting system. It is composed of silicon wafers used colloquially for a photo-voltaic (PV) module which has a long lifespan(more than 20 years).
However, if you want to make solar panels reach the expected lifespan, you should pay attention to maintenance during use. The main function of solar panels is convert solar light energy into electrical energy stored in rechargeable batteries. The solar panel can't be shaded during use, you should prune trees regularly if the top of solar panel is blocked. It is necessary to clean the surface of solar panel in time, if it used for a long time, mabye there is dust or snow on solar panel after heavy snow, etc.
Rechargeable batteries are more complex. Besides operation temperature and waterproof performance, the types of batteries are also the key factors affecting the life of LED solar street lamps. Generally, the lifespan of lead-acid batteries is 2-4 years, and the lifespan of lithium iron phosphate batteries is 5-8 years. The lifespan of the battery is determined by its cycle discharge life. For example, the cycle times of ordinary lithium-ion batteries are about 500-600 times, while that of lithium iron phosphate batteries(LiFePO4) can be about 2000-2500 times.
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. If the battery capacity is too large, the battery is always in a state of power loss, which affects the battery lifespan and causes waste. The capacity of the battery is six times the daily discharge capacity, which can guarantee a longer number of consecutive cloudy and rainy days.
The working environment of lights has a vital impact on lifetime, especially outdoor solar street light. Some main environmental impact factors are temperature, humidity, dust and so on. Why does temperature affect the solar street lights lifetime? Because solar street lights batteries are sensitive to environmental temperatures, such as the ambient temperature of lithium ternary batteries can not exceed -20C to 40C, because their operation ambient temperature only can reach -10 C to 60C.
So if you want to buy a solar street light product with stable quality, please choose a regular manufacturer. In addition, before purchasing the product, tell your supplier what kind of environment the solar street light product you purchased will be applied to. Let them consider the environmental impact factors in advance and customize the product for your project.What should I Consider When Buying Solar Street Light?
