With the vigorous development of new rural construction, the sales of solar street lights are rising rapidly, and many rural areas regard solar street lights as an important choice for outdoor lighting. However, many people are still worried about its service life and think it is a new product with immature technology and short service life. Even if solar street light manufacturers provide a three-year warranty, many people still have concerns about it. Today, the technicians of solar street light manufacturers will take everyone to scientifically analyze how long the service life of solar street lights can reach.
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. There is no need to connect to the mains. 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.
1. Solar panels
Everyone knows that the solar panel is the power generation equipment of the whole system. It is composed of silicon wafers and has a long service life, which can reach about 20 years.
2. LED light source
The LED light source is composed of at least dozens of lamp beads containing LED chips, and the theoretical life span is 50,000 hours, which is normally about 10 years.
3. Street light pole
The street light pole is made of Q235 steel coil, the whole is hot-dip galvanized, and the hot-dip galvanizing has strong anti-rust and anti-corrosion ability, so at least 15% is not rusty.
4. Battery
The main batteries currently used in domestic solar street lights are colloidal maintenance-free batteries and lithium batteries. The normal service life of gel batteries is 6 to 8 years, and the normal service life of lithium batteries is 3 to 5 years. Some manufacturers guarantee that the life of gel batteries is 8 to 10 years, and that of lithium batteries is at least 5 years, which is completely exaggerated. In normal use, it takes 3 to 5 years to replace the battery, because the actual capacity of the battery in 3 to 5 years is much lower than the initial capacity, which affects the lighting effect. The price of replacing a battery is not too high. You can buy it from the solar street light manufacturer.
5. Controller
Generally, the controller has a high level of waterproof and sealing, and there is no problem in normal use for 5 or 6 years.
Generally speaking, the key that affects the service life of solar street lights is the battery. When buying solar street lights, it is recommended to configure the battery to be larger. The life of the battery is determined by its cycle discharge life. The complete discharge is about 400 to 700 times. If the capacity of the battery is only sufficient for the daily discharge, the battery is easily damaged, but the capacity of the battery is several times the daily discharge, which means that there will be a cycle in a few days, which greatly increases the life of the battery. , And the capacity of the battery is several times the daily discharge capacity, which means that the number of continuous cloudy and rainy days can be longer.
The service life of solar street lights also lies in the usual maintenance. In the initial stage of installation, the construction standards should be strictly followed, and the configuration should be matched as much as possible to increase the capacity of the battery to extend the life of the solar street lights.
