With the vigorous development of new rural construction, the sales of
solar street lights have risen rapidly. Many rural areas regard solar street lights as an important choice for outdoor lighting. However, there are still many people who worry about its service life, thinking that it is a new product with immature technology and short service life. Even if the solar street light manufacturer gives a three-year warranty, many people still have concerns about it. Today, the solar street light manufacturer Xinhe Lighting will take you to scientifically analyze how long the service life of solar street lights can be. The 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. No need to connect to the mains, the solar panel converts light energy into electrical energy during the day and stores it in the solar battery, and at night the battery supplies power to the LED light source to make it glow. 1. Street light pole The street light pole is made of Q235 steel coiled rod, the whole is hot-dip galvanized, and the hot-dip galvanized anti-rust and anti-corrosion ability is strong, so at least 15% is guaranteed not to rust. 2. Solar panels We all know solar panels, which are 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. 3. LED light source LED light source is composed of at least dozens of lamp beads containing LED chips, with a theoretical life span of 50,000 hours, which can normally reach about 10 years. 4. Controller Generally, the waterproof and sealing level of the controller is relatively high, and there is no problem in normal use for 5 or 6 years. In general, the key to affecting the service life of solar street lights is the battery. When purchasing solar street lights, it is recommended to configure the battery to be larger. The life of the battery is defined as its cycle discharge life, and the complete discharge is about 400 to 700 times. If the capacity of the battery is only enough for the daily discharge, then the battery is easily damaged, but the capacity of the battery is several times the daily discharge, which means that it takes a few days to have a cycle, which greatly increases the life of the battery. , and the capacity of the battery is several times the daily discharge, that is, it can ensure that the number of continuous rainy days is longer. 5. Batteries The main batteries used in domestic solar street lamps 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 the life 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 after 3 years and 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. The service life of the solar street light also depends on the necessary maintenance. In the early stage of installation, it is necessary to strictly follow the construction standards, and try to match the configuration reasonably, increase the capacity of the battery, and thus prolong the life of the solar street light.
is emerging as one of the most popular solar lights, moving beyond its solar led flood lights suppliers benefits, with conclusive scientific evidence suggesting the positive role play in solar led flood lights suppliers.
Satisfying our customers with the appropriate level of quality is a primary goal and a fundamental element as solar lights of our business mission.
The trend toward using solar led flood lights suppliers solar lights to ease solar led flood lights suppliers, once established, soon extended into such additional fields as solar led flood lights suppliers and solar led flood lights suppliers.
