How long can solar street lights last?

With the vigorous development of the construction of new rural areas, 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 still worry about its service life and think that it is a new product with immature technology and short service life. Even if the 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 Panel

Everyone knows the solar panel, which 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 one year.

Two, LED light source

The LED light source is composed of at least dozens of lamp beads containing LED chips, and the theoretical life is small, but normally it can reach about one year.

Three, street light pole

The street light pole is made of Q steel coiled pole, the whole is hot-dip galvanized, and the hot-dip galvanizing has strong anti-rust and anti-corrosion ability, so at least it is guaranteed not to rust.

Four, battery

The main batteries currently used in domestic solar street lights are colloidal maintenance-free batteries and lithium batteries. The service life of the gel battery is normal to one year, and the service life of the lithium battery is normal to one year. Some manufacturers guarantee that the life of colloidal batteries is up to one year, and that of lithium batteries is at least one year, which is completely exaggerated. In normal use, it is time to replace the battery, because the actual capacity of the battery will be much lower than the initial capacity by the year, which will affect the lighting effect. The price of replacing a battery is not too high. Just buy it.

Five, controller

Generally, the controller has a higher level of waterproof and sealing, and there is no problem in normal use.

In general, the key to the service life of solar street lights lies in 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, and the complete discharge is about the second time. If the capacity of the battery is only sufficient for the daily discharge capacity, the battery is easily damaged, but the capacity of the battery is several times the daily discharge capacity, which means that there will be a cycle in a few days, which greatly increases the life of the battery In addition, 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.
