How to extend the service life of solar street lights

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 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 we will take you to scientifically analyze how long the service life of solar street lights can last.

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 powers the LED light source to make it glow.

1. 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.

2. Solar panels

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 20 years.

3. LED light source

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.

4. 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.

In general, the key to the service life of solar street lights lies in the battery. When purchasing 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 enough for daily discharge, then the battery is easily damaged, but the capacity of the battery is several times of the daily discharge, it 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.

5. 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. 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.

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.
