1. How long is the life of Solar street lights

As an environmentally friendly and energy -saving street light, Solar street lights are more concerned about the service life. So how long can Solar street lights be used?

Generally speaking, the life of Solar street lights is related to its accessories. The accessories of Solar street lights mainly include Solar panels, controllers, batteries, light sources, and light rods. The service life of different accessories will be different:

1. The service life of Solar panels is more than 20 years. After 20 years, Solar panels only have a certain light aging (about 30%), but it can be continued.

2. Then the controller, the general service life is about 8-10 years, depending on the original electronic original and use environment.

3. Next is a battery. In the past, Solar street lights generally use lead -acid colloid batteries. The service life of this battery is about 3 years. Generally, lead -acid batteries that are about to years may be very serious.If you can't meet it, you can't meet the demand for lighting.And now the battery is mostly used in lithium batteries. The high -low temperature attributes of lithium batteries are better than lead -acid colloid batteries. The number of cycles is more than lead -acid colloid batteries. The deep discharge energy is more than 2,000 times.More than 5 years.

4. In terms of light sources, the current Solar street lights are LED light sources. The good LED light source life can reach more than 11 years.

5. The service life of the light rod is relatively long. If it is used with hot -dip galvanized and rust -proof measures, the life span can be more than 20 years.

In summary, the main factor restricting the life of Solar street lights is the battery. Under normal circumstances, the life span of Solar street lights is 5-8 years, but most accessories can be used normally. Just replace the battery.

2. How to extend the life of Solar street lights

solar energy is a kind of green renewable energy, and it is also more energy -saving. Now many places use Solar street lights.The use of Solar street lights is limited. If you want to extend your life, the main point is to pay attention to the following points:

1. Use high -quality Solar panels

The main function of Solar panels is to collect light sources and convert light energy to electrical energy. The life of the Solar panels produced by regular manufacturers is relatively long. When buying, you should pay attention to the purchase of products with guaranteed quality.

2. Choose a light source with good heat dissipation

There are two positions that require heat dissipation in Solar street lights, one is the head of the lamp, and the other is the battery.Solar street lamps are generally used for LED lamp heads. We should buy a good cooling function lamp, so as to extend the life of LED lamp beads.

3. Use high -quality batteries

The battery is a strong backing of Solar street lights. If the battery life is not long, the service life of Solar street lights will not be long.Generally speaking, it is best to heat the heat dissipation effect that the lithium battery with aluminum -magnesium alloy shell has long life, fast heat dissipation, and the quality is very guaranteed.

4. Choose the right Solar street light controller

Solar street light controller is a central nervous system in the Solar lighting system, which is responsible for coordinating the work of Solar panels, lithium batteries and loads.It is the key component of the Solar street light lighting system. We must not be greedy for cheap controllers. It is recommended to choose a reputable manufacturer and buy a controller with a qualified certificate.

5. The process processing of the light rod

Solar street lights are mainly supported by light rods. The service life of the street light rod depends entirely on what kind of galvanized use. Cold galvanized Lights will rust after 1-2 months outdoors.Hidden dangers; good Solar street lights are hot -dip galvanized, and the service life can reach 20 years.
