Whether it is a solar street light or a traditional street light, we will pay attention to one question when choosing, that is, how long can the street light be used? The longer the street light is used, the higher the economic benefits you get, especially the solar street light, which is almost zero cost during use because it relies on free clean energy—solar energy, so there is no electricity bill, and the maintenance cost is very low. Therefore, the longer the solar street light is used, the higher the economic benefits. In the next article, let’s explore how long the
solar street light can be used.
How long is the lifespan of a solar street light outdoor?
The lifespan of a solar street light generally depends on the service life of its components. The components of a solar street light include solar panels, batteries, LED light sources, controllers, light poles, etc., and the service life of different accessories is also different.
1. Solar panels:
The service life is generally 20 to 30 years. In long-term use, the output power of solar panels will decrease year by year. High-quality solar panels can still maintain about 80% of the original power generation capacity after 20 years and can continue to be used.
2. Battery of solar street light:
The lifespan of the battery is closely related to the battery type. In the past, solar street lights outside usually used lead-acid batteries, which had serious aging problems and could only be used for 3-5 years. Modern solar street lights mostly use lithium batteries, which have very good thermal stability and safety. As long as they are properly maintained, they can be used for 10–15 years.
3. Solar street light LED light source:
The service life of the LED light source of solar street lights is usually 50,000 to 100,000 hours.
4. Solar street light controller:
The service life of solar street light controllers is usually 5 to 15 years. High-quality controllers can extend the service life of
solar street lights outdoors under proper working conditions.
5. Solar street light poles:
The lifespan of solar street light poles is usually 10 to 30 years, depending on the material, design, environmental conditions, maintenance, and installation quality. High-quality materials and good maintenance can significantly extend the service life of street light poles and ensure their stability and reliability under various conditions.
What are the factors that affect the lifespan of solar-powered street lights?
1. Environmental conditions.
Harsh climatic conditions, such as strong wind and sand, heavy salt fog, large temperature changes, and light intensity and humidity at the installation site, will affect the life of solar street lights.
2. component quality.
3. Installation and maintenance.
Soil conditions, humidity, salinity, etc. at the installation site will also affect the corrosion resistance and stability of the street lights. Regular inspection, cleaning, and maintenance of solar LED street lights can ensure the normal operation of all components and extend their service life.
4. Frequency of use.
Although LED light sources are relatively tolerant of frequent switching, the service life of controllers and batteries may be affected.
Why do your solar street lights last so short?
1. Product quality issues.
Due to the increasing demand for solar-powered street lights, more and more solar street light manufacturers have begun to emerge, but the solar street lights on the market are mixed, and the product quality is uneven. Therefore, when you buy solar street lights, you must buy them from regular manufacturers to ensure product quality and after-sales service.
2. The solar panel is dirty or damaged.
Solar panels are exposed to the outdoors for a long time. Their function is to convert the received solar energy into electrical energy. If there is a lot of dirt on the solar panels, it will affect the efficiency of receiving and converting sunlight. Without sufficient electricity, the lighting time of
solar-led street lights cannot be effectively guaranteed.
3. Battery capacity decay.
If the lighting time of solar road lights becomes significantly shorter, the first thing you need to consider is the battery decay problem, because the power supply and storage of solar street lights are completed by batteries, and the service life of batteries is limited. The service life of lead-acid batteries is only 3-5 years, and the service life of lithium batteries can reach 10-15 years.
4. Insufficient sunshine time.
If it is cloudy and rainy continuously, the light intensity will weaken, and solar energy cannot be effectively converted into electrical energy, resulting in less charging than discharging, which will also shorten the lighting time of solar LED street lights.
How to extend the use time of solar street lights?
1. Perform maintenance inspections regularly.
During the use of
solar road lights, it is necessary to regularly inspect and maintain solar street lights, find and solve problems in time, so as to maintain the normal and stable operation of solar street lights.
2. Clean solar panels regularly.
Solar panels are key components that affect the efficiency of photoelectric conversion. It is important to ensure that the solar panels are clean and clean the dirt in time to avoid affecting energy reception and conversion.
3. Check the battery.
The energy storage and power supply of solar road lights need to be completed through batteries, so it is important to ensure that the performance of the battery is intact. If there is a serious attenuation problem, it must be replaced in time.
4. Choose the installation location reasonably.
The installation location of the solar street light must be selected in a sunny and unobstructed place, so as to ensure that the solar panel can receive sufficient sunlight and the solar street light can obtain sufficient energy, which can provide people with stable and reliable lighting.
Conclusion
If you are looking for an energy-saving, environmentally friendly, economical, and durable lighting solution, solar street lights must be your good choice. As a user of solar street lights, you only need to choose a good product and install it in a reasonable location to get stable and reliable lighting. The service life of solar street lights is closely related to the quality of the product you choose and your maintenance of the street lights.
