How Long Do Solar Led Street Lights Last?

how long do solar led street lights last

In recent years, solar LED street lights are an increasingly popular choice for both residential and commercial properties. They are good for areas that with full sunshine and are difficult to connect to the grid economically or logistically. There are several advantages to solar street lights, including energy savings, being environmentally friendly, cost-effective, ease of installation, and requiring little maintenance. However, due to the high initial investment costs, we also need to take the lifespan of solar led street lights into consideration.  

How long do the solar led street lights last?  As far as solar street light systems are concerned, batteries play the most important role. Battery quality determines the lifespan of solar led street lights. If the system sizing is correct and adopts quality materials, a well-designed solar-led street light system with a good quality battery should last between 5 and 10 years.

In order to answer this question better, it is first necessary to understand the composition of these devices. Solar street lamps typically consist of four main components: the solar panel, the battery, the controller, and the LED light. The solar panel is responsible for converting sunlight into electrical energy, which is then stored in the battery via the controller. The LED light is used to illuminate the area during darkness. With proper care and maintenance, all of these components can last for many years. Yet, each of the components has its own lifespan. Solar street lights combine these parts together. Let’s go over these parts and find out how long is the lifespan of the led solar street lamp. 

1. Solar panel

It has become common knowledge that solar panels produce power for the entire light system. This device is made from crystalline silicon and has a lifespan of about 25 years. Maintaining solar panels during their use is also necessary if you want them to last for the expected amount of time. By absorbing solar energy, solar panels convert solar light energy into electrical energy, which is stored in rechargeable batteries. Therefore, the solar panel can’t be shaded during use. If the top of the solar panel is blocked by trees, the trees need to be pruned regularly. The surface of the solar panel should be cleaned in time if it has been used for a long time, is covered with dust or snow after heavy snow, etc. Its lifespan can easily reach 25 years if it is regularly maintained and the solar panels are used correctly.

2. LED light  

LED solar street lights are constantly being upgraded with the advancement of technology. LEDs are used as light sources in the new LED solar-powered street lights. As compared to high-pressure sodium lamps and other light sources, LED lamps have a lower light decay rate and a longer lifespan. In terms of energy consumption, LED light sources are among the most energy-efficient lights available. Its energy consumption is one-ninth that of incandescent bulbs and one-third that of other lamps. The device consumes relatively little energy but it lasts for a long time. The LED light source is composed of at least dozens of LED chips, with a theoretical life of 100,000 hours, which is normally about 22 years.

3. Battery

A battery plays an important role in determining how long a solar street lamp lasts. Lithium iron phosphate batteries typically last 5-10 years, while lead-acid batteries last 3-5 years. If you are buying a led solar street light, make sure you configure the battery to be larger than what the light comes with. In addition to its cycle discharge life, the battery’s lifespan is also determined by its capacity. Unlike other batteries, lithium iron phosphate batteries have a cycle life greater than 2000 cycles. In spite of its high cost, it is easy to install, small in size, pollution-free, and has a long lifespan. According to the following principles, battery capacity should be selected on the basis of meeting night lighting needs: First, as much solar cell energy as possible should be stored during the day. It must also be able to store enough electrical energy for continuous rainy days and nighttime lighting. Night lighting requires a larger battery capacity. The battery capacity is too large. A battery is always in a state of power loss, which reduces its lifespan and wastes energy. It is possible to have several consecutive days of rain or cloudy weather because the battery has several times the capacity of the daily discharge.

4. Controller

 A solar controller is a device that regulates the charging and discharging of batteries in a solar led street lighting system. Solar controllers are crucial to the proper operation of a solar lighting system, as they help to prevent overcharging and deep discharge of the batteries. Solar controllers also help to optimize the charging process, ensuring that the batteries are charged as efficiently as possible. There are two types of solar controllers: MPPT and PWM. MPPT controllers are more efficient than PWM controllers, but they are also more expensive. Solar controllers are an important part of any solar led street lighting system, and they can help to improve the efficiency of the system as well as prevent damage to the batteries. Solar controllers also play an important role in extending battery life. There are no problems with the controller for 8 years of normal use because of its high level of waterproofing and sealing.

Conclusion

Durability is one of the most important factors to consider when purchasing a solar-powered street light. After all, you want your investment to last for many years. The lifespan of a solar street light is determined by the quality of its components – specifically, the battery. A street light that uses top-grade materials can ensure a lifespan of 5 years. That’s a significant difference compared with conventional street lights, which need to be replaced much more frequently. Not only does this save you money in the long run, but it also reduces the amount of waste that ends up in landfills. When choosing a solar street light, be sure to find a reputable manufacturer that offers a good warranty period. With proper care and maintenance, your solar street light should provide years of trouble-free service.
