solar street light lifetime

All in one solar led street light has many advantages, so it can be widely installed and used, such as no electricity fees, no wire laying cost, and so on. But because the first purchase cost of all in one solar street light is higher than the ordinary AC LED street lamps in terms of unit price, we need to purchase stable quality. Long-life solar street lights, let our investment get a stable return.

So let’s analyze what factors will affect the life of a solar street lamp. We will analyze them from the following three main aspects.

Operation environment conditions

The working environment of lights has a vital impact on lifetime, especially outdoor solar street lights. Some main environmental impact factors are temperature, humidity, dust, and so on. Why does temperature affect the solar street lamps’ lifetime? Because solar street lamp batteries are sensitive to environmental temperatures, such as the ambient temperature of lithium ternary batteries can not exceed – 20 C – 40 C, LUXMAN seldom uses such batteries, but chooses lithium iron phosphate batteries, because their operation ambient temperature can reach – 10 C – 60 C. due to Solar Street light used for outdoor places, so the water-proof performance of the lamp is very important, otherwise, it will lead to controllers, batteries and other core devices into the water, thus directly extinguishing the lamp.

Material Selection

Solar panels, batteries, and controllers are the three core parts of the solar street lamp, especially the battery part. If we choose some core components which are not of good quality, it will seriously affect the lifespan. We often hear customers’ feedback from us that a large number of solar street lamps purchased from a merchant has failed in 2-To 3 months, usually, this situation is due to the manufacturer’s selection of bad materials.

Operation Time

This will not happen much compared with solar street lamps, because solar street lamps are usually used at night and do not work too long.

So if you want to buy a solar street lamp product with stable quality, please choose a regular manufacturer. In addition, before purchasing the product, tell your supplier what kind of environment the solar street lamp product you purchased will be applied to. Let them consider the environmental impact factors in advance and customize the product for your project.

The life of high-quality solar-powered street lights can exceed 10 years. In the past, the life of street lights was only 3-5 years, because of the use of lead-acid batteries or other short-life batteries. Now solar lamps generally use lithium iron phosphate batteries, which have a life of more than 10 years. The latest CATL era batteries can already have a life of up to 16 years. Its life impact is mainly due to the short life of some components, especially batteries, followed by light source controllers and solar panels. Now let’s analyze these components, which will mainly affect the life of solar street lights.

Lighting source:

Now the solar street light usually uses the LED light source. After years of technological development, the life of the LED light has been stable. The good quality led light can theoretically reach 50,000 hours, 10 hours a day, and can be used for more than 10 years. After years of the practical application of LUXMAN, the outdoor LED light can be achieved more than 10 years of lifetime.

Batteries:

Batteries are more complex. Besides operation temperature and waterproof performance, the types of batteries are also the key factors affecting the life of LED solar street lamps. For example, the cycle times of ordinary lithium-ion batteries are about 500-600 times, while that of lithium iron phosphate batteries(LiFePO4)can be about 3000 times, which will influenceLED solar street lamps lifetime, LUXMAN solar street lamp provides three-year quality assurance because of adopting the LiFePO4 batteries. According to our practical application over the years, it is found that the actual life of the solar street lamp using LiFePO4 batteries can totally reach 10 years lifetime. Especially now, the latest battery life of the Ningde era can be used for 16 years

Solar panels

After years of development, solar panels have become a very mature technology, with a service life of more than 20 years.

Solar Controller:

The controller provides controlling, monitoring, protection of the battery, and working status of the load, etc. The controller adopted now is a constant current integrated controller, which integrates drive and control as its name implies, and can be used for 8-10 years.If this is properly maintained and replaced, it can continue to be used.

Through the above mentioned, a solar street light adopted good quality material with good performance, the lifespan can reach 10 years, and the key component affecting the life of solar street lamp is a battery. But now the latest battery life of the CATL can be used for 16 years, and later solar lamps can live longer.
