How To Extend Service Life of Solar Powered Street Light?

As a lighting fixture that uses renewable energy, solar powered street light has zero emission and no pollution, which is in line with the current demand for energy conservation and emission reduction. Now many lighting projects in many parts of the world regard solar powered street lights as the first choice. Government departments have also issued subsidy policies for solar powered street lights one after another, and the widespread promotion of solar powered street lights is justified. The service life of solar powered street lights is a problem that users are most concerned about. In the process of use, we should pay more attention to prolong the service life of solar street lights.

1. Choose the right battery

Solar powered street lights are mainly composed of photovoltaic panels, batteries, controllers, light sources, and light poles. One of the most easily damaged is the battery, which is also the most expensive accessory. Other accessories have a service life of at least ten years, only the battery is often used for a few years and has no capacity. Therefore, extending the service life of solar powered street lights is basically equivalent to extending the service life of batteries. If the voltage of the battery has been unstable, or has been overcharged and overdischarged, the lifespan of the battery will definitely be reduced in this case. Generally speaking, more stable batteries are more expensive, but they can be used for a long time. Most of the current solar street lights use lithium iron phosphate batteries or ternary lithium batteries. The lithium iron phosphate battery has a large number of charging and discharging times, which can reach more than 2000 times, but it is not resistant to low temperature, and the capacity is significantly reduced at low temperature, and the charging and discharging efficiency is also significantly reduced. Therefore, it is best to choose the corresponding battery in different occasions.

2. Choose the right lighting source

Different types of light sources will also affect the service life of solar powered street lights. Now the commonly used light sources for solar street lights are LEDs, energy-saving lamps, and electrodeless lamps. The average lifespan of energy-saving lamps is more than 6,000 hours, and the lifespan of LED lamps is generally more than 50,000 hours. Energy-saving lamps can be used for more than 2 years and LED lamps can be used for more than 10 years. Therefore, the service life of solar powered street lights using high-quality LED light sources must be longer than that of ordinary street lights. However, some solar street light manufacturers insist on using other light sources, such as low-pressure sodium lamps, low-pressure fluorescent lamps, etc. These light sources are cheap, but the service life is relatively short and the quality is relatively poor.

3. Choose street light with good heat dissipation

The traditional street lights in the past had poor heat dissipation, so they often failed. There are two places for solar street lights to dissipate heat, one is the lamp head, and the other is the battery. Solar powered street lights generally use LED lamp caps. We should buy lamps with good heat dissipation function, so as to prolong the service life of LED lamp beads. EXC-CR-Z02 solar street light has a very good heat dissipation function, adopts LED light source, high-quality MPPT controller, and low current is suitable for long-distance transportation and storage.

4 . Choose the right street light controller

The function of the solar controller is to control the solar panel to charge the battery and to supply power to the solar street lamp. Especially when working under critical conditions such as insufficient battery power or undervoltage operation, a controller with high precision and stable performance will play a key role; controllers with different prices have different stability and service life. If you want to use the solar powered street light for a longer time, you can also buy a better quality controller.

In short, if you want to extend the service life of solar led street lamp, you still need to pay more attention to the above aspects. The longer the solar street light is used, the more cost can be saved.
