What Factors Affect Solar Street Light lifetime
The solar street light has many advantages, so it can be widely installed and used, such as no electricity fees, save energy and so on. It¡¯s important that we need to purchase a stable quality solar street light to get a stable return.
Then let¡¯s analyze what factors will affect the life of a solar street light. We will analyze them from the following main aspects.
Working environment of lights
The working environment of lights has a vital impact on lifetime, especially outdoor solar street light. Some main environmental impact factors are temperature, humidity, dust and so on.
Why does temperature affect the solar street lights lifetime? Because solar street lights¡¯ batteries are sensitive to environmental temperatures, such as the ambient temperature of lithium ternary batteries can not exceed ¨C 20 C ¨C 40 C, because their operation ambient temperature only can reach ¨C 10 C ¨C 60 C. Due to Solar Street lights are used for outdoor places, so the water-proof performance of the light is very important, otherwise the controllers, batteries and other core devices will be damaged.
Local climate conditions and sunshine time
An important factor to consider is to check the local climate conditions and sunshine time. The lighting time has a lot to do with the sunshine time and intensity of sunlight. This will directly affect the amount of energy absorbed by the solar panel. The more energy the solar panel absorbs, the more electricity it can convert, which can ensure sufficient Lighting time. Generally, the accumulated sunshine duration in the north (the number of sunshine hours in a year) is longer, and there is more precipitation and cloudy days in the south, so the sunshine duration is less, which directly affects the lighting time.
Another point is that the local continuous rainy days. Solar street lights absorb much less energy than in sunny days. If the local continuous rainy days are longer, we must calculate it first when we choose the specification of solar street lights , Larger solar panels and larger battery are very important, ensure that solar street lights can keep working normally in long rainy days. At this time, we need professional and guaranteed solar street light manufacturers.
Great material components
Solar panels, batteries, and controllers are the three core parts of the solar street light, especially the battery part. If we choose some core components which are not good quality, it will seriously affect the lifespan. We often hear customers¡¯ feedback from us that a large number of solar street light purchased from a merchant has failed in 2-3 months, usually, this situation is due to the manufacturer¡¯s selection of bad materials.
Factors affecting the lithium battery lifespan
Do not install it near big trees or walls.
This is more likely to cause damage. The solar panel of the solar street light cannot absorb sunlight and cannot store electricity. As a result, the lithium battery will be in a state of non-saturation for a long time, or even in a state where no electricity is available. As a result, the street light cannot be powered or is intermittent. The power supply phenomenon will affect the life of solar street lights and the life of lithium batteries, so the installation location is very important.
The lithium battery charge is too saturated
When charging a lithium battery, in addition to worrying about insufficient charging and affecting its service life, you must also worry about overcharging. Excessive charging will also cause damage to the lithium battery, especially the long-term oversaturated charging state is more harmful Because long-term charging is too saturated, it will affect the internal electrochemical of the lithium battery, resulting in excessive power loss, and the long-term charging will cause the battery to run out of the heat, which will cause the lithium battery to bulge or It is a scrapped situation, so the lithium battery should have a control system. After the battery is fully charged, it will stop charging itself, so that the service life will be longer.
We must prevent lithium batteries from over-discharging.
The depth of discharge of a lithium battery when in use is closely related to the number of battery charge and discharge cycles (lifetime). Because under severe discharge conditions, the battery can no longer be activated to the state or even scrapped. Different discharge rates have different discharge times and termination voltages, and the effective capacity released is also different, and is affected by the ambient temperature and has different performances. Maintenance personnel should pay attention to it and set it in the monitoring unit strictly according to the relevant data. It must not be changed arbitrarily, so this aspect is also very important, and maintenance personnel should keep in mind.
This will not happen much compared with solar street lights, because solar street lights are usually used at night and do not work too long.
So if you want to buy a solar street light 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 light product you purchased will be applied to. Let them consider the environmental impact factors in advance and customize the product for your project.
The key to the life of solar street lights is battery. If the battery decays quickly, the lighting time will be shorter and shorter soon. If you use A class lithium LiFePO4 battery, the attenuation is small, and 10 years Lifetime. Tachyonlight always takes quality as the first priority and insists on using A Class lithium iron phosphate battery.
