Now, many people will not be unfamiliar with solar street lamps, because now our urban roads and even our own doorways are installed, and we all know that solar power generation does not need to use electricity, so how long can solar street lamps last? To solve this problem, let’s introduce it in detail.
After replacing the battery with lithium battery, the life of solar street lamp has been greatly improved, and the life of solar street lamp with reliable quality can reach about 10 years. After 10 years, only some parts need to be replaced, and the solar lamp can continue to serve for another 10 years.
The following is the service life of the main components of the solar street lamp (the default is that the product quality is excellent and the use environment is not harsh)
1. Solar panel: more than 30 years (after 30 years, the solar energy will decay by more than 30%, but it can still generate electricity, which does not mean the end of life)
2. Street lamp pole: more than 30 years
3. LED light source: more than 11 years (calculated as 12 hours per night)
4. Lithium battery: more than 10 years (discharge depth is calculated as 30%)
5. Controller: 8-10 years
The above information about how long the solar street lamp can last is shared here. From the above introduction, we can see that the short board of the whole set of solar street lamp has been transferred from the battery in the lead-acid battery era to the controller. The life of a reliable controller can reach 8-10 years, which means that the life of a set of solar street lamps with reliable quality should be more than 8-10 years. In other words, the maintenance period of a set of solar street lamps with reliable quality should be 8-10 years.
