The life of other accessories of solar street lights can last over 10 years, but solar street light battery usually needs to be replaced after 3-5 years, so the key is the battery life and quality that influenced the solar street lights life.
All in one solar street light is an independent power generation lighting system, it is composed of battery, solar street light pole, LED lights, battery, solar street light controller and other components.
No need to connect to the mains, the solar panel converts light energy into electrical energy during the day and stores it in the solar battery, at night the battery supplies power to the LED light source to make it shine.
1、Solar led lights panels
We all know the solar panel, it is the whole system of power generation equipment, it is composed of silicon wafers, the service life is very long, can reach about 20 years of life.
2、Solar led LED light source
LED light source is composed of at least a few dozen light beads containing LED chips, theoretical life of 50,000 hours, normal is by can reach about 10 years.
3、Solar led Street light pole
Solar Street light pole is made of Q235 steel rolled pole, the whole hot dip galvanized treatment, hot galvanized anti-rust and anti-corrosion ability is strong, so at least to ensure 15 life.
4、Solar led street light Controller
General controller waterproof sealing grade is high, the normal use of a 10-15 years is no problem.
5、Solar led street light Battery
Solar street lights are currently mainly used in the battery is a gel maintenance-free battery and lithium batteries. Gel battery life normal 2 to 3 years, lithium battery life normal in 5 to 8 years. In normal use, 3 to 5 years is the time to replace the battery, because by 3 years or 5 years, the actual capacity of the battery is much lower than the initial capacity, affecting the lighting effect.
In general, the key to the service life of solar street lights is the battery, when buying solar street lights, it is recommended that the battery should be configured to be larger, to develop the life of the battery is his cyclic discharge life, complete discharge is about 500 to 800 times.
If the capacity of the battery is only enough to discharge every day, then the battery is easily damaged, but the capacity of the battery is several times the daily discharge, that means a few days to have a cycle, which greatly increases the life of the battery, and the capacity of the battery is several times the daily discharge, is to ensure that the number of consecutive rainy days is longer.
The service life of solar street lights also lies in the usual necessary maintenance, in the early stages of installation, to strictly follow the construction standards to do, in the configuration is also as reasonable as possible with, increase the capacity of the battery, so as to extend the life of solar street lights.
The current 8 year non-replacement battery has in fact been such a product, the battery used in our solar street lights is designed not to be replaced for 8 years. Let’s put it this way, there is a lithium iron battery with a cycle count of 2,000 cycles, which means no replacement within 5 years,
Our new German designed solar street light has been on the market since 2008, according to all the statistics conducted worldwide the proportion of bad batteries after use is less than 0.5% (no need to replace)
The fact that the batteries in our products are not replaced within 5 years is very normal and a fact, plus our new invention of a battery technology patent (a technology to extend the life of the battery) in 2012 on the basis of which the life of the design is 8 years without replacement.
