The lifespan of a solar battery is primarily determined by its use cycles. The general range for a solar battery's useful lifespan is between 5 and 15 years.
Lead-acid batteries have a shorter lifespan, and lower depth of discharge (DoD) compared to lithium-ion batteries.
When it comes to home energy storage systems, lithium-ion batteries are lighter, more compact, and have a longer lifespan with higher depth of discharge (DoD) than lead-acid batteries
What Are The Factors That Affect The Lifespan Of Solar Batteries?
1. Solar Battery Usage:
The life expectancy of a solar battery is mostly determined by its usage cycles. Most solar batteries are generally deep-cycle batteries, which allows them to discharge up to 80% of their stored energy before recharging.
2. Solar Battery Temperature:
A battery attains higher chemical activity when kept under high temperatures. This makes the solar batteries less efficient in colder climates. However, the cyclic life of a battery decreases with the increase in temperature.
3. Cyclic Life Of Solar Batteries
The solar batterys lifespan can be determined by its cyclic life or the number of use cycles it has performed.
For example, a flooded lead-acid battery can be expected to provide 300 to 700 cycles. A gel battery can give you 500 to 500 cycles. While lithium batteries can provide 2000 to 2000 cycles.
How to improve the Solar Battery Lifespan?
- Do not leave solar batteries uncharged for a very long time as it can damage the battery.
- Using right type of Solar battery is very important. Lithium batteries are more recommended to use because they can last up to 8 years. They can be easily replaced if they are not functioning properly due to the special waterproof plug and connectors used.
