Today, solar batteries have become a critical component of solar energy systems, because they store energy produced by solar panels and allow it to be used when the need arises. There exist different types of solar batteries. Among them are nickel-cadmium, lead-acid, and lithium-ion batteries. Each of these types has a unique lifespan and distinct features. In what follows, we discuss the lithium-ion solar battery lifespan, and the factors impacting this lifespan.
Lithium Battery Lifespan
While lead-acid and nickel-cadmium batteries have average lifespans of 5-10 years and 10-15 years respectively, the lithium battery lifespan is about 15-20 years. The variation depends on the quality of the battery and the manufacturing company. Apart from the relatively high lifespan, lithium-ion solar batteries have a low self-discharge rate and high energy density.
Factors Affecting Lithium Battery Lifespan
It is imperative to understand the factors affecting lithium battery lifespan in order to get the greatest value out of your investment.
Temperature
A notable factor that can affect the lifespan of such batteries is temperature. The performance of lithium-ion solar batteries is adversely affected by extreme temperatures. Extremely high temperatures can significantly increase the rate of chemical reactions within the battery, leading to evaporation of electrolytes. Extremely low temperatures, on the other hand, reduce the rate of chemical reaction, adversely affecting the capacity and lifespan of the battery.
Charge and Discharge Rate
Lithium battery lifespan can also be affected by the charge and discharge rate. Charging and discharging lithium batteries at a high rate can increase internal resistance and generate heat, potentially reducing battery lifespan. This is why at Felicity ESS, we strongly encourage you to use a compatible charger that charges your battery at the recommended rate. Our LUX-Y-48100HG01 15.3kWh 51.2 Voltage battery pack is compatible with most of the leading inverter brands, thus ensuring a lower risk of reduced internal resistance.
Battery Quality
The lithium battery lifespan can further be determined by the quality of the battery itself. Poorly-made, cheap batteries have a shorter lifespan and are prone to failure. This makes it critical to invest in a lithium battery from a reputable manufacturer. This will ensure you get a high-quality product with a longer lifespan and better overall performance. Our lithium ion solar batteries have impeccable protection measures such as the in-built smart Battery Management System, (BMS) a fuse, and a breaker to protect against potential risks and promote optimal battery performance. For instance, our LUX-X-48100LG01 5.12kWh 51.2 Voltage is a high-performance, ultra-durable lithium-ion battery pack that employs LiFePO4 technology, which is well-known for extending the battery life cycle.
Závěr
