Battery Life for Photovoltaic Storage

Storage batteries for photovoltaic systems have lifespans that vary based on several factors, including battery type, usage conditions, and maintenance practices.
In general, lithium batteries, such as lithium iron phosphate (LiFePO4), have an expected lifespan of 10 to 15 years, while lead-acid batteries have an expected lifespan of about 5 to 10 years.
Temperature, the number of charge/discharge cycles, and regular maintenance are key factors that affect battery life.
Lithium batteries: These batteries tend to last longer than lead-acid batteries and have become the most popular choice for residential solar systems.
Lead-acid batteries: They have an expected lifespan of about 5 to 10 years.
To maximize battery life, it is important to reduce the number of deep charge/discharge cycles, keep the batteries at a moderate temperature, perform regular maintenance, and carefully monitor energy consumption.
Additionally, some manufacturers offer warranties on their products that cover a specific period of time or a number of charge/discharge cycles. For example, there is a Korean company that offers a 10-year warranty on the storage system.
Remember that the lifespan of storage batteries depends on several factors, and adopting proper management and maintenance practices can significantly help to extend it.
