The average lifespan of residential energy storage batteries varies widely depending on the type of battery and usage patterns. Most solar batteries on the market today last between 5 and 15 years.
- Lithium-ion batteries, which are common in residential solar systems, typically last between 10 and 15 years. They are more expensive upfront but offer better longevity and efficiency compared to other types.
- Lead-acid batteries generally last 3 to 7 years due to frequent cycling and lower durability.
- Lithium iron phosphate (LFP) batteries, a specific type of lithium-ion chemistry, can last even longer, typically 15 to 20 years, and they endure 6,000 to 10,000 cycles.
Factors that affect the lifespan of solar batteries include:
- Number of charging cycles: Each cycle reduces the battery’s capacity to hold a charge.
- Depth of discharge: Deeply discharging a battery regularly can shorten its lifespan.
- Environmental conditions: Extreme temperatures can degrade battery performance and longevity.
- Maintenance and usage patterns: Regular maintenance and avoiding deep discharges help extend the battery’s life.
