How long do solar batteries last?

Lead-acid batteries, a more affordable option, generally last 3 to 7 years in solar setups. In contrast, lithium-ion batteries, though pricier upfront, often provide 10 to 15 years of reliable service. Factors such as discharge depth, charge cycles, environmental conditions, and maintenance all affect how long a solar battery lasts.

How long do solar panels last?

Solar panels will last between 20 - 30 years, whereas a lithium-ion solar battery will last up to 15 years. There are two key takeaways from this: firstly, it emphasises the importance of choosing a durable, high-quality battery with a high cycle life and a history of reliability; secondly, the installation process matters.

What is the longest lasting solar battery?

Among the various options available, lithium-ion batteries, particularly Lithium Iron Phosphate (LiFePO4), generally stand out as the longest-lasting solar battery type. LiFePO4 batteries typically offer a lifespan of 10-15 years or more, significantly outperforming traditional lead-acid batteries.

How long do lithium ion batteries last?

Lead-acid batteries have a cycle life of between 1500 - 3000 cycles, equating to around three to five years. Lithium-ion batteries have come to dominate the market. Cycle lives vary, but quality solar lithium-ion batteries far exceed the lifespan of lead-acid batteries.

Which battery is best for solar backup?

Let’s compare with the other batteries below. Bottom Line: Lead-acid batteries are the cheapest option for solar backup, but suffer from shorter lifespan and low DoD. Estimated Lifespan: 10 to 15 years
