FAQs 6

How long do solar batteries last?

Solar batteries don’t last as long as solar panels because they degrade more quickly. A solar panel’s main components – aluminium, glass, plastic, and silicon – will all outlast the panel itself, and can be recycled once it’s dismantled. A battery’s components simply last for less time – though as we’ve covered above, the technology is improving.

How long do solar panels last?

After all, with solar panels typically lasting 30-40 years, you’ll want to know how many battery systems you’ll have to buy to match your panels’ lifespan. We’ll run through the average lifespan of different types of solar batteries, the factors that contribute to these figures, and how you can extend your battery’s lifespan.

How long does a battery last?

Lead-acid batteries (flooded or sealed): These are the most traditional type and also the shortest-lived, typically lasting 3 to 7 years. They’re more affordable upfront but require regular maintenance and don’t hold up as well over time. When people talk about battery lifespan, they’re often referring to “cycle life.”

How much electricity does a solar battery store?

The typical solar battery stores between 10 and 20 kilowatt-hours (kWh) of electricity, while the average home uses about 30 kWh per day. When you pair a battery with solar, you can recharge the battery as soon as the sun comes up in the morning, effectively allowing for indefinite backup. Explore your storage options on the EnergySage Marketplace.

How long do lead-acid batteries last?

Lead-acid batteries have a typical lifespan of three to seven years, with the flooded version lasting longer than the sealed model. And its life expectancy can drop even further if owners don’t keep up with lead-acid batteries’ more extensive maintenance needs.

How often should you run a solar battery?

Running too few or too many cycles can be detrimental to your battery’s lifespan. A single cycle per day is a normal rate for a household with solar panels, though if you're on one of the best export tariffs, check with your installer if it'd be more profitable to run two cycles.
