6 FAQs about [How big a solar panel does a 35a lithium battery need]

Can a 120W solar panel charge a 35ah battery?

A 35ah battery may have a capacity of 420 watts, but due to the depth of discharge (DO) in lead acid batteries, it can only be charged with 210 watts at a time. All lead acid batteries (FLA, AGM, gel) cannot be used to their full capacity, and must be recharged when the capacity drops to 50%. If you use a 120W solar panel, the charge time will be a bit faster.
