What is a solar storage battery?

A solar storage battery stores excess energy generated by solar panels for later use. When solar panels aren't producing electricity like at night or during cloudy days, the stored energy in the battery can be used to power homes. This enhances the self-sufficiency of a solar energy system, reduces reliance on the grid, and ensures a consistent power supply even when the sun isn't shining.
