Energy storage batteries store solar energy

A solar battery's main function is to store excess electricity generated by your solar panels1. Solar power systems with battery storage allow for more self-reliance, as unused power generated by the system is stored in a battery and can be used as needed2. A solar battery's main function is to store excess electricity generated by your solar panels. If you have a solar battery installed, extra electricity from your solar panels goes into storage so you can use that energy later. In contrast, a solar power system that includes battery storage allows the system to be more self-reliant. Unused power generated by the system is stored in a battery and can then be used as needed, reducing dependence on the grid and providing a continuous power supply even during outages.
