Residential solar batteries are created to hold excess solar energy that is harvested via solar panels placed on houses. They grant homeowners the ability to store energy until needed, which can be during low sunlight hours or nighttime. This decreases the need to rely on the power grid. Residential lithium-ion batteries are becoming increasingly popular because they have a long lifespan, energy density, require little maintenance, and are low upkeep. Furthermore, these batteries can unify with the home Energy management system, which allows users to monitor, control energy usage, and cut down on energy expenses.
