A solar battery is a device that is charged by a connected solar system and stores energy as a backup for consuming later. Users can consume the stored electricity after sundown, during peak energy demands, or during a power outage. Using a solar battery can help users to reduce the amount of electricity they would normally buy during peak hours. The battery can store the extra energy produced from solar panels during the day to avoid using electricity at. The capacity of a battery is about the total amount of electricity it can store in terms of kilowatt-hours (kWh). The power rating, on the other hand, is a battery's electricity delivery at one time. The life of solar batteries naturally degrades over time, and this is why it is crucial to know the expected lifespan of the solar battery before.
