How do solar batteries work? The energy produced by solar panels is stored in solar batteries. They are a crucial part of a solar energy system because they enable the storage of extra energy generated by the solar panels during the day to be used as a backup power source at night or during periods of low sunlight. In order to power homes and businesses, solar batteries convert the direct current (DC) electricity produced by solar panels into alternating current (AC). Users can lessen their reliance on electricity from the grid, increase their energy independence, and lower their energy costs by storing excess energy in a solar battery.
