A solar battery, also known as a solar energy storage system or solar battery storage, is a device that stores the electricity generated by solar panels for later use. It allows homeowners, businesses, and communities to store excess solar energy during periods of sunlight and use it during times when sunlight is not available, such as at night or during cloudy weather. Here's how solar batteries work and some of their key features: Energy Storage: Solar batteries store excess electricity generated by solar panels during peak sunlight hours. Instead of feeding this excess electricity back into the grid, it is stored in the battery for later use. DC to AC Conversion: Solar batteries typically store electricity in direct current (DC) form. When the stored electricity is needed, it is converted into alternating current (AC) through an inverter, making it compatible with household appliances and the electrical grid.
