Solar energy storage refers to the technology that captures and holds energy generated from the sun for later use. This is typically achieved through devices like batteries, which store excess electricity produced by solar panels during sunny periods. When the sun isn't shining, stored energy can be used to power homes and businesses, ensuring a consistent energy supply. The main benefit of solar energy storage is its ability to enhance the reliability of solar power. By storing energy, users can reduce their dependence on the grid and lower electricity costs. This technology supports the transition to renewable energy sources, contributing to a more sustainable future.
