Solar batteries allow you to use more of your solar energy even when the sun isn’t shining. They take your excess energy from the day before, and store it for you to use later at night, during blackouts, and on cloudy days – helping you reduce your reliance on the grid, and protecting you from higher electricity prices and reduction in feed-in tariffs.
