Your solar battery charges from the grid due to insufficient solar generation. Insufficient sunlight, panel shading, or system capacity issues can lead to reliance on the grid for charging.
Alternatively, your system may be set to charge during cheaper, off-peak hours to reduce costs. So, if your energy tarriff is half as cheap at night, you can charge then and use the energy during the day instead. All perfectly legal, and a whole lot cheaper!
Hi, I'm Emily Shepherd and I create easy-to-follow online content about solar power and renewable energy. I first got interested in solar after working for a solar panel installation company, and I enjoy helping people understand how it all works and what it could mean for their home or business. I care about the earth, and I like sharing practical tips for using cleaner energy in everyday life. When I’m not writing, I’m keeping up with the latest solar updates and looking for simple ways to make renewable energy more accessible.
