In 2021, a new solar project was installed every 60 seconds in the U.S. With so much solar being installed every day, the energy grid is beginning to look a lot more sustainable.  Going solar isn’t a surefire way to avoid blackouts and brownouts, though. In fact, if your solar energy system is connected to the electrical grid, your utility requires you to have a safety disconnect to protect workers during power outages. That means you’ll lose power like everyone else, unless you also install solar battery storage.  Our guide covers the different types of batteries, how they work, and how much solar batteries cost. We compare solar batteries and generators, and look at the incentives available offered by states, utilities, and other entities for solar storage.
