Solar + batteries at home can provide backup power during disasters

Lights went out as Hurricane Fiona devastated areas from the Caribbean to Canada, and Hurricane Ian has done the same. Hurricanes, along with other natural disasters like wildfires and winter storms, can leave people without access to electricity.
However, new research out of the Lawrence Berkeley National Laboratory suggests that added solar capacity, paired with batteries, can help address this problem. The study makes use of historic long-term power outages (caused by disasters) and models the performance of behind-the-meter solar and energy storage systems functioning as a kind of backup source of power during long-term power interruptions.
Behind-the-meter refers to solar systems that are installed on a customer's residence-on the customer side of the electricity meter. The more common term for this is roof-top solar," according to Galen Barbose, a research scientist with the Lawrence Berkeley National Laboratory and one of the paper's authors. It's more customer-sided solar," he told Ars.
