Harumi Fuji McClure and her husband live in a nice, two-story house in Morgan Hill south of San Jose. It gets pretty hot there in the summers, so they have a large swimming pool and air-conditioning in the whole house. But her electricity bill isn’t high: it’s negative five dollars a month.
Yes, Fuji McClure actually gets money back. This is because of the solar panels and the battery storage system she uses to power the house.
Fuji McClure walks into the garage to show me her battery system. It’s a gray metal box, about the size of a hotel minibar, tucked away in a corner. Fuji McClure says most of the time, she and her husband don’t even realize the battery is there.
