This is both obvious but also exciting. Long ago, when I was Director of a renewable energy business, we saw home-owners and businesses that installed solar panels, changing their habits to put on washing machines on sunny days, and maximise their self consumption. Now of course that is much easier with home energy storage, as provided by Hyperion clients like sonnen. With the rapid rise of EV's, and home charging, this solution saves a lot of money, but also helps solve grid scale issues.
