Battery backup
What a battery does between 6 and 9 pm, and what it does when the power goes out.
Short answer: a battery earns its place in Las Vegas in two situations. The first is the summer evening: on NV Energy's time of use plan, power from 6:01 to 9 pm between June and September costs about six and a half times the off peak rate, and the sun is going down just as that window opens. The second is an outage, when a battery keeps the circuits you chose running with no generator to start and no fuel to store. On the standard flat rate there is no evening window, so a battery has to make its case on backup and on the daily demand charge. NV Energy's residential storage incentive has been closed to new applications since June 2023, so any quote has to stand on its own arithmetic. Start with the evening window, then sizing, then adding a battery to panels you already own.
