No, you don’t need to install a solar battery in Surprise. Solar panels can operate and lower your electricity bill even without a battery. However, a solar battery might be a worthwhile investment in some cases. A battery can provide backup power and priceless peace of mind in places with prolonged grid blackouts or extreme weather events. If your utility doesn’t have full retail net metering or uses time-of-use rates, a battery can also save you more money on your electricity bill. Ask your solar company about the benefits of having a solar battery in Surprise and if the upfront cost is worth the investment.
