One California homeowner with a great deal on their existing solar panel setup decided to improve upon it with a battery backup and shared their experience on the r/solar subreddit.

"I decided to add a Franklin WH a2 battery on my 6 year old solar system," said the original poster. "I'll share more once I get a better sense of the net savings, but I'm optimistic it'll make a solid."

According to the original poster, they intentionally left their air conditioning off the battery system but hooked up everything else in their house so that they would have backup power in the event of an outage. "The initial reason that triggered my research was because I wanted a clean/quiet emergency back-up option to all my critical home power needs. We typically lose power 2-3 times a year due to high winds or other reasons in my area," they said.Β 

This homeowner's decision is a smart one. The only thing better than solar panels for saving money on home energy and improving resilience is a solar panel setup with a battery backup. In addition to reducing your planet-overheating pollution, a solar system generates energy essentially for free whenever the sun is up.
