Going solar comes with plenty of benefits, but one homeowner took to Reddit to share their biggest regret.

In a post shared on r/solar, the original poster talked about how their decision made them wish they had installed extra panels or gone with larger ones when they switched to solar.

“Hindsight is 20/20, but after adding batteries, I regret not getting another 2-3 panels when I had the system installed,” the OP wrote.

Other Reddit users were quick to share some of their own experiences with solar.

“Honestly, get as much as you can. Things change and you’ll probably need more electricity in the future than you do today. I needed 20 panels to cover usage, so I got 65,” a user chimed in.

The Redditors may have a point. A new study published in Nature Energy found that 60% of U.S. households could save an average of 15% on electricity costs by using solar battery systems, Stanford Energy reported.

Solar could also help 63% of households access alternative power sources during local or regional outages, which are worsened by extreme weather events and may become more frequent.
