Is The SunPower SunVault or Tesla Powerwall the Better Solar Battery?

If you are concerned about power outages, you might be interested in getting a battery with your solar system. Solar batteries provide storage for excess electricity produced by a solar array. This stored energy allows you to keep your home powered even when the solar panels are not producing energy.

Two of the most popular solar batteries right now are the Tesla Powerwall and the SunPower SunVault. We are here to help if you are struggling to choose which one would be the right fit for you!
