FAQ
Felicity ESS Battery Questions
No, solar panels work perfectly without a battery. However, adding battery storage lets you use your solar energy at night and during power outages. Batteries are increasingly popular as their prices have dropped significantly in recent years.
Most modern solar batteries come with 10-year warranties and are designed to last 15+ years. The Tesla Powerwall, BYD Battery-Box and Sungrow batteries we install all carry strong manufacturer warranties.
