Battery BackupPower When You Need It Most
Why Battery Backup Matters for Homes and Businesses
Batteries store excess daytime solar energy for use after sunset, during storms, outages, or emergencies. Unused energy may also support net-metering credits.
You Need It
Save Stored Solar Energy for Peak Hours
With a battery system, you can store extra solar energy produced during the day and use it after sunset, during peak-rate hours, or when the power goes out. You may also be able to send unused energy back to the grid for additional net-metering credits.
