Why Add a Battery to Solar?
Store Solar for Night Use
Batteries store excess daytime solar electricity for use in the evening when panels stop generating.
Increase Self-Consumption to 70%+
Without a battery, you use around 40% of solar generation. A battery raises this to 70–80%.
Time-of-Use Tariff Savings
Charge your battery on cheap overnight rates and use stored power during expensive peak hours.
Backup Power
Some battery systems provide emergency backup power during grid outages.
