Solar + Storage
Solar plus storage for flexible use of solar generation
Pairing solar PV with battery storage transforms intermittent generation into dispatchable power. Store surplus solar energy for evening use, backup power, and demand management, maximising ROI on your solar investment.

Excess generation charges the battery system
Stored energy powers loads after sunset or during clouds
Smart controls optimise self-consumption vs export
Battery provides backup power during grid outages

Solar-to-Storage Ratio
80-95%
Self-Consumption
4-12 hours
Backup Duration
20+ years
System Life
Solar + Storage - Deployment Case Study
A commercial warehouse with a 200 kWp solar array was exporting 55% of generation at low feed-in tariff rates while importing expensive grid power in the evening.
A 400 kWh BESS was added to capture daytime solar surplus and discharge during evening peak consumption periods.
- Self-consumption increased from 45% to 91%. Annual electricity savings increased by $54,000. Payback on the BESS addition achieved in 4.2 years.
Plan your solar plus storage system
Start with solar generation and site demand measured across the same periods. Then identify surplus production, evening loads and export limits. Solar plus storage sizing should account for conversion losses, usable battery capacity and any energy reserved for backup. Existing inverter and connection details also influence the integration approach.
Compare BX commercial battery systems or discuss your site requirements. For background, see the U.S. Department of Energy’s solar energy and storage basics.
