Commercial Solar & Battery Solutions
Whether your business already has solar or is planning a new solar and battery system, the right solution starts with understanding your electricity usage, tariffs, solar generation and site requirements.
Existing Solar + Battery Storage
Already have commercial solar? We assess your existing system, electricity usage, tariffs, site loads and electrical infrastructure to determine suitable battery storage options and how they can be integrated with your existing system.
New Commercial Solar + Battery Systems
Planning a new system? We design solar and battery together around your site loads, operating hours, roof space, electrical infrastructure, tariffs and future energy requirements.
Why Install a Commercial Battery?
Commercial battery storage can help businesses use more of their solar generation and manage how and when electricity is drawn from the grid.
Use More Solar Energy
Store excess daytime solar generation for use when your business needs it.
Manage Peak Electricity Use
Battery storage may help reduce grid demand during higher-cost periods, depending on your electricity tariff and usage profile.
Improve Energy Flexibility
Store energy when conditions are favourable and use it when electricity costs or site demand are higher.
Prepare for Future Energy Needs
Battery storage can support changing business loads, EV charging and future electrification.
Commercial Battery Applications
Commercial battery storage can support different business energy needs depending on electricity usage, solar generation, tariffs and future site requirements.
Solar Self-Consumption
Store excess daytime solar generation for use when site demand is higher or solar generation is lower.
Peak Demand Management
Battery storage may help manage peak grid demand depending on the site’s electricity usage and tariff structure.
EV Charging & Electrification
Support future EV charging, equipment upgrades and increasing electrical loads as part of a broader energy strategy.
Energy Resilience & Flexibility
Battery storage can provide greater flexibility in how a business stores and uses electricity throughout the day.

Choosing the Right Battery for Your Business
Commercial battery sizing depends on more than solar capacity. Electricity usage, operating hours, tariffs, peak demand and future energy requirements all need to be considered.
Site Energy Use
How much electricity the site uses, when it is used and when peak demand occurs.
Existing Solar & Electrical Infrastructure
Existing solar, electrical supply and switchboard capacity can influence suitable battery options.
Electricity Tariffs
Usage rates, time-of-use periods and demand charges can influence battery operation and value.
Future Energy Loads
Future EV charging, equipment upgrades and business growth can influence system design.
