Why Add Battery Storage to Your Solar System?

Without storage, excess solar energy is exported to the grid at low rates. Battery storage lets you keep that energy for when you need it most.

Commercial Battery System Sizes

Commercial battery systems run from 50kWh to multi-MWh scale and are tailored to the site\'s energy profile and objectives.

How Battery Storage Works

Charge During Low Demand

Batteries charge from solar panels or cheap off-peak grid electricity.

Store Energy Efficiently

Modern lithium batteries retain 95%+ of stored energy with minimal degradation.

Discharge During Peak Times

Smart management systems automatically discharge during expensive peak periods.

Solar + Storage: The Perfect Combination

Combining solar panels with battery storage maximises the value of your investment. Without batteries, you might only use 30-40% of your solar generation directly. With storage, you can achieve 80-90% self-consumption.
