Our solutions

Solar energy works best when it’s intelligently stored and strategically deployed. Without energy storage, excess solar must be used in real time or exported to the grid. But with storage in place, surplus energy is saved for later, enabling your business to use more of what it generates, reduce reliance on fossil fuels and secure a more consistent, predictable energy supply. Energy storage also offers peace of mind. In the event of a grid outage, stored energy can provide backup power to keep essential operations running - helping your business stay productive.

Shift & Save: Energy storage as a financial strategy

At RenEnergy, we go beyond backup. Our Shift & Save energy arbitrage solution uses smart controls to store energy when it's cheap and dispatch it when it's expensive — turning your solar and storage into a financial asset.

Whether your system is new or already in place, Shift & Save unlocks greater ROI by aligning your energy use with tariff windows. The result? Strategic savings, faster payback, and greater resilience.

Why partner with RenEnergy?

We continuously track global innovations in energy storage — but our key differentiator is how we apply it. Our team has developed deep in-house expertise and proprietary modelling tools that tailor each solution to your tariff, load profile and operational goals.

Battery energy storage can be installed alongside solar PV or retrofitted into an existing solution. Either way, our process begins with a consultative, data-led assessment to ensure commercial viability and maximise long-term value.

Typical applications include

• Shift & Save energy arbitrage – charge from solar or low-cost grid supply, discharge during peak tariff periods

• Peak shaving – limit your draw during maximum demand periods

• Excess solar harvesting – capture and store surplus generation, especially in summer months

• Increased self-reliance – reduce exposure to grid instability and rising costs

• Diesel reduction or replacement – substitute expensive generator usage with clean stored energy

• Internal demand capacity increase – power expansion without new grid connection upgrades

• Onsite electric vehicle (EV) charging – power electric vehicle chargers for staff and visitors using your own solar and storage

If your business is already using solar – or thinking about it – you could be leaving significant value on the table. Our team will help you model the savings, define the business case, and deploy the right energy storage and charging solution to support your energy and sustainability goals.
