How do you calculate how much equipment we need?
We use a bespoke modelling tool that considers your building’s energy consumption, roof orientation, shading, available space and projected usage patterns. This allows us to size the system to maximise financial and carbon savings.
Is it possible to install just a battery without solar panels?
Not under the current DEAL scheme. Batteries work best when paired with onsite solar generation, which improves payback and ensures consistently low-cost electricity. You can, however, add batteries to an existing PV system. In these cases, legal transfer
documents would be required.
What is an island mode battery?
An island mode (or backup) battery can power key circuits in your building during a power cut. This allows essential services, such as lighting, communications, or heating, to continue operating even when the grid is down.
We are a designated warm hub for power outages - do we need additional batteries?
Possibly. If your building must remain operational during outages, we can design the system with additional battery capacity or specify island mode capability. This will be assessed during your feasibility study.
What happens if our electricity demand increases? Can the kit be expanded?
Yes, systems can be expanded. Additional panels, batteries, EV charge points or other technologies can be integrated later if the cooperative and site agree that the upgrade is technically feasible.
Can we add other technologies such as Air Source Heat Pumps, EV chargers or infrared heating panels?
Yes. While DEAL doesn’t currently offer these on the scheme, technologies such as air source heat pumps, EV chargers and infrared heating panels can be integrated into your wider building energy plan. We can provide guidance on sequencing and any electrical upgrades required.
