Case study · Home with annexe
20 panels, battery, heat pumps and EV charging
A joined-up energy system for a property with two air source heat pumps serving heating and hot water, significant electricity demand and EV charging.
The completed solar PV array, air source heat pump and Zappi EV charger.
The property
A high-demand home needing one coordinated solution.
The home and annexe used approximately 9,200 kWh per year, with two air source heat pumps providing heating and hot water. Solar, storage and vehicle charging were considered together rather than as separate projects.
The solution
- 20 solar PV panels
- 13 kWh Tesla Powerwall battery
- Two air source heat pumps serving heating and hot water
- Zappi EV charger incorporated into the energy plan
- System designed around the property’s heat-pump demand
Bill reductions and lifetime savings depend on usage, tariffs, energy prices, weather and system performance. We produce a tailored illustration for every property.
