4-bed Performance
system
A four-bedroom detached home on the Performance tier. System sized against 12 months of actual consumption data. South-facing roof at 35° pitch. One EV on site. Annual saving accounts for current export tariff, avoided import and EV running cost reduction.

INT-01
EV charging
Tariff-aware charging integrated with solar generation and battery state. Charges from solar surplus first, grid off-peak second. No manual management required. Whole-day running cost effectively eliminated on Performance and Premium tiers.
INT-02
MVHR
Mechanical ventilation with heat recovery. Recovers up to 90% of heat from outgoing air, maintains fresh air quality throughout and eliminates condensation. Increasingly standard on high-performance retrofits and new builds.
INT-03
Hot water & heating
Surplus solar diverted to immersion heater or heat pump pre-heat instead of exporting at low tariff rates. One of the highest-value uses of excess generation. Integrated with battery scheduling so storage is prioritised correctly.
