The system
Ten panels on the roof generating 4kW, paired with a GivEnergy 9.5kWh battery. The battery was sized to cover the household's typical evening usage — the period when solar generation has stopped but electricity demand is highest. The system was designed to maximise self-consumption rather than export.
The result
The EPC rating improved from D to B. The household now covers the majority of its electricity needs from solar and stored solar. The installation was completed in a single day, with no disruption to the neighbouring terraced properties.
Why it matters
Terraced properties can be harder to work on than detached houses, but the roof area is often sufficient for a well-sized system. A single-day installation matters when you share walls with neighbours.
