The project
This Altrincham family were burning through 8,000 kWh of grid electricity a year — costing them nearly £2,500. We designed a 12.5kW Sigenergy-powered system to maximise self-consumption, store surplus daytime generation and slash their reliance on the grid. The result: electricity bills under £100 a year and a 4.5-year payback.
