The project
This Stockport household wanted to power their home and their EV from the same source. We installed a 4.7kW Longi array paired with an 11.52kWh FOX ESS battery and a Zappi charger — letting them charge the car from surplus solar and run the home from stored energy after dark. Electricity bills dropped from £1,500 to under £250 per year.
