Case studies
Named North East installs — real KPIs, real properties
4 recent residential and commercial installs across 4 North East towns. Each case study includes the actual system specification, headline result, customer first name (anonymised surname) and supplementary KPIs.
Harraton, Washington — 4.2 kWp solar + 5 kWh battery on 1970s semi
A south-east-facing 1970s semi in Harraton, Washington. The owner had been monitoring electricity prices for 18 months and wanted both bill reduction and partial energy independence. We sized a 10-panel 4.2 kWp system with a 5 kWh battery to maximise self-consumption.
Result
64% lower electricity bills
Sunderland — Tesla Powerwall 3 + Zappi EV charger on 4-bed detached
A Tesla Powerwall 3 + Zappi v2 charger retrofit onto a 2008-build Sunderland detached. The owner already had 4 kWp solar from 2022 but wanted battery storage to capture more daytime export and EV smart-charging to maximise the Octopus Intelligent Go tariff.
Result
92% self-consumption + 7p/kWh EV fuel cost
Cramlington — 48 kWp solar PV array for primary school
A 48 kWp commercial solar PV array installed at a Cramlington primary school. PSDS Round 4 funded 60% of capital. Annual generation 42,000 kWh — covering 36% of school electricity demand. Phased over Easter holidays to avoid term-time disruption.
Result
£8,400/yr electricity bill saving + 8 tonnes CO₂

3× Ohme 22 kW three-phase EV chargers installed at a building merchant's Consett yard. Northern Powergrid three-phase supply upgrade negotiated; OZEV Workplace Charging Scheme funded £1,050 (3× £350 per socket). Fleet of 6 Ford Transits transitioning to EV over 2 years.
Result
£4,800/yr fleet fuel cost saved per EV
