4.4 kW + Tesla Powerwall 3 — Detached Home in Bury

Family of four wanted to cut their £2,400/year energy bill and have outage backup for the home office.

System size

4.4 kWp

Battery

Tesla Powerwall 3 (13.5 kWh)

Annual saving

£1,420/year

Payback

7.1 years

The Challenge

Roof had a chimney shading the south face for 3 hours mid-morning. Octopus Go tariff already in use for car charging at night.

Our Solution

4.4 kWp on south-facing roof with optimisers on the 4 panels affected by chimney shading. Powerwall 3 with whole-home backup gateway for outages. Octopus Flux configuration replacing Go tariff.

The Result

£1,420 first-year saving (60% of pre-install bill). Storm Watch backed up the home through 2 power cuts in November 2025. Still on track for predicted 7.1 yr payback.
