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.
