Gavin Smith – Solar Installation (2025)

6.6kW Solar PV System with Fox ESS Battery Storage

This 2025 installation in Rowlands Gill features a high-performance 6.6kW solar PV system paired with a Fox ESS hybrid inverter and ECS-series battery module. The system was engineered to maximise energy independence for a home-all-day occupancy pattern.

The AIKO Solar Neostar 2S 440W panels were split across two roof aspects to optimise yield, and Tigo optimisers were installed on four panels to mitigate shading losses. A new distribution board and full G99 approval were also completed as part of the installation.
