Winchburgh Waste Water Treatment Works

Project Outline

R&A Group were appointed to design, supply, install and commission a 53kW Solar PV system at Winchburgh Waste Water Treatment Works as part of the client’s ongoing investment in renewable energy infrastructure. The project forms part of wider efforts within the water utility sector to support Scotland’s Net Zero targets by reducing carbon emissions and operational grid demand.

The works included a full design review, grid application, scaffold installation and electrical containment. A remote monitoring system was incorporated to provide real-time performance data, including module-level oversight and arc fault protection with rapid shutdown capability.

A trapezoidal roof mounting system was installed to support 96 PV panels, paired with a SolarEdge inverter and optimiser technology to maximise generation efficiency and system visibility. The installation was delivered using Renusol mounting equipment and SolarEdge components to ensure long-term reliability.

The main installation works took place between September and October 2023, with careful coordination to maintain site safety and minimise disruption to wider operations.

Project Outcome

The 53kW Solar PV system was successfully installed, tested and commissioned, and is now operating in line with expected performance levels. The system generates clean renewable electricity for the facility and provides measurable reductions in grid consumption.

By delivering this installation, R&A Group have supported the client in contributing to Scotland’s Net Zero objectives, with the system expected to avoid more than 8 tonnes of CO₂ emissions annually.

The project demonstrates R&A Group’s capability in delivering technically robust, specification-led solar PV systems for the water utility sector, providing long-term environmental and operational benefits.
