Thompson Street Barry Flats.

This project at Thompson Street Barry Flats (CF63 4JL) represents a strategically designed multi-residential solar PV installation, engineered to deliver consistent energy generation while maintaining full compliance with UK electrical and structural standards. The system integrates high-efficiency Jinko Tiger 410W N-Type solar panels, paired with a Growatt MOD 4000 TL3-X three-phase inverter, ensuring optimal energy conversion and long-term operational reliability.

Installed across a flat roofing structure, the system utilises a carefully calculated low tilt angle of 15 degrees, optimised for the geographical solar irradiance profile of South Wales. The array configuration is split across two independent MPPT inputs, each handling a string of five panels, allowing for improved energy harvesting efficiency and resilience against potential performance variances.

From a performance standpoint, the system is expected to generate approximately 3,662 kWh annually, providing a significant contribution toward reducing grid dependency for the residential flats. The absence of shading constraints ensures maximum solar exposure throughout the year, while the electrical design maintains voltage and current parameters well within inverter operating thresholds.

Structurally, the installation demonstrates a minimal load impact, increasing roof loading by less than 1%, confirming suitability for retrofit applications without compromising building integrity. The use of console mounting systems further supports a non-invasive installation approach, particularly suited for flat roof environments.

This project highlights the scalability of solar PV solutions within multi-dwelling residential developments, enabling property owners and housing operators to reduce operational energy costs, improve EPC ratings, and contribute toward long-term sustainability targets.
