69.16 kWp SolarEdge rooftop solar for Pyronix Ltd, Rotherham

The challenge

Pyronix Ltd’s roof faces south at a shallow 5° pitch, which is good for solar, but that side of the building is overlooked by a large aerial mast and a taller neighbouring building. Both cast shade across parts of the array during the day, and on a standard string system one shaded panel can drag down the output of the whole string. The roof had also just been replaced with insulated trapezoidal panels, so the fixings needed to suit that roof without compromising it.

Our solution

• Module-level optimisation. We designed the system around SolarEdge, with one power optimiser for every pair of panels (76 optimisers for 152 panels). Each pair works at its own best output, so shade on one part of the roof doesn’t pull down the rest. The design allowed for module-level shading losses of 6.44%.
• High-yield panels. 152 JA Solar 455 W N-type bifacial double-glass panels give 69.16 kWp.
• One three-phase inverter. A SolarEdge SE50K Synergy inverter (a 50 kW Synergy Manager with two 25 kW units) converts the power for the site.
• The right fixing for a new roof. Renusol MetaSole+ is a low-profile, rail-free bracket made to fix directly onto trapezoidal roof sheets like Pyronix Ltd’s new insulated roof.

The results

The system was commissioned in June 2026 and is now registered on SolarEdge monitoring. The design estimates around 59,155 kWh a year (est.), with about 39,271 kWh of that used on site (est.) and the rest exported to the grid.
