Our largest roof: 360 panels keeping a refrigerated warehouse cold on sunshine.
The brief
Refrigeration runs around the clock, with the highest load on warm afternoons when the sun is up.
What we fitted
Three hundred and sixty panels across two roofs, three 50 kW inverters and a 100 kWh battery for overnight cooling.
Twelve months on
The site now covers about 42% of its annual demand from the roof. Payback is tracking just under five years.

In their words
Cold storage peaks on sunny afternoons, which is exactly when the roof peaks. The numbers on the plate have held for a full year.
