Sixty-eight kilowatts, on roofs you can drive past

Twelve panels on a mid-terrace with a shaded eastern gable, and an honest note in the survey that twenty-nine percent self-consumption is what a working couple should expect.

Thirty-five panels over a workshop and vehicle bay that draws hardest between nine and four, which is the shape of load solar is actually good at.

Twenty-six panels split across a barn roof and the south face of the farmhouse, sized around a milking parlour that runs through the middle of the day.

Nine panels on a listed slate roof, in-roof mounted so the array sits flush with the slate rather than standing proud of it.

A landlord supply feeding six flats, a lift and a communal corridor. High daytime load is what makes a system this size worth its cost.

Eighteen panels on the long south elevation, sized around an air-source heat pump that carries most of the winter load.
