Hills run the show in Halifax. King Cross, Pellon, Skircoat Green, Boothtown and Ovenden all rise away from the centre in stone terraces, so one street can hold a south-facing row and a north-facing row. The south-facing stone-slate roofs take six to eight panels, once the installation team has checked the timbers underneath. Savile Park and the streets round the Akroydon model village (a conservation area) have bigger Victorian houses with several pitches, and one of them is usually good.
The flattest sites in the district are down in the valley bottom at Brighouse, Elland and Rastrick. Inter-war semis, post-war estates and new-build along the Calder make these the easiest jobs in Calderdale: 3.5 kW on a plain gable, a battery in the garage and everything done in a day. Climb to Lightcliffe, Hipperholme and Norwood Green and bigger stone semis and detached houses have room for 4 kW and a larger battery.
The upper valley is where you find the famous over-and-under terraces, in Sowerby Bridge, Mytholmroyd, Hebden Bridge and Todmorden. One home sits above another, built into the hillside, often under one steep pitch. Get the south side of the valley and the roof can be excellent. Sit in the shadow of the opposite hillside and winter sun can vanish for weeks. So we ask which side you are on before booking a survey.
