What Wolverhampton homeowners actually pay
Wolverhampton's housing mix is wide — Victorian terraces in the centre, large inter-war semis in Penn and Tettenhall, and 1960s housing in Bilston and Wednesfield. Most installs are unrestricted; the headline exceptions are the Tettenhall and Compton conservation areas. A typical 4 kWp install lands £4,400–£5,800 and generates around 3,660 kWh per year, with payback inside 9–10 years. Roof orientation across the inter-war semis is generally favourable.
Tettenhall and Compton conservation areas restrict front-elevation panels.
