Horsham sits in the central belt of West Sussex on the edge of the High Weald, with the South Downs to the south and the M23 corridor running north to Gatwick and London. The town typically records around 1,600–1,700 hours of sunshine a year — comfortably above the UK average — which translates into reliable, productive output from a properly designed solar PV system.
Horsham District Council has been an active partner in regional sustainability initiatives, including running a Solar Together group-buying scheme to make renewable energy more affordable for residents. The town’s combination of strong local government engagement and a large body of newer-build housing has made Horsham one of West Sussex’s more active areas for residential solar adoption.
Horsham has a particularly varied housing stock. The older streets around the Causeway and East Street include listed buildings and conservation area constraints, but the wider town is dominated by post-war estates, 1960s and 1970s family housing, and a significant body of new-build properties at Highwood, Kilnwood Vale, North Horsham and Broadbridge Heath. These newer developments often feature simple roof geometries and minimal shading, making installation straightforward.
Horsham District Council has shown a clear commitment to supporting renewable energy adoption across the district, including the Solar Together scheme. For the majority of Horsham homes, planning permission is not required for roof-mounted solar panels under permitted development rights. Exceptions apply to listed buildings, properties in conservation areas (particularly the Causeway, Denne Road and parts of North Street), and certain larger installations.
