Local context

Solar in St Albans and central Hertfordshire: quick guide.

The AL districts cover a cluster of Hertfordshire towns, from a medieval cathedral city to a planned garden city, and that range shapes a solar install:

• The historic St Albans core. The city has a large conservation area with many listed timber-framed and Georgian buildings around the cathedral and Roman remains, so panels on prominent roofs there need consent and careful siting.
• Edwardian and Victorian Harpenden. Harpenden and the older St Albans suburbs have period villas with simple pitches that suit panels, subject to any conservation status.
• Welwyn Garden City and Hatfield. The garden city and Hatfield add planned interwar and postwar housing, plus newer estates, with clear, well-oriented roof space.
• East or west still works. A south pitch does best, but an east or west roof spreads output across the day and performs well across the area.
• Get a survey. An installer survey confirms roof direction, condition and the right fixings before you commit.
