Chichester’s centre inside the walls is a conservation area with a high share of listed buildings, so solar there means rear slopes, all-black panels and a conversation with Chichester District Council before any quote. The estates around the ring road, Summersdale, Parklands and Whyke, are post-war and modern houses with simple roofs. South of the city the Manhood peninsula, Selsey and Bognor Regis are flat, sunny and full of bungalows, which suit a modest system and, for households at home all day, air conditioning in the summer.
The villages north of the A27 are inside the South Downs National Park, which has its own planning authority; the survey confirms which rules apply to your address.
