The coast from Christchurch to Weymouth gets around 950 kWh per kWp a year (PVGIS). Housing changes over short distances. Winton and Southbourne have 1930s semis, and Ferndown, Verwood and Highcliffe have many bungalows. There are large detached houses around Canford Cliffs and Wimborne, and newer homes at Poundbury and on the edges of Blandford. Near Poole Harbour and the seafront, salt air means coastal-rated fixings and inverters kept indoors where possible. Each roof has a different right answer, which is why the survey comes first.
Planning goes through BCP Council for Bournemouth, Christchurch and Poole, and Dorset Council for the rest of the county. The Dorset and Cranborne Chase National Landscapes cover much of the county, and the Jurassic Coast is a World Heritage Site. SSEN is the network operator for most of Dorset. West of Dorchester, many villages are on long rural lines that lose power in winter storms, where a battery with backup is worth asking about. Swanage and Purbeck, Shaftesbury, Sherborne, Bridport and Lyme Regis are all inside the area we cover.
