Solar Panel Installation in Duporth

Duporth's south-facing hillside position above the coast provides excellent solar exposure for the majority of properties in this small community. The coastal location and unobstructed southern aspect deliver some of the best solar generation potential in the St Austell Bay area. Cornwall receives 1,298 kWh/m² of solar irradiance per year and a 4kW system here generates approximately 3,700–4,000 kWh annually. For the significant proportion of Duporth properties off the mains gas grid, combining solar panels with an oil-to-heat-pump switch creates exceptional energy cost savings and reduces reliance on fossil fuel deliveries. Most properties have standard permitted development rights for solar installation, though roof pitch and orientation should be assessed during survey. CCS Heating & Renewables installs solar panels with 0% VAT across the PL25 and PL26 areas.
