Solar panel installers in Exeter

A typical 4kWp solar panel system in Exeter costs between £4,950 and £6,950 fully installed, with 0% VAT until March 2027. Based on local sunshine hours, a system that size generates around 4,120 kWh a year and saves roughly £850 annually — a payback of about 6.8 years.

Exeter is in the South West, where the highest solar irradiance in the UK, so systems here generate more per kW installed. Local electricity at around 27.2p per kWh means every unit your panels offset is worth that much off your bill, and surplus is paid for through the Smart Export Guarantee (typically 12–15p/kWh).

Homes in the area are typically a mix of period homes and newer estates. Roof orientation and shading matter more than postcode: a south-facing, unshaded roof will out-perform, while east–west roofs still pay back well because they spread generation across the day, when you're more likely to use it.

Adding a battery lets you store daytime generation for evening use, pushing self-consumption from around 45% to 65%+ — usually worth it where electricity prices are higher, as they are locally. Your quote will model both options against your actual bill.
