South West England
Solar Panels in Devon
We connect homeowners across Devon with MCS-certified solar installers. England's second-largest county spans Dartmoor's exposed uplands and a sheltered South Devon coastline, both benefiting from some of the country's highest annual sunshine hours.
Solar generation in Devon
Based on PVGIS irradiance data for South West England, a 4 kWp south-facing system in Devon generates around 4,240 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £1,039 of electricity you would otherwise buy from the grid.
On top of bill savings, surplus energy exported to the grid earns Smart Export Guarantee (SEG) payments — typically 4–6p/kWh with the main suppliers, or up to 15p/kWh with specialist tariffs like Octopus Outgoing.
A typical 4 kWp system with a 5 kWh battery costs £7,000–£11,000 installed across Devon. At current energy prices, most homeowners break even within 8–10 years.
Local grid: National Grid Electricity Distribution (South West)
Solar installations across Devon connect to the grid via National Grid Electricity Distribution (South West). Systems up to 3.68 kW require a G98 notification; larger systems need G99 approval, which can take 45 working days. Your MCS-certified installer handles both — it's included in the installation package, not an extra cost.
About Devon
Devon's spread from Dartmoor's exposed uplands to the sheltered South Devon coast still benefits fairly evenly from some of the country's highest annual sunshine hours. Dartmoor's granite tors and Plymouth's naval dockyard heritage sit either side of the cathedral city of Exeter.
