Solar Panels in East Sussex
We connect homeowners across East Sussex with MCS-certified solar installers. The South Downs and English Channel coastline give East Sussex some of the clearest, most exposed southerly roof aspects in the country, from Brighton to Hastings.
Solar generation in East Sussex
Drawing on PVGIS irradiance data for South East England, a south-facing 4 kWp system in East Sussex is expected to generate around 4,060 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £995 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 East Sussex. At current energy prices, most homeowners break even within 8–10 years.
Local grid: UK Power Networks (South East)
Across East Sussex, solar installations connect to the grid via UK Power Networks (South East). A G98 notification covers anything up to 3.68 kW; larger systems need G99 approval instead, which can take up to 45 working days. Both are handled by your MCS-certified installer as standard, at no extra cost.
