South East England
Solar Panels in West Sussex
We connect homeowners across West Sussex with MCS-certified solar installers. The South Downs National Park and a mild Channel-coast climate give West Sussex, from Chichester to Crawley, some of the strongest solar yield in southern England.
Solar generation in West Sussex
According to PVGIS irradiance data for South East England, a typical 4 kWp south-facing system in West Sussex generates 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 West Sussex. At current energy prices, most homeowners break even within 8–10 years.
Local grid: UK Power Networks (South East)
Every solar install in West Sussex connects to the grid through UK Power Networks (South East), who require a G98 notification for systems up to 3.68 kW or G99 approval (up to 45 working days) for anything larger. Your MCS-certified installer takes care of whichever applies, included in the price.
