South East England
Solar Panels in Hampshire
We connect homeowners across Hampshire with MCS-certified solar installers. A large, mostly flat coastal county stretching from Southampton and Portsmouth to the New Forest, with consistently strong solar yield across both its cities and rural south.
Solar generation in Hampshire
According to PVGIS irradiance data for South East England, a typical 4 kWp south-facing system in Hampshire generates around 4,080 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £1,000 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 Hampshire. At current energy prices, most homeowners break even within 8–10 years.
Local grid: SSEN Distribution (Southern)
Every solar install in Hampshire connects to the grid through SSEN Distribution (Southern), 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.
