Solar Panels in Powys
We connect homeowners across Powys with MCS-certified solar installers. Wales's largest and most sparsely populated county is almost entirely rural upland, with farms and detached homes that often have far more usable roof and land area than urban Welsh housing.
Solar generation in Powys
Using PVGIS irradiance data for Wales, a 4 kWp south-facing array in Powys produces roughly 3,600 kWh per year. At the April 2026 Ofgem price cap of 24.50p/kWh, that covers £882 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 Powys. At current energy prices, most homeowners break even within 9–11 years.
Local grid: SP Energy Networks (SP Manweb)
Anywhere in Powys, the grid connection for a new system goes via SP Energy Networks (SP Manweb). Smaller systems (up to 3.68 kW) just need a G98 notification, while bigger ones need G99 approval — allow up to 45 working days for that. Either way, it's your MCS-certified installer's job, not an added fee.
