The Sonnedix Gonerby solar panel farm lies across the Marston and Gonerby parish boundaries. Approximately 40% is located within Marston and is accessible from Cliff Lane. That part beyond Foston Beck is in Gonerby. Owned and operated by Sonnedix UK Services Ltd., it came on line on 17 June 2026 with a capacity of almost 60 MW. Expected output in a typical year is around 58,000 MWh (58 GWh). This is enough to power over 15,000 homes and avoid around 20,000 tonnes of CO₂e emissions.
(Note: The part of the farm in the top right of the image is within Marston. The diagonal line to the bottom left is the A1.)
