Commercial solar panel installers in Stevenage
Stevenage runs one of the UK's strongest aerospace, defence and life-sciences clusters - Airbus, MBDA, GSK and the Stevenage Bioscience Catalyst sit alongside the Gunnels Wood industrial estate and Pin Green's high-tech manufacturers. Hertfordshire's south-band irradiance (1,000+ kWh/kWp/yr) combined with continuous cleanroom, lab and test-rig loads gives some of the best commercial-solar economics in the UK.
