Commercial Solar Panels & Battery Storage in Stevenage

There is no single figure — cost scales with roof size and load. A typical mid-size Pin Green trade or light-industrial unit might install a 30-50kW system, while larger Gunnels Wood warehouse and manufacturing roofs often support 100-250kW or more. With Stevenage commercial electricity at around 22-27p/kWh and 100% Annual Investment Allowance relief on the capital in year one, most Stevenage installs reach payback in 3-6 years. We provide a fixed written quote after a free roof survey.

Most rooftop commercial solar in Stevenage proceeds under permitted development rights and does not need a full planning application. However, the Gunnels Wood and Pin Green employment areas are covered by Article 4 Directions, and conservation-area or listed-building status can change what is allowed, so we always run a planning check with Stevenage Borough Council as part of the survey before any work starts.

The Distribution Network Operator across Stevenage and the whole East-of-England region is UK Power Networks (UKPN). Smaller systems are notified under G98 and larger commercial arrays (above 3.68kW per phase) are applied for under G99. We handle the full UKPN application and any required network study on your behalf as part of the installation.

For a typical Stevenage commercial roof, the physical installation takes from a few days to around two weeks depending on system size and any electrical upgrade work. The longer lead time is usually the UKPN G99 grid-connection approval for larger systems, which we manage in parallel so your Gunnels Wood or Pin Green site stays operational throughout.

The main financial benefit for Stevenage businesses is the 100% Annual Investment Allowance, which lets you deduct the full cost of a qualifying solar and battery system against taxable profits in the year of purchase, up to the £1m AIA cap. Combined with 3-6 year payback and the borough's net-zero-by-2030 agenda, this makes on-site generation strongly cost-effective; we outline the exact tax treatment in every quote.

Often yes. Many Stevenage sites — particularly Gunnels Wood manufacturers and Pin Green units running refrigeration, plant or EV charging — have demand that peaks at expensive times or continues after dark. A battery lets you store daytime solar generation, shift it to peak periods, and add resilience against grid-price volatility, improving overall returns beyond solar alone. We size storage to your actual half-hourly consumption.

Yes. We work across the full range of Stevenage commercial roofs, from single trade-counter units to large warehouse, distribution and manufacturing buildings of the type found along Gunnels Wood Road and Six Hills Way. We handle structural roof assessment, UKPN grid connection, and phased installation to keep operations running on active sites.

We cover the whole of Stevenage across the SG1 and SG2 postcode districts, including the Gunnels Wood and Pin Green employment areas, the town centre and out-of-town retail sites. Stevenage sits well within EC Eco Energy's 30-mile service radius from Sawbridgeworth, and we also serve neighbouring towns such as Welwyn Garden City, Hatfield, Hertford and Buntingford.

Stevenage receives roughly 1,250-1,320 kWh/m² of solar irradiance a year, typical for the East of England. A well-oriented, unshaded commercial roof will produce most of its output during working hours, when demand and grid prices are highest — which is exactly why daytime-load Stevenage businesses see the fastest payback. We model your specific roof orientation and pitch to give a firm annual generation estimate before you commit.
