Commercial Solar Across Southampton, Estate by Estate

Southampton is one of the strongest commercial solar locations in the UK because the South Coast receives close to 1,000 kWh of generation per kWp installed — meaningfully more than the Midlands or the North. A 100kWp rooftop array on a city warehouse or factory will generate around 100,000 kWh a year, costs roughly £75,000-£105,000, and typically pays back in 4-6 years, or closer to 3-4.5 years once Annual Investment Allowance relief (a roughly 25% cash benefit at the 25% corporation-tax rate) is applied. Because Southampton falls within SSEN's (Scottish and Southern Electricity Networks) distribution area — not NGED or UKPN — we lodge every grid application directly with SSEN: a G98 notification for arrays under 50kWp, and a full G99 application (around 65 working days) for the larger 200-500kWp systems common on the city's logistics sheds.

We install across every commercial pocket of the city. Around Cold Harbour, Aldermoor and Lordswood in the SO16 north of the city, we work with light-industrial units and trade premises. The big draw, though, is the distribution belt: Nursling Industrial Estate on Mauretania Road and the Test Lane / Nursling South logistics parks beside the M271 and M27 — home to John Lewis's distribution centre and large Peel Logistics sheds — offer exactly the kind of unshaded, single-span roofs that suit 250kWp+ arrays. We also cover the ABP Western Docks port estate, Hazel Road in Woolston, and the wider Solent corridor out to Chickenhall Lane in Eastleigh, Segensworth at Fareham and the Marchwood estate across Southampton Water.

Cold Harbour / Aldermoor / Lordswood (SO16): trade counters and light-industrial units — 30-100kWp, £22k-£105k, payback 4-6 years.
Nursling & Test Lane logistics sheds: large unbroken roofs ideal for 200-500kWp G99 arrays generating 200,000-500,000 kWh a year.
Western Docks & port-side operators: high daytime demand from refrigeration and handling equipment, maximising self-consumption.

Frequently Asked Questions

Do you fit commercial solar panels in Cold Harbour, Southampton?

Yes. We install commercial solar across Cold Harbour, Aldermoor, Lordswood and the SO16 area of north Southampton, as well as the city's main distribution estates. A typical 30-100kWp rooftop array on a Cold Harbour trade or light-industrial unit costs around £22,000-£105,000 and pays back in roughly four to six years. All work is MCS certified with a free site survey.

Who provides commercial PV systems on the South Coast?

We design and install commercial PV systems right across the South Coast, from Southampton and the Solent out to Eastleigh, Fareham and Portsmouth. The region's high irradiance — about 1,000 kWh per kWp — makes it one of the best-yielding solar locations in the UK, so South Coast businesses see faster payback than sites further north. We manage the full SSEN grid connection on every project.

How much does commercial solar cost in Southampton?

Commercial solar in Southampton runs at roughly £0.75-£1.05 per watt installed, so a 100kWp system is around £75,000-£105,000. With South Coast generation near 1,000 kWh per kWp that array produces close to 100,000 kWh a year, and payback is typically 4-6 years — or 3-4.5 years after Annual Investment Allowance relief (a roughly 25% cash benefit at the 25% corporation-tax rate).

Which DNO covers Southampton for a G99 solar connection?

Southampton and the rest of Hampshire are served by SSEN (Scottish and Southern Electricity Networks), not NGED or UKPN. We submit a G98 notification for systems under 50kWp and a full G99 application — around 65 working days — for the larger arrays common on Nursling and Test Lane logistics roofs, handling all SSEN paperwork on your behalf.
