Commercial solar panel installers in Barry
Barry is the principal commercial town of the Vale of Glamorgan south-west of Cardiff - the Barry Docks estate (Associated British Ports) carries the mature heavy-industrial and chemicals footprint (Dow Corning's Barry silicones plant is a long-standing anchor), the Waterfront regeneration delivers newer mixed-use commercial stock, and the CF62/CF63 hinterland carries substantial Cardiff-Airport-adjacent aviation and logistics activity. National Grid Electricity Distribution's Barry 33 kV holds meaningful post-industrial headroom.

- Typical system size
- 250 kWp - 1 MWp+
- Typical payback
- 3.5 - 4.5 years
- On-site self-consumption
- 70 - 85%
Indicative figures for well-matched UK sites - your feasibility review models your actual roof, demand and tariff.

Does Welsh SMART Cymru grant funding stack with UK-wide AIA on Barry PV?
Yes - SMART Cymru is a state-aid-notified Welsh Government grant (typically 30–50% of qualifying decarbonisation spend for eligible SMEs) and stacks with the UK-wide 100% Annual Investment Allowance on the after-grant net capital cost. Early advice is essential to avoid double-counting under the state-aid ceiling.
Are Barry Docks COMAH-tier sites PV-viable?
Yes with proper controls - Dow Silicones Barry is an upper-tier COMAH site and any PV within its consultation-distance triggers a HSE upper-tier COMAH consultation as part of planning. We handle this in-house with a dedicated COMAH-compliance workstream alongside standard G99 and structural design. Non-COMAH port-estate plots proceed under standard permitted development.
How does NGED handle CF62/CF63 G99?
Barry retains meaningful post-industrial headroom on the 33 kV feeders serving the Docks and Cadoxton - sub-500 kWp G99 with export limitation typically clears in 8–12 weeks, and 1 MWp+ remains deliverable subject to network study, particularly on ABP-estate plots with existing private-wire infrastructure.
Is CF62 / CF63 irradiance strong for commercial PV?
Yes - CF62 / CF63 delivers around 1,000–1,040 kWh per kWp per year, in the strong South Wales irradiance band. Waterfront-tier mixed-use and Docks-tier heavy-industrial load profiles both drive PV self-consumption into the high 70s to mid-80s of percent on well-sized rooftop arrays.
How wide is Barry coverage?
Cadoxton, Barry Island, Sully, Dinas Powys, Rhoose, Penarth and Cardiff Airport are day-one visits; Cardiff, Bridgend, Cowbridge, Llantwit Major and Cardiff Bay are on planned survey days from the Vale base.
