Commercial solar panel installers in Whitehaven
Whitehaven's economy is inseparable from the Sellafield nuclear licensed site 15 miles down the West Cumbria coast - the town hosts one of the densest concentrations of nuclear tier-2 supply-chain engineering, project-management and specialist-services businesses in the UK. Westlakes Science & Technology Park at Moor Row anchors the modern R&D and engineering-consultancy footprint, the Whitehaven harbour and Bransty industrial belt carry the mature light-manufacturing and marine-services stock, and the CA28 hinterland picks up substantial hospitality and West Cumbria coastal SME activity. Electricity North West's Whitehaven 33 kV was reinforced during the Sellafield decommissioning programme scale-up.

Does Sellafield tier-2 supplier scoring reward rooftop PV?
Yes - the NDA and Sellafield Ltd publish supplier decarbonisation frameworks that cascade Scope-3 evidence requirements to their West Cumbria tier-2 engineering, PM and services suppliers. Rooftop PV with a G99 acceptance letter is a directly-quotable Scope-1/2 reduction lever within the supplier scorecard used at Westlakes and Bransty.
Is Irish Sea coastal-atmosphere corrosion a real risk?
Yes - the West Cumbria coast is more corrosive than the average UK coast because of prevailing westerly Atlantic weather. We default to marine-grade anodised mounting, A4 (316) stainless fasteners and IP68 inverter enclosures for every CA28 site inside 5 km of the coastline, and upgrade roof flashings to marine cladding standard.
How does Electricity North West handle CA28 G99?
Sub-500 kWp with export limitation typically completes acceptance inside 10–14 weeks on the Bransty and Westlakes feeders. Whitehaven 33 kV was reinforced during the Sellafield decommissioning programme scale-up and mid-size array headroom is materially better than pre-2015.
What yield does a CA28 shed deliver?
Around 890–930 kWh per kWp per year on shallow east-west sheds and up to around 950 on a south-facing pitch. Cool Irish-Sea ambient panel-temperature lift and long summer daylight hours offset the peak-noon gap versus the south meaningfully.
How wide is Whitehaven coverage?
Bransty, Kells, Moor Row, Cleator Moor, Egremont, Frizington and St Bees are day-one visits. Workington, Cockermouth, Millom, Sellafield perimeter services and Maryport are on scheduled survey days from the CA28 base.
