Commercial solar installers in Aberystwyth

Key facts

Where businesses are in Aberystwyth

• Glanyrafon Industrial Estate, Llanbadarn Fawr: Built in the 1970s on the south bank of the River Rheidol about two miles south east of the town centre, covering roughly 700 by 500 metres. Wales's national heritage record lists units including the Post Office depot, Rachel's Organic, a plumbing centre and Screwfix.
• AberInnovation (Aberystwyth Innovation and Enterprise Campus), Gogerddan: Innovation campus on Aberystwyth University's Gogerddan site with pilot scale facilities for food and drink, the circular economy and agri-tech, including a Biorefining Centre, Future Food Centre, Seed Biobank and offices and labs to hire.

Large employers and sectors with sites here include:

• Higher education (Aberystwyth University): Aberystwyth University was founded in 1872 as the first university college in Wales. A report for Universities Wales in October 2021 found that universities in Ceredigion contributed £135m a year to the county's economy and supported 3,303 jobs there.
• Dairy (Rachel's Organic): In November 2023 Rachel's, a subsidiary of Lactalis, was making its organic yoghurts at its Aberystwyth site, with organic milk delivered daily and spare capacity it hoped to fill; the brand produced about 6,000 tonnes of yoghurt a year.

Large, simple roofs on distribution sheds and modern industrial units are usually the quickest and cheapest to fit. Older mill, factory and workshop buildings can work well too, but often need a structural survey first, and roofs from before 2000 may contain asbestos cement: see asbestos roofs.

Grid connection

Aberystwyth is served by SP Energy Networks (SP Manweb, Merseyside and North Wales licence area). Almost every commercial system needs G99 approval from the network operator before it is switched on, and the question is usually how much the local network can take back. Where export is limited, a G100 export limitation scheme can let a larger array connect. See G99 and DNO applications.

Planning in Aberystwyth

Planning in Aberystwyth is decided by Ceredigion council under the Welsh rules. Many non-domestic roofs are covered by Welsh permitted development, with conditions, but not within 3 km of an airport or aerodrome or on listed buildings.

Points that come up locally:

• The Aberystwyth Conservation Area, designated in 1969 and extended in 1980, 1981 and 1984, holds 249 listed buildings, according to the council's June 2025 appraisal, so check a building's status before planning roof panels in the centre.
• In Wales, roof panels on a non-domestic building are usually permitted development if they stand no more than 200mm proud of the roof, but in a conservation area panels on a principal or side elevation wall visible from a highway need planning consent, and a listed building needs planning permission and listed building consent.

Our guides on listed buildings and conservation areas explain what these mean for a solar project.

What a business roof in Aberystwyth could generate

Modelled with PVGIS for the town centre, a south-facing roof at 30 degrees produces about 948 kWh per kWp a year.

Illustrative, not a quote: the same sums as our commercial solar calculator. A company paying corporation tax can usually shorten the payback with capital allowances.

Funding and support

• Development Bank of Wales Green Business Loan Scheme: Discounted fixed interest rate loans for energy efficiency measures and low carbon projects, with renewables including solar PV listed as eligible projects. Limited companies, sole traders and partnerships must be based in Wales, have traded for at least two years and have at least one set of filed annual accounts. A grant of up to 50% of the cost of a detailed energy audit, to a maximum of £10,000 (£20,000 total costs), is also offered. Check the scheme's own page for eligibility and closing dates.

National reliefs apply too: see grants and reliefs in Wales.
