Commercial PV in Swansea — Why Now?
Swansea and South Wales has emerged as one of the UK's most active commercial solar markets, driven by a combination of high industrial energy costs, Welsh Government net zero policy, and an outstanding manufacturing base ripe for solar investment.
Welsh Government Net Zero Policy
Wales has a statutory target of net zero by 2050, with the Welsh Government actively funding decarbonisation through Business Wales grants and the Development Bank of Wales green lending programme. Commercial PV installers in Swansea are seeing unprecedented demand as businesses respond to these policy signals.
Swansea Bay's Industrial Base
The Swansea Bay region includes Neath Port Talbot (steel and metal), Llanelli (manufacturing), the Swansea Enterprise Zone, and Felindre Business Park. These energy-intensive operations have large metal roofs, three-phase supplies and predictable consumption patterns — ideal for commercial PV installation.
Good Solar Irradiance
Swansea receives 970–1,010 kWh/kWp of annual solar irradiance — very close to the UK average. A 100kW commercial PV system in Swansea generates approximately 90,000–97,000 kWh annually, delivering £22,000–£28,000 in energy savings at typical South Wales commercial electricity rates of 25–30p/kWh.
DNO: Western Power Distribution / National Grid ET
Commercial PV systems up to 3.68kW per phase can be connected under G98 notification (within 28 days of commissioning). Larger systems require a formal G99 application to National Grid Electricity Distribution (formerly WPD in Wales) — typically 6–10 weeks. The installer normally manages the DNO process; ask who will do it and whether it is included in the quote.

Bath and the wider Somerset region has a growing commercial solar market, led by manufacturing and food processing businesses targeting net zero and responding to BANES Council's climate action framework.
Commercial PV in Bath — What You Need to Know
Planning Considerations in Bath
Bath is a UNESCO World Heritage Site and has significant Conservation Area and Listed Building constraints. Most commercial and industrial buildings outside the city centre heritage zones qualify for permitted development for rooftop solar. Ask the installer to include a planning assessment in the site survey — if full planning is needed, the application goes to Bath & North East Somerset Council, so ask who will submit it and whether that cost is in the quote.
Bath's Industrial and Commercial Areas
Bath's main commercial solar opportunities are in the Westmoreland Street area, the Weston estate, Locksbrook Road, and the wider Bath Enterprise Zone. Industrial occupiers in the B1/B2/B8 zones typically have straightforward rooftops ideal for commercial PV installation.
Solar Irradiance in Bath
Bath (BA1–BA2) receives approximately 1,020–1,050 kWh/kWp annually — slightly above the UK average due to the South West's latitude and lower cloud cover. A 100kW system in Bath generates approximately 92,000–98,000 kWh per year, delivering £23,000–£29,000 in annual savings.
