Commercial solar in Swansea
Delivered in Swansea at Crymlyn Burrows — and engineered the same way everywhere: sized on your load profile, not your roof area.
Indicative system size, savings and payback in under a minute. No sign-up.
Delivered in Swansea
Delivered in Swansea at Crymlyn Burrows, and across South Wales — including a 5 MWp solar farm for Rhondda Cynon Taf Council, the nearest large-scale scheme to the city.
Delivered without disruption. Operating. Measurably saving.

The Swansea grid reality
South Wales sits in National Grid Electricity Distribution's licence area — the network operator formerly known as Western Power Distribution. Every commercial connection, capacity enquiry and G99 application here goes through NGED, and the position varies street by street rather than town by town.
Swansea's commercial base spans a wide range of connection positions — from the industrial supplies around Swansea Vale, Fforestfach and the Enterprise Zone through to smaller commercial units where the incoming supply is the binding constraint long before the roof is.
The practical consequence is the same everywhere: available capacity, not roof area, sets the ceiling on what's worth designing. We establish that position first, because it's the finding that most often changes a scheme — and it's far cheaper to know at the start.
How we handle grid connections“This system is not only good for the planet, it's an investment in the future sustainability of our organisation. By reducing our energy costs, we can focus more of our resources on supporting the community.”
Most people come to us for solar. Then we look at the whole site.
Solar is usually the first question, and it's rarely the whole answer. Before we size an array we look at what the site actually does — how it draws power, what the incoming supply can take, and what's coming in the next few years. That's what decides whether solar is worth 200 kWp or 800 kWp, and whether it should arrive on its own.
What your half-hourly data really says
Consumption data shows when you actually draw power, not when you assume you do. A site that runs hard overnight gets a different answer from one that peaks at midday — and that changes array size, export exposure and whether storage earns its place.
Whether your supply can take it
Available capacity at the incoming supply decides what can be connected without a reinforcement bill. It's the single most common reason a solar scheme gets re-scoped late, and the cheapest thing in the world to check early.
Storage, where it pays
Battery storage is not automatic. It earns its place when it shifts load off expensive periods, firms up resilience on a site that can't take an outage, or keeps generation on site instead of exporting it cheaply.
EV, before it's urgent
Fleet and staff charging almost always arrives after the solar. Designing the capacity headroom in now costs very little; retrofitting it into a site that's already at its limit costs a great deal.
One party accountable
We design, install, connect and maintain. When generation, storage, charging and the grid connection all sit with one contractor, nobody gets to point at somebody else when a commissioning date slips.
Funded, if you'd rather not spend capital
Capital purchase, PPA, asset finance or Energy-as-a-Service. The right structure depends on your balance sheet and how long you hold the site — not on what we'd prefer to sell.

Welsh funding and policy context
Welsh Government policy under Net Zero Wales sets a firmer direction on non-domestic decarbonisation than the equivalent position in England, with Development Bank of Wales lending and Ynni Cymru funding both relevant depending on the ownership structure.
Non-domestic rates in Wales are set by Welsh Government, so rating treatment is a Welsh question rather than a UK-wide one. For organisations with a community or third-sector dimension — of which Swansea has many — the funding routes available are genuinely different from a straightforward commercial purchase.
Planning in Swansea
Swansea Council is the local planning authority. Rooftop solar on existing commercial buildings usually falls within permitted development, with the familiar exceptions for listed buildings and conservation areas — a live consideration in the maritime quarter and the older commercial core.
Coastal exposure is a real design factor here rather than a planning one: wind loading and corrosion both affect mounting specification on exposed sites, and both are cheaper to design for than to remediate.
A commercial site is not a big domestic install
| Typical installer | Nuvolt | |
|---|---|---|
| Grid connection | Treated as paperwork at the end of the job. | Checked at the start, because available capacity decides what's worth designing. |
| Sizing | Fill the roof, or fit the budget. | Sized to your half-hourly load profile, so generation is used on site rather than exported cheaply. |
| Operations | Scaffold goes up, you work around it. | Programmed around trading and production hours — the constraint we design to first. |
| Funding | One price, take it or leave it. | CapEx, PPA, asset finance and EaaS modelled side by side against your balance sheet. |
| Afterwards | Warranty paperwork and a phone number. | Monitoring against the yield model, with O&M and a team an hour away at most. |
Who we work with around Swansea
Manufacturing
Swansea Vale and the wider industrial base, where process load and unit rate drive the business case.
Education
A significant education estate with carbon commitments and constrained capital budgets.
Charity & community
Where Welsh community energy funding routes change what's affordable.
Hospitality & leisure
Coastal and city venues with sharply seasonal load profiles.
Areas we cover around Swansea
We work across South Wales from our base at St Mellons, Cardiff — Swansea, Neath and Port Talbot are all inside our normal delivery area. If you're not on this list, ask — it isn't exhaustive.
How a Swansea project runs
- 01
Site and data review
Half-hourly consumption, roof or land survey, incoming supply capacity and constraints — before anything is sized.
- 02
Engineered design
System size, layout, structural and electrical design, yield modelling and a grid application route that reflects the real connection position.
- 03
Commercial structure
Capital purchase, PPA, asset finance or EaaS, modelled side by side so the numbers are comparable rather than pitched.
- 04
Delivery around operations
Programmed to your trading and production hours. On live commercial sites, disruption is the cost that doesn't appear on the quote.
- 05
Connection and commissioning
G99 application, DNO liaison, witness testing and energisation handled end to end.
- 06
Monitoring and O&M
Performance monitored against the model, with maintenance that keeps the asset generating what it was funded to generate.
