Serving St Davids
St Davids -- Tyddewi in Welsh -- is the smallest city in Britain by population, carrying approximately 1,800 residents, yet holds city status by virtue of its cathedral and the presence of the patron saint of Wales. The city sits on the St Davids Peninsula at the westernmost point of Wales, inside the Pembrokeshire Coast National Park, and benefits from the highest solar irradiation of any location in FLD's entire coverage area.
The PVGIS yield for SA62 sits at 995 kWh/kWp -- fractionally below 1,000, and among the highest in England and Wales. The Peninsula faces directly south-west across St Brides Bay toward the Atlantic, with almost no horizon obstruction beyond the coastal cliffs. Solar panels here generate more energy per kilowatt of installed capacity than anywhere on the South Wales mainland.
The local economy is dominated by religious and cultural tourism anchored by St Davids Cathedral, Britain's westernmost cathedral and a Grade I listed building attracting over 300,000 visitors per year. RSPB Ramsey Island boat trips, the Pembrokeshire Coastal Path which passes through the city, and a cluster of outdoor activity operators make up the balance. Commercial floorspace is limited to the Cross Square area, Oriel y Parc (the national park gallery and visitor centre), and small-scale hospitality and retail.
Residential stock is almost entirely granite and local-stone cottages with slate roofs -- properties where in-roof integrated solar is typically specified rather than on-roof rail-mounted systems, both to satisfy Pembrokeshire Coast National Park design guidance and to protect the historic stone fabric from unnecessary penetrations. In-roof systems cost approximately 30 to 50% more than equivalent on-roof capacity but are the standard FLD specification for this postcode.
The planning position here requires pre-application consultation with the National Park Authority for any front-elevation proposals or listed-building adjacencies. The PNPA planning officer is generally supportive of well-designed rear-roof solar for rural and tourism operations; opposition is directed at ground-mounted arrays in the open coastal landscape.
At 995 kWh/kWp, a 50 kWp hospitality rooftop in St Davids generates 49,750 kWh per year -- the maximum output we model for any South Wales installation of this size. Summer hospitality self-consumption peaks above 85% through June to August. First-year benefit: approximately £13,800 on £48,000 installed cost including in-roof integration premium.
FLD reaches St Davids via the A40 and B4583 in approximately 120 minutes from Swansea. Coverage here is planned as a dedicated north Pembrokeshire day combining with Fishguard, Haverfordwest and Pembroke Dock.
100 kWp reference system at 995 kWh/kWp
Modelled at 27p/kWh blended import, 12p/kWh SEG export, 65% self-consumption for medium energy intensity site.
Housing stock in St Davids
Granite and local-stone cottages, former rectory detacheds, rural farmhouses
A typical 4 kWp domestic install here generates 3,980 kWh/yr. With 40% self-consumption at 30p/kWh and 60% SEG export at 12p/kWh, first-year saving is approximately £764.

Looking after solar and electrical systems in St Davids
Installing the system is the short part. Most of what we do in St Davids is what comes after it.
Existing arrays around St Davids lose output quietly — soiling on the glass, a string that has dropped out, an inverter throwing a fault code nobody reads — so solar PV maintenance and panel cleaning is usually the first thing worth booking on a system that is a few years old.
Where a St Davids system exports more than it uses, retrofitting battery storage is what turns that export back into self-consumption, which is worth roughly double what the export tariff pays.
EV charge points is the other upgrade that pairs with an existing array in St Davids — charging off your own generation rather than off the grid changes the arithmetic completely.
On commercial premises in St Davids, LED and emergency lighting upgrades normally pays back faster than anything else on the building, and it cuts the load the solar has to cover in the first place.
We are 120 minutes from St Davids in normal traffic, which is why we can put an engineer on a fault the same week rather than the same month.
