Solar Panel Installation in Swansea — Tailored to Your Home
Swansea offers strong conditions for solar generation. A typical installation here can produce around 10% more electricity than an equivalent system in North Wales — and with energy costs remaining high, that translates into meaningful savings from day one.
A well-designed system can significantly reduce your reliance on the grid, lowering electricity bills, improving household efficiency and strengthening long-term financial returns.
Across the city, property type plays a key role in system size and savings potential.
In more densely populated areas such as Uplands, Brynmill, Sketty and Mount Pleasant, smaller roof spaces typically accommodate 8 to 12 panels. When paired with a battery and export tariff, this can deliver annual savings of approximately £700 to £1,000.
In more suburban areas such as Mumbles, Newton, Killay and Dunvant, larger properties can typically accommodate 12 to 20 panels — increasing potential savings to around £1,050 to £1,700 per year under the same conditions.
Most installers don't account for this. The same package gets sold to a terrace in Brynmill and a detached home in Mumbles — regardless of roof layout, orientation or how the household actually uses energy.
At Ulex Energy, we take a different approach — designing systems specifically around your home, your roof and your long-term goals. From Victorian terraces to large detached homes, Cardiff's housing stock is varied, and achieving the best results depends on getting the design right from the outset.
