Solar in Cardiff
Cardiff is a genuinely good solar city. South Wales gets some of the better daylight totals in the UK, and the wide streets of Roath, Cathays and Pontcanna, the interwar semis of Whitchurch and Llanishen, and the newer homes out at Cardiff Bay and Pentwyn all suit rooftop solar — provided the array is designed around each roof's pitch and orientation rather than dropped on as a fixed package.
A lot of Cardiff's terraced streets run in long rows where roof orientation and shading from the row itself matter a great deal. That's the sort of thing a proper survey catches and a rushed doorstep quote misses — we look at exactly which roof planes give you the best return before we recommend a size.
Pairing solar with a battery makes particular sense here: you store the daytime surplus and draw it down through the evening, and the Smart Export Guarantee pays you for anything left over that you send back to the grid. Your network operator across most of Cardiff is National Grid Electricity Distribution, and we handle the connection paperwork as part of the install.

From a real Cardiff customer
Excellent service from start to finish!
The entire process was smooth, well-coordinated, and clearly communicated throughout. The Geko engineer who designed our system was incredibly helpful and responsive. Really pleased with the outcome.
The Geko difference
Not your typical solar company
Most of the solar industry runs on doorstep reps and subcontractors. We built Geko to be the opposite.
FAQ
Solar in Cardiff — common questions.
Which parts of Cardiff and South Wales do you cover?
The full CF postcode area and surrounding towns — including Penarth, Barry, Caerphilly, Cowbridge, Radyr, Dinas Powys and across towards Newport and Pontypridd.
Is Cardiff a good place for solar?
Yes — South Wales sees some of the stronger daylight totals in the UK. A well-sized system covers much of your daytime use, a battery stores the surplus for the evening, and the Smart Export Guarantee pays you for what you export.
Have you installed in Cardiff?
Yes — there's a real Cardiff customer review on this page. Our own engineers install across the city and South Wales directly.
I'm in a Cardiff terrace — will orientation be a problem?
Terraced streets are common across Cardiff and we install on them regularly. Orientation and shading from the row do matter, which is why we survey and design around your specific roof planes rather than quoting blind.
Do you handle the grid connection paperwork?
Yes. We manage the DNO notification with your network operator and the commissioning as part of the install — you don't need to chase any forms.
