Solar Services in Cardiff
Cardiff is one of our listed service areas. We offer solar services for homes and businesses across the city, from Canton and Pontcanna to Whitchurch, Rhiwbina, Llandaff, Roath, Penylan, Cyncoed and Pontprennau.
We will confirm visit timings when you enquire, based on our schedule and the work you need.
Services available to Cardiff households include new solar installations, Fox battery storage, inverter replacements and fault finding on existing systems. Sam Hayes brings 12 years in solar and 25 years in construction to every job.
Homes in Cardiff
Much of Cardiff's housing is late Victorian and Edwardian terraces, particularly in Roath, Cathays, Canton, Grangetown and Splott. These homes often have slate roofs, narrow frontages and rear outriggers, so making the best use of limited roof space takes careful planning.
Further out, suburbs such as Llanishen, Rhiwbina, Whitchurch and Cyncoed have larger interwar and post-war semis and detached homes with bigger roofs, while newer developments in places like Pontprennau and the Bay often have modern tiled roofs well suited to solar.

Solar Challenges in Cardiff
Limited roof space on terraces
Narrow terraced roofs and outriggers limit panel numbers, so layout matters more.
Shading in dense streets
Chimneys, neighbouring buildings and mature street trees can shade parts of a roof.
Older electrics
Some older homes have consumer units that need checking before solar, batteries or EV chargers are added.
City pigeons
Pigeons are common in urban Cardiff and readily nest under panels.
Solar in a busy city
City homes collect traffic film and grime faster than rural ones, which can reduce output over time. Combined with pigeons, cleaning and bird proofing may be worth considering where there is soiling or nesting activity.
Cardiff businesses
We also install commercial solar PV for business premises in and around Cardiff, where daytime demand matches solar generation well.
Roath, Cathays and Canton terraces
In Cardiff's terraced streets, the main roof often faces the road and the rear outrigger roof faces the garden. Depending on orientation, one or both can carry panels. We look at both before recommending a layout, taking account of available space, shading and roof orientation.
Suburban Cardiff
In suburbs such as Llanishen, Rhiwbina, Whitchurch and Cyncoed, larger semi-detached and detached homes often have more roof space and driveways, making them good candidates for a combined solar, battery and EV charger setup planned as one system.
Cardiff conservation areas
Parts of Cardiff, including areas of Llandaff, Cathedral Road and Penylan, are conservation areas where visible roof installations may need planning permission. Check with the council before going ahead.
Planning Solar for Your Cardiff Home
The best solar systems in Cardiff start with an honest look at the property. We consider which way your roof faces, how steep it is, what it is covered with and whether anything shades it during the day. We also look at your consumer unit and how your household uses electricity, because system suitability depends on your property and how you use electricity.
If you are thinking about a battery or an EV charger, tell us at the start. Planning these together can help identify compatible equipment and cabling requirements. If you already have panels in Cardiff that are not performing, we can investigate potential causes, including inverter faults, wiring issues, dirt or nesting birds.
Every quote is individual. You will get a clear explanation of what we recommend and why, and nothing goes ahead until you are happy. Payment is by bank transfer or credit/debit card.
Already Have Solar in Cardiff?
If you already have panels, you may need help with missing paperwork, falling generation, inverter errors or battery performance. We offer fault finding and maintenance for existing installations. Tell us your equipment details so we can confirm the support available and quote for suitable work. Common fixes include replacing a failed inverter with a Fox unit, adding a battery, cleaning panels and fitting bird mesh.
