Cardiff is packed with Victorian terraces — from the leafy streets of Pontcanna and Canton to the dense rows of Roath, Cathays and Grangetown. If you live in one, you might wonder whether solar panels are even possible. The answer is a resounding yes, and we install on Victorian terraces every single week across the city.
The Victorian Terrace Solar Challenge — and How We Solve It
Victorian terraces were built in long rows running roughly north-south, which means one roof slope faces east and the other faces west. This is different from the ideal south-facing setup — but it doesn't mean solar won't work. Here's what actually matters:
Many Cardiff terraces have rear roofs that face south or south-west — perfect for solar. We check this during your free survey.
Splitting panels across both slopes can actually smooth out generation across the day, reducing your reliance on the grid morning and evening.
A typical Cardiff terrace rear roof fits 6–10 panels (2.4–4kW). That's enough to cover 40–70% of your electricity needs.
A home battery is especially valuable for terraces — it stores daytime solar for evening use, maximising self-consumption when roof space is limited.

Planning Rules for Victorian Terraces in Cardiff
Most Cardiff Victorian terraces don't need planning permission for solar panels — they fall under permitted development rights. However, there are two important exceptions:
Cardiff Victorian Terrace Areas We Cover
We install solar panels on Victorian terraces across all of Cardiff's terrace-heavy neighbourhoods:
Customer Story: Canton Victorian Terrace
"I was worried my Victorian terrace wouldn't be suitable — the front faces north and the street is quite narrow. GL Solar came out, assessed the rear roof (which faces south-west) and said it was perfect. They installed 8 panels and a GivEnergy battery. My bills have dropped by over £800 a year. Wish I'd done it sooner."
Frequently Asked Questions
Can I get solar panels on a Victorian terrace in Cardiff?
Absolutely. Victorian terraces are one of the most common property types we install on across Cardiff. The key is roof orientation — if your rear roof faces south, south-east or south-west, you're in a great position. Even east or west-facing roofs can generate meaningful savings.
Do I need planning permission for solar on a Victorian terrace?
In most cases, no. Solar panels on terraced houses fall under permitted development rights, meaning no planning permission is needed. The exception is if your home is in a conservation area (parts of Pontcanna, Canton, Roath) or is a listed building — in those cases, panels must not be visible from the street.
How many panels can fit on a Victorian terrace roof?
A typical Cardiff Victorian terrace rear roof can accommodate 6–10 panels (2.4–4kW system). This is enough to cover 40–70% of an average household's electricity needs and generate 2,000–3,500 kWh per year.
What about the front roof — can panels go there?
Technically yes, but we generally advise against it for Victorian terraces in conservation areas. For non-conservation streets, front-facing panels are possible but less efficient if north-facing. We always recommend a free survey to assess both roof aspects.
Will solar panels damage my Victorian terrace roof?
No — when installed correctly by MCS-certified engineers, solar panels actually protect the roof tiles beneath them. We use non-penetrating mounting systems where possible and always check the structural integrity of the roof before installation.
How much can a Victorian terrace in Cardiff save with solar?
Based on our Cardiff installations, a typical Victorian terrace with a 3.5kW system saves £600–£900 per year on electricity bills. Add a battery and that rises to £900–£1,200 per year. Payback period is typically 6–9 years.
What areas of Cardiff have the most Victorian terraces?
Roath, Canton, Pontcanna, Cathays, Grangetown, Splott, Adamsdown and Riverside are all densely packed with Victorian and Edwardian terraces. We've installed on hundreds of homes across all these areas.
