Roof Solar Installations for Every Cardiff Home
Cardiff's housing stock is wonderfully varied — from Victorian terraces in Roath and Canton to modern new-builds in St Mellons and Pontprennau. GL Solar has the expertise to install solar panels on virtually any roof type, ensuring a secure, weatherproof and aesthetically pleasing result every time.
Our roof solar installations use purpose-designed mounting systems for each roof type — whether that's traditional interlocking tile hooks for concrete tiles, specialist slate hooks for Welsh slate, or ballasted systems for flat roofs. Every installation is carried out to the highest structural and weatherproofing standards.
We're fully insured and our installations comply with all relevant British Standards and MCS guidelines. Your roof will be left in the same condition as we found it — or better.

“We have an old Welsh slate roof in Canton and were worried about finding someone who could handle it properly. GL Solar were brilliant — they used specialist slate hooks and the installation looks fantastic. No leaks, no damage, and the panels are generating brilliantly.”
