Commercial Solar Installations Across Cardiff & South Wales

Commercial solar is one of the most effective ways for Cardiff businesses to reduce operating costs, meet sustainability targets and future-proof against rising energy prices. GL Solar has completed commercial installations across Cardiff and South Wales — from small retail units and offices to large warehouses and industrial facilities — and we bring that experience to every project we take on.

A well-designed commercial solar system can reduce your electricity bills by 50–70%, with most Cardiff businesses seeing full payback within 4–7 years. After that, you're generating free electricity for the remaining 20+ years of the system's life. With 0% VAT on commercial solar installations, the upfront cost is lower than many businesses expect — and enhanced capital allowances mean you can offset the full cost against corporation tax in year one.

We provide a complete commercial solar service — from initial feasibility survey and energy audit through to system design, planning applications, installation, commissioning and ongoing maintenance. Our team has experience with all commercial roof types, including flat roofs, pitched roofs, standing seam metal roofs and ground-mounted systems for larger sites across Cardiff and the Vale of Glamorgan.

Cardiff's commercial sector is increasingly under pressure to demonstrate green credentials — from planning requirements and BREEAM ratings to supply chain sustainability demands. A commercial solar installation from GL Solar delivers measurable carbon savings, improves your EPC rating and provides a compelling story for customers, investors and staff. We provide full documentation for ESG reporting and carbon reduction targets.

Our commercial team works with businesses of every size across South Wales. Whether you run a single shop in Cardiff city centre, a manufacturing plant in Newport, a hotel in Barry or a multi-site retail operation across the region, we'll design a solar system that matches your energy profile, roof constraints and budget. We've installed solar for schools, care homes, gyms, pubs, restaurants, churches, warehouses, offices and industrial sites — each with unique requirements that we tailor our approach to.
