Solar Panel Installation in Cardiff
GL Solar is Cardiff's leading solar panel installation company, providing expert renewable energy solutions to homes and businesses across the city. From the Victorian terraces of Roath and Cathays to the modern developments in Pontprennau and St Mellons, we have installed solar PV systems on every type of property Cardiff has to offer.
Our Cardiff-based team understands the unique challenges of installing solar in the city — from navigating conservation area restrictions in Llandaff and Pontcanna to maximising roof space on compact city centre apartments. We handle everything from initial site survey and DNO application to full installation and commissioning, ensuring a hassle-free experience for Cardiff homeowners.
With energy prices continuing to rise, more Cardiff residents are turning to solar to take control of their electricity bills. A typical 4kW solar system in Cardiff can generate around 3,500 kWh per year — enough to power an average home and significantly reduce reliance on the grid. Combined with a battery storage system, you can store excess energy for use in the evening, maximising your savings.
