Solar Panel Installation in Cardiff

GL Solar is Cardiff's leading solar panel installation company, fitting high-quality solar PV systems on homes and businesses across every corner of the city. From the Victorian terraces of Roath and Cathays to the modern developments in Pontprennau and St Mellons, we have installed panels on every property type Cardiff has to offer.

Our Cardiff-based installers understand the unique challenges of fitting solar in the city — from navigating conservation area restrictions in Llandaff and Pontcanna to maximising generation on compact city centre roofs. We handle the full process: free survey, custom design, DNO application, installation and commissioning.

A typical 4kW solar panel installation in Cardiff generates around 3,500 kWh per year, cutting energy bills by £700–£1,100 annually. With energy prices continuing to rise, more Cardiff residents are choosing solar to take control of their electricity costs. We use only tier-1 panels from JA Solar, Jinko, REC, LONGi and Canadian Solar.
