GL Solar is Cardiff's leading residential solar panel installer, with over 500 completed installations across the city and surrounding South Wales region. Whether you live in a Victorian terrace in Roath, a 1930s semi in Whitchurch, a period property in Pontcanna, or a modern new build in Pontprennau — we have the expertise to design and install a solar system that maximises your energy generation and savings.
A typical 4kW solar panel system in Cardiff generates around 3,400–3,800 kWh per year — enough to cover a significant portion of an average household's electricity needs. With energy prices remaining high, Cardiff homeowners are seeing payback periods of just 6–8 years, followed by decades of free electricity. Add battery storage and you can push self-consumption above 70%, dramatically increasing your savings year-round.
As a fully MCS certified installer, all our residential solar installations qualify for the Smart Export Guarantee (SEG), meaning you get paid for every unit of surplus electricity you export back to the grid. We handle all the paperwork, DNO applications and grid connection notifications — you just enjoy the savings. Our Cardiff team is also NAPIT registered, ensuring all electrical work meets the highest safety standards.
Cardiff's climate is better for solar than most people think. With around 1,600 hours of sunshine per year and excellent south-facing roof potential across the city's suburbs, Cardiff homeowners consistently achieve strong solar generation figures. Even on overcast days, modern solar panels generate 10–25% of their peak output — meaning your system works year-round, not just in summer.

Real reviews from homeowners and businesses across Cardiff and South Wales.
“GL Solar installed a 5kW system with GivEnergy battery on our semi in Whitchurch. The whole process was seamless — from the free survey to switch-on took just 3 weeks. We're already seeing our bills drop significantly and the monitoring app is brilliant. Highly recommend to anyone in Cardiff.”
“Brilliant service from start to finish. The team were professional, tidy and explained everything clearly. Our new build now has a 4kW system and we're generating more than we expected even in winter. Great investment — wish we'd done it sooner.”
“We had quotes from three companies and GL Solar were the most knowledgeable and competitively priced. The installation was completed in a day and the system has been faultless. Our electricity bills have halved and we're earning from the SEG every month.”
“Had solar panels fitted on our Victorian terrace in Canton. GL Solar were brilliant at working around the slate roof and the installation looks really neat. Already saving money and the team were so helpful explaining how to get the most from the system.”
“Excellent company. Very professional from start to finish. The survey was thorough, the quote was detailed and the installation was completed on time. The system is performing above the projected figures. Would definitely recommend GL Solar to anyone in Cardiff.”
