Solar Maintenance, EV Chargers & Repairs in Cardiff
From annual servicing and emergency repairs to EV charger installation and electrical upgrades — GL Solar keeps your system running perfectly across Cardiff and South Wales.
GL Solar provides a comprehensive range of additional solar services across Cardiff and South Wales — from annual maintenance and emergency repairs to EV charger installation and electrical upgrades. Whether you need a quick inverter replacement, a full system health check or a brand new EV charger installed, our local Cardiff team is ready to help with fast response times and expert workmanship.
Regular maintenance is essential to keep your solar system performing at its best. Cardiff's climate — with its rain, wind and occasional moss and lichen growth — means annual servicing is particularly important. Our maintenance packages include panel cleaning, electrical safety checks, inverter performance analysis and a full generation report, ensuring your system continues to deliver maximum savings year after year.
We're also one of Cardiff's leading EV charger installers, approved by OZEV (the Office for Zero Emission Vehicles). We install smart EV chargers that integrate with your solar system, allowing you to charge your electric vehicle from free solar energy. The MyEnergi Zappi is our most popular solar-compatible charger — it automatically diverts surplus solar to your car, so you're charging for free whenever the sun shines.
Our electrical upgrade service covers everything from consumer unit replacements and rewiring to DNO applications and grid connection upgrades. Many Cardiff homes — particularly those built before 2000 — need electrical upgrades before solar panels, battery storage or EV chargers can be safely installed. Our NAPIT registered electricians handle all of this as part of a seamless, single-contractor service.

What Cardiff Customers Say
Real reviews from homeowners and businesses across Cardiff and South Wales.
“Our inverter failed after 8 years and GL Solar had it diagnosed and replaced within 48 hours. They identified the fault quickly, sourced a compatible replacement and had us back generating the same day. Brilliant service — highly recommend for solar repairs in Cardiff.”
“Had a Zappi EV charger installed alongside my existing solar panels. The team were brilliant — they integrated it perfectly with my solar system so I can now charge my car from free solar energy. The whole job was done in half a day. Very happy with the service.”
“Booked an annual service for our 6-year-old solar system. GL Solar cleaned the panels, checked all the electrics and gave us a detailed performance report. They spotted a loose connection we didn't know about and fixed it on the spot. Great value and very professional.”
“My solar system was installed by a company that has since gone out of business. GL Solar took over the maintenance and did a thorough health check. They found the inverter was underperforming and replaced it — my generation has increased by 15% since. Excellent service.”
“We needed a consumer unit upgrade before our new solar and battery system could be installed. GL Solar handled everything — the electrical upgrade, solar installation and battery all in two days. Seamless service from start to finish. Highly recommend.”
“Had a Hypervolt EV charger installed by GL Solar. The electrician was punctual, tidy and explained everything clearly. The charger works perfectly and the app is great. Very competitive price and excellent workmanship. Will definitely use GL Solar again.”
