GL Solar designs and installs complete home solar energy systems across every Cardiff postcode, from the Victorian terraces of Roath and Cathays to the modern developments in Pontprennau and St Mellons. A complete home solar system means more than just panels on your roof — it is a fully integrated energy solution combining high-efficiency solar panels, a smart inverter, optional battery storage and real-time monitoring into one seamless package.

Cardiff homeowners are seeing exceptional results from complete home solar systems. A typical 4kW system with a 10kWh battery in Cardiff generates around 3,400–3,800 kWh per year and achieves 70–80% solar self-consumption. With energy prices remaining elevated, this translates to annual savings of £900–£1,200 for a typical Cardiff household — with payback periods of just 6–8 years.

As a fully MCS certified installer based in Cardiff, we handle every aspect of your home solar system from the initial energy assessment and bespoke system design through to installation, DNO notification, grid connection and ongoing aftercare. Our Cardiff team uses real South Wales weather data and your actual energy bills to size every system perfectly — no generic estimates, no overselling.
