Llanishen is one of Cardiff's most solar-friendly suburbs, with its predominantly post-war semis, spacious detached properties and excellent south-facing exposure making it ideal for complete home solar systems. GL Solar has installed numerous fully integrated solar energy systems across Llanishen and Thornhill, from 4kW arrays on semis to 8kW+ systems on larger detached properties.

A complete home solar system in Llanishen typically includes 12–20 high-efficiency panels, a smart inverter with monitoring, and an optional 5–13.5kWh battery. Llanishen's elevated position and spacious plots mean many properties enjoy unobstructed southern exposure — a 5kW system generates 4,200–4,700 kWh per year. With battery storage, self-consumption reaches 75–85%, cutting annual bills by £1,000–£1,400.

GL Solar is a local Cardiff installer with extensive experience across Llanishen.

Our complete home solar systems come with a 10-year workmanship warranty, full DNO handling, and ongoing support from a team that's always nearby.
