Solar Panels in Cardiff

Cardiff's mix of Victorian terraces and modern suburban estates gives a wide range of roof pitches and orientations that suit photovoltaic arrays. Most properties have enough unshaded roof space to generate a meaningful portion of their electricity demand.

The city's temperate maritime climate delivers consistent daylight throughout the year, so panels keep producing even in winter months. Combined with low degradation rates, a system installed today will still be delivering strong output after two decades.

The UK‑wide ECO4 programme can cover the full cost of a solar installation for households that receive qualifying benefits, and the 0 % VAT rate on panels and batteries runs until 31 March 2027. In Wales the Nest Wales scheme offers additional advice and funding pathways for eligible homes.

Any exported electricity is paid for under the Smart Export Guarantee, but only MCS‑certified installers can register a system for SEG payments. Choosing an MCS‑approved contractor therefore protects both your income stream and any grant eligibility.

Enter your postcode in the short form on this page and we will match you with MCS‑certified installers who operate across Cardiff and the surrounding valleys. The quote process is free, carries no obligation, and gives you a clear picture of system size and expected performance.
