Is Your Property Suitable?
South-facing roofs with a pitch of between 30 and 40 degrees receive the most sunlight in the UK, but east and west-facing installations still generate meaningful electricity. An MCS-accredited installer will assess your roof's orientation, shading, and structural condition before recommending a system. Flat roofs can also be used with angled mounting frames.
Costs, Savings, and the Smart Export Guarantee
A typical domestic solar system costs between £5,000 and £12,000 depending on size and whether battery storage is included. Most UK homeowners achieve payback within 8 to 12 years. The Smart Export Guarantee allows you to sell surplus electricity back to the grid — only MCS-accredited systems qualify.
Cardiff is the capital city of Wales and its largest city. Cardiff Castle, in the heart of the city, is a medieval castle and Victorian Gothic mansion. The Principality Stadium hosts international rugby and football matches. Cardiff Bay has been transformed from a derelict dockland into a vibrant waterfront area with the Senedd (Welsh Parliament) and Wales Millennium Centre. Cardiff University is a Russell Group university.
Why MCS Accreditation Matters
Any installer you use should be registered with the Microgeneration Certification Scheme. This is required for Smart Export Guarantee eligibility and also provides you with a meaningful benchmark of installer quality and accountability.
