Solar Installation in Cardiff
Cardiff offers strong potential for solar energy generation. UK solar irradiance levels, combined with falling panel costs and the Smart Export Guarantee, make solar a sound investment for homeowners and businesses across the city. A typical 4kW system generates between 3,400-4,200 kWh per year depending on roof orientation, pitch, and shading. South-facing roofs with a 30-35 degree pitch deliver the best performance.
When choosing a solar installer in Cardiff, look for MCS certification as a baseline requirement. This ensures the installation meets industry standards and qualifies you for the Smart Export Guarantee. Check installer reviews, ask for references from local projects, and compare at least three quotes before committing. Many installers in Cardiff also offer battery storage and EV charging solutions, allowing you to maximise your solar investment.

Who is the best solar installer in Cardiff?
The best solar installer in Cardiff depends on your specific needs, budget, and project type. Check installer ratings, reviews, certifications (especially MCS), and years of experience on this page. We recommend getting quotes from at least three installers to compare pricing and service.
How long does a solar panel installation take?
A standard residential solar installation takes 1-3 days for the physical installation work. However, the full process from initial survey to commissioning typically takes 4-8 weeks, including site assessment, design, scaffolding, installation, electrical connection, and DNO notification.
Do I need planning permission for solar panels in the UK?
Most residential solar installations in the UK fall under permitted development and do not require planning permission, provided the panels do not protrude more than 200mm from the roof surface and are not installed on a listed building or in a conservation area. Commercial installations and ground-mounted systems may require planning approval.
