Solar panels in Cardiff: FAQs
Do you cover Cardiff?Yes. We arrange solar panel and home battery installations across Cardiff and the surrounding areas, including Penarth, Llandaff, Whitchurch, Roath. Every installation is carried out by MCS certified installers, and we cover installations nationwide.
Do I need planning permission for solar panels in Cardiff?Most roof-mounted solar on homes in Wales counts as permitted development, so it doesn't need planning permission. If your home is listed or in a conservation area, we check with Cardiff Council before any work starts.
Who is the network operator in Cardiff?Cardiff is on the National Grid Electricity Distribution network. For systems up to 3.68kW your installer notifies them after installation; larger systems need their approval first, and your installer handles that application for you.
Can you add a battery to my existing solar panels in Cardiff?Usually, yes. Our MCS certified installers fit Fox ESS and Sigenergy batteries to new and existing solar systems. We'll check your current setup during the survey and tell you what's possible.
