What's different about Wales
Coastal and rural Wales has plenty of unshaded roofs and a high share of detached and off-gas properties, which is where solar plus battery tends to make the strongest case. Exposed sites need attention to fixings and wind loading at survey.
Installers quoting in Wales usually cover Cardiff, Swansea, Newport, Wrexham, Bangor and Aberystwyth. If an installer doesn't routinely work in your postcode, travel and return-visit costs tend to be built into the price — which is exactly why we match on postcode first.
What moves your quote up or down
- Roof pitch, orientation and shading — South-facing, unshaded roofs need fewer panels for the same output. Shading from trees or chimneys often means optimisers, which adds cost.
- Scaffolding and access — Terraces, three-storey homes and restricted access all add scaffolding time — a common reason two quotes differ.
- Panel and inverter choice — Premium panels and hybrid inverters cost more upfront but can be worth it if you plan to add a battery later.
- Adding a battery — Fitting a battery at the same time as solar is cheaper than retrofitting later, because the inverter and labour are shared.
How to compare quotes in Wales
Get at least three quotes from installers covering your postcode and compare them line-by-line rather than on the headline price. Our Solar panel costs UK guide explains what each line on a quote actually means.
