Swansea is one of the most solar-viable cities in Wales. Properties across SA2, SA3 and the western suburbs benefit from open coastal skylines and strong afternoon sun exposure, while homes further inland across SA4, SA6, and SA7 are equally well-positioned where roof orientation allows. We install across the full Swansea area, from Uplands and Sketty to Mumbles, Morriston, Killay and Gorseinon.
Every installation is handled entirely by our own team. The engineer who surveys your property is involved in designing your system, which means the advice you receive on survey day reflects what will actually be built, not a sales pitch adjusted after the fact.
If you want to see how installations have performed for homeowners across the region, our completed South Wales case studies include verified savings data and real figures from properties similar to yours.
"From the initial survey through to the final handover, every stage was handled with complete professionalism. The savings have been exactly as projected, and the team were a pleasure to deal with throughout." Swansea customer, SA2

“1st Class Service, would highly recommend Quantum Renewables.
Had 24 solar panels, 10KW inverter and 13.5KW battery storage installed a couple of months ago, we couldn’t be happier with the savings seen in our electricity bills since install.
Massive Thank You to Electricians Luke and Dan for the install and John for providing the initial quote.” Janet Howell Maesteg
