Why Homeowners Across South Wales Are Switching to Solar
Electricity costs have risen sharply over the past few years, and most analysts expect that trend to continue. A well-designed solar panel system can cover between 50 and 80 per cent of a typical household's annual electricity use, reducing bills immediately and protecting against future price increases. When combined with battery storage, surplus power generated during the day is saved for evening use rather than sold back to the grid at a low rate.
Quantum Renewables was founded in Bridgend and operates exclusively across South Wales. Every survey, design and installation is handled by our own in-house team, not subcontractors. With over 100 completed installs and an average customer payback period of 7 to 9 years, we focus on giving homeowners accurate expectations before any commitment is made.
A Process Built Around Transparency
We start with a free property survey using local irradiation data to calculate your projected savings based on your actual roof, not national averages. Most installations are completed in a single day by our NICEIC-approved electricians, and we handle all MCS registration and grid connection paperwork on your behalf. MCS registration is required to access the Smart Export Guarantee, which allows you to earn money by selling unused electricity back to the grid.

Credentials That Protect Your Investment
Quantum Renewables holds MCS accreditation, NICEIC approval, Trustmark registration and RECC membership. Every installation includes a 2-year insurance-backed workmanship warranty through IWA, alongside 25-year panel performance guarantees and 10-year inverter warranties from the manufacturers.
We are approved installers for Enphase microinverters and GivEnergy battery systems. If you have an existing solar system fitted by another company, we also carry out battery storage retrofits to improve what you already have.
