We carry out solar panel installation across Cardiff and all CF postcodes, from Canton and Roath in the west to Llanishen, Cyncoed and Pontprennau in the north, including homeowners on the border of the Vale of Glamorgan.
Every installation is managed end-to-end by our own team. From your first survey to the day we hand over your system, there are no subcontractors, no hidden costs and no pressure to commit before you are ready.
"John, Luke and the rest of the lads (even the scaffolders that were needed) were absolutely fantastic from start to finish and the battery system that was fitted is brilliant. The sales process and workmanship were both first class. I've made significant savings on my bill too! They even fixed the solar panels that I already had when a squirrel had chewed through the wires! So I would highly recommend Quantum Renewables for any of your solar needs" Dave powell cf38

“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
