Paul Degrasis
Home Installation
Smashing. We wanted to add battery storage to our existing solar panels and Zappi EV charger, and Quanta recommended and installed the myenergi Libbi 10kW system—all in a day. They also upgraded our inverter and fitted a fire-resistant mounting board. Everything was explained clearly, and the work was neat and professional. It’s clear Quanta is up to speed with the latest in solar, battery, and EV tech. If you're thinking of investing in a setup, I’d absolutely recommend giving them a call—honest advice and great service.

Our solar system failed recently. Quanta responded very rapidly, tested the system & fitted a new inverter. Excellent workmanship and very pleasant service. We are pleased to endorse his work.
David Garden
Home Installation
Quanta came highly recommended, and they delivered a smooth, professional installation of our solar panel and battery system. Charlie and Jack were punctual, hardworking, and left everything neat and tidy. Charlie took the time to explain how the system works, including how we can export excess energy back to the grid. We’re really pleased with the result and would happily recommend Quanta to anyone considering solar.
