SunPower Solar Panel Installation

Let us show you how Sunpower solar panels can save you money, give you more energy independence and cut your carbon footprint.

We install Sunpower Solar Panels across Melbourne

  • Efficiency - Sunpower solar panels use anti-reflective glass to absorb more light and generate more energy. While solar panels generally work best on sunny but mild days, Sunpower panels can deliver more energy at higher temperatures and in partial shade.

  • Warranty - Sunpower backs its solar panels with an outstanding 25-year Complete Confidence warranty. It’s no wonder the company has such confidence in its product. Sunpower’s Performance P19 solar panels were named a top performer in the 2018 DNV GL PV Module Reliability Scorecard.

  • Durability - Sunpower has re-engineered conventional solar technology for greater energy output and savings. With added strength and enhanced performance, the Sunpower panel uses proprietary encapsulants to protect the solar cells and minimize degradation from environmental exposure, extending the life of their panels.

Customer feedback

  • Lynne Tolmay

    “I was given a personal reference to use this company. This company is socially aware. After talking on the phone, I knew this was the company for me. They were knowlegable, honest and helpful. They asked me questions about my property, my electricity consumption and my expectations of having solar panels. They explained the pros and cons of different panels and pointed out the benefit of a really good converter. I’m not familiar with the bits and pieces of solar, but I didn’t have to worry, because everything was explained in a way that I could understand. An installation date was set and they arrived when they said they would. They were prompt and professional. They worked quickly and I had my system up to go in two days. They were polite and friendly. They cleaned up after themselves. They contacted me two weeks after the installation to see if I was happy with how the system was going and if I had any questions. I would very highly recommend Solar Flow.”
