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


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.


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.


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.

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.

The team did a fantastic job advising us and then installing our solar PV system. The work was done efficiently and to spec, and we're delighted with the results. That follows on from work Alex and his team did installing our heat pump water heater in 2018. The panels now run the heat pump, saving us power bills and cutting our household CO2 emissions. Cannot recommend highly enough.

All you should know about Solar panels

Solar panels are panels that absorb energy from the sun for the purpose of converting it into electricity that can be used to power your property. They are typically placed on the roof of the property in order to have the most exposure to the sun throughout the day.

Solar panels work by absorbing sunlight and transforming it into electricity through a process called photovoltaic. Photovoltaic cells are placed on the panels, which capture the energy from the sun and convert it into energy that can be used to power your home’s appliances. This process is completely safe, clean, and easy to maintain.

Solar panels can help to reduce the overall energy usage and costs of your home. By installing solar panels, you can save up to 50% on your electricity bills, which is a significant amount of money over the long term.

Solar panels are also significantly cleaner than traditional energy sources. They do not produce any harmful emissions, and are not dependent on any fossil fuels. This makes them a great choice for the environment, as well as for your budget.

There are few drawbacks to installing solar panels. The main downside is the initial cost, which can seem like a large expense at the time. However, after the initial installation, the cost savings that you will see in your electricity bill will make for a worthwhile investment in the long run.. Solar panels are also more complex to install than traditional types of energy, and it requires a professional to install them. However, the process is quite simple after the panels have been installed, and with a 25-year warranty, you can all but forget them and enjoy the many benefits they bring to your home or business.

There are a few ways that you can save money with solar panels. By installing solar panels, you can reduce the amount of energy that you use from the grid, which will save you money. Solar panels are also very durable and will last for several decades, so you will continue to save money with them for a long time.

We install solar panels from leading manufacturers like LG, Jinko, Trina, and Sunpower. We’ll recommend the brand and type of photovoltaic cell/solar cell/panel that suits your unique circumstance, residence, and budget/cost.
