6.6kW Solar System



Our 6.6kW solar system makes an ideal match for moderate-sized families looking for the most reliable residential solar power systems in Brisbane and the North gold coast. With the 6.6 kW solar system in Brisbane, we are putting our best foot forward in installation, warranty, durability, energy savings, affordability, conversion efficiency, and post-installation support.

With Queensland's wealth of solar energy and SFR Electricals’ expertise, all you need is a 6.6kW solar system for your residence. 

Some technical specifications for a 6.6kW Solar system:

  • Solar Panels: 20 X 330W Mono-Crystalline Tier 1 Solar panel
  • Inverter- 1 X 5kW
  • Mounting and Electrical Kits as per Australian Standards


Our widely accepted package- the 6.6kW residential solar system in Brisbane, along with the 5kW inverter, typically generates 27.7kWh of electricity per day. The average dimension of the panels is about 1.69 m X 1m. Thus, a 20 solar panel system will occupy a roof area of 34m2. 

Crafted with utmost excellence, our high-efficiency solar panels deliver excellent weak light energy output and come with a 25- year linear performance warranty. The system can save you up to $1600 annually, depending on the tariff you pay to your electricity retailer, panel location and daytime energy usage!! 


If solar panels are the heart of a solar system, then inverters make the brain. And we ensure that the brain of your solar power system is optimized for its assigned functionalities. The 6.6kW solar system in Brisbane is coupled with a 1 X 5kW dual string solar inverter with an optional online monitoring app. This app will display your solar panels' graphic representation and performance and the system's power output daily.

We only use electrical fixtures a class IP 65 ratings that offer a greater protection level in dusty and wet environments. Similarly, you will find uncompromised quality standards for the racking system. They are manufactured from superior grade, corrosion-resistant aluminum.

CEC accredited Solar electricians who are rigorously trained in this field perform the installation.


Why the 6.6kW solar system in Brisbane?

Because moderate to large households need a solar system that meets these requirements simultaneously- overcome ever-rising electricity prices, fulfil power demand, and render full advantage of the government solar rebate scheme. Our typical 6.6kW solar system comes with 20 x 330W solar panels and a 5kW inverter that generates power during weak light conditions and allows you to claim around 33% more solar rebate than a 5Kw solar system.

Plus, the 6.6kW solar system meets the approval process export permission requirements of most of the network providers.

Our experience tells us it is wise to choose as many panels as your budget and roof space allows rather than adding panels to an existing solar system later on, which is a costly affair.

What is the average payback period for a 6.6kW solar system?

Our efficient solar system will start giving you ROI between 3 to 5 years. However, a typical payback period for different households is decided by energy consumption during daylight hours, the energy efficiency of electrical appliances used in the house, 

The rule of thumb is to shorten your payback period by relying more on the solar power system than your electricity grid. Because, based on retailers, the current feed-in tariff ranges between 6c to 15c for every kWh of electricity. But for every kWh of electricity you draw from the grid, you pay four times the feed-in tariff.

If you harness a maximum amount of solar energy for your daytime usage, then you draw less electricity from the grid and eventually reduce the payback period.

A word of caution: You might be tempted to zero in on lower price points installation to increase your returns. But your moment of truth comes while considering only the best quality products and installers, even if some deals appear to be too good.

Why is it important to choose the Australia-based parts for a solar system?

Most often, solar installation parts and products come with a warranty of 25 years. If any of these parts need repair or replacement, warranty claims will be challenging and expensive if the supplier is based outside Australia. Hence, it is better to opt for an installer who affiliates with manufacturers having a solid local presence.

Through years of experience, SFR electrical has established a long-lasting relationship with leading manufacturers of panels and inverters. All of them are readily available in Australia.

What are Tier-1 solar panels?

It is easy to limit your solar power system performance and financial returns by choosing substandard solar panels. The best way to ensure optimum output is to choose tier-1 solar panels. Solar panel manufacturers are ranked into tiers ranging from 1 to 3, with Tier-1 solar panels being the most reliable.

SFR electricals is one of the very few installers in Brisbane that installs only Tier-1 solar panels and manifests its commitment to quality.

Which factors can affect the actual energy output of my 6.6kW solar system in Brisbane?

Well, Brisbane being a sunshine city, a good quality 6.6kW solar system receives an average of 4-5 hours of daily sunshine and is expected to produce electricity approximately between 24kW – 26kW per day. However, these figures vary based on various factors, viz location, local climate, weather, shade from surrounding trees and buildings, orientation and tilt angle of panels, wear and tear, quality of individual components etc.   

What is the ideal solar panel direction?

The direction that positions solar panels to produce maximum is the ideal direction, which is north-facing in Australia. A north-facing solar panel will generate the most energy, with its highest production in the middle of the day.

However, northeast and northwest-facing roofs are also being preferred because they deliver energy only slightly lesser than the north-facing panels.

Nonetheless, East-West facing installations can also work if the families’ energy usage patterns align closely with the solar power generation from earlier in the day till later in the afternoon. In such a case, even if the overall energy production is minor, almost all of it is self-consumed.

How can I get my 6.6kW solar power system to deliver the maximum energy output?

We recommend you undertake solar panel cleaning and solar panel maintenance at least once a year—another way to maximize your return from the solar investment with maximum self-consumption.

And lastly, only trust the best solar panel installer in Brisbane - SFR Electrical.
