2. REC Alpha Pure Series

Scandinavian quality with a 25-year warranty. Founded in Norway in 1996, REC Group is recognised for producing high-quality solar panels with long warranties and excellent reliability.

REC Alpha Pure panels feature REC’s innovative design, with high panel efficiency & power output thanks to top-quality monocrystalline cells. This enables you to get more out of the space available on your roof – helping to lower your energy bills and shorten the payback time through increased yield and lower costs.

Choosing a top-of-the-range panel such as the REC Alpha Pure panel is an investment in superior standards of design, manufacture, support and customer service. This high-quality results from REC Solar’s strong commitment to developing a module that delivers reliable, high output for decades.

REC solar products are rigorously tested beyond industry standards, and those standards apply equally when selecting materials for their solar modules. When you choose REC Solar, you’ll have peace of mind that you are buying the best.

The best news of all is the price. REC Alpha Pure panels are extremely well-priced for such a quality panel. REC Solar is striving for industry-leading efficiency. However, critically they incorporate this new technology into their production line to ensure all customers have access to the best technology available. It’s not much use if a company releases a new high-efficiency panel (with a lot of publicity) but only makes 1000 of them and/or charges an absolute fortune for them.

3. SunPower Maxeon 6 Series

SunPower has recognition as a global leader in top-quality solar panels since 2007. They’ve had many successful releases over the decades, predominantly in the United States. In Australia, SunPower has a reputation for absolute quality, perhaps the best on the market. However, their panels have always come at a high price point.

The top-of-the-range Maxeon panel is no exception. It is a top-quality panel that comes with an astonishing 40-year warranty. That’s enough to outlast the competition (and perhaps a few of us as well) – by decades.

4. Q Cells QPeak DUO Series

1KOMMA5° previously installed Q Cells panels when they were based in Germany. We are excited to once again have Q Cells panels in stock, with the premium QPeak Duo panel as our premium offering.

With a higher efficiency rate than the previous series, the Q.PEAK DUO G10+ panel is the first 400W module from Q Cells for Australia’s residential market and takes high performance to a new level.

The G10+ module utilizes Q CELLS’ zero gap Q.ANTUM DUO Z technology to boost module efficiency up to 21.4%. The module is also backed by a 25-year product and performance warranty that guarantees at least 86% of nominal power up to 25 years.

Innovative All-Weather Technology helps to provide increased yields, whatever the weather with excellent low-light and temperature behaviour.

REC Solar Panel Twin Design

In Australia, there are a number of solar batteries brands available but based on our experience, we only recommend two best ones based on their performance, warranty and price.

The Top 5 Best-Value Solar Panels in Australia

We have typically seen all of the big Chinese manufacturers offer a top-quality panel designed specifically for the Australian market. These panels are normally quite similar in terms of price and output, and even most of the technical specs will be the same.

1. Trina Solar Vertex S+ Panel

Trina Solar has once again been voted number #1 by Australian Solar Installers as making the best-value solar panel in Australia. In 2024, this is the Trina Vertex S+ module.

Trina is the largest vertically integrated solar manufacturer. That means they manufacture all the key components from ingots to completed modules. Trina not only performs large-scale solar Research and Development around the world, but they also have teams of scientists working on energy-efficient product research in many of the world’s leading universities. For example, the Australian National University and the University of Queensland.

Trina Solar Panels were selected for Australia’s largest rooftop installation – an enormous 1.22MW array (5,004 panels) – for the University of Queensland. This facility not only provides a significant proportion of the campus’ power but is also used as a testing ground for ongoing research.

Trina Solar Panels are positioned at the premium end of the available Chinese panels. The Trina Vertex S+ panel is considered by many industry experts to be the best-value solar panel made by a Chinese Manufacturer.

Trina solar panels are designed and manufactured to the highest quality standards, and the products have proven themselves in the field and third-party testing against other leading manufacturers. This, combined with its high performance under low light conditions, allows for consistently high output and the ability to maximise system performance.

Trina Vertex Technical Details

Overall, Trina has an exceptional track record and has long led advancements in solar technology. This new 430W module is setting a new standard in Australia for high performance at a great price point.

The technical highlights of this high-performance panel include:

  • Doulbe-glass + innovative non-destructive cutting for improved mechanical resistance and strength. They are less prone to micro-cracks and scratches on the back during installation.

  • Trina Vertex panels have a guaranteed power tolerance of +5W, meaning that the flash test output may be as high as 435W rating. However, this additional output is only beneficial if you install a system with panel-level output, such as an Enphase Micro Inverter solution.

  • Trina Vertex S+ panels will maintain a minimum of 87.5% power output after 30 years. They also have a 22% module efficiency with high-density interconnect technology.

2. QCells

QCells was voted by Australian installers to be among the top 5 companies that provide good-value solar panels. This is a great achievement as the ‘budget’ QCells Q.Boost panel is a step up in price compared to the likes of Trina and Jinko.

Q.BOOST is a high-tech solar module designed with Q.ANTUM DUO Z Technology and a zero-gap cell layout (similar to the top-of-the-range panels) to boost module efficiency by over 21 %.

3. REC Solar TwinPeak 5

On a standard-sized residential system, a REC Solar System with premium TwinPeak 5 panels is only around $1000 more than a standard solar system (with generic Chinese solar panels). This makes the REC panel one of the best value options on the Australian market, considering its high level of performance, reliability, and output in shaded conditions.

As a Certified REC Installer, REC Systems installed by 1KOMMA5° feature an extended 25-year product warranty as well as a 25-year power output guarantee.

REC TwinPeak 5 features REC’s innovative design with the high panel efficiency and power output of monocrystalline cells. This helps lower energy bills and shorten the payback time through increased yield and lower costs.

REC TwinPeak 5 panels are packed with the same advanced REC TwinPeak technologies that have won REC multiple awards. This p-type mono variant offers higher power output per square meter of panels installed.

4. JinkoSolar

JinkoSolar is one of the world’s largest solar panel manufacturers and has a long history of supplying good quality solar panels to the Australian market at a great price.

The new generation of solar panel technology has been featured in the N-type cells in the Tiger series. Following on from previous years, Jinko is once again firmly in the mix for offering a good value panel for Australian households.

5. Canadian Solar

Canadian Solar is like Trina and Jinko. They are a global leader that makes high-quality panels at a great price for the Australian market.

Importantly, all Canadian panels that hit the Australian market are made in Asia. However, the company still has strong ties to Canada.

What About Solar Panels Made in Australia?

Tindo Solar is currently the only large Australian solar panel manufacturer and one of the only large manufacturers that has yet to move to Asia.

Tindo Solar is well-regarded by the Australian Solar Industry. It will likely play an important role for solar energy in Australia, depending on the stability of supply chains as the world emerges from the Covid crisis.

Tindo’s home is in South Australia, and its production volume is fairly limited. Because of this, Tindo Solar panels can be a little difficult to source here on the East Coast.

Enphase Components

What's the Best German-Made Solar Panel?

German companies are renowned for their high manufacturing standards, and this was particularly true in the solar industry a few years ago.

Buying a panel from a company such as QCells or Solar World was a reliable way of ensuring you were buying a quality system without delving into the mysterious world of Chinese solar manufacturing to try and differentiate one panel from the next.

Unfortunately, however, all of the main German manufacturers are now either making their panels in Asia or do not have a local office here in Australia.

The 1KOMMA5° Group has taken matters into our own hands by manufacturing our own panels using German Polysilicon and then assembling our panels in China to industry-leading quality standards. This allows us to manufacture a solar panel without forced child labour. we have significantly reduced the panel's CO2 footprint, with the panel paying back its energy footprint in well under one year.

Unlike the bad old days of the Australian solar industry, we aren’t here claiming we have a panel with a ‘German design’ and then just making it in China. This is a serious step forward where we balance ethical supply chain management and industry-leading quality at an affordable price point.

Solar Panel Performance Isn't Always As It Seems

An independent study by CSIRO for Choice Magazine tested one panel from 15 of the most common solar panels available in Australia. During the test, they found that 12 out of the 15 panels performed under their claimed nominal power, some by as much as 10W.

Because only one panel was used in the test, it is impossible to draw strong conclusions about certain brands. However, it certainly drew attention to the fact that there are some large inconsistencies between a manufacturer’s claimed nominal power and real-world output.

For example, a 260W panel from one of the largest manufacturers in China scored a test result of 251W. This inconsistency highlights just how critical it is to have access to panel-level output and monitoring, which is a feature of Smart Solar Systems.

Solar Panels are Manufactured with a Power Tolerance

Each manufacturer is different. However, the better brands tend to have a +3% range. The only way to take advantage of this is to use a system such as Enphase that features panel-level output, otherwise, you will output power at the rate of the worst-performing panel in your array. At best this will be at the panels’ rating, at worst it may be much less.

Output in low light conditions is also critical in Sydney due to our weather. We only get around 100 ‘perfect’ days a year, the rest have some rain on our cloud cover. The better panels (such as the panels listed below) not only perform well in the testing laboratory, but they also output more power across the year in all weather conditions. Increased output in low light conditions can make a significant difference to your power bill over the years.

Manufacturer’s Financial Strength & Local Representation

Cheap solar panels are pumped out of China at a dime a dozen. They are often rebranded with a slick logo or simply shipped to countries like Australia and sold without a brand at all! Have you ever seen a quote for “20 x 300W solar panels”? We see it all the time. It is literally a no-name system!

Cheap solar panels can often have no claimable warranty despite the marketing claim of a full 25-year Power Output Warranty.

Often, there will be a phone number that no one answers or contact details for an office in China where no one speaks English. Furthermore, if it wasn’t brought into Australia through an official distributor, the warranty is lost if the manufacturer goes bust (or simply changes its name).

For the warranty to be of any value, the product must come through official distributors, and the manufacturer must have an office in Australia. The company must also be in a strong financial position and committed to the Australian market.

In fact, it is such a problem that it’s estimated a huge 1 in 3 solar systems in Australia have no support!
