The Best Solar Panels To Install In Australia in 2020

The Best Solar Panels For Australia In 2020

Chosing the right solar panels has never been so important.

  • In 2013 there were 454 solar panel manufacturers operating in Australia
  • In 2019 there were only 67!
  • In 2013 there were 26,672 panels in Australia registered with the CEC
  • In 2019 there were only 2650!

The good news is that out of these 67 manufacturers, there are only a small handful that group together at the top of the industry, with the clear standout being LG Solar. LG has been voted the best solar panel in Australia 4 years in a row by the solar industry:

The Best Solar Panels in 2020 Output More Power

The best solar panels in 2020 will output more power than their rating.

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 monitoring, which is a feature of nearly all Solaray installations.

The star performer in this test was LG Solar; their 300W panel produced a test result of 307W. This is in line what we have seen from our LG Solar systems installed across Australia and emphasises the importance of buying good quality panels.

Solar panels are manufactured with a power tolerance

Each manufacturer is different, however, the better brands tend to have a +3% range. For example, a 355W panel from LG Solar will be anything from 355W up to 365W. The only way to take advantage of this is to use a system such as Enphase that features panel-level output, otherwise, you will be outputting 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 our cloud cover. The better panels (such as the panels listed below) not only perform well in the testing laboratory, 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 re-branded with a slick logo, or they are simply shipped to countries like Australia and sold without a brand at all! Have you ever seen a quote for “20 x 250W 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 their name).

For the warranty to be of any value, the product must be supplied 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, it is estimated a huge 1 in 3 solar systems in Australia are unsupported, which has created quite a scene on social media:

This is why Solaray only supplies panels from the top handful of manufacturers, and why we have a strict vetting process before we bring a new brand in for our technical team to begin testing.

The Best High-Efficiency Solar Panels

LG NeON 2 355W Panels

lg-panels-neon
LG is a world leader in solar panel manufacturing with over 20 years of experience. The latest NeON 2 355W panel and the new 370W NeON R panel are packed with the latest technology that gives households improvements that really matter, from longer warranties and higher efficiency to stronger framing and increased wind loading.

Choosing a top of the range panel such as the LG NeON 2 is an investment in superior standards of design, manufacture, back up support and warranties. This high quality is the result of LG Solar’s strong commitment to developing a module that delivers reliable, high output for decades.

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

Very few panels of this quality are available for residential installations, making LG Solar the stand out choice as the leading brand in Australia. LG Solar offers full warranty support and has local representation, and all LG systems installed by Solaray include our Platinum Service Package, which includes full replacement warranties and technical support.

The best news of all is the price – NeON 2 355W panels are extremely well priced for such a quality panel. LG Solar are striving for industry-leading efficiency, but 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 355W panel (with a lot of publicity) but only makes 1000 of them and/or charges an absolute fortune for them.

LG Solar was ranked as the number 1 panel in Australia by Choice Magazine in an independent test by CSIRO. They ranked number 1 for real-world output and the only panel to achieve an ‘excellent performance’ rating.

Trina Honey 330W Panels

Trina is the world’s largest manufacturer of solar panels and is the largest vertically integrated one – meaning they manufacture all the key components from ingots to completed modules.

Trina not only perform large-scale solar Research and Development around the world, they also have teams of scientists working on energy-efficient product research in many of the world’s leading universities – including the Australian National University and the University of Queensland.

Recently, 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.
