The Best Solar Panels In 2024: According To Aussie Installers

It’s that time of the year again when I reveal the results of our annual Installers’ Choice Awards for Best Solar Panels in 2024. With insights from installers across Australia, I asked them three crucial questions to discover which solar panels they rate as the best in the business for 2024:

  • What brand of solar panels would you buy for your own home if money was no object?
  • What about if you were on a budget, and every dollar counted?
  • What brand has the best after-sales support?

So, let’s uncover which brands have outshone the competition in the eyes of those who know them best – the installers.

Best Value Solar Panels In Australia: 2024

In the highly competitive “Every dollar counts” category, we look for panels offering the best bang for your buck without compromising on quality. This year’s winners have proven exceptional performance and affordability can indeed go hand in hand:

About Finn Peacock

I'm a Chartered Electrical Engineer, Solar and Energy Efficiency nut, dad, and the founder and CEO of I started SolarQuotes in 2009 and the SolarQuotes blog in 2013 with the belief that it’s more important to be truthful and objective than popular. My last "real job" was working for the CSIRO in their renewable energy division. Since 2009, I’ve helped over 700,000 Aussies get quotes for solar from installers I trust. Read my full bio.


  1. And Trina won places despite the horror warranty stories exposed by this site’s own blog?

    • Finn Peacock says

      The installers vote based on their experience; we have no input. The examples of poor warranty service seem rare enough to not override installers’ good experiences with Trina in Australia.

  2. Any chance of having a reliability and efficiency study of panels after say two or five years? Problem with installers opinions is they don’t actually see them working and have information about reliability.

    • Finn Peacock says

      These are installers who also sell the systems – and thus are responsible for the 25 year plus warranties. They won’t sell panels that they don’t trust or know to be reliable over decades.

      • But how often do the people who sell and install the panels come back to check on their efficiency and physical longevity?

        A poll of about a dozen others who I know with solar panels is that they never come back or ring to see how well the system runs. Or come back to see how the panels and electrical plumbing survived the last storm.

        Which are questions just as relevant as how the system looks and screws together when it’s installed.

        The real test of a system is how it maintains its electricity outout and its physical integrity after 10 years out in the weather.

        Maybe a poll of blog followers with these questions in mind would be informative.

  3. Erik Christiansen says

    The 27 kW of REC Alpha Pure 420W panels which went up here last month were chosen almost exclusively because they are lead free. Here, miles off-grid, it’s tank water or thirst, so best not to take chances. It’s bad enough to have a bit of gumleaf taint in two of the tanks, but they can be used for garden watering and fire fighting. Only the latter could tolerate lead pollution. Even city folk, using tank water for a vegetable garden, might give it a thought.

    Finn’s “Fill the Roof” policy is well advised. Even the 23 kW of shadow free arrays currently being insolated yield only 2.3 kW in bright 100% overcast at the moment. But the batteries and EV are full, so it’s going into the HWS. Adequately overdimensioned, there’s enough production for modest consumption on low sun days.

    Yeah, battery for 5 days is good. Array oversize of 300% or more, for indefinite maintenance of base load in overcast, is even better. Both is proving very comfortable – so far.

    We’ve doubtless not seen the last high voltage power pylons flattened like soggy noodles. The famous physicist Svante Arrhenius, in a paper published in 1896, predicted +5 degC global heating for +50% atmospheric CO2. And 425/280 ppm is +52% to date. So +1.77 degC in February is just thermal lag due to 93% of heating going into the oceans. I’ve heard of 30 Mt of Greenland icemelt per hour – that’s about 5 cubic km per week, if I’m counting right on my fingers.

    If not off-grid, then being on a local microgrid with ample battery capacity seems advisable in the coming decades. There is then much less need to spend billions upgrading the network to push rooftop energy back up a pipe not built for that. And when it goes down, there’s less problem with no network power for 5 weeks, like in the Dandenongs in Jun-Jul 2021. (Yup, no lights, no internet, cooking on a camp stove. I bailed out after a fortnight of that. And I had a wood heater. At 600 ft altitude, no luxury in winter.)

  4. Wait what? “Despite Sunpower’s superior panels, their high cost is increasingly difficult to justify”

    I thought it was supposed to be the “Money’s No Object” category?

    Let’s be honest. REC won because they’re cheaper than SunPower, therefore sold by more installers, therefore voted by more installers.

    If we’re talking about just quality / durability / reliability, SunPower Maxeon wins hands down. You don’t see REC cells being used on 90% of the cars in the Darwin-to-Adelaide solar car race. Or racing yachts, or record-breaking solar-powered planes, or NASA!

    And if we also consider ESG practices & metrics, SunPower also wins.

  5. I bought Longi Bifacial 580wat for US $130 This is good price or not?

    • Anthony Bennett says

      $196.47 ÷ 580w = 33c/watt in Australian terms which certainly isn’t expensive.

      • Gerlinde U. Germann says

        Hi Finn. very interesting Reading as I’m looking to install Solar. on my Roof ! So much for.our P.M. Mr. Albenese saying Elec. will become cheaper under his reign Yeah.!!
        Some one. mentioned. “Honeywell ” the German.Panels.?? any comment. & who. is

  6. Can I have a rating on AESOLAR panels – German?

    • Anthony Bennett says

      Hey Whatman,

      I’ve never heard of them but I’m sorry if that doesn’t help. Have they go an Australian warehouse? Serviced office? Proper local website? That will tell you al lot about them.
