none of those things happened.\u00a0 The reason why the illustration of their solar cell has no busbars is because it isn&#8217;t their cell.\u00a0 It&#8217;s actually a picture of a SunPower Maxeon solar cell and they just took\u00a0the image and changed the text.\u00a0 Here&#8217;s the SunPower page it <a href=\"https:\/\/www.sunpower.com.au\/home-solar\/solar-cell-technology-solutions\/\" target=\"_blank\" rel=\"noopener\">originally came from<\/a>.<\/p>\n<p>That&#8217;s pretty bloody cheeky of them, taking\u00a0the image of what is possibly the best cell available and passing it off as their own.\u00a0 I have to give OneSolar 10 out of 10 for balls, but since they&#8217;re not actually in the business of selling testicles, I have to give them 0 out of 10 for being a business you can trust.<\/p>\n<p>Actually, with the track record they&#8217;ve established, I wouldn&#8217;t be surprised if they mine this article for quotes and use the following as a testimonial:<\/p>\n<blockquote><p>SolarQuotes\u00ae \u00a0: &#8220;I have to give OneSolar 10 out of 10&#8221;<\/p><\/blockquote>\n<h2>Panels, Inverters, And Storage, Oh My!<\/h2>\n<p>On their Australian site they have one inverter they call the Power Qube.\u00a0 I don&#8217;t know what it was originally called when it was made in an unknown factory, but Power Qube is what they have rebranded it as.<\/p>\n<p>If you are interested in it, I can recommend a good manufacturer of 12 foot poles on account of how I wouldn&#8217;t touch it with a 10 foot one.<\/p>\n<p>While I strongly suspect\u00a0their inverter was made in China, they completely fail to mention where it is made.\u00a0 Their Power Qube page has the following phrase frequencies:<\/p>\n<ul>\n<li>&#8220;German quality standards&#8221; &#8211; 4 uses<\/li>\n<li>&#8220;German and US engineering&#8221; &#8211; 1 use<\/li>\n<li>&#8220;Made in Germany&#8221; &#8211; 3 uses<\/li>\n<li>&#8220;Made in USA&#8221; &#8211; 3 uses<\/li>\n<li>&#8220;Made in Japan&#8221; &#8211; 2 uses<\/li>\n<li>&#8220;Made in Netherlands &#8221; &#8211; 1 use<\/li>\n<li>&#8220;Made in Austria&#8221; &#8211; 1 use<\/li>\n<li>&#8220;Made in China&#8221; &#8211; 0 uses<\/li>\n<\/ul>\n<p>If you are wondering how it could manage to be made in so many different countries that aren&#8217;t China, OneSolar has an image of the internals of their inverter that displays how 10 of its components are definitely not made in China.<\/p>\n<p>But this doesn&#8217;t mean anything, as I could open up the cheapest inverter I could buy and find components in it from around the world.\u00a0 That&#8217;s how modern supply chains work.\u00a0 They allow factories to use the cheapest components no matter where they&#8217;re made.<\/p>\n<h2>China Don&#8217;t Get No Respect<\/h2>\n<p>Personally, I find it pretty tacky how a German based company can mention 6 different countries on its inverter page, but not the actual country it was made in.<\/p>\n<p>I am not saying the German based OneSolar company is as prejudiced\u00a0as my Grandfather on ANZAC day after he&#8217;s polished off a bottle and a half of whiskey.\u00a0 I&#8217;m just saying they don&#8217;t seem to want to give China any credit.<\/p>\n<h2>The OneBattery System<\/h2>\n<p>The Australian OneSolar site has a page about their OneBattery energy storage system and I have to say I was was very impressed by its almost complete lack of information.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-9908 size-full\"

that is pretty bloody amazing.\u00a0 I&#8217;ve been writing about battery systems for years now and I never would have expected the market leader to turn out to be a system I have never heard of before.\u00a0 That&#8217;s totes amazeballs.\u00a0 I can state quite confidently, without any fear of contradiction, that my amazeballs have never been more toted.<\/p>\n<p>All I can say is, they must be using some bloody good stealth technology.\u00a0 No doubt one day soon they will flick a switch and all these OneSolar battery systems we didn&#8217;t know were installed will uncloak and everyone will be able to clearly see they are the market leader.\u00a0 This will be quite unlike the situation we have today where they just appear to be making stuff up.<\/p>\n<p>But I do have to give credit where credit is due.\u00a0 OneSolar has solved a major problem of wall mounted battery systems, which is the best way to attach a system to a wall.\u00a0 Normally there is a lot of mucking around with drills and bolts and frames and screws and things, but OneSolar has done away with all that.\u00a0 Their solution is so simple it&#8217;s brilliant.\u00a0 They just photoshop it to the wall.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-9589\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2017\/02\/onebattery.jpg\" alt=\"Photoshop makes

Australian site OneSolar doesn&#8217;t give any warranty information for their solar panels.\u00a0 But they do state they have a 12 year warranty for their Power Qube inverter.\u00a0 This is the longest warranty I know of for a <a href=\"https:\/\/www.solarquotes.com.au\/glossary.html#stringinverter\">string inverter<\/a>.\u00a0 Even Fronius, which makes some of the best inverters available, currently only offers a f<a href=\"https:\/\/www.fronius.com\/en\/solar-energy\/installers-partners\/service-support\/warranty-conditions\">ive year warranty<\/a> plus an additional 5 years for parts.\u00a0 [<em>Update 17th March:\u00a0 I overlooked SolarEdge which has a 12 year warranty on their inverters.]<\/em><\/p>\n<p>But if you think 12 years sounds impressive, just wait until I tell you that in Europe OneSolar offers a 20 year warranty.\u00a0 That is astounding.\u00a0 Those Chinese factory workers must be doing a hell of a job to make such a reliable inverter.\u00a0 Such a good job that you&#8217;d think they&#8217;d deserve some credit for it, wouldn&#8217;t you?<\/p>\n<p>I have no information on how reliable OneSolar&#8217;s inverter&#8217;s are.\u00a0 For all I know they could be better than those of all the leading manufacturers and will last for decades without problems.\u00a0 But it would be remiss of me if I did not state that I strongly doubt this is the case.\u00a0 My spider senses are definitely tingling on this one.<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/onesolar-review-one-word-avoid\/#en-9427-4' id='enref-9427-4'

glossy brochures with lashings of photoshopped images, and claims that their rebranded cheap Chinese panels or inverters are somehow equal to or better than the very best on the market.<\/p>\n<p>There are a few common warning signs to look out for if you want to avoid these brands:<\/p>\n<ul>\n<li>They give the impression their panels are made in Australia but they are not <a href=\"https:\/\/www.solarquotes.com.au\/installer-review\/tindo-solar\/\">Tindo<\/a> panels, which are the only ones made in this country.<\/li>\n<li>They talk a lot about &#8216;German Engineering&#8217;.<\/li>\n<li>They claim their panels or inverters are as good as or better than the best currently on the market.<\/li>\n<li>The only information about their panels and inverters you can find online comes from their own website.<\/li>\n<li>The companies selling them use door to door salespeople.<\/li>\n<\/ul>\n<p>To get a reliable system that will deliver low bills for decades we strongly suggest the following:<\/p>\n<ul>\n<li>Use only Tier 1\u00a0solar panels or Tier 2 ones that are known to be reliable such as Tindo Solar or Opal solar panels.<\/li>\n<li>Use a well known\u00a0brand of inverter.<\/li>\n<li>Use a reputable installer who has proven themselves to be trustworthy.<\/li>\n<\/ul>\n<p>You can find out which panels are reputable\u00a0and which inverters
