This is the fault of <a href=\"https:\/\/www.solarquotes.com.au\/blog\/perc-solar-panel\/\">PERC panels<\/a>. PERC solar panels, which are now very common, can suffer from a form of deterioration known as <a href=\"https:\/\/www.solarquotes.com.au\/blog\/perc-solar-panels-letid\/\">LeTID.<\/a>\u00a0 LeTID is made worse by hot and humid conditions. Fortunately, PERC panels can be made resistant to this effect and such solar panels are included among the Top Performers for this test.<\/p>\n<p>One interesting thing to note about this year&#8217;s

spends a page or two gushing about how far solar has come and some of this gush is probably worth repeating:<\/p>\n<blockquote><p>&#8220;Since PV Evolution Labs (PVEL) was established in 2010&#8230; total installed photovoltaic (PV) capacity expanded tenfold to over 400 GW.&#8221;<\/p>\n<p>&nbsp;<\/p>\n<p>&#8220;Total solar capacity is expected to reach 1 TW<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/solar-panel-scorecard-2019\/#en-30859-3' id='enref-30859-3' onclick='return hhEndnotes_show(30859)'>3<\/a><\/sup> by 2023&#8243;<\/p>\n<p>&nbsp;<\/p>\n<p>&#8220;In only 10 years, the average price of PV modules dropped by 90%&#8221;<\/p><\/blockquote>\n<p>But in other quotes PVEL cautions that:<\/p>\n<blockquote><p>&#8220;75% of the world&#8217;s installed solar PV capacity has operated for less than 5 years.&#8221;<\/p>\n<p>&nbsp;<\/p>\n<p>&#8220;Long-term field data that proves today&#8217;s PV modules will perform reliably for decades does not exist.&#8221;<\/p>\n<p>&nbsp;<\/p>\n<p>&#8220;Certifications and warranties cannot fully protect PV module buyers from field failures and subsequent financial consequences.&#8221;<\/p><\/blockquote>\n<p>They sure make it sound like we should pay attention to PVEL and their reports.<\/p>\n<h2>The Scorecard Routine<\/h2>\n<p>PVEL follows DVNGL&#8217;s usual method of presenting scorecard results.\u00a0 This consists of not telling us:<\/p>\n<ul>\n<li>Which panels performed poorly, or even&#8230;<\/li>\n<li>If a solar panel was tested at all.<\/li>\n<\/ul>\n<p>They only tell us which solar panels did well on a test by suffering less than 2% reduction in performance.\u00a0 These are designated their Top Performers.\u00a0 We don&#8217;t even know which are the best out of this group as they are simply given in alphabetical order.<\/p>\n<p>If you want detailed information you can pay PVEL for a detailed report, but I presume you&#8217;ll have to promise not to blab about the results all over the internet.<\/p>\n<h2>The Four PVEL Tests<\/h2>\n<p>PVEL subjected solar panels to 4 tests:<\/p>\n<ul>\n<li>Thermal Cycling:\u00a0 Determines the effects of temperature change.<\/li>\n<li>Damp Heat:\u00a0 How well a solar panel handles hot and humid environments.<\/li>\n<li>Dynamic Mechanical Load Sequence:\u00a0 How well they handle flexing from wind or snow.<\/li>\n<li>Potential Induced Degradation:\u00a0 How well they resist deterioration from stray currents.<\/li>\n<\/ul>\n<p>Manufacturers have to pay for these tests and decide which types of panels they produce undergo which tests.\u00a0 What they can&#8217;t do is decide which specific panels get tested.\u00a0 PVEL is very careful to ensure only solar panels made for normal use are selected to prevent companies handing over high quality ring-ins.<\/p>\n<h2>Thermal Cycling Testing<\/h2>\n<p>Stuff expands when heated and contracts when cooled.\u00a0 Because this happens at different rates to different materials it puts stress and strain on joins and connections and can damage and break them.\u00a0 To test resistance to this, PVEL shoves panels into a combination freezer\/oven, cools them down to -45 degrees, and then heats them up to 40 degrees.\u00a0 This is done 400 times over a month and a half.<\/p>\n<p>It&#8217;s important for solar panels to do well on this test no matter where they are installed.\u00a0 But it is especially important for inland Australia where the temperature differential between day and night can be extreme.<\/p>\n<p>Top Performers &#8212; those that suffered less than a 2% decline in output &#8212; are shown in this chart:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-31151 size-full\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2019\/06\/thermal.jpg\" alt=\"Solar panel top

and &#8212; in the case of the cheapest and shoddiest panels &#8212; can cause them to fall apart.<\/p>\n<p>Provided you stay away from crappy solar panels you are not likely to get one that goes to pieces.\u00a0 But in PERC solar panels heat and humidity can cause a type of deterioration in called LeTID, which you can <a href=\"https:\/\/www.solarquotes.com.au\/blog\/perc-solar-panels-letid\/\">read about here<\/a>.\u00a0\u00a0 Because of this and because PERC panels are now so common, it has caused the average result on this test to go backwards instead of following the general trend of improving quality.<\/p>\n<p>The good news is there are PERC panels that are resistant to this and some are included among the Top Performers:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-31175 size-full\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2019\/06\/damp-heat.jpg\" alt=\"Solar

to see in Australia are the Indian made Adani\/Mundra and Vikram panels.<\/p>\n<h2>Dynamic Mechanical Load Sequence Testing<\/h2>\n<p>Constant flexing isn&#8217;t good for you, which you&#8217;ll know if you spend an afternoon gardening.\u00a0 Continual flexing by wind isn&#8217;t good for solar panels and the Dynamic Mechanical Load Sequence tests how well they resist damage from this.<\/p>\n<p>A good result on this test is a useful trait for a panel to have anywhere in Australia, but is obviously more useful in windy locations such as Newcastle and Toowoomba and less important in a place such as Adelaide, where the average wind speed is surprising low considering almost half the state&#8217;s electricity generation is from wind.<\/p>\n<p>Top Performers that suffered less than 2% deterioration in performance were:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-31178 size-full\"

257w\" sizes=\"(max-width: 562px) 100vw, 562px\" \/><\/p>\n<p>With Adani\/Mundra and Vikram Solar listed above, Indian manufacturers have done well in this category.\u00a0 But any of these Top Performers would probably be a good choice if you are planning to use a solar panel as a wobble board.<\/p>\n<h2>Potential Induced Degradation Testing<\/h2>\n<p>Potential Induced Degradation, or PID for short, is caused by electrical currents going where they shouldn&#8217;t.\u00a0 In poorly made panels it can cause a rapid deterioration and eventually cause the entire solar panel to fail.\u00a0 It&#8217;s made worse by hot and humid environments making resistance to it is especially important in tropical Australia.\u00a0 Higher voltages also exacerbate it.\u00a0 Large commercial solar can have voltages higher than the residential limit of 600 volts, so PID resistance is an especially important consideration.<\/p>\n<p>Fortunately, makers of quality solar panels have worked hard to eliminate or at least minimize this problem, so this test category has the most Top Performers and the average result is considerably better than in previous years:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-31185 size-full\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2019\/06\/pid-test.jpg\" alt=\"Solar panel top performers - potential induced

sizes=\"(max-width: 556px) 100vw, 556px\" \/><\/p>\n<h2>Manufacturer Comparison<\/h2>\n<p>A Top Performer result is clear evidence a solar panel can handle a particular test with minimal deterioration.\u00a0 But because we don&#8217;t know if a panel was given a particular test or not, if it&#8217;s not listed as a Top Performer it doesn&#8217;t mean we can conclude it can&#8217;t meet that standard.\u00a0 This means we can&#8217;t conclude that any particular panel isn&#8217;t good.\u00a0 But just knowing which panels are definitely good is still useful.<\/p>\n<p>If I take the 15 panel manufacturers that had a solar panel receive one or more Top Performer results I can separate them into 4 categories.\u00a0 These range from those that received a Top Performer result for a panel in every test to those that only received it for one test:<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-31228 size-full\"

but it is a good sign because it shows they at least know how to make durable solar panels that can pass those tests.<\/p>\n<p>But don&#8217;t get too carried away by this table.\u00a0 For all we know <a href=\"https:\/\/www.solarquotes.com.au\/blog\/znshine-solar-panels\/\">ZNShine<\/a> with its single Top Performer result only paid for one test and if their panels had received every test they would have got a Top Performer result for each.\u00a0 Also, there would be producers of high quality solar panels that didn&#8217;t bother to have any tested.\u00a0 This could be because they have their panels independently tested elsewhere, because they didn&#8217;t think the expense was worth it, or simply because they couldn&#8217;t afford to have their panels tested because they are going broke.\u00a0 The solar panel industry is extremely competitive, even for high quality manufacturers with excellent reputations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new Module
