out-perform monofacials. \u00a0In 2019, 3% of all solar modules sold were bifacial, and this figure is predicted to climb to 10-15% this year, as we see more projects getting the greenlight globally.<\/p>\n<p>Here are some of our thoughts on bifacial technology and you can <a href=\"https:\/\/www.greentechmedia.com\/amp\/article\/bifacial-solar-is-the-new-normal-says-lightsource-bp\" target=\"_blank\" rel=\"noopener noreferrer\">also read GTM\u2019s recent interview with our Technical Director, Chris Buckland.<\/a><\/p>\n<h4><strong>More powerful from every angle <\/strong><\/h4>\n<p>The key strength of bifacial solar panels is in the name \u2013 by capturing sunlight on both faces of the panel, the efficiency of energy transfer is increased by around 14%, producing more energy from the same amount of space.<\/p>\n<p>In regions like Australia and the USA, where cost of labour is very expensive, this uplift in yield and increased efficiency has significant benefits to the internal rate of if return (IRR) \u00a0of projects, creating more financially viable opportunities for solar.<\/p>\n<h4><strong>Case Study: <\/strong><strong>Wellington Solar Farm, NSW, Australia\u00a0<\/strong><\/h4>\n<p>We are currently building one of the first (and largest) projects in Australia to deploy bifacial panels at scale. <a href=\"https:\/\/www.lightsourcebp.com\/au\/2019\/08\/lightsource-bp-begin-construction-first-australian-solar-project-2019\/\" rel=\"noopener noreferrer\">Wellington Solar Farm<\/a> is a 200MW utility scale solar plant located near Wellington, NSW, and when completed will feature:<\/p>\n<ul>\n<li><a href=\"https:\/\/www.lightsourcebp.com\/uk\/2020\/02\/canadian-solar-and-lightsource-bp-sign-1-2-gw-module-supply-agreement\/\" rel=\"noopener noreferrer\">500,714 Canadian Solar Bi-HiKu panels<\/a><\/li>\n<li>435,000MWh of clean, renewable electricity per year &#8211; enough to power 72,500 homes<\/li>\n<li>350,000 tonnes of CO<sub>2<\/sub> emissions displaced- equivalent to taking 121,580 cars off the roads.<\/li>\n<\/ul>\n<h4><\/h4>\n<h4><strong>Durable, with a longer lifetime<\/strong><\/h4>\n<p>According to a study by Wood Mackenzie Power &amp; Renewables, there\u2019s around 5.4GW of bifacial solar capacity operating globally, predominantly in Asia, with that number set to rise tenfold and achieve equal distribution across Asia and North America in the next five years.<\/p>\n<p>This popularity with developers is not just due to increases in efficiency, but also durability. Bifacial modules have glass on both sides, which increases the energy production but also extends the lifetime of the product when compared to its monofacial counterpart.<\/p>\n<h4><strong>Heavyweight champions<\/strong><\/h4>\n<p>These modules are also often up to 30% heavier than regular monofacial panels, as they\u2019re built to withstand significant weather conditions. The glass on a bifacial module can handle 2.5cm hail (typically the largest it will get), and many manufacturers use glass that\u2019s 2mm thick, as the flexibility reduces the number of micro-cracks, and allows the glass to bend, rather than break. As a result, bifacial modules can be used in a wide range of locations where solar would not have previously been considered a good option.<\/p>\n<p>The extra weight increases durability of the panels, cutting the frequency of part replacement, saving time and money. Due to this, the manufacturers guarantee includes a lower degradation rate (the decline in output that all solar panels experience over time) \u2013 another significant gain in IRR and project viability.<\/p>\n<h4><strong>But it\u2019s not without its challenges<\/strong><\/h4>\n<p>The panels do not stand alone, they fit within the framework of a project as a whole, and so many elements of site design have to be adjusted to fit.<\/p>\n<h4><strong>Investor assurance is key<\/strong><\/h4>\n<p>Another challenge is the bankability of the modules with financial institutions. To a point, bifacial technology is still \u2018new\u2019 and can be interpreted as a \u2018risky\u2019 investment. Early adopters, like ourselves are overcoming this hurdle by strengthening R&amp;D and demonstrating rigorous testing.<\/p>\n<p>As there are no international standards yet for bifacial panels, testing products consistently can be difficult. To overcome this, we\u2019ve been working closely with module providers on pre-shipment testing . We\u2019ve built healthy relationships with the top 10 global solar manufacturers, which has allowed us to place significant orders, currently earmarked for projects across Europe, the US and Australia.<\/p>\n<h4><strong>What\u2019s next?<\/strong><\/h4>\n<p>While bifacial panels are in many ways superior to monofacial panels, there is still potential to improve performance further. Without getting into deep technical specifics, the next step would be to upgrade the type of silicon wafer used in the cells of the panels, <a href=\"https:\/\/www.hahasmart.com\/blog\/2867\/whats-the-difference-between-n-type-and-p-type-solar-cells\" target=\"_blank\" rel=\"noopener noreferrer\">from traditional P-type to the more expensive but more efficient N-type<\/a>. We are currently trialling N-type cells on one of our projects in the UK and look forward to seeing the results.<\/p>\n<p>&nbsp;<\/p>\n\n        <\/span>\n      <\/div>\n    <\/div>\n  <\/div>\n\n
