The latest trend in the PV industry seems to be for bigger, heavier, and much more powerful modules. This raises a question: Where does this leave the rooftops segments where smaller size and weight distribution are already crucial for project designs? <\/p>\n\n\n\n

At present, the variety of wafer sizes in the PV industry leads to difficulty in module selection for customers. The 210mm is predicted to be the ultimate size for the PV industry in the next 5-10 years. <\/p>\n\n\n\n

Trina Solar<\/a> offers a solution by introducing the new Vertex S Series which follows some of the latest technology trends with the large 210mm wafer, cells cut into three pieces, with minimum gaps between the cells. These technologies are packed into a slightly smaller package weighting\u00a0just over 20kg and designed with existing rooftop racking systems in mind.\u00a0<\/p>\n\n\n\n

Contrary to the previous products, Vertex S Series is dedicated to the commercial and residential rooftop segment. It was designed with the following focus points in mind: <\/p>\n\n\n\n

    \n
  • Power efficiency<\/strong>\u00a0\u2013\u00a0the main driver for developing Vertex S\u00a0was the fact that a new generation product needs to be more powerful and more efficient.\u00a0<\/li>\n\n\n\n
  • Durability<\/strong>\u00a0\u2013\u00a0Vertex S includes an improved warranty. It has a thinner but stronger frame and higher mechanical load capability. The snow load value is 6,000Pa (as compared to the previous 5,400Pa),\u00a0and the wind load value is 4,000Pa.\u00a0<\/li>\n\n\n\n
  • Appearance<\/strong>\u00a0\u2013\u00a0a full black module has been included in this series for those who have a special dedication to the visual of the module and like the full black appearance on the roof. It was designed with aesthetics in mind;\u00a0an excellent cell color control was achieved by dedicated cell blackening treatment and machine selection. Thinner wires that appear all black at a distance have also been used.\u00a0<\/li>\n\n\n\n
  • Size<\/strong>\u00a0\u2013\u00a0rooftop segment is sensitive to the size and weight of modules. The handling of modules is also important.\u00a0<\/li>\n\n\n\n
  • Universal solution<\/strong>\u00a0\u2013\u00a0due to the diversity of roof types, diverse installation solutions need to be available. Vertex S is flexible for different system deployments, like 4 points short and long side mounting, shared rail and slide-in mounting, crossed beam mounting, etc.\u00a0<\/li>\n<\/ul>\n\n\n\n

        How to Implement Larger New Generation Modules on Rooftops? <\/h2>\n\n\n\n

        Layout and Designing Array <\/strong><\/p>\n\n\n\n

        \"\"
        Layout & Design<\/figcaption><\/figure>\n\n\n\n

        The size of Vertex S allows you to design the layout in a way that generates more power using fewer modules (when compared to the Trina Honey M 120c – 340Wp module). <\/p>\n\n\n\n

        Electrical Configuration <\/strong><\/p>\n\n\n\n

        \"\"
        Electrical configuration<\/figcaption><\/figure>\n\n\n\n

        The electrical configuration is fairly easy and beneficial. Let\u2019s take as an example a 100kVA inverter with outputs of 10 MPPT with 2 strings per MPPT. We can configure the inverter using the same voltage (34.2V) and the same number of modules per string. <\/p>\n\n\n\n

        With Trina 120c<\/strong>. \u2013 340Wp module (Honey M), we need 360 modules with 122 kW per inverter and 18 strings (20 modules per string). <\/p>\n\n\n\n

        With Trina 120c.<\/strong> \u2013 400Wp module (Vertex S), we need 300 modules with 120 kW per inverter and 15 strings (20 modules per string). <\/p>\n\n\n\n

        The result is fewer modules, fewer cables, and fewer connectors, which means shorter installation time and optimized cost. <\/p>\n\n\n\n

        Mounting Systems & Compatibility<\/h2>\n\n\n\n

        Some systems are already ready to accept the new generation modules, but some are not. In some systems, the width may not be permissible. It is important to check the mounting system specification with the supplier to make sure they are compatible. <\/p>\n\n\n\n

        This new generation of modules optimizes power, time, and cost while keeping reasonable dimensions and weight for rooftop work without introducing new big challenges for design and construction. <\/p>\n\n\n\n

        The sweet spot for this module is a large-scale rooftop. The dimensions and weight of this module are a good compromise between 72c and 60c mainstream modules. It may be less attractive for smaller or complex roofs. <\/p>\n\n\n\n

        Below are three examples of three mounting variants: <\/p>\n\n\n\n

        Conclusion <\/h2>\n\n\n\n

        Trina is one of the top solar panel manufacturers, in terms of volume, quality and reliable deliveries. The new Vertex S module comes with a fantastic warranty (15 years on product and 25 years on power). The degradation levels and temperature coefficients are outstanding. It\u2019s a great product that uses cutting-edge technology (M12 wafer with MBB). The weight is suitable for both commercial and residential installation. The size below 2m2<\/sup> is also within the acceptable brackets for residential installations. Due to the new design, the 30mm frame is strong and gives an added benefit as regards storage and transportation. It enables you to fit 36 pieces per box and 936 per standard 40\u2019\u2019 container, which gives a total of 380kW in each container. Vertex S can be installed on all kinds of commercial and residential roofs (tile, flat, trapezoidal) with landscape or portrait modules, using a single layer, double layer, or cross railed system with either clamping or insertion system. <\/p>\n\n\n\n

        Vertex S, with its maximum power of 400W and maximum efficiency of 21.1%+, surely proves to be small in size yet big on power. Its size and power allow you to better utilize the available space, to put more power on the same rooftop (compared to former generations of products), and to harvest more energy. It provides a universal solution for both residential and C&I rooftops together with high reliability and outstanding visual appearance. <\/p>","protected":false},"excerpt":{"rendered":"The latest trend in the PV industry seems to be for bigger, heavier, and much more powerful modules.…","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"csco_singular_sidebar":"","csco_page_header_type":"","csco_appearance_grid":"","csco_page_load_nextpost":"","csco_post_video_location":[],"csco_post_video_location_hash":"","csco_post_video_url":"","csco_post_video_bg_start_time":0,"csco_post_video_bg_end_time":0,"footnotes":""},"categories":[23],"tags":[229,307,244,247,358],"class_list":["post-214","post","type-post","status-publish","format-standard","category-solar-product-news-en","tag-210-mm-wafer-en","tag-solar-economy-en","tag-solarpanel-en","tag-trina-solar-en","tag-wafer-en","cs-entry","cs-video-wrap"],"_links":{"self":[{"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/posts\/214","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/comments?post=214"}],"version-history":[{"count":0,"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/posts\/214\/revisions"}],"wp:attachment":[{"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/media?parent=214"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/categories?post=214"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.solartraders.com\/en\/wp-json\/wp\/v2\/tags?post=214"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
