This new operating voltage has a direct impact on the cost-effectiveness of the project, resulting in significant cost reductions, longer links and fewer junction boxes and wiring.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, all DC components also had to be upgraded to a higher operating voltage, and international regulatory bodies have issued new standards and certificates to ensure their suitability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this particular photovoltaic cable, the new standard, published in 2014, is <a href=\"https:\/\/standards.iteh.ai\/catalog\/standards\/clc\/00edeb15-bf19-4a72-8ed0-e7a26b25925c\/en-50618-2014\" target=\"_blank\" rel=\"noreferrer noopener\">EN 50618<\/a>. This standard specifies that cables in PV system installations must have a rated continuous voltage of up to 1.5 kV. The international safety qualification standard for PV modules &#8211; IEC 61730 &#8211; requires a photovoltaic cable to conform to EN 50618.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is important for specifiers to check whether the PV cable supplied by their suppliers conforms to the current standards, as these set higher requirements, e.g. for general low voltage cables.<\/p>\n\n\n\n<div style=\"height:33px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"planning-and-design-of-a-photovoltaic-plant-which-cables-are-included\"><\/span>PLANNING AND DESIGN OF A PHOTOVOLTAIC PLANT: WHICH CABLES ARE INCLUDED?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box-1024x626.jpg\" alt=\"\" class=\"wp-image-29323 lazyload\"\/><noscript><img decoding=\"async\" width=\"1024\" height=\"626\" src=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box-1024x626.jpg\" alt=\"\" class=\"wp-image-29323 lazyload\" srcset=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box-1024x626.jpg 1024w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box-300x184.jpg 300w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box-768x470.jpg 768w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-box.jpg 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/noscript><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><sub><sub>Photovoltaic plant with string box<\/sub><\/sub><\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter-1024x597.png\" alt=\"\" class=\"wp-image-29317 lazyload\" style=\"width:600px\"\/><noscript><img decoding=\"async\" width=\"1024\" height=\"597\" src=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter-1024x597.png\" alt=\"\" class=\"wp-image-29317 lazyload\" style=\"width:600px\" srcset=\"https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter-1024x597.png 1024w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter-300x175.png 300w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter-768x448.png 768w, https:\/\/www.topcable.com\/blog-electric-cable\/wp-content\/uploads\/2025\/04\/string-inverter.png 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/noscript><\/figure>\n\n\n\n<p class=\"has-text-align-center wp-block-paragraph\"><sub><sub>Photovoltaic plant with string inverter<\/sub><\/sub><\/p>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:8px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">A photovoltaic plant consists of panels, cables, junction boxes, electrical and electronic equipment. To understand how the installation works, we will divide it into parts and types of cables.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>String cables<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are the cables that run from the PV panel to the concentrator or Stringbox.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>String box<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is a junction box that includes devices to control and connect the PV modules.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is the transition point where the cables &#8211; 4 and 6 mm2 cross-section &#8211; connect to the DC feeder and switch to larger aluminium cables &#8211; 95 to 300 mm2 -.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>DC power cables<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are the cables &#8211; usually made of aluminium &#8211; that connect the stringboxes to the inverters.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Inverter<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A converter that transforms the DC power from the PV generator into alternating current (AC).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>AC power cables<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The cables &#8211; usually aluminium &#8211; that connect the inverters to the transformer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Transformer<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A device that transforms the low voltage current (1500V) into medium voltage (12 \/ 20kV).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Why all these processes? Because photovoltaic panels produce Direct Current (DC). The voltage that we have in our homes and that which travels through the electrical networks is Alternating Current (AC), so it has to be transformed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Medium voltage cables<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are the cables -usually made of aluminium- that connect the transformer to the public electricity network.
