L&rsquo;Office f&eacute;d&eacute;ral de l&rsquo;&eacute;nergie recommande ce logiciel dans le cadre du d&eacute;veloppement des installations solaires alpines, explique la ZHAW dans un <a href=\"https:\/\/www.zhaw.ch\/de\/lsfm\/ueber-uns\/aktuell-medien\/medienmitteilungen\/detailansicht\/event-news\/alpine-photovoltaik-simulationen-unterschaetzen-die-stromertraege\/\" target=\"_blank\" rel=\"noopener\">communiqu&eacute;<\/a> correspondant. Les r&eacute;sultats des recherches montrent &laquo;&nbsp;que la proc&eacute;dure propos&eacute;e par la Conf&eacute;d&eacute;ration est judicieuse et que les rendements sont plut&ocirc;t sous-estim&eacute;s&nbsp;&raquo;, pr&eacute;cise le communiqu&eacute;.<\/p>\n<p class=\"bodytext\">Pour la validation, les chercheurs de la ZHAW ont effectu&eacute; un grand nombre de mesures sur le Totalp &agrave; Davos GR au cours du semestre d&rsquo;hiver 2023\/24 avec une installation miniature flexible &agrave; plusieurs rang&eacute;es. Les donn&eacute;es de mesure correspondaient en grande partie aux donn&eacute;es collect&eacute;es simultan&eacute;ment dans l&rsquo;installation exp&eacute;rimentale existante sur le m&ecirc;me site. En revanche, les rendements calcul&eacute;s &agrave; l&rsquo;aide de la simulation de PVSyst ont toujours eu tendance &agrave; &ecirc;tre inf&eacute;rieurs.<\/p>\n<p class=\"bodytext\">Les chercheurs expliquent cela par les valeurs d&rsquo;alb&eacute;do de <a href=\"https:\/\/meteonorm.com\/\" target=\"_blank\" rel=\"noopener\">Meteonorm<\/a> utilis&eacute;es par le logiciel. L&rsquo;alb&eacute;do est une valeur indiquant la proportion de lumi&egrave;re solaire r&eacute;fl&eacute;chie par le sous-sol. Parall&egrave;lement, les chercheurs ont pu montrer qu&rsquo;un rayonnement arri&egrave;re sur un panneau solaire biface augmente le rendement d&rsquo;environ 25 &agrave; 35 pour cent.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Des chercheurs de la ZHAW ont v\u00e9rifi\u00e9 la pr\u00e9cision du logiciel PVSyst pour estimer le rendement des installations solaires alpines.
