La puissance d’un panneau photovolta\u00efque s’exprime en watt cr\u00eate Wc (ou watt peak Wp en anglais). Mais qu’est-ce que c’est exactement qu’un watt cr\u00eate ? En voici la d\u00e9finition pr\u00e9cise.<\/p>\n\n\n\n
La \u00ab\u00a0puissance-cr\u00eate\u00a0\u00bb, exprim\u00e9e en Wc, est une donn\u00e9e normative utilis\u00e9e pour caract\u00e9riser les cellules et modules photovolta\u00efques, mesur\u00e9e lors d’un test effectu\u00e9 en laboratoire, sous une irradiation de 1000 W\/m2<\/sup> et \u00e0 une temp\u00e9rature de 25\u00b0C, la lumi\u00e8re ayant le spectre attendu apr\u00e8s la travers\u00e9e de 1,5 fois l\u2019\u00e9paisseur de l\u2019atmosph\u00e8re (Air Mass 1.5)<\/strong><\/p><\/blockquote>\n\n\n\n
Cette norme est mondiale et tous les fabricants l’utilisent.<\/p>\n\n\n\n
Chez les fabricants de panneaux solaires, en sortie de cha\u00eene de production, chaque panneau passe dans une machine d\u00e9nomm\u00e9e \u00ab\u00a0flasheuse\u00a0\u00bb qui mesure le panneau. Cette \u00ab\u00a0flasheuse\u00a0\u00bb reconstitue exactement les conditions normatives \u00e9nonc\u00e9es ci-dessus et permet ainsi de mesurer le panneau sous 1000 W\/m\u00b2, \u00e0 25\u00b0C et avec le spectre AM 1,5. Une \u00e9tiquette est appos\u00e9e \u00e0 l’arri\u00e8re du panneau qui indique les r\u00e9sultats obtenus.<\/p>\n","protected":false},"excerpt":{"rendered":"
