Quels sont donc les facteurs qui influencent la production d'\u00e9lectricit\u00e9 des centrales photovolta\u00efques ?<\/p>\n<p>1.1. Quantit\u00e9 de rayonnement solaire<br \/>\nLes modules de cellules solaires sont des dispositifs qui convertissent l'\u00e9nergie solaire en \u00e9nergie \u00e9lectrique. L'intensit\u00e9 du rayonnement lumineux influe directement sur la quantit\u00e9 d'\u00e9nergie produite. Les donn\u00e9es relatives au rayonnement solaire dans diff\u00e9rentes r\u00e9gions peuvent \u00eatre obtenues sur le site web de la NASA consacr\u00e9 \u00e0 la recherche de donn\u00e9es m\u00e9t\u00e9orologiques, ou \u00e0 l'aide de logiciels de conception photovolta\u00efque tels que PV-SYS et RETScreen.<\/p>\n<p>1.2. Angle d'inclinaison des modules de cellules solaires<br \/>\nLes donn\u00e9es obtenues de la station m\u00e9t\u00e9orologique sont g\u00e9n\u00e9ralement la quantit\u00e9 de rayonnement solaire sur le plan horizontal, qui est convertie en quantit\u00e9 de rayonnement sur la surface inclin\u00e9e du champ photovolta\u00efque, de sorte que la production d'\u00e9lectricit\u00e9 du syst\u00e8me photovolta\u00efque peut \u00eatre calcul\u00e9e. L'angle d'inclinaison optimal est li\u00e9 \u00e0 la latitude de l'emplacement du projet. Les valeurs exp\u00e9rimentales approximatives sont les suivantes :<br \/>\nA. Latitude 0\u00b0~25\u00b0, angle d'inclinaison \u00e9gal \u00e0 la latitude<br \/>\nB. Latitude 26\u00b0~40\u00b0, inclinaison \u00e9gale \u00e0 la latitude plus 5\u00b0~10\u00b0.<br \/>\nC. Latitude 41\u00b0~55\u00b0, inclinaison \u00e9gale \u00e0 la latitude plus 10\u00b0~15\u00b0.<\/p>\n<p>1.3. Rendement de conversion des modules de cellules solaires<\/p>\n<p>1.4. Pertes du syst\u00e8me. Comme pour tous les produits, au cours du cycle de vie de 25 ans d'une centrale photovolta\u00efque, l'efficacit\u00e9 des composants et la performance des composants \u00e9lectriques diminueront progressivement, et la production d'\u00e9lectricit\u00e9 diminuera d'ann\u00e9e en ann\u00e9e. Outre ces facteurs naturels de vieillissement, il existe \u00e9galement des probl\u00e8mes de qualit\u00e9 des composants et des onduleurs, de disposition des circuits, de poussi\u00e8re, de pertes en s\u00e9rie et en parall\u00e8le, de pertes dans les c\u00e2bles et d'autres facteurs.<br \/>\nDans le mod\u00e8le financier d'une centrale photovolta\u00efque g\u00e9n\u00e9rale, la production d'\u00e9lectricit\u00e9 du syst\u00e8me diminuera d'environ 5% en trois ans, et la production d'\u00e9lectricit\u00e9 diminuera jusqu'\u00e0 80% apr\u00e8s 20 ans.<\/p>","protected":false},"excerpt":{"rendered":"<p>M\u00e9thode de calcul de la production d'\u00e9lectricit\u00e9 des centrales photovolta\u00efques : production annuelle th\u00e9orique d'\u00e9lectricit\u00e9 = moyenne annuelle du rayonnement solaire total * surface totale de la batterie * efficacit\u00e9 de la conversion photo\u00e9lectrique.
