La production est g\u00e9n\u00e9ralement inf\u00e9rieure \u00e0 celle d\u2019une journ\u00e9e claire comparable, mais elle n\u2019est pas n\u00e9cessairement nulle.<\/p>\n<h3>Faut-il retirer la neige ?<\/h3>\n<p>Ne montez pas sur une toiture pour cela. Laissez \u00e9voluer la situation et demandez l\u2019avis d\u2019un professionnel si un probl\u00e8me de s\u00e9curit\u00e9 ou un d\u00e9faut persistant est constat\u00e9.<\/p>\n<h3>Une inclinaison plus forte est-elle toujours meilleure en hiver ?<\/h3>\n<p>Elle peut favoriser la r\u00e9ception d\u2019un soleil bas dans certaines situations, mais le bon choix d\u00e9pend de l\u2019orientation, des contraintes du site et de l\u2019objectif annuel. Ne modifiez pas vous-m\u00eame une fixation ou une toiture.<\/p>\n<h3>Peut-on recharger une batterie solaire en hiver ?<\/h3>\n<p>Oui si la production disponible et le syst\u00e8me de charge le permettent. Le temps de recharge d\u00e9pend du surplus effectif, de la capacit\u00e9 de batterie, du rendement et des limites du mat\u00e9riel.<\/p>\n<h3>Peut-on \u00eatre autonome en \u00e9lectricit\u00e9 tout l\u2019hiver ?<\/h3>\n<p>Une autonomie totale ne peut pas \u00eatre promise \u00e0 partir de la seule puissance des panneaux et de la capacit\u00e9 d\u2019une batterie. Elle d\u00e9pend aussi des consommations, de la m\u00e9t\u00e9o, du dimensionnement et des \u00e9ventuelles sources d\u2019appoint.<\/p>\n<h3>Pourquoi mon application affiche-t-elle moins de kWh qu\u2019en \u00e9t\u00e9 ?<\/h3>\n<p>La dur\u00e9e du jour, les nuages, le soleil bas et les ombres expliquent souvent une baisse saisonni\u00e8re.
