Title
(EN) SOLAR TRACKING DURING PERSISTENT CLOUDY CONDITIONS
(FR) SUIVI SOLAIRE PENDANT DES CONDITIONS NUAGEUSES PERSISTANTES
Abstract
(EN)
A method may include obtaining current data from a sensor related to performance of a solar power generating device, and comparing the current data from the sensor to previously stored data to detect a decrease in expected power generation. The method may also include determining whether the decrease in expected power generation is designated a persistently occurring decrease, and, based on the designation of the decrease as being persistent, changing an orientation of the solar power generating device to a stowed orientation.
(FR)
Un procédé peut consister à obtenir des données de courant à partir d'un capteur associé aux performances d'un dispositif de génération d'énergie solaire, et à comparer les données actuelles du capteur aux données précédemment stockées pour détecter une diminution de la production d'énergie attendue. Le procédé peut également consister à déterminer si la diminution de la production d'énergie attendue est désignée comme étant ou non une diminution se produisant de manière persistante, et, sur la base de du fait que la diminution est désignée comme étant persistante, à changer une orientation du dispositif de production d'énergie solaire dans une orientation rangée.
