An electronic module compares the output voltage of a solar panel to an expected value and controls the power de-mand from the solar panel such that the output voltage does not vary from the expected value by more than a predetermined value. The predetermined value may be determined by correcting a room temperature value for the temperature dependence of the photodiodes comprising the solar panel and manufacturing tolerance.

L'invention porte sur un module électrique qui compare la tension de sortie d'un panneau solaire à une valeur attendue et qui commande la demande en énergie du panneau solaire de telle sorte que la tension de sortie ne varie pas par rapport à la valeur attendue de plus d'une valeur prédéterminée. La valeur prédéterminée peut être déterminée par correction d'une valeur de température ambiante pour prendre en compte la dépendance vis-à-vis de la température des photodiodes, comprenant le panneau solaire et la tolérance de fabrication.
