Abstract

Un module photovoltaïque génère de l'énergie électrique lorsqu'il est installé sur un toit. Le module est construit sous la forme d'un sandwich stratifié comportant une couche supérieure protectrice transparente collée à une couche photovoltaïque. La couche photovoltaïque est collée à la partie supérieure d'une couche rigide, de préférence constituée d'une matière plastique renforcée de fibres. Un joint d'étanchéité à bord conique est disposé autour du bord extérieur périphérique du module, de sorte que l'eau et les débris s'écoulent facilement. Le joint d'étanchéité à bord conique est de préférence disposé adjacent à la couche photovoltaïque, et au-dessus de la couche de substrat rigide. Le joint d'étanchéité à bord conique est plus mince au niveau de sa partie périphérique extérieure qu'au niveau de sa partie adjacente à la couche photovoltaïque. Le module stratifié comporte de préférence une couche de ruban collant double face sur la partie inférieure destinée à amener le module à adhérer à la surface d'un toit.
