Abstract

La présente invention concerne une solution unique et inventive pour faciliter un système de tuiles photovoltaïques pour les applications de toiture photovoltaïque intégrée au bâtiment (BIPV). La présente invention offre une solution robuste et efficace à une entité ou une organisation en leur permettant de mettre en œuvre un système qui peut avoir au moins une seule pince à ressort latérale qui peut être configurée pour se verrouiller dans une semelle inférieure lorsqu'elle est poussée vers le bas. Le système peut ne nécessiter aucune fixation pour l'installation de la toiture photovoltaïque. La tuile photovoltaïque peut être déverrouillée ou désinstallée à l'aide d'un outil personnalisé, sans nécessiter d'accès visuel ou manuel pour la désinstallation, ce qui permet de l'enlever facilement pour la remplacer. En outre, les tuiles BIPV peuvent être superposées comme des ardoises conventionnelles ou des tuiles espagnoles, ce qui confère un aspect esthétique à la toiture.
