Abstract

La présente invention fournit une solution robuste et efficace à une entité ou à une organisation en leur permettant de mettre en oeuvre un système qui peut fournir des tuiles photovoltaïques améliorées avec un joint d'étanchéité contre les intempéries compressible intégré/intégré et des systèmes de montage pour des applications photovoltaïques intégrées au bâtiment (BIPV). Le joint d'étanchéité résistant aux intempéries compressible peut fournir une résistance élevée résistant même à des pluies entraînées par le vent, améliorer la fiabilité de l'équilibre de BIPV de systèmes, et protéger les composants de toit tels que la sous-couche et le tablier en contreplaqué. Les tuiles photovoltaïques ont un mécanisme de serrage et des découpes pour l'installation de la tuile photovoltaïque sur un mécanisme de verrouillage d'une semelle de base. La semelle de base est installée sur un pont de contreplaqué de toit résidentiel à l'aide de mécanismes d'auto-taraudage. L'installation de la tuile BIPV peut être réalisée sans retirer la tuile adjacente en insérant un outil et en pressant ainsi le composant de joint d'étanchéité contre les intempéries compressible sans accès manuel ni accès visuel.
