Abstract

L'invention concerne un panneau solaire combiné constitué d'un panneau solaire et d'un échangeur de chaleur. Le panneau solaire combiné selon l'invention présente sur la face arrière d'un panneau solaire (10) un échangeur de chaleur tubulaire grâce auquel le panneau solaire peut constamment fonctionner dans la gamme de températures optimale pour l'amélioration du rendement en courant. Sur le film de recouvrement de la face arrière du panneau solaire se trouvent une pluralité de tôles collectrices de chaleur (5) qui servent de collecteurs de chaleur et sont montées par collage. Sur les tôles collectrices de chaleur (5) se trouvent des plaques métalliques adhésives cannelées (6), elles-mêmes collées, dans la cannelure desquelles un tuyau métallique (2) est collé géométriquement de sorte que la transmission de force de l'échangeur de chaleur au panneau solaire est réduite au minimum. L'invention concerne également un procédé pour la production du panneau solaire combiné selon l'invention.
