Abstract

Le procédé traditionnel de fixation des modules de cellules solaires sur une structure nécessite du temps et pose des problèmes parce que les modules de cellules solaires sont fixés un à un avec des boulons après que la structure soit formée. Dans la présente invention, un module de cellules solaires est formé en disposant intégralement un membre structurel sur un panneau de cellules solaires où les éléments de cellules solaires sont disposés entre un substrat translucide et un matériau de surface arrière, caractérisé en ce que le membre structurel présente une structure intégralement jointive avec le membre structurel d'au moins un autre module de cellules solaires, si bien que, puisqu'un membre structurel servant de structure est assemblé intégralement avec un panneau de cellules solaires à l'avance, une matrice de cellules solaires peut être formée sur le lieu de travail en joignant les membres structurels des modules adjacents ensemble.
