Abstract

L'invention porte sur de multiples types de modules de cellules solaires (2A, 2B) ayant des longueurs horizontales différentes, lesquels modules sont disposés dans la direction horizontale (X) et dans la direction verticale (Y). Les parties de fixation spécifiées des éléments de bâti horizontaux des modules de cellules solaires (2A, 2B) sont fixées et supportées par des raccords de fixation (6). Dans des cas dans lesquels les parties de fixation spécifiées des éléments de bâti horizontaux de modules de cellules solaires (2A, 2B) qui sont voisines les unes des autres dans la direction verticale (Y) se font face, les parties de fixation spécifiées opposées des éléments de bâti horizontaux des modules de cellules solaires (2A, 2B) sont fixées et supportées par des raccords de fixation communs (6).
