Abstract

L'invention porte sur un support de groupement de modules de cellules solaires (1), lequel support comprend un support en béton (10), un raccord (20) et une broche de montage (30). L'agencement vertical également espacé du support en béton forme une structure de groupement. Des supports en béton adjacents sont fixés et reliés les uns aux autres par l'intermédiaire du raccord (20). Les supports en béton à la périphérie de la structure de groupement produisent un encerclement de façon à former un polygone. Les supports en béton sont divisés en un premier support en béton (11) et un second support en béton (12). Le premier support en béton est à l'intersection du polygone. La broche de montage (30) est fixée et fait saillie au niveau du premier support en béton correspondant. Un trou d'installation (11c) du premier support en béton est inséré dans la broche de montage saillante et fixé. Le support en béton réduit considérablement les coûts de fabrication de supports. Le premier support en béton est fixé à l'intersection de la structure de groupement à l'aide de la broche de montage, et des supports en béton adjacents sont fixés et reliés entre eux par l'intermédiaire du raccord, ce qui renforce considérablement la stabilité du support de groupement. L'invention porte également sur un groupement de modules de cellules solaires et sur un système de génération d'énergie à cellules solaires.
