Support structure of solar substructure used for assembling solar module installed in e.g. roof of building, has support portion whose height at front end of side leg is less than height at rear end of side leg

摘要

The support structure (30) has a side leg (350) that is arranged opposite to a side leg (330). The distance between the side legs is increased from an upper end (32) to a lower end (34) of the side leg (330). The height of the support portion at a front end (36) of the side leg (330) is less than the height of the support portion at a rear end (38) of side leg (330). The holes (302,306) are formed at the surfaces of the two side legs.
