Abstract: A support for solar tracker photovoltaic modules, is provided with the modules (1) limited by a frame (2) intended to support a photovoltaic panel and the tracker is equipped with a rotation shaft (3), the support includes: a front portion (4), in turn comprising a hollow portion (6) which defines an inner chamber (7), wherein said hollow portion (6) includes two lateral surfaces (8), an upper surface (9) between the lateral surfaces (8) and a lower surface (10), a tab (11) that protrudes perpendicularly to the upper surface (9), the tab (11) and the upper surface (9). At least two holes (13) located on the two lateral surfaces (8) of the hollow portion (6), a rear portion (14) in turn include a housing (15) for the rotation shaft (3) to the rear portion (14), and a connecting portion (16).
