Support structure of photovoltaic devices is to be anchored on the drilling bases (8) advantageously in installing at unreinforced surfaces or to be anchored on the holders (12) in installing at reinforced surfaces. The structure consists of the rear leg (5), the front leg (9), the rear beam (4), the bottom beam (6), and the supporting beam (1). The internal angles in the triangle, consisting of the supporting beam (1), bottom beam (6) and the rear beam (4), equal 60° with the tolerance of ± 5°. The distance between the top part of the rear beam (4) and the central axis (O) is less than the distance between the bottom part of the rear beam (4) and the central axis (O). The bottom beam (6) is situated so that the connection of the front leg (9) with the bottom beam (6) is located higher than the connection of the bottom beam (6) with the rear leg (5). In an alternative solution, the rear beam (4) is situated vertically and the values of each internal angle in the triangle, consisting of the supporting beam (1), bottom beam (6), and the rear beam (4), are in the extent of 45° to 75°. The connection of the bottom beam (6) to the front leg (9) and/or the supporting beam (1) lies higher than the connection of the bottom beam (6) to the rear leg (5) and/or the rear beam (4). The triangle consisting of the bottom beam (6), supporting beam (1) and the rear beam (4) can also be formed so that the rear beam (4) is directed vertically and its connection to the bottom beam (6) is made at the angle of 90° ± 15°. |
