the distance between the upper surface of the forklift When the PV modules are stacked, they must be neatly tines and the ground should be less than 80mm, and stably stacked on a horizontal surface, and stacked otherwise collisions may easily occur, which may with the glass side facing down and the back side damage PV modules. facing up. At the same time, there must be cardboard bedding under the PV modules. For example, when 4.
modules: -40 °C to 85°C. Mechanical load on PV modules: under standard installation conditions, the maximum tested snow/wind load is 5400 Pa/2400 Pa and the design load (considering a safety factor of 1.5 times) is 3600 Pa/1600 Pa. Refer to 5.3 for detailed Fig. 1 Schematic diagram of tilt angle installation and mechanical loads. PV modules are strictly forbidden to be installed For and used in environments with excessive amounts preferably face south.
The PV module must be securely fastened to the mounting system. If the PV module is mounted in a snowy area, the height of the mounting system should be designed in a way that the lowest end of the PV module is not covered by snow. In addition, it should be ensured that the lowest end of the PV module is not shaded by surrounding trees or other Fig 3. Bolt installation for 60cell vegetation.

The 9x14mm mounting holes match with M8 bolts, while the 7x10mm mounting holes match with M6 bolts. 7x10mm mounting Fig. 9 Rails overlapping the short-side frame holes are positioned with a hole pitch of 400mm. ③ Make sure to use two stainless steel washers for each bolt, one on each side of the rack.
the glass and should not deform the frame, otherwise they may cause module damage. ② Be sure to avoid shadowing effects from the module clamps. Weep holes on the module frame must not be closed or obscured by the clamps. The clamp must have at least 8mm but no more than 11mm overlap with the frame of the module (The Fig. 11 Schematic cross section of the fringe clamp clamp section can be changed under the premise of ensuring reliable installation).
