INTRODUCTION
All photovoltaic (PV) modules must be installed in accordance with the manufacturer’s installation instructions. This technical bulletin summarises the installation instructions for the REC 250, Daqo 190 and Solar Frontier 150.
100 MM CLEARANCE TO ROOF
The modules should be located at least 100 mm above the roof surface
JUNCTION BOX AT HIGH END
The junction box should be located at the high end of the module, not the low end.
CLAMP ONLY ON LONG SIDES (EXCEPT REC)
The clamps should be fastened on the long sides, not on the short sides. REC is the only manufacturer which allows clamping on the short side
LOCATION OF CLAMPS (DISTANCE FROM END)
The following table shows the location of the clamp, as a distance from the end of the module:
The installation manual from Daqo does not provide exact limits for the location of clamps, so a ‘best practice’ location of 10-25% from the end is assumed.
MOUNTING TORQUE
The M8 cap screws should be installed with a tightening torque of approximately 12-14 N·m
