6.3 Test Loads and Design Loads
•
The Standard/lower loading capacity applies to normal
environment: the modules are tested under a maximum
positive pressure of 2400 Pa, and negative pressure of
1600 Pa, the modules are designed to meet a maximum
positive pressure of 1600Pa, and negative pressure of
1067 Pa, this design load was then tested with a safety
factor of 1.5 times.
•
The high loading capacity applies to severe environment,
like storm, big snow, etc. The modules are tested under a
maximum positive pressure of 5400 Pa, and negative
pressure of 2400 Pa, the modules are designed to meet a
maximum positive pressure of 3600 Pa, and negative
pressure of 1600 Pa, this design load was then tested with
a safety factor of 1.5 times.
•
For bifacial double-glass modules, it is recommended
that the beam is installed parallel to the long frame to
reduce backside shielding.
