System Derating Factors
Under normal conditions, a photovoltaic module may experience conditions that produce more current and/or more voltage
than reported at Standard Test Conditions. Accordingly, when determining component ratings, the values listed for open
circuit voltage should be multiplied by a calculated factor based on the low temperature open circuit voltage temperature
coefficient. Refer to First Solar Application Note PD-5-435 for additional information on the calculation of this voltage
multiplication factor. Values listed for current should be multiplied by 1.25. Refer to Section 690-8 of the National Electrical
Code for an additional multiplying factor of 125 percent (80 percent derating) which may be applicable in computation of
maximum circuit current for proper conductor sizing. Adjustments of those factors might be needed to respect site specific
climate conditions.
