2.2 BASE CASE
In order to create a Base Case PAN file the values for module area, short-circuit current (I
sc
), open-
circuit voltage (V
oc
), maximum power current (I
mpp
), maximum power voltage (V
mpp
), and
temperature coefficient of I
sc
and P
mpp
were taken from the module datasheet and input into PVsyst.
All other module parameters remained at the PVsyst default values. The inputs to PVsyst are
summarized in Table 2. The efficiency curves of the Base Case PAN files are shown in Figure 2
(PVsyst output) and are compared with the scaled measured curves in Figure 3.
