These parameters are the main electrical module
characteristics, available on any manufacturer data sheets. They
are usually given for
STC, but the program accepts measurements performed
under other conditions to establish the model from on-site
measurements in outdoor
conditions.
These parameters therefore include:
Gref and Tref: |
the reference irradiation and
module temperature conditions during reference measurements
(usually
STC). |
Isc and Voc: |
module short circuit current and
open circuit voltage at these given conditions. |
Impp and Vmpp: |
any operating point in the region of the maximum power
point at these given conditions. |
muIsc : |
temperature coefficient for Isc.
This has only weak influence on the module behaviour. When not
known, it can be taken as about 0.05%/°C. |
