Hello, I am running some simulations with the Parabolic Trough model and I would like to know:
(1) the formula for the IAM in the Parabolic Trough (Physical) model and
(2) how the efficiency of the collector is calculated (loss method?)
Doc Page:
nrel-pysam.readthedocs.io/en/latest/modules/TroughPhysical.html
Variable: IAM_matrix
Description: IAM coefficients, matrix for 4 collectors
Default Values SAM GUI: 1, 0.0327, -0.1351
Many thanks!
