Description

-Outside of CEC database, module models in SAM have default efficiencies out of date with current standards. Changes made are as follows:

-Simple Efficiency: Change efficiency to 19% for all irradiance bins (was 13.5%)
-CEC User Entered: Changed module surface to 1.0 m2 (was 1.3) to reach module efficiency of 18% (alternative: use module parameters from default CEC database module and make those new defaults)
-Sandia: Changed module library selection to SPR 305 WHT (efficiency 18.71%)
-IEC 61853: Use performance matrix from PVPMC Blind Modeling Comparisons for Panasonic 325 module (see attached reports and link)

The changes for Simple Efficiency, Sandia, and IEC 61853 look good. I would prefer to copy the default module parameters, since that's both more consistent and leads to a larger module size, which seems to be the industry trend.

Updated to CEC Database module specs
