[BLDG-SIM] PV and WYEC files

[Griffith, Brent]

Smita,

A software package to consider here is EnergyPlus which now has a various ways of calculating photovoltaic power production using EnergyPlus weather data.  It isn't necessary to model an entire building, so developing input files isn't terribly difficult for PV-only modeling. EnergyPlus is free from www.energyplus.gov and the example file demonstrating PV systems is "GeneratorswithPV.idf"  There are three types of models available including a simple user-defined/constant efficiency, the equivalent one-diode model (originating from TRNSYS), and the newer, David King model from Sandia National Labs.   100+ input data sets are provided for the Sandia model.  The incident solar can be modeled to include the effects of other surfaces that might shade, or reflect onto, the panels.

Hi,

Where can I get detailed explaination of the fields of data in the WYEC files? Need the data to do some hand calcs for PV energy. Any other pointers and references regarding calculating PV performance will be helpful. Any software recommendations will be good too.

Thanks,

-Smita
