Re: [TRNSYS-users] open circuit voltage photovoltaitic panel

["Diego A. Arias" <daarias@wisc.edu>]

Dear Javier,

I would recommend looking at the references cited in the mathematical 
description of Type 180 (Volume 5, section 5.2.9).  This component 
started as a model for a PhD thesis in the Norwegian University of 
Science and Technology. 
Best regards,

Diego
