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

halo, I am javier mota from 3i-ingenieria, madrid
I am working with pv model 180 e
I have a book wich calculate Vocc(voltage open circuit ) as
Vocc=vocc, nominal+MUVOC*(Tcell-25)
Tcell=tambient+0.3*G, where G=radiation
I supose trnsys model is more accurate.
The problem is that Vocc with my book formule predict that for our
arrangement, series 25 panels,
woluld be on the limit of what may be admisible by the panles and
inverter.
But TRNSYS predict Vocc values no so critical, values are lower.
Must I think that the formule of my book is rude and so i mus be quiet
with tRNSYS prediction of Vocc
Can I found some internet direction with information about TRNSYS
model for PV.
Thanks in advance
