[TRNSYS-users] open circuit voltage photovoltaitic panel

[javier mota]

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
