Re: [TRNSYS-users] thermal bridges effect

[Chaminda Ranaweera via TRNSYS-users <trnsys-users@lists.onebuilding.org>]

Hello;

Can anybody kindly tell me the meaning of “Array slope”, 
of Solar PV “Input” of “Type 94-a” Solar PV Panels. I 
change the “Array slope” parameter and see the output. 
But, I couldn’t see any significant variation of output of 
solar PV panels. It has not defined this paramer or sign 
convention for that on help manual

I am modeling an array f solar PV panels, I use “Collector 
Array Shading” for that. It also has “Collector Slope” as 
“Parameter”. Is that same as ““Array slope” parameter of 
“Type 94-a”, Solar PV panel.
The “Weather Data Reading and Processing” also has “Slope 
of surface” and “Azimuth of surface”. But it is also not 
defined the sign convention for above two parameters in 
“Help Manuals”.
How can we define above three parameters? Can anybody tell 
me?
According to my knowledge, the maximum solar PV gain shall 
be when it is oriented towards southern, when we stay in 
northern hemisphere. But I always gets the maximum solar 
pv output when Slope of Solar PV is “0” degrees, that 
means when it is horizontal.
Thank You,

Chaminda
