[esp-r] Re: Time:var graph for solar at ext face surf

[Jon Hand]

A question about direct and diffuse solar radiation...

One way of looking at the relationship between direct and diffuse is to use the
res time-step listing facility - focus on the direct and diffuse solar in the weather
data, list it via the time step reports with comma or tab separators and then
import the data into a spreadsheet as a scatter plot.

Subject: [esp-r]  Time:var graph for solar at ext face surf

Hello,
I am looking for a solution to show a time-variable graph for the
diffuse and direct radiation on an external wall.
I got a very simple model. It is just a box without any windows, with
just an inclined roof and some shading bodies.
Is there a way to get an time-(direct solar radiation on the outside of
the roof) graph? I just can find in the var.vsvar menu "solar at ext
face" but nothing in the time-var menue.
At the end, this should be the import for a pv model. So I need to know
how much radiation is available on that roof.

Thanks for your help
Lars
