Real Life Shadow Calculations - anyone?

[tilt]

Niiiice, thanks ... the angle of the roof will actually be close to the same, as I want to raise the walls as well, but that shouldn't really make much difference since the top will be at the same height.
My town wasn't on the list, but I picked one half an hour (30 km) north from here.

Optimum Tilt of Solar Panels by Month

Figures shown in degrees from vertical

Jan	Feb	Mar	Apr	May	Jun
18°	26°	34°	42°	50°	58°
Jul	Aug	Sep	Oct	Nov	Dec
50°	42°	34°	26°	18°	10°

So I'm guessing these numbers of the tilt of the solar panel corresponds to the angle of the sun (ie the same angle)?
Also, the angle is when the sun is at its highest, right?
So now I "just" have to learn how to make/move the sun in sketchup (and measure angles in there)

I *think* you're right about the angles. You don't need the angles in Sketchup though. There's a slider for month and a slider for the time of day in the Shadows Settings (Window -> Shadow). Just set these to the required setting and use the Tape Measure Tool (T, or Tools -> Tape Measure) to measure where the shadow ends. Or just guess it a bit, there are enough reference points on your drawing.



You can actually put a picture from Google Maps under the house, but I obviously do not know your address, and Trelleborg was too large to search for a house with these precise specifications
