Shadow analyzing


I whold like to analyze the shadow effect on an object (skylight).

I’m using PV module as a skylight and try to get the amount of hour it is in shadow.
Finaly I want to get the percentage of the shading hours related to the totaly light hours (monthly and Yearly).

I found the following tool in the 1001 Shadows:
“analyze the duration when the selected point is under shadow”
I thoght it will help me but I don’t know I to work with it.

Any help will be helpfull.


Also take a look at SunHours


Hi, I use “Shadow Analysis” by DeltaCodes for examining exteriors.
Perhaps it is worth checking out?
