The resulting shade reduces the irradiation to the collector surface area.
Entry of the shade parameters in the programme is in two stages. You are able to define
the horizon and middle-distance objects.
Middle-distance objects fully shade the PV generator at certain times of the day.
In order to edit the horizon or objects which are relevant for the shading of your collectors,
you must have made a note of the prominent points of the horizon line from your solar
system. This can be done with a compass and protractor, with a sun path indicator, or with
a digital camera and editing software.
10.2.1 Shading: Horizon
A horizon point consists of the azimuth, i.e. the angle has measured from the horizontal
and the respective height angle, also measured in angle degrees.
-> For definition of the azimuth refer to: Orientation
-> Define a new horizon
a) by drawing with the mouse:
1. Start by clicking on the horizon line with the left mouse button. The current position of the
cursor can be seen in the upper bar, given as Azimuth : Height.
A dashed line is drawn between the starting point and the current position.
2. Click the next point using the left mouse button, thus confirming the dashed line.
The horizon line can only go from left to right. As a result, no dashed line can be seen if you
move the cursor left of the (current) end point.
3. Stop drawing by clicking the right mouse button.
4. Redrawing lines can only be done after completing the current sketch point and from an
already defined point. The following text is displayed in the upper bar:
To amend the horizon, click with the left mouse
button exactly on the horizon line.
It can be difficult to click on the existing horizon line where this is vertical. Rather
enter a fitting individual object.
5. You can delete the horizon at any time by clicking the New Sketch button.
6. Save this horizon and it's objects for further use in other projects.
