Generate tree shading

Generate tree shading tool is used to generate the shading based on custom shading angle. This tool helps to evaluate the shading and to avoid placing the frames in the shaded location. The shading area is automatically placed in the default restriction zone layer - PVcase Offsets.

Preparation for using the tool

The shading angle can be adjusted in the Layout generation settings window:

Note: the default N/S shading angle value is set to 22°.


The tree has to be a either a round shaped block object or a circle:

Important things to note are:
It's recommended to have tree object and height on separate layers;
• The software matches the height numbers to the nearest trees that it can find. For the trees that don't have a measurement near them PVcase will simply do an offset.

Using the tree shading tool

With topographic survey

  1. Click on the Generate tree shading tool.  Select the topographical height measurement and tree height measurement. 
  2. A prompt will come up asking whether the tree height is given from sea level (N - no, not a true height) or from the ground level at that point (Y - yes, true height).
  3. Finally select the tree block object.


Without topographic survey

  1. Click on the Generate tree shading tool. Select the tree height measurement. 
  2. Finally select the tree block object.

Important things to note are:

  1. When you select the tree height measurement PVcase will scan the site survey for tree height numbers on the same layer.
  2. You can manually create tree heights by copying custom tree height measurements on top of your DWG tree blocks but you have to place them on the same layer.

Generate SLA lines

The tool is used to check the placement of frames on 3D terrain. It is an indicator on what PVcase based the frame generation upon. If the generation calculation is correct - the pink lines should reach another frame row at some point.

After pressing Generate SLA lines button select if you want to draw up indicative placement lines for the entire PV area or for selected frames. Then you can easily use the tool to remove generated SLA lines.

Important thing to note: This tool does not represent the shading from the frames - rather it represents the so called 'shading limit lines'. These lines show the parts where the shading limit would intercept the next frame above it at the height of that frame.

Adapt to terrain

This tool is used to adapt a copied or moved frame from original location to another one. It allows the user for full customization of PV areas. 

ⓘ Adapt to terrain is used when your frames were generated using the topographic survey.

ⓘ Reassign frames is used when your frames were generated without using any topographic survey.

After moving or coping the frame - it will be colored in red. This will indicate the user, that he needs to adapt the frame in the new location. By clicking Adapt to terrain, you must:

  1. Select PV area;
  2. Select the entire row(s) with the newly added frame(s) for adaptation;
  3. Press Enter or Space.

Adapt to terrain - individual frame


Adapt to terrain - entire row


Adapt to terrain - multiple presets
