Defining restrictions
On this page, you can specify limitations for the roof. These can be dormers, skylights or similar objects that influence the installation of PV modules or also chimneys, trees or walls that might shade the roof. In addition, you can define distances that should be kept to the ridge, the roof edge and the eaves. Ask a roofer for their roof recommendations.
PV modules may be planned on the different dormers if needed. Restrictions such as skylights, round dormer windows or building blocks are regarded exclusively as interfering objects. No PV modules can be planned on them.
Prerequisites:
You must have opened a project and planned it up to the page Configure system (quick planning) or Configure PV system (detailed planning).
You must have opened the visual roof planning tool on the page Define restrictions.
Procedure:
- Select the type of obstacle (Dormers, Roof objects, Facade objects, Free-standing objects) and place it in the required position. Dormers, skylights, building blocks and cylinders can only be placed on the roof. Chimneys, trees and walls can be placed on the lot. If the surface is not large enough to insert the obstacle and in case of intersections with other objects, the obstacle appears red.
- In the case of dormers, skylights, building blocks and cylinders, enter the dimensions and the distances of the obstacles to the edges of the roof.
- To change the position and size of a dormer, click on the respective dormer with the mouse and adjust it. If several identical dormers are to be adjusted at once, the dormers can be selected one after the other by clicking on them and pressing the [Ctrl] key simultaneously. To make the entries easier, an input field will open on the right-hand side. Click on [Sace] to save your entries.
- In the case of chimneys, buildings and walls, enter the dimensions and the position of the obstacles.
- To use a defined obstacle multiple times, select the required obstacle and copy it by clicking the [Copy] button in the upper left corner.
- Move the mouse pointer over the place where the obstacle is to be inserted. If the obstacle can be inserted at the location, it will appear green. If the roof area is not large enough to insert the obstacle and in case of intersections with other objects, the obstacle appears red.
- To remove an obstacle, click on the respective obstacle and delete it. Click on either Del on the keyboard or on the [Delete] button in the upper left-hand corner.
- To continue the selection of PV modules, click on [Continue].
