Solar elements can be placed in or on roofs using the appropriate button , or directly via drag and drop from the catalog of construction elements.
Solar elements behave in a similar way to windows, but in addition also have options in the properties dialog for roof-mounting or roof integrated mounting. For roof integrated mounting the solar elements create openings in the roofing, but not in the roof paneling
Note: Using normal input, solar elements can only be placed on roof planes. However, if the ‘Ctrl’ key is kept pressed on drag and drop from the catalog, the elements are treated as normal 3D objects and can be used anywhere.
