AI summary

When planning the installation of solar panels on a building facade, a decision must be made as to which solar panel models are suitable for the plan. The inventive method for selecting at least one solar panel model for an installation plan with multiple solar panels on a surface area is based on the properties of the surface area and the available solar panel models. This selection can take into account not only the dimensions of the solar panel models but also other relevant properties. The selection result enables optimized and simplified installation planning.
