The PV planner from the Cologne-based Hottgenroth Group helps with the design and optimization of photovoltaic systems: the software simplifies planning on a 3D building model and calculates electricity yield and cost-effectiveness.
Without extensive CAD knowledge, it is possible to capture structures of existing buildings or, for example, create and display new roof shapes. New electrotechnical functions supplement the PV project planning. Shading calculations for the building and climate data are included. How the system will later look on the roof can be visualized in the 3D model and clearly presented to customers.
An extensive and manufacturer-flexible product database also allows you to make your own entries and enables a large number of connection combinations. For each selected combination of module and inverter, the PV planner determines the connection options and shows the variants in a comparison. Battery storage can be taken into account as an option. The display of the state of charge for each day allows conclusions to be drawn on the selection of the correct size of storage. The profitability of a planned system is determined with the integrated profitability calculation. In addition, the yield values required by KfW in accordance with DIN 18599-9 are output, which are relevant for the crediting of electricity from PV systems.
