What does the investment amount consist of?

The investment amount used for the calculation of the various values explained here is made up of the sum of the prices of all components used (PV & battery storage) that you compile per project, any state subsidies that are maintained by Eturnity AG (DE: none, CH: EIV, AUT: OeMag/KLIEN) as well as other additional subsidies that you can enter individually in the project in the Eturnity Solar Expert. If the marginal tax rate is set > 0 and the "Extended Economic Efficiency Calculation" is activated in the project settings, tax influences are also considered.
