After simulation, an economic evaluation of the system may be performed on the basis of the defined parameters and the simulation results. The economic tool is accessible in the "Project" dialog. It allows to define the initial installation costs and the yearly operating costs in order to calculate the cost of produced energy LCOE (Levelized Cost Of Energy). The tool may estimate a long term profitability based on initial costs, yearly charges, financial parameters and tariffs. It provides detailed financial results such as ROI (Return On Investment), payback period and NPV (Net Present Value).
