This online service provides the solar financial model for the evaluation of the financial feasibility of a solar power project. Based on key technical and financial parameters, the model calculates IRR (internal rate of return), payback period, net cash flow, NPV, and provides many details on cash flow, balance, and other pages.

The form has fields with default values; you can use them or edit as needed. By clicking on Send button you will submit the form to our calculation server and in 10-30 seconds, you will see a .pdf file with calculations. Results of calculations for free are “noised” with some arbitrary coefficients. Therefore, if you send several times a form with the same values, you will have different results in .pdf files returned.

To get exact calculations by the solar financial model, please select “Yes, I need exact results”. This selection is available in the “Bill me” field. Shortly you will receive a bill of EUR 99. Upon receipt of the payment, we will send you by email another .pdf file with the exact results.
