Solar Model

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

Some data are entered in the form fields by default; you can use them or edit as needed. By click on Send button form will be submitted to our calculation server and in 10-30 seconds a .pdf file will be shown on this page (or downloaded by your browser). Results of calculations for free are “noised” with some arbitrary coefficients. If you send several times a form with the same values, you will have a number of different results in .pdf files returned.

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

We also have services for wind power and waste-to-energy projects financial calculations, as well as full-featured “what if” calculation scenarios. Please refer to our Financial Model page.
