Hello everybody
As you can see in the picture below, my NPV and ROI are really high, while my payback period is very low.
Does anybody knows how it is possible that these values are so high/low?
Thanks in advance
Emma

Your feed-in tariff is too high, unrealistic price of energy.

We got these values from Belpex, so It's quite accurate...

Those are prices per MWh. Check if you entered the correct price per kWh. Electricity doesn't cost that much, so the issue is with your feed-in tariff. A screenshot of that tab would help if there is further doubt.
For example, assuming the year 1 production is 13,346 kWh (the energy sold to the grid), your year 1 cost of energy according to your results is 344,300/13,346 = €25.79/kWh. This does not seem correct.
