EmmaVanoverschelde Posted August 9, 2021 Share Posted August 9, 2021 Hello everybodyAs 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 advanceEmma Link to comment Share on other sites More sharing options...

EmmaVanoverschelde Posted August 10, 2021 Author Share Posted August 10, 2021 Your feed-in tariff is too high, unrealistic price of energy. We got these values from Belpex, so It's quite accurate...

Belpex: https://my.elexys.be/MarketInformation/SpotBelpex.aspx 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. Link to comment Share on other sites More sharing options...
