Failure in financial calculation

Anders Lundberg

Recommended Posts

As a double check I run my own Excel calculation and when comparing that to the PV Sol calculation I find a difference which I hope you can explain.

Please look at the attached file; Financial Analysis; First year saving. SEK 5.233,68 

Then look at the cash flow Table year 1; Electricity saving. SEK 5.131,06

Should´t these two figures be the same? I have 0 in all inflation rates to eliminate that as an explanation.

Next Total Payment from Utility in First year is SEK 6.037,03

I would expect that to be equivalent to Feed-in / Export Tariff in the Cashflow table or ?

Hi Anders,
if you also set the value "Annual Avarage return on capital employed" in the Financial Analysis Parameters dialog to zero, the figures for Electricity saving are the same every year.

Even then, the value for "Feed-in / Export Tariff" is still lower than in the second year. This is due to the fact that the start of operation date of the plant is April 30. The "Feed-in / Export Tariff" is calculated monthly, but hardly anything is fed in in April. If the start of operation date of the plant is 1 May, the figures for the first and second year are identical.

Best Regards
