Denne model muliggjorde ikke en egentlig kvantificering af, i hvilket omfang interessen for at investere i solcelleanlæg (f.eks. i form af investeringsafkast) ville dale i tilfælde af højere priser på celler og moduler.
This modelling did not allow for a proper quantification as to what extent the attractiveness of the investment in the PV installations (e.g. return on investment) could decline in the event of increased prices of the cells and modules.
