Summary / Abstract: During the development of a photovoltaic plant project, the expected energy yield plays a key role for financial viability. Up to now, the uncertainty of the potential yield is dominated by the solar resource risk. The evaluation of solar resource for an average geographical situation still shows an uncertainty of approximately 5%. This risk can be significantly reduced by adaption to the specific site using qualified ground-based measurements. By measurements of highest quality and multiple years of overlap with satellite timeseries, the uncertainty of the solar resource may be reduced to a minimum of 2%. Such high accuracy of solar resource data sharpens forecasted project yields and improves financing terms. This study shows the impacts of on-site measurements to leveraged project finance and project value. Results show that costs for a one-year measurement campaign already pay off for plant sizes in the order of 10 MW. Moreover, the direct impact by high-quality on-site solar measurements translates into an increase of up to 200 kUSD each 10 MW.
