CarlSEL Posted August 10, 2023 Report Posted August 10, 2023 Hi, So from the images below you can see that on the report I have a Spec. Annual Yield of 1116.18 kWh/kWp. (521,192/1116.8= 466.76kWp) Does this Spec Annual Yield take into account the performance ratio as 95.85%? So if the PR was 100% would the Spec Annual Yield would be close to 1164.5? But on the PV System Energy Balance I have different to figures as below: Best regards Carl Quote
developer_fw Posted August 16, 2023 Report Posted August 16, 2023 Hi CarlSEL Could you send me the .pvprj file via private message here in the forum? Thank you in advance and kind regards Frederik Quote
developer_fw Posted August 22, 2023 Report Posted August 22, 2023 Hello CarlSEL the project file which you did send to me is a different one than which the screenshots are from: The specific annual yield is calculated with PV energy (AC) minus standby use and the installed peak generator output power.

It is the other way around, you could say the performance ratio is determined by the real yield in comparison to the maximum possible yield and counts as a quality mark. Above 85% seems very high, though. I guess your module data could contain wrong values. Some manufacturers tend to enter very high values for IAM. Please double check that.
