Literature Review of Uncertainty of Analysis Methods (PV F-Chart Program), Report to the Texas Commission on Environmental Quality
MetadataShow full item record
This report reviews the reported uncertainty of the PV F-Chart analysis method by reviewing the published related accuracy of PV F-Chart analysis versus measured data, PV F-Chart predictions versus other methods, and PV F-Chart predictions versus TRNSYS simulations. This report begins with a review of the history of the PV F-Chart method, and includes an example PV F-Chart calculation. In summary, from the literature it was found that hourly PV F-Chart analysis versus measured data were shown to be within 4% of on-site measurement, PV F-Chart predictions versus TRNSYS simulations and another graphical method were also within 4% of annual values.
DescriptionThis literature review covers the PV F-Chart program, which is one of the legacy programs in the ESL’s Emissions Calculator (eCALC), a web-based emissions reductions calculator developed for the State of Texas. The eCALC program is a tool for those who want to see how their energy savings has reduced NOx emissions, a by-product made during the burning of fossil fuels. This report includes a brief history of the PV F-Chart method, its applications, accuracies, basic equations, and an example calculation.
