The performance tab allows for the plotting of various KPIs associated with the asset performance. These KPIs can be plotted in bar, line, or scatter format daily or monthly. Another attribute of this tab is the ability to overlay multiple plots by adding multiple KPIs on the same axis or plot them on a secondary axis to allow for appropriate scaling.
Users can choose to plot data sets as a bar, line, or scatter depending on the their preference or visualization desired.
Users can select from numerous solar performance metrics and measurements to create graphical comparisons. These metrics are listed below.
Solar Performance Categories
Reported Production : Reported Device Production in MWh. Calculated as SUM(Active Power 10min kW)/6000 to get the value in MWh.
Reported Capacity Factor : Reported Capacity Factor (Reported Production / Production Capacity) Percentage
Horizontal Irradiation : Irradiation measured on a horizontal plane at the site during the reporting period
Incident Irradiation : Irradiation measured as seen from the plane of the array at the site during the reporting period
Time Based Availability :Percentage of Time when Devices were Available for Operations. This is calculated by taking excluding the Alarms marked with Available = FALSE (Unavailable) on Alarms module. Thus, if out of a 10 minute reporting period there was an unavailable alarm for 2 minutes then we will mark the TBA for that 10minute duration as 80%. The overall TBA number is an aggregation of TBA values at each 10 minute interval.
Energy Based Availability :Contractual Energy Based Availability Percentag based on the equation below :
Production based EBA (Contractual) =
(Reported Production)/(Reported Production + Energy Loss)
Actual PR : Performance Ratio adjusted by actual irradiance compared to STC irradiance
Weather Corrected PR : Performance Ratio adjusted by actual irradiance compared to STC irradiance and actual temperature compared to STC temperature
Actual PR(Filtered) : Performance Ratio adjusted by actual irradiance compared to STC irradiance with downtimes and lost production periods filtered out
Weather Corrected PR(Filtered) : Performance Ratio adjusted by actual irradiance compared to STC irradiance and actual temperature compared to STC temperature with downtimes and lost production periods filtered out
