The performance ratio featured a standard deviation of 11.7%, indicating significant variability in the performance of individual systems, with only one or two systems achieving model-estimated energy delivery. Some level of underperformance is expected, and 100% availability would be prohibitively expensive to pursue.
Previously, FEMP developed an approach to evaluate the performance of solar photovoltaic (PV) systems at federal sites. The methodology was used to evaluate the performance of 75 federal PV systems and compile statistics regarding KPIs of PV system performance.
It is interesting to observe in Fig. 11 that the case of SSR of 99.44 % (i.e., nearly 100 % of energy consumption is provided by PV and ESS) is dominant in most of impact categories (9 over 12).
The KPIs reported are Availability (% up-time) and Performance Ratio (PR). If the PV system output was zero or less than 5% of the model estimate, then the time interval was counted as “unavailable.” For hours when the PV system was “available,” the measured energy delivery was divided by a reference yield to calculate PR.
