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.

This study explores the technical and economic performance of utility-scale PV plus storage systems. Co-Located? AC = alternating current, DC = direct current.
The multi-objective optimization results, incorporating load match ratio, grid flexibility factor, and lifetime levelized cost of energy, indicated that integrating PV panels, static battery storage, and EVs can improve grid flexibility in building energy supply systems with TOU pricing.
Therefore, the integration of PV-energy storage systems can greatly reduce the dependence on the power grid, thereby facilitating more flexible regulation for building energy systems. The optimal storage capacities are determined by solving the established MILP model by CPLEX for the PV-TES system, PV-BES system, and PV-HES system.
In all cases the 30% ITC is applied to the PV portion of the system. Benefit/cost ratios are calculated by dividing annualized benefits by costs. The PV-only system has the highest benefit/cost ratio. These results follow historical trends that have resulted in very limited deployment of PV plus storage systems.
