Key Performance Indicators for Solar PV Plants. Key Performance Indicators for Solar PV Plants. Specific yield (kWh/kWp) is the energy (kWh) generated per kWp module capacity installed over a fixed period of time. Indirectly it indicates the number of full equivalent hours a plant produced during a specific time frame.
Solar cell key performance indicators Solar cell KPI allow quantitative monitoring of the most significant production parameters. In this work, the selected KPI is the Laminated Unit Power (Lam-UP) which represents the average power produced by cells that can be laminated (power higher than 3.650 W and without any aesthetic defect).
Mapping and Geospatial Analysis: Advanced mapping techniques using KPI data allow for a comprehensive assessment of PV performance across regions, supporting tailored operations and early-stage design considerations for new PV projects.
The performance ratio (PR) is stated as percent and describes the relationship between the actual and theoretical energy outputs of the PV plant. It thus shows the proportion of the energy that is actually available after deduction of energy loss (e.g. due to thermal losses and conduction losses ).
The average energy ratio of 74.6% is close to the median of 76.0%, confirming that the distribution is not dominated by the outliers. It is unrealistic to assume the PV systems will deliver 100% of the model-estimated performance due to the associated maintenance, staff time and attention, and expense required.
Statistical Summary of Key Performance Indicators Across All 75 PV Systems Availability ranges from 31% to 100% with an average of 95.1% (Table 5). For each timestep (ideally 15-minute or one-hour intervals), the measured production was compared to the modeled production.
