Conferences > 2023 IEEE 50th Photovoltaic S... The detailed procedure to estimate two key performance indicators (KPIs) of Solar PV power plant i.e., Performance Ratio (PR) & Capacity Utilization Factor (CUF) using statistical methods has been presented.
Technical Availability (or Uptime), Contractual Availability and Energy-based Availability are three closely related indicators to measure whether the solar PV power plant is generating electricity. The latter two KPIs are explained in section 10.5. Solar PV power plant/O&M service provider KPIs.
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 ).
By comparing inverter level-specific yields within a power plant, it is possible to detect which of an inverter are performing better than others. CUF is output of the plant compared to theoretical maximum output of the plant in specific period of time.
