Modules included in this chart of the current state of the art have efficiencies that are confirmed by independent, recognized test labs—e., NLR, AIST, JRC-ESTI and Fraunhofer-ISE—and are reported on a standardized basis. . Plane of Array Irradiance, the sum of direct, diffuse, and ground-reflected irradiance incident upon an inclined surface parallel to the plane of the modules in the photovoltaic array, also known as POA Irradiance and expressed in units of W/m2. Performance Ratio based on measured production. . The performance index is the ratio of measured energy from a PV system to the predicted energy using a PV performance model. Learn how NLR can help your team with certified efficiency measurements. Or download. . Why do we need a performance guarantee for a large photovoltaic system? Documentation of the energy yield of a large photovoltaic (PV) system over a substantial period can be useful to measure a performance guarantee,as an assessment of the health of the system,for verification of a performance. . The IEC 61724 “Photovoltaic system performance” series of standards is the best available source that defines parameters such as “performance ratio” and “performance index”. The purpose of this document is to clarify the logic behind IEC 61724 and its vocabulary.
