The performance ratio informs you as to how energy efficient and reliable your PV plant is. With the performance ratio you can compare the energy output of your PV plant with that of other PV plants or monitor the status of your PV plant over a prolonged period.

By implementing this approach, different types of power losses in PV systems, including both array capture losses (i.e. temperature loss, mismatching and soiling losses, low irradiance, spectral, and reflection losses, module quality degradation, and snow loss) and system losses (i.e. inverter loss, cabling loss, inverter power limitation loss .

The PR is a popular metric used to indicate the total generation of the output power of PV installations [2]; wherein theory, 100% shows no losses associated with the PV installation. In existing PV installations, as a worldwide point of view, the PR is usually ranging from as low as 10–20% up to 95%.

The performance loss rate (PLR) represents both reversible (e.g., soiling) and irreversible (e.g., material degradation) losses [1, 2] that can occur in a photovoltaic (PV) power plant and is an important parameter for performance modeling, monitoring, and operation and maintenance (O&M). In PV performance modeling, PLR is applied to account .
