6 FAQs about [How to write a photovoltaic panel measurement report]

How do I calculate the performance ratio of my PV plant?

You need different variables to be able to calculate the performance ratio of your PV plant. On the one hand, these are the solar-irradiation values for the site of the PV plant. You can determine these values using a measuring gage (e.g. Sunny SensorBox) that measures the incident solar irradiation at your PV plant.

What is PV performance ratio?

The performance ratio is a measure of the quality of a PV plant that is independent of location and it therefore often described as a a quality factor. The performance ratio (PR) is stated as percent and describes the relationship between the actual and theoretical energy outputs of the PV plant.

What is the IEC standard for photovoltaic system performance monitoring?

A set of monitoring Standards has been produced by the IEC, titled Standard for Photovoltaic system performance monitoring2. The focus of the IEC standard is on the electrical performance of PV systems, and it does not address hybrids or prescribe a method for ensuring that performance assessments are equitable.

How to evaluate PV system capacity?

A simple method to evaluate the PV system capacity is to determine the nominal DC rating of the system at STC, measure POA irradiance, calculate cell temperature based on module back-side or ambient temperature using Sandia model, and estimate/calculate/determine values for the derate factors familiar to the industry.

Do PV system commissioning standards require performance testing?

This best practice guide is PV System Commissioning or re-Commissioning Guide Supplement to characterize and maximize PV system performance. If a PV system is commissioned using industry standards, then it should produce as much energy as was expected, right? No, PV industry commissioning standards do not call for performance testing.

How do you test a photovoltaic system?

The power generation of a photovoltaic (PV) system may be documented by a capacity test [1, 2] that quantifies the power output of the system at set conditions, such as an irradiance of 1000 W/m2, an ambient temperature of 20°C, and a wind speed of 1 m/s. A longer test must be used to verify the system performance under a range of conditions.
