6 FAQs about [Photovoltaic panel performance testing standards]

Can a stand-alone photovoltaic system be tested?

Abstract: Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load. The methodology includes testing the system outdoors in prevailing conditions and indoors under simulated conditions.

What is a standard for photovoltaic systems?

Current projects that have been authorized by the IEEE SA Standards Board to develop a standard. Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load.

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.

Do PV industry standards include performance testing?

PV industry standards for commissioning do not include performance testing. The National Electric Code and the IEC commissioning standard (IEC62446) mention nothing about performance testing.

What is a good test voltage for a PV module?

For example, consider a single-ended test of a PV string with Voc of 475V and a PV module maximum system voltage spec of 1000V. Setting the meg tester’s test voltage to 500V will keep all points in the circuit below 1000V.

Can a PV system be tested if a load changes?

These tests do not cover PV systems connected to an electric utility. Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load (s).
