6 FAQs about [Photovoltaic support load performance test]

What is a stand-alone photovoltaic (PV) system test?

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.

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).

What is a stand-alone PV system performance test?

Such tests, however, are beyond the scope of this recommended practice and may require specialized test equipment and procedures. Purpose: An evaluation of stand-alone PV system performance is needed to determine how well the PV array charges the battery and how well the battery is sized for the load.

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.
