6 FAQs about [Photovoltaic support stability test standard]

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.

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.

Can a PV system be tested if a load changes?
