The IEEE 1526-2020 standard specifies procedures for testing the performance of stand-alone photovoltaic (PV) systems. These tests are intended to verify system design adequacy and performance claims for full systems with a defined load.

The standard specifies test methods and procedures for evaluating the performance of stand-alone photovoltaic systems, which include PV modules, charge controllers, batteries, and loads. These tests can be performed in a test facility or in the field by qualified personnel using appropriate test equipment. The recommended practice specifies tests that can be performed in both actual outdoor circumstances and simulated indoor conditions. It should be emphasized that this standard does not address issues such as system safety, component reliability, quality, or code compliance.

The goal of this standard is to provide a framework for evaluating the performance of stand-alone PV systems, with a particular emphasis on how well the PV array charges the battery and the battery's sizing appropriateness for the load. The processes defined in the standard are intended to assist various stakeholders, including designers, manufacturers, system integrators, users, and laboratories, in conducting stand-alone PV system performance evaluations.

It is crucial to note that the recommended approach does not apply to PV systems that are connected to an electric utility, and the test results are only applicable to the tested system. Any changes to the PV system or load demand re-running the tests on the updated system. Furthermore, the standard recognizes that performance tests on certain loads, such as lamps, may be required but are outside the scope of this recommended practice and may necessitate specialist test equipment and techniques.
