6 FAQs about [Which indicators should be tested for photovoltaic brackets ]

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 are the regulatory levels for photovoltaic systems?

At least three regulatory levels for the production, installation, operation and end of life of photovoltaic systems can be considered. Additionally, the Life Cycle Assessment methodology is also regulated by standards. In this chapter, the three levels are presented.

What impact do the standards have on the PV industry?

These standards have limited impact on the PV industry, where the use of plastic is low and the content of REEs in PV modules is almost non-existent (although the dependence is higher in electronic equipment of BoS).

What are the standards & guidelines for PV electricity?

Additional standards and guidelines have later been published such as the ISO 21930 (Environmental Product Declaration on Construction Products”, International Organization for Standardization (ISO) 2017), and the Product Environmental Footprint Category Rules (PEFCR) for PV electricity (TS PEF Pilot PV 2018).

What are the requirements for regulating PV system design and battery function?

First, to regulate system design and battery function: IEC 62124 for stand-alone PV system design recommendations and PV performance evaluation (including battery testing and recovery after periods of low state-of-charge) in a variety of climatic conditions, and IEC 62509 for battery charge controllers.
