What are IEC standards in photovoltaics?

IEC standards in photovoltaics were developed by TC82 “Solar photovoltaic energy systems” . The U.S technical advisory group (USTAG) feeds the input to IEC TC82 standards time to time. Both IEC and American Society of Testing and Materials (ASTM) International had published numerous PV standards in which many are similar and redundant.

How many standards are there for photovoltaic systems?

There are nearly 80 standards applicable to photovoltaic and five working groups in IEC TC82. For necessary safety requirements ‘Quality and Standards’ technologically need to be revised and up to date.

What are the standards for flat plate PV modules?

Standards for flat plate PV modules – covers rack mounting systems, clamping devices, mounting grounding/bonding devices for specific flat plate PV panels that comply with the standard for PV UL1703 or UL 61730–1 (describes the fundamental construction requirements for PV modules for safer operation) and UL61730-2 (for safety qualification test).

What are PV standards?

The standards series has been recognized by the World Bank and the United Nations Industrial Development Organization (UNIDO). Such standards also serve as the basis for testing and certification of components, devices, and systems. Two of the IEC Conformity Assessment Systems deal with PV parts, systems and installations.
