6 FAQs about [Technical requirements for photovoltaic steel brackets]

What is solar photovoltaic bracket?

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 types of solar photovoltaic brackets are used in China?

At present, the solar photovoltaic brackets commonly used in China are divided into three types: concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations.

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.

What are the different types of solar PV installations?

It is possible to divide the solar PV installation into two groups namely, Low power and High power. Low power PV installations are normally roof-top and microgrid, where the consumer has invested mainly for self-consumption and probably feed excess to the grid.

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.
