Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum
NOTE 1 The terms "PV", "photovoltaic" and "solar photovoltaic" can be read and used interchangeably and without the need for stating each term to show that each is applicable and
especially when a PV plant is built in a hilly area or in an area where labor costs are high. Many PV plants use a single grounding electrode at the PV inverter instead of a large grounding grid
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).
In addition to referencing international electro-technical photovoltaic standards such as IEC 61215, IEC 61646 and IEC 61730, typical standards from the building sector are also included, such as: EN 13501 (Safety in case of fire); EN 13022 (Safety and accessibility in use); EN 12758 (Protec-tion against noise).
The IEC PV standards comprise IEC technical committee 82 solar PV Energy System (IEC TC82) which develops and adopts all Photovoltaic related standards. There are nearly 80 standards applicable to photovoltaic and five working groups in IEC TC82.
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.
Contribution of UL technical expertise in PV modules emerges from second edition of IEC 61730. There are more than a thousand safety standards including PV related standards in Underwriters Laboratories Inc. PV specific UL standards are shown in Table 5. UL standards are recognized worldwide for product safety. Table 5.
Though many countries have their own national PV standards, the majority are based on the standards developed by International Electrotechnical Commission (IEC) established in the year 1995 which is the world’s leading standards organization that develops and publishes the international standards for electrotechnology.
