This article uses Ansys Workbench software to conduct finite element analysis on the bracket, and uses response surface method to optimize the design of the angle iron structure that makes up the bracket. The overall model of the bracket before and after optimization is analyzed and compared.
IEC 61730-1:2016 specifies and describes the fundamental construction requirements for photo-voltaic (PV) modules in order to provide safe electrical and mechanical operation. Specific topics address the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses.
the mounted aluminum framed PV panels (i.e., other PV technologies or ground mount systems), EPA recommends that an installer certified by the North American Board of Certified Energy Practitioners (NABCEP) determine the ideal system for the project’s unique building environment.
Long-term field degradation studies indicate 0.5-0.8 percent for monocrystalline and polycrystalline modules. Degradation is higher for thin-film modules at 0.7-1.0 percent. New PV module designs generally have improved degradation rates.

6 FAQs about [Acceptance specification for thickness of photovoltaic bracket]
What are the standards for photovoltaics?
There are numerous national and international bodies that set standards for photovoltaics. There are standards for nearly every stage of the PV life cycle, including materials and processes used in the production of PV panels, testing methodologies, performance standards, and design and installation guidelines.
What is solar photovoltaic bracket?
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 alloy, carbon steel and stainless steel. The related products of the solar support system are made of carbon steel and stainless steel.
What standards should BIPV comply with?
From the viewpoint of PV, BIPV should comply with the standards for conventional PV modules such as IEC 61215 (design qualification, etc.) and IEC 61730 (construction requirements, etc.). Many BIPV modules have a laminated glass configura-tion.
What is a tolerance on a PV module nameplate?
Tolerances on nameplate: “Uncertainty”, or better tolerance statement related to values of electrical parameters on the nameplate of the PV module as given by the manufacturer. This will also be important for the upcoming revision of EN 50380.
Why do PV modules need IEC standards 61215 & 61646?
These qualification tests have shown to adequately identify design, material, and process flaws that could lead to premature field failures. Consequently, PV module customers have come to appreciate the criticality of the tests set forth in IEC standards 61215 and 61646.
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.
