Standard Upgrade! See how the new national standard is redefining the safety and durability of BIPV.

• Material Specifications: Specifies the selection criteria for materials including glass, photovoltaic cells, interlayers, busbars, insulating tapes, and leads.
• Technical requirements: Cover more than 20 indicators, including appearance quality, dimensional deviations, curvature, insulation properties, leakage current under wet conditions, environmental resistance (such as UV exposure, damp-heat, thermal cycling, and freeze-thaw cycles), mechanical performance (static/dynamic loads, wind pressure resistance, impact resistance, etc.), and electrical safety performance.
• Test Method: The test procedures, instruments, and acceptance criteria for each performance characteristic are described in detail. Several of these tests reference international standards such as IEC 61215-2.
• Inspection Rules: Distinguish between factory inspection and type testing, and clearly define the sampling plan, batch grouping rules, and acceptance criteria.
• Packaging and Labeling: Each product must be affixed with a label containing electrical parameters, manufacturer information, and other relevant details, and shipping and storage conditions must also be specified. III. Key Highlights Regarding “Thin-Film Solar Modules”

• The allowable number and size specifications for punctate and linear defects are the same as those for crystalline silicon module components, but adaptive provisions have been made to account for the characteristics of thin-film structures.

• In the visible area, thin-film batteries should not have any pores or visible corrosion areas covering more than 10% of the effective circuit area. Three typical structures of thin-film photovoltaic laminated glass are specifically illustrated (see 5.2.1).
