Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 38388—2019
This standard specifies the test pieces, test items and methods, test sequence and result expression and test report for the test methods of building photovoltaic curtain walls and photovoltaic skylights. It is applicable to laboratory testing of building curtain walls and skylights with photovoltaic power generation functions.
Background of Standard Formulation
With the transformation of the global energy structure and the rise of the concept of green buildings, photovoltaic technology is increasingly used in buildings. In order to standardize the test methods of photovoltaic curtain walls and skylights and ensure their safety and functionality, GB/T 38388—2019 came into being.
Technology Evolution Analysis
Compared with traditional building curtain walls, photovoltaic curtain walls and skylights have achieved the combination of power generation and building functions in terms of function. This standard combines existing specifications such as GB/T 15227 and GB/T 34555 to deepen the testing methods for photovoltaic components.
Comparison of standard frameworks
| Dimensions | GB/T 38388—2019 | GB/T 15227 | JG/T 492 |
|---|---|---|---|
| Scope of application | Photovoltaic curtain wall and skylight detection | Airtightness, watertightness and wind pressure resistance of building curtain walls | General technical requirements for photovoltaic components for buildings |
| Core indicators | Maximum power, insulation, wet leakage current | Airtightness, watertightness, wind pressure resistance | Interlayer deformation performance, impact resistance |
| Testing methods | Electroluminescence testing, mechanical properties testing | Pressure box method, water pressure sealing test | Thermal cycle test, wind impact test |
Implementation suggestions
Case analysis:A large public building plans to use a photovoltaic curtain wall system. According to the GB/T 38388-2019 standard, the following aspects should be focused on:
- Specimen selection: Ensure that the specimen represents a typical photovoltaic curtain wall structure and contains at least three photovoltaic components.
- Testing order: Prioritize electrical performance testing, followed by mechanical and physical performance testing.
- Data recording: Record the maximum power attenuation rate and insulation changes in detail.
