Introduction
Technical interpretation of the national standard for photovoltaic vacuum glass
| Project | Technical requirements | Test methods |
|---|---|---|
| Appearance quality | The appearance of photovoltaic vacuum glass should be free of breakage, cracking, bending and dislocation that affect installation. | Visually inspect at an illumination of not less than 1000lx, and record the type and location of defects. |
| Dimensional deviation | The length and width deviations should comply with the provisions of Table 2, and the diagonal difference should not exceed 0.2% of the average length. | Measure with a steel tape measure or steel ruler, and calculate the deviation percentage. |
| Curvature | The bow curvature of flat photovoltaic vacuum glass should not exceed 0.3%. | Place the sample vertically, measure the maximum gap and calculate the curvature according to the formula. |
Background of standard formulation and analysis of technological evolution
GB/T 34337-2017 Photovoltaic Vacuum Glass is an industry standard proposed by China Building Materials Federation. The main drafting units include China Building Materials Inspection and Certification Group Co., Ltd., Beijing Xinliji Vacuum Glass Technology Co., Ltd., etc.
With the development of photovoltaic technology and the increase in demand for building energy conservation, photovoltaic vacuum glass, as an emerging product, has broad application prospects in the field of construction. The formulation of this standard fills the gap in the field of domestic photovoltaic vacuum glass and standardizes the technical requirements and testing methods of the product.
Implementation suggestions
- Manufacturers should strictly follow the standards for raw material procurement, production process control and quality inspection.
- It is recommended to establish a complete quality traceability system to ensure that each batch of products meets the technical requirements.
- During the construction and installation process, the test conditions and methods in the standards should be followed to ensure the stable performance of photovoltaic vacuum glass.
