Date Prepared: 10/28/2024Revised (if Applicable):

Document Number: 7315
SNARF for: New Standard: Test Method for PV modules intensify aging in cold environmental conditions

Originating Global Technical Committee: Photovoltaic
Originating TC Chapter: China
Task Force (TF) in which work is to be carried out: PV Module Task Force
Note: If a new task force is needed, also submit a task force organization form (TFOF)

1. Rationale:
a. Describe the need or problem addressed by this activity.
(Indicate the customer, what benefits they will receive, and if possible, quantify the impact on the return on investment [ROI] if the Document is implemented.)
The rapid development of the photovoltaic market and the growth of photovoltaic installed capacity across the country have put forward new requirements for the reliability of photovoltaic modules. In view of the frequent occurrence of extreme weather in cold regions, the industry urgently needs to take into account the accelerated aging test sequence standards of cold environment differences to ensure the long-term stable operation of modules in cold environments.
There is no specific test standard for photovoltaic modules in the industry for applications in cold climate environments, while this standard provides an aging test method applicable to cold environment conditions on the basis of type identification, so that the performance and reliability differences between modules with different designs, materials and processes can be more selectively compared, and the aging failure mode of photovoltaic modules under long-term use can also be reproduced. It helps to identify weaknesses in the design of PV module products and improve them.


b. Estimate effect on industry.
2: Major effect on an industry sector - identify the relevant sector
Sector or Company Information: Photovoltaic Module

c. Estimate technical difficulty of the activity.
II: Some Difficulty - Disagreements on known requirements exist but developing consensus is possible

2. Scope:
a: Describe the technical areas to be covered or addressed by this Document development activity. For Subordinate Standards, list common concepts or criteria that the Subordinate Standard inherits from the Primary Standard, as well as differences from the Primary Standard:
The scope of application of this standard is mainly crystalline silicon photovoltaic modules used on the ground under cold environmental conditions.
The technical content of this standard includes: scope, terminology, sampling, sample characterization, cryogenic storage and low-temperature operation, cold environment enhanced aging test methods, test reports, etc.

b: Expected result of activity
New Standard or Safety Guideline (including replacement of an existing Standard or Safety Guideline)

5. Safety Considerations:
The resulting document is expected:
NOT to be a Safety Guideline

NOTE FOR "to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is NOT technically sound and complete - Refer to Section 15.1 of the Regulations for special procedures to be followed.

NOTE FOR "NOT to be a Safety Guideline": When all safety-related information is removed from the Document, the Document is still technically sound and complete.

6. Intellectual Property Considerations:
Note: Both a: and b: below should be checked for Revision of existing Standard(s) and Safety Guideline(s).

a. For a new Standard or Safety Guideline and for any part to be modified or added in a Revision of published Standards and Safety Guidelines:


If "patented technology is intended to be included in the proposed Standard(s) or Safety Guideline(s) " is selected above, then also check one:


b. For Revision, Reapproval, Reinstatement, or Withdrawal of existing Standard(s) and Safety Guideline(s):
there is no known material patented technology necessary to use or implement the Standard(s) and Safety Guideline(s)

c. The body of the Document and any Appendices, Complementary Files, Related Information sections, or Various Materials that may or may not be a part of the Document by reference:
the incorporation of Copyrighted Item will NOT be required



NOTE FOR ‘the use of patented technology or the incorporation of Copyrighted Item(s) is NOT required’: If in the course of developing the Document, it is determined that the use of patented technology or Copyrighted Item(s) is necessary for the Document, the provisions of Regulations § 16 must be followed.

NOTE FOR ’will incorporate Copyrighted Item’: A copyright release letter must be obtained from the copyright owner prior to publication.
