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.)
Since the launch of the photovoltaic module dimension standardization project in 2016, the industry has gone through multiple stages of development: In 2018, SEMI PV86-1018 Specification for Crystalline Silicon Photovoltaic Module Dimensions was officially released, providing a basic standard for early module production and application. With the rapid iteration of technology, the revision of the standard was initiated in 2019, and the formulation of the new version of the standard was completed in 2023. The current standard has significantly expanded its coverage, applying to crystalline silicon photovoltaic modules with cell sizes of (156.75±0.25) mm, 158.75mm±0.25mm, 166mm±0.25mm, 182mm±0.25mm, and 210mm±0.25mm (including full-cell and half-cell), and with creepage distances meeting the requirements of pollution level 1, 2, and material group I specified in IEC 61730-1.
In recent years, breakthroughs in photovoltaic technology have driven rectangular wafers to become the mainstream cell format, leading to significant changes in module dimensions. To better align with industry needs, we initiated a dedicated survey on module dimensions, covering leading global manufacturers with top shipment volumes, including Jinko, LONGi, JA Solar, Trina Solar, Tongwei, Chint, Canadian Solar, and DAS. The survey encompassed both the dimensional parameters of current mainstream modules and the specifications of new models planned for promotion over the next two years.
increasingly prevalent. Third, the overall size of modules continues to increase, along with their aspect ratios. However, the spacing of mounting holes has not been adjusted accordingly, leading to new challenges in mechanical performance.
Therefore, the draft proposes to remove the content related to battery modules with dimensions of (156.75±0.25) mm, 158.75±0.25 mm, and 166±0.25 mm, and instead introduce specifications for the external dimensions and mounting hole positions of rectangular battery modules. From a system-level perspective, the design of mounting holes will be optimized by scientifically adjusting their layout. This approach not only ensures the structural integrity of modules across various application scenarios but also helps reduce the initial investment cost of terminal projects, ultimately providing strong technical support for the large-scale and standardized development of the photovoltaic industry.

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 Standard specifies the overall dimensions of crystalline silicon photovoltaic modules and size of mounting holes of frame modules.These specifiations applied to crystalline silicon PV modules with182mm±0.25/210mm±0.25mm （including full-cell and half-cell）, The creep age distances of these modules meet the requirement of pollution level 1 or pollution level 2 material items in IEC 61730 - 1.This specification includes the dimensions in length, width, height of the PV module, the locations and the sizes of the mounting holes, and other technical specifications.
