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.)
We raised standardizing item of module dimensions in 2016. SEMI PV86-1018 Specification for Crystalline Silicon Photovoltaic Module Dimensions was officially published in 2018. These specifications only applied to crystalline silicon PV modules with 60 and 72 solar cells (system voltage ≤1500V, recommend solar cell size with 156.75mm±0.25mm). The creepage distances of these modules meet the requirement of pollution level 1 or pollution level 2 material items in IEC 61730-1. Except the double-glass and bifacial modules.
As the development of PV technology, the wafer sizes are changing as well as the module dimensions. The institution of IEC TC82 WG8 held a meeting in Shanghai on June 3d, 2019. The standard wafer sizes drafts were discussed, three wafer sizes were clarified for now, they are 156.75.mm, 158.75mm and 166mm. We investigated the module dimensions in the PV industry under this situation. Many companies which are in the lead position of the global PV module shipment ranking attended this investigation this time, such as Jinko, JA, LONGi, GCL, Trina, Yingli, Hanwha Qcell, Chint, CSI and so on. The investigation contents cover all the module dimensions for now and the module dimensions which are about to develop in the next two years.
According to this investigation, the module dimensions changed as the wafer size changed, the module technologies development brought more types of modules, for example, half-cell module, bi-facial module, double-glass module, and so on. Therefore it is urgent to modify the last version of module dimension specifications and normalize the dimensions and mounting positions of different type modules.
The standardizing of module dimensions and mounting positions not only can reduce the management cost by reducing the types of glasses, back-sheets, frames, and so on, but also can reduce the EPC cost by reducing the terminal customers’ holders. Up stream and down stream firms could exchange and share for each others based on these specifications. The terminal module users’ cost will be reduced and the PV modules will be more used and developed. These specifications will promote the PV industry to develop healthily and orderly.



b. Estimate effect on industry.
1: Major effect on entire industry or on multiple important industry sectors - identify the relevant sectors
Sector or Company Information: PV industry

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:
1.The dimensions and mounting hole positions and sizes of Crystalline Silicon Photovoltaic Module used on earth surface ("modules" for short in the rest parts) were specified in these specifications.
2. These specifiations applied to the single-glass or double-glass modules (60 and 72 solar cells) with certain cell size (156.75/158.75±0.25mm), and the certain system voltage (≤1500V), the creepage distances of these modules meet the requirement of pollution level 1 or pollution level 2 material items in IEC 61730-1.
3. These specifiations applied to the single-glass or double-glass modules(120 and 144 solar cells) with certain cell size(156.75/158.75±0.25mm×78.37/79.37/83±0.25mm), and the certain system voltage(≤1500V), the creepage distances of these modules meet the requirement of pullution level 1 or pollution level 2 material items in IEC 61730-1.
4. 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.
