Standardization of 210 Modules Significantly Boosts The PV Industrial Chain And System Value


Standardization of 210 modules directly benefits the solar industry, project developers as well as engineering, procurement and construction (EPC) companies.


The module standard is expected to be officially released in October by China Photovoltaic Industry Association. Standardization of 210mm wafers, cell and module size will directly result in lower balance of system (BOS) costs, make the supply chain more efficient, and achieve the optimum scale effect.

In addition, industrial technical innovation will be accelerated, reducing manufacturing costs for the industry chain, initial investment of PV systems and ensuring a better internal rate of return (IRR).


Increasing module power and reducing power generation costs have become an inevitable trend. Last November, eight world-leading photovoltaic brands, including Trina Solar, set
about promoting the standardization of 210mm silicon wafer modules in the photovoltaic industry. By May of this year, the 210-standardization process had achieved significant results, which is expected to be formally released in October.

Achieving agreement: Uniform size for 210 modules

On May 26 the China Photovoltaic Industry Association organized an online seminar
on the standardization of module sizes. Fifty experts and representatives of module
manufacturers, developers, system solution providers and third-party organisations,
including Trina Solar agreed on the overall dimensions of modules and technical specifications of mounting holes. Technical details such as cell spacing and design reference standards were also agreed upon to form a group standard. This means 210 module manufacturers, end users and system solution providers have achieved uniformity in technical issues.

Standardization of modules will greatly reduce BOS costs and LCOE, and deliver the
convenience and maximum value of ultra-high power modules and solutions to solar

For 110 half cells (55 whole cells), the length is determined as 2384±2mm, the width
as 1096±2mm, and the positions of the mounting holes in the long side are put at
400/1400±1mm. Following is a breakdown of the dimensions of the three 210

In addition, all 210 module manufacturers will design products in accordance with
the latest international standard IEC/UL 61730.
