In a groundbreaking move toward advancing solar technology, Trina Solar, a global leader in smart photovoltaic (PV) and energy storage solutions, has joined forces with five other major manufacturers—Astronergy, Canadian Solar, Risen Energy, TCL Zhonghuan, and Tongwei—to establish the 700W+ Photovoltaic Open Innovation Ecological Alliance. This collaboration, announced on December 15, marks a significant milestone in the industry’s transition to the era of 700W+ PV modules.
The alliance’s inception follows the launch of a joint initiative on December 11, aimed at standardising and implementing the design of 700W+ PV modules. The manufacturers, recognising the importance of standardisation in advancing the industry, propose that all 700W+ modules adhere to agreed-upon dimensions outlined in the “T/CPIA 0003-2022 Technical Specification for Crystalline Silicon Terrestrial Photovoltaic Module Dimensions and Mounting Holes” document issued by the China Photovoltaic Industry Association.
According to the proposal, the standard dimensions for 700W+ ultra-high-power modules include a module size of 2384mm x 1303mm, with the module’s long-side vertical hole distance set at 400mm/1400mm. Additionally, a hole distance of 790mm has been introduced to further enhance standardisation.
The push for standardisation is driven by a collective goal to reduce the Levelised Cost of Electricity (LCOE) through increased module efficiency and power output. The alliance notes that over the past three years, the PV industry has progressed from the 600W+ era to the current 700W+ era, thanks to the adoption of n-type high-efficiency cell technology, such as TOPCon and HJT, along with G12 (210mm) large-format wafer technology.
The initiative not only calls for the standardisation of module dimensions but also encourages the industrialisation of ultra-high-power and ultra-high-efficiency modules. The upgraded 700W+ Photovoltaic Open Innovation Ecological Alliance aims to create opportunities across the entire PV supply chain, enhancing efficiency, increasing production, and ultimately reducing costs.
By accelerating the industrialisation of 700W+ products, the alliance seeks to maximise the value of solar PV and make strides toward a more sustainable and economically viable future. Trina Solar, aligning with its mission of “Solar Energy for All,” asserts its commitment to delivering higher value to the global solar energy community.
