Solar Industry Giants Establish 700W+ Photovoltaic Open Innovation Ecological Alliance

By Editor


Trina Solar, in collaboration with five manufacturers, Astronergy, Canadian Solar, Risen Energy, TCL Zhonghuan, and Tongwei, solidified the formation of the 700W+ Photovoltaic Open Innovation Ecological Alliance.

This alliance marks a significant leap in the solar industry, signaling the adoption of 700W+ photovoltaic (PV) modules as the new standard.

The genesis of this milestone commenced on December 11, when these manufacturers jointly launched an initiative aimed at standardizing and implementing the design of 700W+ PV modules. This development represents a pivotal moment as the entire industry transitions into the PV 700W+ era.

The alliance, building upon the established 700W+ ultra-high power module specifications, aligns with the T/CPIA 0003-2022 Technical Specification for Crystalline Silicon Terrestrial Photovoltaic Module Dimensions and Mounting Holes issued by the China Photovoltaic Industry Association.

Under these guidelines, the six manufacturers advocate for uniformity among 700W+ modules across PV companies, maintaining agreed-upon industry dimensions (module size: 2384mm x 1303mm; module long-side vertical hole distance: 400mm/1400mm), while adding a standardized hole distance of 790mm.

The primary goal behind this initiative is to drive down the Levelized Cost of Energy (LCOE) by amplifying module efficiency and power output, a trajectory that has become an inevitable trend within the industry.

The alliance emphasized that the collaborative efforts of the PV open innovation ecological alliance propelled the industry into the 600W+ era three years prior. Now, with advancements such as n-type high-efficiency cell technology (TOPCon, HJT) and G12 (210mm) large-format wafer technology, the power output of PV modules has surged from 600W+ to 700W+.

This initiative urges all PV companies to champion the standardization of module dimensions and the industrialization of ultra-high-power and ultra-high-efficiency modules. It is poised to propel the industry toward the widespread adoption of 700W+ PV modules.

The 700W+ Photovoltaic Open Innovation Ecological Alliance promises substantial opportunities for both upstream and downstream chains. Its implementation is expected to enhance supply chain efficiencies, escalate production, and drive down costs across the industrial chain. Consequently, this acceleration in the industrialization of 700W+ products is projected to reduce LCOE and maximize the value of solar PV, according to the manufacturers.
