Six Solar Manufacturing Companies Establish Alliance to Standardize 700W+ Modules

NLC India Begins Construction Of 300 MW Solar Power Project In Rajasthan

Trina Solar, a PV and energy storage solutions firm has announced that it has established a “Photovoltaic Open Innovation Ecological Alliance” with five other manufacturers. They claim that this joint initiative would bring standardizing in applying the design of 700W+ PV modules.

Other companies that are part of the alliance are, Astronergy, Canadian Solar, Risen Energy, TCL Zhonghuan and Tongwei. They set up the 700W+ a ‘Photovoltaic Open Innovation Ecological Alliance’ on December 15. It signifies as a milestone of whole industry.

Based on the document issued by the China Photovoltaic Industry Association, the firms have developed a standard dimensions of 700W+ ultra-high power modules. Alongside this, they also decided to develope a “T/CPIA 0003-2022 Technical Specification for Crystalline Silicon Terrestrial Photovoltaic Module Dimensions and Mounting Holes”. These six manufacturers have proposed that 700W modules in all PV companies should adhere to existing agreed industry dimensions (module size: 2384mm x 1303mm. Alongside this, the module long-side vertical hole distance: 400mm/1400mm) and a hole distance of 790mm has been added to the standard.

The firms claim that this would reduce the levelized cost of energy (LCOE) through enhancing module efficiency and power output has become an inexorable trend in the industry. The firms said with the collaborative efforts of PV open innovation ecological alliance, the PV industry has entered 600W+ era three years ago. Nowadays, power output of PV modules has been upgraded from 600W+ to 700W+ with the application of n-type high-efficiency cell technology (TOPCon, HJT, etc) and G12 (210mm) large-format wafer technology.

The initiative, which calls for all PV companies to promote standardization of module dimensions and the industrialization of ultra-high-power and ultra-high-efficiency modules, will push the industry one step further toward industrializing 700W+ PV modules.

The newly upgraded 700W+ Photovoltaic Open Innovation Ecological Alliance will provide great opportunities for both the upstream and downstream chain, while achieving large scale effect, enhancing supply chain efficiencies, boosting production and lowering costs throughout the industrial chain, as a result to accelerate the industrialization of 700W+ products, reduce LCOE and maximize the solar PV value, the manufacturers said.
