Trina Photo voltaic has introduced the formation of the 700 W+ Photovoltaic Open Innovation Ecological Alliance. The group – which additionally contains Astronergy, Canadian Photo voltaic, Risen Vitality, TCL Zhonghuan and Tongwei – plans to standardize the design of photo voltaic modules above 700 W in measurement.
The alliance requires module producers adhere to current agreed business dimensions of two,384 mm by 1,303 mm. A gap distance of 790 mm has been added to the usual. This builds on the T/CPIA 0003-2022 Technical Specification issued by the China Photovoltaic Business Affiliation.
In recent times, the facility output of photo voltaic modules has jumped from 500 W to 700 W, and the dimensions of modules have elevated together with the wattage. In 2021, for instance, Risen Vitality launched the 132-cell NewT@N panel primarily based on 210 mm n-type monocrystalline multi busbars cells with a half-cut design. The high-wattage module measurement conforms to the really useful commonplace of two,384 mm x 1,303 mm x 35 mm.
Having giant modules presents some challenges when it comes to weight on a roof, and ease of mounting on trackers or racking. However a scarcity of standardization presents a number of challenges, not solely in manufacturing, however in becoming to infrastructure.
The 700W+ alliance sees standardization as a means of decreasing steadiness of system prices whereas additionally reducing the levelized price of electrical energy. Finally, standardization will improve provide chain efficiencies, enhance manufacturing, and decrease prices, the alliance claims.
