700W 이상 PV 모듈의 산업화를 가속화하는 것을 목표로 하는 700W+ 태양광 오픈 혁신 생태 연합(Photovoltaic Open Innovation Ecological Alliance)에 따르면, 태양광 모듈 크기 표준화를 통해 공급망의 효율성이 향상되고, 생산이 늘어나며, 비용이 절감될 것입니다.
Trina Solar has announced the formation of the 700 W+ Photovoltaic Open Innovation Ecological Alliance. The group – which also includes Astronergy, Canadian Solar, Risen Energy, TCL Zhonghuan and Tongwei – plans to standardize the design of solar modules above 700 W in size.
The alliance calls for module manufacturers adhere to existing agreed industry dimensions of 2,384 mm by 1,303 mm. A hole distance of 790 mm has been added to the standard. This builds on the T/CPIA 0003-2022 Technical Specification issued by the China Photovoltaic Industry Association.
In recent years, the power output of solar modules has jumped from 500 W to 700 W, and the size of modules have increased along with the wattage. In 2021, for example, Risen Energy released the 132-cell NewT@N panel based on 210 mm n-type monocrystalline multi busbars cells with a half-cut design. The high-wattage module size conforms to the recommended standard of 2,384 mm x 1,303 mm x 35 mm.
Having large modules presents some challenges in terms of weight on a roof, and ease of mounting on trackers or racking. But a lack of standardization presents several challenges, not only in production, but in fitting to infrastructure.
The 700W+ alliance sees standardization as a way of reducing balance of system costs while also cutting the levelized cost of electricity. Ultimately, standardization will enhance supply chain efficiencies, boost production, and lower costs, the alliance claims.
