Despite only being released last year, the G12 210mm large area-size wafer has quickly attracted supporters, with more than 120GW of cell manufacturing expansions announced and a solar ecosystem evolving around it. Carrie Xiao analyses the figures behind its rise.
In the first of a two-part feature Joseph C. Johnson, technology and quality senior analyst at Clean Energy Associates, explores recent polysilicon price volatility and its impact on the upstream solar sector.
The PV industry has recently witnessed the launch of a new wave of high-efficiency, high-power modules incorporating state-of-the-art technology. As China and other countries around the world embrace grid parity, modules with higher conversion efficiency and output are becoming increasingly favoured by the market.
Much has been written and voiced over the past couple of months in the PV industry, following the so-called China-531 policy announcement that finally provided a wake-up call to Chinese manufacturers that their domestic end-market was not going to be allowed to maintain its near-exponential growth characteristics.
Major metallization paste producer Heraeus Photovoltaics has extended its supplier status with major China-based integrated PV module manufacturer, Tongwei Solar to collaborate on next-generation high-efficiency wafer and solar technologies.
There are many key metrics worth listing at the end of each year in the solar industry. In terms of the upstream/manufacturing side, two jump out as leading indicators for the year ahead.
The first is to rank the top-10 producers of the solar cells during the year.
Three major Chinese PV manufacturers, Longi Silicon Materials, Trina Solar and Tongwei, via its polysilicon subsidiary, Sichuan Yongxiang, are to form a Joint Venture (JV) to own and operate a previously planned 5GW monocrystalline silicon ingot pulling production plant in Lijiang City, Yunnan Province, China, by Longi.
