Trina Solar and Tongwei have unveiled a multi-billion-dollar collaboration which will see the two companies invest in and co-develop multi-gigawatt solar supply facilities.

Leading solar module manufacturer JinkoSolar has signed a long-term purchase agreement with solar polysilicon and cell provider Tongwei, worth nearly 100,000MT.

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.

Severe floods in southeastern China have forced the closure of a polysilicon facility owned by Tongwei, dealing yet another blow to the solar industry’s supply chain.

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.

As cell output tops 20GW and annual revenues exceed RMB 10 billion, PV Tech’s Carrie Xiao speaks to Tongwei Solar to determine the secrets behind its success.

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.
