Trina Solar seeks to firm up PV supply chain with massive new production facility

Trina Solar, one of the world’s leading solar manufacturers, has kicked off construction of a massive new production facility which will cover almost the entire PV manufacturing chain from polysilicon production to modules based on 210 and N-type technology.

The new Trina Solar New Energy Industrial Park is being built in Xining, the provincial capital of the province of Qinghai, in China, and construction has been divided into two phases, with the first phase due to be completed by the end of 2023.

Once fully built at the end of 2025, Industrial Park is expected to turn out 300,000 tonnes of industrial silicon, 50,000 tonnes of high-purity polysilicon, 35GW of monosilicon, 10GW of wafer slices, 10GW of solar cells, 10GW of modules, and 15GW of auxiliaries for modules.

At the end of phase one of construction the facility is expected to yield an annual output of around a third of the above final totals.

Trina Solar hopes that the New Energy Industrial Park will lead the way in improving the industrialisation of next-generation N-type cell technology and help to guide the industry as a whole towards switching to N-type solar modules.

But Trina is also hoping that its efforts will deliver more control over the company’s supply chain to deliver on the high volume of solar products that customers require.

Alongside the construction mile marker is yet another efficiency world record for Trina Solar, who achieved solar efficiency of 24.5% for its proprietary industrial larger-area 210mm×210mm high-efficiency PERC solar cell.

This marks the 24th time that Trina Solar has broken the world record.

“We are proud to announce the latest achievements developed by our technical team,” said Dr Yifeng Chen, head of high efficiency cell and module R&D centre in Trina Solar.

“PERC is a very mature industrial technology with the lower cost. Our latest achievement indicates Trina Solar R&D team’s vigorous and innovative capabilities in mature technology in mass production.

“We are dedicated to making continuous R&D investment in the technology of mass production and creating higher value for our customers.”
