China's solar giant Hanergy purchases MiaSole

Hanergy will increase MiaSole's factory output to full capacity and retain about 100 of its employees. It also plans to hire additional employees for manufacturing.

The transaction has received regulatory approval from the Chinese and US governments.

On Nov 30, Li said in Beijing that Hanergy had replaced First Solar Inc to become the world's largest maker of thin-film solar modules, with an annual capacity of 3 gigawatts.

MiaSole says it has the world's highest energy efficiency in the manufacture of thin film called CIGS, which stands for the metals copper, indium, gallium and selenide.

 

The technology makes thin-film solar panels more flexible to use.

John Carrington, CEO of MiaSole, said, "MiaSole has advanced solar technology by developing the highest efficiency and lowest-cost CIGS modules, but we needed to align with a strategic partner in order to deploy our technology across a larger global scale."

Hanergy last year acquired Q-Cells SE's subsidiary Solibro, a German maker of thin-film solar panels. Solibro has developed CIGS technology for more than 25 years.

After the completion of the acquisition, Solibro increased its yearly production capacity to 100 megawatts to supply Hanergy's customers in Europe.

The lower efficiency of the thin-film solar panels compared with polysilicon solar cells has long been an obstacle in the industry.

Thin-film solar cells' energy efficiency and lifespan still have lots of room for improvement compared with polysilicon-manufactured solar panels, Meng Xian'gan, deputy director of the China Renewable Energy Society, told a conference in December.

MiaSole's thin-film solar panel efficiency has reached 15.5 percent, said to be the highest in the world.

Carrington said this efficiency will rise to more than 17 percent within two years, and the production cost will drop to below 50 US cents a watt during this time.

"The long-term target is to reduce the unit cost to 33 cents a watt," he said.
