ENN Solar produces China's first ultra-large PV panel

ENN Solar Energy Co. Ltd. has produced China's first 61-square-foot (5.7-sq-m) high-efficiency, tandem junction thin film photovoltaic (PV) panels using a SunFab Thin Film Line, rated at 60 MW per year, supplied by Applied Materials Inc.

Working together at ENN's facility in Langfang, China, ENN and Applied Materials achieved the milestone just five months after equipment installation. The ultra-large PV panels are nearly four times larger than conventional modules on the market and use Applied Materials' tandem junction technology to deliver higher conversion efficiencies at competitive costs.

"By combining the high efficiency of tandem junction technology with ultra-large [5.7-square-meter] substrates, we're able to deliver modules that dramatically reduce installed cost per watt," said Dr. Rick Wan, general manager of ENN Solar.
