HT-SAAE's Milky Way module surpasses 300 W of mass production output power


China’s Shanghai Aerospace Automobile Electromechanical Co., Ltd. (HT-SAAE) said Wednesday that its N-type PERT high-efficiency mono-crystalline silicon solar module had for the first time exceeded 300 W of mass production output power.

The government-owned company cited Germany’s TÜV Rheinland, which recently tested and certified its Milky Way modules based on 60 pieces measuring 156 mm by 156 mm.

HT-SAAE’s N-type PERT module employs independently developed N-Type high efficiency cell technology. The mass production output power for N-type PERT mono-crystalline modules is 10 to 15 W higher than the average industrial level of traditional mono-crystalline PV modules, the company said. Cell-to-module loss is 2% lower than traditional P-type modules while the module’s efficiency levels surpass 18.4%, it added.

HT-SAAE reports that the output power for the module has increased from 285 W in February to 300 W in October. The company said the technical breakthrough makes it a leader in the technology, adding that the achievement “will no doubt provides significant value to the expansion of HT-SAAE’s overseas markets and greatly improve its client’s ROI.”

The module also scored the highest industry load level (10800Pa) tested and certified by the CSA Group and passed double the IEC reliability test, with induced degradation of DH2000, TC400 and HF20 all below 3%.

“This test further proves that [the] Milky Way solar module can better adapt to severe environments to satisfy customer demand in areas with high wind and snow pressures, especially in high latitude areas like northern Japan, Germany, Netherlands and heavy snowfall areas such as Eastern Europe,” the company said.

Zhang Zhongwei, HT-SAAE’s chief technology officer, added, "The efficiency improvement on Milky Way’s mass production output power can reduce module installation quantity and the levelized cost of electricity and meanwhile shorten the investment payback period.”

HT-SAAE said it would increase investment on research and development with the aim of further raising its modules’ mass production output power up to 310 W by making technical breakthroughs on its existing Highway and Milky Way technology.
