On October 12th, the 2.5GW high-efficiency heterojunction battery project of Dali Huasheng in Dali Economic and Technological Development Zone of Dali Bai Autonomous Prefecture was officially put into production. This is the first 5GW high-efficiency photovoltaic heterojunction manufacturing project in our province, covering an area of nearly 700 mu, mainly producing 210 heterojunction battery chips and components. The first phase 2.5GW battery project adopts the most advanced double-sided microcrystalline process, and is equipped with new technologies such as silver-copper slurry and light-to-film. The average conversion efficiency of the first batch of battery chips is 25.23%, and the highest conversion efficiency of single chip is 25.69%. It is expected that the average production efficiency will reach 25.5% in the future, supporting the gradual realization of 720W+ production and delivery of supporting components, and promoting the reduction of power generation cost and the improvement of investment return of large-scale ground power station projects around.

[SMM PV News] At an altitude of 4,700 meters! The largest PV project in the middle and lower reaches of the Yarlung Zangbo River in Tibet has been completed.
Recently, the 850 MW Phase I of the Luobusha PV project in Qusum County, Tibet, constructed by PowerChina, successfully passed completion acceptance, providing important support for easing regional power supply-demand tensions and strengthening the plateau energy supply barrier. The Luobusha PV project in Qusum County, Tibet, covers an area of approximately 4,289.59 mu, with a total installed capacity of 850 MW. It is the first batch of key commercial PV projects at the Yazhong Clean Energy Base in Tibet and the largest PV clean power generation project in the middle and lower reaches of the Yajiang River. The project is developed in four phases, with Phase I at 200 MW and an average elevation of 4,700 meters. Chengdu Engineering Corporation under PowerChina undertook the construction of the 220 kV booster station, 50 MW PV area, 20.74 km transmission line, and expansion of the opposite-side substation; Sinohydro Bureau 9 undertook the construction of the 150 MW PV field area, installing a total of 348,000 PV modules, along with 64 box-type transformers and 704 inverters.
