On December 25, 2025, DAH Solar held a celebration in Hefei, marking the 5th anniversary of its Full-Screen Anti-Dust technology and launching its new V6 high-efficiency PV module series. At this key time for the solar industry, DAH Solar is addressing challenges by integrating Full-Screen Technology with high-efficiency modules, advancing the product to mass production. The series achieves a power output of 650W and 24.06% efficiency.
The V6 high-efficiency PV module has four core technologies. It has large-format cells. They are arranged in a smart layout. This design gives more power in the same space. Besides, it uses busbar-free cell technology. This makes it more efficient and stronger. It also has half-cell and light-reflecting features. These help it last longer and produce more energy.
The Full-Screen technology was first shown in 2021. Now, after five years, it has been shipped to many countries, with total shipments reaching 4.5 GW. It also has patents in 18 countries and regions. Building on this success, this step helps DAH Solar strengthen its role as a top global company in solar technology.
The journey of Full-Screen technology began in 2019 with the idea of solving dust buildup on solar panels. Through persistent innovation, this idea became a reality. In 2022, the Full-Screen PV modules passed all TÜV tests and shipped over 500MW worldwide, reaching markets like Brazil, Germany, Japan, and China. In 2023, the Full-Screen Anti-Dust 2.0 dual-glass module was launched, proving an 11.5% power gain in TÜV NORD outdoor tests. In 2024, the 3.0 DBB module achieved a leap in conversion efficiency. In 2025, the 4.0 module opened a new era for side installation, while the V6 series broke the 24% efficiency barrier. Our consistent focus on improvement is what made the Full-Screen PV module a leading product.
Looking ahead, DAH Solar will continue to focus on innovation. The company aims to improve product efficiency and reliability further. It will keep expanding its global presence and developing new solutions for a low-carbon future.
