DAH Solar’s Full-Screen Technology Demonstrates 11% Energy Gain for Solar PV Modules As frameless PV modules are gradually becoming a mainstream trend in the industry, PV magazine had an interview with DAH Solar’s R&D Director, Dr. Jiang Chengyin, about the company’s design for its 3.0 Full-Screen product version further improves energy yield while lowering costs and reducing the likelihood of fractures. What is the “Full-Screen” technology for solar modules? Dr. Jiang Chengyin: Regular solar modules have frames that protrude above the glass surface, causing dust to accumulate since rainwater can't flow off quickly. Through our patented design, we ensure the frame is flush with the surface, allowing rainwater to smoothly run off and carry away dust, achieving a self-cleaning effect. Based on outdoor performance tests, at an installation angle of around 5 degrees, which simulates the typical installation angle on most domestic color steel tile roofs, our Full-Screen modules can achieve an annual energy gain of approximately 11%. With the elimination of traditional aluminum frame wrapping, can the Full-Screen's flat edge design meet structural rigidity requirements? How does it withstand long-term outdoor sealing performance? Dr. Jiang Chengyin: Originally, double-glass modules had no frames. With encapsulation of double-sided strengthened glass fully meeting the module's strength requirements. Adding frame designs primarily protected glass edges from damage. Since the distance from the internal cell's conductive part to the module edge is generally over 15 mm, the waterproof sealing insulation width at the edge is also 15 mm, ensuring long-term outdoor sealing. DAH Solar's design eliminates the front frame but retains side and back frames, bonded with high-strength silicone rubber, maintaining glass edge protection. Silicone rubber offers proven durability and weather resistance. What improvements does DAH Solar's Full-Screen product at this SNEC exhibit offer compared to previous models? Dr. Jiang Chengyin: Our Full-Screen product has advanced to version 3.0, which is a significant improvement over versions 1.0 and 2.0. First, we have adopted the Full-Screen plus “Dense Busbar” (DBB), which is a design similar to 0BB. DBB technology has several advantages, notably significantly reducing silver consumption during cell production, lowering product costs. Additionally, in module production, we've abandoned high-temperature welding processes, using low-temperature film to bond ribbons to cell surfaces. This low-temperature encapsulation process enhances module power, reduces virtual welding and the likelihood of fractures, improves yield, and extends product life by avoiding flux residues that corrode grid lines. Overall, version 3.0 products show significant improvements in reliability and power generation compared to past versions. Furthermore, we now use industry-leading rectangular silicon wafers based on 182 mm as the substrate for TOPCon ce...

How does PV Innovative Benchmarking Enterprise Differentiate In The Game Of SNEC?
The world’s most significant solar energy trade show, the SNEC PV Power 2023, was held on 24th-26th May, in Shanghai, China. DAH Solar as one of the fastest-growing PV companies has fully armed with innovative products and has the confidence to stand out among all the competition. For this important grand meeting, DAH Solar prepared the leading technology products and academic technology sessions to have better interaction with global visitors.
New Upgrade Of Full-Screen PV Module 2.0 Has Been Unveiled
The global patent product, Full-Screen PV Module is not a stranger to global PV market. After one year, it was announced, Full-Screen PV Module has gained a great reputation and recognition around the world, due to its 6-15% power generation growth ability. DAH Solar R&D team spent over 2 years developing Full-Screen module technology.It has even been calledan artwork.
This year, and now, at this SNEC 2023 exhibition,with the leading N-type TOPCon Solar cell technology, the New upgrade of Full-Screen PV Module 2.0 was ready to meet everyone. Currently, the most powerful solar cell technology plus the leading TOPCon technology, the Full-Screen PV Module has accomplished a successful upgrade. Due to its powerful performances, TÜV NORD came to DAH Solar Full-Screen PV Module 2.0 product launch ceremony and showcased the Full-Screen PV Module field test report, then awarded the honor certification.
According to Mr. Chengyin Jiang, the Director of R&D in DAH Solar, “The purpose for us to upgrade the Full-Screen PV Module is to create more energy value for global solar energy users. A truly great innovation is consistent. We value the market’s reviews and feedback. We keep tracking all the feedback from our customers and that’s why we decided to apply the leading TOPCon solar cell technology and upgrade the Full-Screen PV Module. We believe the Full-Screen PV Module will once again surprise the solar energy users.”
The World’s First Integrated PV System- SolarUnit, Newly Upgraded Balcony PV Scene
DAH Solar showed its sincerity and update the world’s first integrated PV system, the SolarUnit. It is worth noting that this year, except for the rooftop usage scenario, the use of balcony PV scenario was specially added.
The SolarUnit copped with the Full-Screen PV Module 2.0 has surprised many visitors. SolarUnit is an exclusive innovation that DAH Solar has achieved. It focuses on solving the sore points in the residential PV market. All plug-in connections make the installation much easier. As the topic of balcony PV systems has risen in the discussion, this time at DAH Solar’s booth, they creatively conducted a stimulating balcony application. The eye-catching and vivid design won large attention during the trade show. The SolarUnit newly added balcony PV system assists in the acceleration of renewable energy in households.
DAH Solar's Topcon Intellectual Manufacturing Strength, And New Upgrade of The Full Range of Product Applications
TÜV Rheinland attended DAH Solar’s TOPCon technology session and awarded the honor certificate for DAH Solar TOPCon high efficient PV module based on the module power generation field test.
DAH Solar leads the N-TOPCon empowerment of the PV decreasing costs and increasing benefits. DAH Solar concentrates on technology creation and is well known for its innovative products like Full-Screen PV Module and SolarUnit. Mr. Xiang Li the Director of the Technology Department in DAH Solar indicates the leading TOPCon solar cell that DAH Solarself-manufactured. Mr. Li demonstrated the basic logic of TOPCon technology academically. This technology session was very professional. Since DAH Solar wanted to reveal the mystery mask of the leading TOPCon technology. During this session, Mr. Li spread the information that DAH Solar’s TOPCon solar cells and PV Modules has been put into the mass production process. Besides, DAH Solar will achieve 5.5 GW TOPCon solar cell production capacity and 5GW module production capacity in 2023. The visitors and global energy users are expecting DAH Solar’s TOPCon modules.
DAH Solar has won outstanding accomplishments during the SNEC PV Power 2023. Mr. William Xie, the President of DAH Solar said, “DAH Solar is an innovation-driven and technology-leading PV company. We focus on solving the industry's sore points through technology innovation.
