DAH Solar Module Manufacturing has been Comprehensively Upgraded At the beginning of 2023, DAH Solar completed the module production factory upgrade. As an innovation-driven and technology-leading solar manufacturing company. DAH Solar always focuses on improving manufacturing efficiency and quality control through production technology improvement. Currently, DAH Solar has upgraded its production process by bringing in high tech talents and advanced equipment. DAH Solar optimized serval production processes, like EVA positioning control, welding, automatic inspection, and water cooling. The result of this investment is very surprising. DAH Solar has achieved a new production speed that producing one module only takes 16 seconds instead of 22 seconds! For EVA positioning control, this process is to settle the EVA on the module for bonding the solar cells and the back sheet. This improvement could make sure the overall overage so the EVA sheet won’t shift in the later process. Besides, the welding procedure improvement is very significant. DAH Solar changed the old welding method. Now the welding is through heating the bus bar instead of directly heating the solder strip. For the TOPCon module, the solder strip is even thinner. If directly heating the strip, it has greater odds of causing the solder strip breakage. Heating from the bottom of the bus bar could perfectly solve the problem because the bus bar could balance the heat conduction. Also, the water cooling machine could help the module decrease the temperature after the EVA melting process. As we all know, after the EVA melting procedure, the module could reach to 140℃. Without the cooling system, it needs to take a longer time to reach the next step of operational temperature. Before it gets cool down, lifting the module could deform the glass and the solar cell, in some extreme cases, the glass would even be broken. DAH Solar introduce an advanced cooling system, which will shorten the cooling time and decrease the temperature to 25℃. This will help increase the production efficiency. During this visit, a direct phenomenon could be observed, which is the number of workers has decreased. The production manager Mr. Wang claimed that the DAH Solar module factory has accomplished fully automatic production, which means the production is getting more and more accurate and the requirement of workers are more strict. Mr. Wang said DAH Solar has upgraded all the inspection equipment. In the past, some inspections relied on visual inspection but now it changed to autoscan and the program will automatically check the quality. All in all, DAH Solar upgraded its production line to a more preciously, more efficient, and fully automatic. With those improvements, DAH Solar could achieve an annual module production capacity of 7GW+. More and more automatic equipment significantly increased production efficiency and better control of production details. DAH Solar commits to delivering high-quality solar ...

DAH Solar Continues To Create MiraclesWithin only 23 days, DAH Solar set a new record for the efficiency and yield production speed of the TOPCon solar cell production line. DAH Solar's TOPCon PE-poly production line (SE not included) achieved an average mass-production conversion efficiency of more than 25.4%, and the solar cell yield rate exceeded 97%, which is the leading record in the PV industry. This is also the fastest TOPCon production line to reach this indicator in history. DAH Solar has set a new record in the industry. DAH Solar, as a global technology-leading PV company, steps into TOPCon solar cell manufacturing for the first time and achieved such success, which fully reflects the professional level and execution efficiency of DAH Solar's TOPCon solar cell team. At the same time, it fully demonstrates that DAH Solar has always adhered to technology innovative development strategy and the long-term technological accumulation has once again interpreted the " speed of DAH Solar".

DAH Solar Plans To Build 7GW TOPCon Silicon Wafer Solar Cell Manufacturing Base in Shanxi On the morning of June 3, DAH Solar Co., Ltd., Jinzhong Development Zone Management Committee of Shanxi Transformation Comprehensive Reform Demonstration Zone, and China Three Gorges Corporation Shanxi Branch discussed the " DAH Solar 7GW high-efficiency N-type silicon wafer and solar cell production base project" reached the strategic cooperation and formally signed a contract. The project plans to build 7GW of high-efficiency N-type silicon wafers and 7GW of high-efficiency N-type solar cell production capacity, with a total investment of about 2 billion Yuan RMB. Before the signing ceremony, project-related leaders visited and inspected DAH Solar’s headquarters base and DAH Solar’s TOPCon Manufacturing base. To have the meeting with Xie Shenheng the President of DAH Solar and Bian Chonglei, the CEO of DAH Solar Waiting for the leaders to hold a discussion on this strategic cooperation. Xie Shenheng, the President of DAH Solar, indicated that DAH Solar's 7GW high-efficiency N-type silicon wafer and solar cell production base project is important for the company to deepen its industrial integration layout. The strategic cooperation between DAH Solar, Jinzhong Development Zone, and Three Gorges Group will further consolidate the company's strategic development foundation in the next five years, which improve the company's integrated industrial layout, and enhance the company's comprehensive competitiveness. The three parties will give full effort to their respective advantages, strengthen in-depth cooperation at the levels of industry, technology, and market, promote the high-quality development of the regional economy, jointly help the photovoltaic industry reduce costs and increase efficiency, and contribute to the achievement of the goal of carbon dioxide emission and carbon neutrality.

DAH Solar Support Brazilian Solar Business Development     On 28th Nov. 2022, our close friend Canal Solar, which is the largest PV media in Brazil, was holding the conference Canal Conect. This event is to bring together professionals within the PV market for interaction and exchange of ideas about the sector. Besides, it could promote networking and interaction to expand professional relationships for businessmen and businesswomen within PV sector. This event presents discussion and case studies for reference in this fast-growing industry.     DAH Solar was the first invited to this solar congress. Because we are ranking as top 3 PV module manufacture in Brazil. We value the Brazilian market. After we get the invitation, we decided to participate and help our friend with their event flawlessly.     We always know that Brazilian market values cost-efficient products. That’s why our global product Full-Screen PV Modules are so popular in Brazil. Based on Brazilian PV market, we will newly launch the world’s first integrated PV system, SolarUnit.     This product is focused on residential solar solutions. The Full-Screen PV Modules and the microinverter are integrated into one complete solar system. This product’s efficiency is as high as 97.57%. SolarUnit will definitely melt into Brazilian market, due to the specific application proportion in the Brazilian PV market, 60% of the application is residential.     DAH Solar always put users’ desire at the top. We contribute to creating more value for our customers. We make sure efficient solar energy more convenient.
