26.5%! A New Record of Mass Production Conversion Efficiency of TOPCon PV Modules by DAH Solar DAH Solar recently announced that the average mass production conversion efficiency of its TOPCon PV Modules has exceeded 26.5%, which sets a new record and continues to maintain the industry-leading level. Compared to the theoretical limit of 28.7% efficiency, breaking through 26% surely means a lot. The LECO laser-enhanced contact optimization technology was used to separate the two key steps of metal erosion and contact formation considering its high  concentration of energy and controllability during the high-temperature sintering process, in this way the sintering process can be more precisely controlled. The full integration of the LECO equipment was completed within 7 days, which not only improved efficiency but also effectively reduced the difficulty of Poly back, showing important significance for the long-term competitiveness of TOPCon PV Modules. DAH Solar TOPCon base completes construction to operation in six months, achieving ramp up production in 23 days, reaching an industry-leading level in three months, and setting a new record for mass production conversion efficiency within 6 months. As a benchmark enterprise for differentiated competition in the photovoltaic industry, DAH Solar's continuous breakthroughs and iterations in the key technology fields of the industry highlight the company's innovative strength and perseverance to industry leadership, providing a strong driving force for promoting industrial upgrading and sustainable development.

8.09% More Power Generation！DAHSolar Full-Screen PV Module Report of XuanCheng 1.04MW Power Station Power Generation Report from the first three quarters of 2023 for the 1.04MW Full-Screen module photovoltaic power station constructed by Anhui Zhongyi Electric Power Environmental Protection Equipment Co., Ltd. (referred to as Zhongyi Electric Power) Park located in Langxi Economic Development Zone, Xuancheng City, Anhui Province was released. The average power generation gain per watt of the Full-Screen module is 8.09% higher than that of Regular modules! Project Overview The project is located in Xuancheng City, Anhui Province, in a mid latitude region, with a subtropical humid monsoon climate and distinct seasons. The average annual power generation is about 1020 hours (the smaller the inclination angle of the photovoltaic power station installation, the shorter the available sunpower hours), and the average annual temperature is 15.6 ° C. It belongs to the category III development area of solar energy resources, and the development value of solar energy resources is good. Project Design The 1st phase of the project is connected to the grid with a capacity of 1.04MW, using a total of 1932 photovoltaic modules, using DAH Solar Full-Screen modules(540W, 182mm/72 pieces), as well as regular modules (same 540W, 182mm/72 pieces). The inverter uses Sungrow 100kW series inverter, with a total of 9 units. The project sets up distribution cabinets according to the grid connection points, with 10kV outgoing lines. The components are laid flat on the colored steel tiles of the factory building using crossbeam guide rails, and the installation angle is 5 °. The full screen component is installed in the same way as the regular component, using fixtures to fix it and equipped with EPDM gaskets to prevent scratching the front glass of the component when installing the pressure block. The power station was integrated into the power grid on September 27, 2022. Power Generation Results In the first three quarters of 2023, the cumulative power generation of the power station was 890896.1kWh, of which the Full-Screen PV Module power generation was 512188.1kWh, and the average daily equivalent hours were 3.22h; The power generation of Regular Module is 378708kWh, and the average daily equivalent hours are 3.02h. At present, all operational indicators of the power station meet the empirical requirements. This is due to the fact that the Full-Screen PV Modules do not accumulate water or dust, resulting in better power generation performance. The data from the report shows that the average power generation gain of Full-Screen PV Module reaches 8.09%. The front-side of DAH Solar Full-Screen PV Modules has frameless design, greatly improving the drainage and sewage capacity of the modules, and reducing the power generation loss caused by dust accumulation and obstruction. At the same time, without manual cleaning, the Full-Screen PV Modules are still very clea...

DAH Solar Amazed the 2023 Solar Solutions Düsseldorf with Innovative Products The 2023 Solar Solutions Düsseldorf was held on Nov.29th in Düsseldorf, Germany.

Solar & Storage LIVE Witnesses “Full-Screen” Stunning Showof DAH Solar "Full-Screen" has become a unique label for DAH Solar. As the globally patented product, the Full-Screen module was first released at SNEC in 2021 and went into mass production and large-scale shipments in October of the same year to domestic and foreign markets,its market influence and reputation have rapidly increased due to its function of "Self-Cleaning",  which brings a power generation increase of 6-15%. The shipment volume has continued to grow rapidly, and the company's technology innovation strength has been highly praised by the industry, setting off a trend of Full-Screen modules at major exhibitions worldwide. From October 17th to 19th, Solar & Storage LIVE (referred to as "UK Exhibition"), the largest renewable energy and ESS exhibition in the UK, was successfully held in Birmingham. DAH Solar showcased its globally exclusive patented product —— Full-Screen Module 2.0 series, providing stable and efficient differentiated solutions for distributed photovoltaics worldwide. This attracted numerous industry experts who visited for information exchanges. The UK is one of the European important GW-level photovoltaic markets. As of the end of July this year, the cumulative photovoltaic power generation capacity in the UK reached approximately 1.53GW with an additional installed capacity of 643MW. Currently, over one million British households have installed rooftop solar modules, while commercial buildings such as schools, warehouses, parking lots, waters, etc., hold great potential for development in distributed scenarios. The Full-Screen Module 2.0 series, (TOPCon Full-Screen Series Modules) showcased at this exhibition, perfectly combines Full-Screen patent technology with DAH Solar's self-developed TOPCon cells – resulting in higher power output efficiency with lower degradation rates compared to previous versions, significantly improving performance levels. The front no-frame design of the Full-Screen module solves the problem of power generation loss caused by water and dust accumulations that have plagued distributed photovoltaic power stations for many years. Especially in the scenarios where the installation tilt angle is small, where dust accumulates, or where maintenance and cleaning are difficult to achieve, the advantage of power generation gain is more obvious.Empirical data fromTüVoutdoor shows that power generation gains can reach 6-15%. At present, the total installed capacity of the Full-Screen Module photovoltaic power station has exceeded 8,000 globally, and the power generation gain from customers has far exceeded expectations.As the pioneer of Full-screen technology, DAH Solar always adheres to technology innovation to continuously drive high-quality development and help global partners and customers achieve energy transformation.
