DAH Solar Start the Full-Screen Era with New Products at SNEC2024

DAH Solar Start the Full-Screen Era with New Products at SNEC2024   On June 13rd -15th, DAH Solar took part in the 17th(2024) SNEC at the China National Convention and Exhibition Center. The new products of DAH Solar’s Full-Screen series and the all scene application solutions made an impressive debut at the exhibition. The demonstrated innovative technology breakthroughs become another unalterable consolidation of DAH Solar’s position being a photovoltaic innovation leader. Being the founder and master of frameless module, DAH Solar is always seeking for the development and new possibilities of Full-Screen PV module. Currently the newly upgraded Full-Screen technology shows excellent compatibility by achieving superposition perfectly with all mainstream photovoltaic technologies. DAH Solar Full-Screen Rectangular Double-Glass PV module integrated industry-leading global patent Full-Screen technology and breakthrough double glass encapsulation process. The 85% high bifaciality rate brings a 5-25% power generation increase and the Full-Screen no-frame design effectively avoid 6-15% power generation loss due to ash accumulation. The adoption of rectangular cell and TOPCon high-efficiency cell technology greatly reduces the cost of single watt unit and raised the power generation of the module to a new level. The Full-Screen DBB(Dense-Busbar) PV Module eliminates the bus bar of the printed, reduces the shading area, achieves 20%+ silver consumption reduction, increases 0.1%+ conversion efficiency, and increases the average power of the module by more than 3W. The Full-Screen Colored Module and the all black series modules also win the favor of visitors oversea for their aesthetic design and lead the distributed scene aesthetic new fashion. In addition, DAH Solar also brought a number of theme technology sharing events where upstream and downstream industry experts exchanged and discussed the innovative application of advanced technology. Technological innovation is the significant way to drive the development of the photovoltaic industry as well as the core competitiveness of high-quality development of enterprises. DAH Solar regards technological innovation as the source of continuous progress, and will constantly lead the new trend of industry technology, open up unlimited possibilities for photovoltaic, and provide a more efficient and reliable green energy future for global users.

Power Generation Increased by 11.5%! The Full-Screen PV Module Outdoor Field Test Report Published by TüV Nord



TüV Nord published the outdoor field test report for the Full-Screen PV Module. This product is innovated by DAH Solar, and it has a global patent in 18 countries and regions. The report indicated the power generation for the Full-Screen PV Module is increased by 11.5%.


The rooftops with small-angle installation conditions would form the bottom soiling due to the nature rain wash and the altitude intercept between the regular PV module frame and glass. This problem is the primary reason that causes the shade and hotspots on commercial and household PV stations. This bottom soiling could form a “shading belt” with different widths. At some extreme conditions, the “shading belt” could completely cover the PV module, which will decrease the power generation, harm the PV module generation capacity, and shorten the life span of the PV module. The Full-Screen PV Module with frameless front A-side design could let the natural rainfalls wash away the dust. This innovation would avoid the bottom soiling and eliminate the power loss by dust covering.


TüV Nord Outdoor Field Test PV Power Station in Ningxia Province


The Full-Screen PV Module outdoor field test PV power station is located in Xixia District, Ningxia Province (38°36’56.77” N,106°0’52.27” E). The demonstrative test was implemented by TüV Nord, which relies on its testing and demonstration platform. This comparison test applied 182mm Cells Full-Screen PV Module(DHT-M60X10/FS-460W) with frameless front A-side design, which was independently innovated by DAH Solar and the 182mm Cells regular PV module(DHT-M60X10-460W). To control variables, each module contains 6X30 pieces of cell, and the power generation efficiency are both 460W. All the PV modules are 182mm Cells PERC mono-crystal PV modules. The fixed installation angles for both types of modules are 5° (simulate the installation angles of color steel tile rooftop). The comparison groups used the same micro-inverters to achieve the MPPT tracking. These 2 groups could showcase the different power generation performances for 2 types of modules under natural conditions. Before the field test, the 2 groups were exposed to the sunlight 60Wh/m2 and tested the initial power. Then the lab controlled the installation method, ground condition (soil, sand, rock, and grass), and the length of the PV cable.


The front irradiance is 170.28 kWh/m2 in April. DAH Solar produced the Full-Screen PV Module generated 73.21 kWh, and the cumulative power generation per watt is 161.17 Kwh/kW. The regular PV module generated 65.06kWh,and the cumulative power generation per watt is 144.54kWh/kW. Compared to the regular PV module, the Full-Screen PV Module increased the power generation by 11.5%. This field test illustrated the Full-Screen PV Module has advantages in avoiding bottom soiling and reducing dust covering.



Analysis of Power Response Characteristics of PV Modules in Different Temperature Ranges


The power responsiveness data of the 2 modules in each temperature range indicated that in each operating temperature range, the performance of the Full-Screen PV module per watt (performance per watt = average power ÷ measured power) is better than the regular PV Module. As the height increases, the difference in power response characteristics between the Full-Screen PV Module and the regular PV module is proportionally increasing.



Analysis of PV Modules Strong and Weak Light Response Characteristics


In order to research the power generation performance of the 2 types of module under various irradiation values. TÜV NORD compared the power response characteristics of the 2 types of module in each irradiation range. The result showcase that the Full-Screen PV Modules’performance is better than the regular PV modules in each irradiation range. As the irradiation value increases, the difference in power response characteristics between the Full-Screen PV Modules and the regular PV modules also increases proportionally.



The Full-Screen PV Module is innovated by DAH Solar. This product holds a global patent in China, Brazil, Germany, Spain, The United States, Australia, Japan, and other 18 countries and regions. The Full-Screen PV Module obtained high recognition and reputation all over the world, because of its power generation increasing and product reliability.
