DAH Solar makes its debut in the US. RE+2024 ended perfectly! From 10th to 12th September, the three-day largest clean energy event USA RE+2024 was successfully concluded at the Anaheim Convention Center in California. During the exhibition, DAH Solar's global patented product TOPCon Full-Screen PV module debuts in the U.S. market. This exhibition is DAH Solar's debut in the U.S. and attracted many professionals to visit. With the global development of renewable energy, the United States, as the world's second-largest PV market, the demand for installed solar energy is climbing year by year. The total installed capacity of small-scale PV systems installed in the U.S. in 2023 is close to 11.6GW, also a new record. The total installed capacity of PV systems installed in the U.S. in 2023 is 35.3GW, which is 52% higher compared to less than 24GW in 2022. According to Wood Mackenzie and SEIA forecasts, 2024-2029, the U.S. PV's new installed capacity will be more than 250GW, with a compound annual growth rate of about 3%, showing huge market growth potential. During the exhibition, DAH Solar made a stunning debut with its signature product Full-Screen module. As a globally patented product, Full-Screen modules were officially mass-produced in October 2021 and mass-distributed to the global market. Compared with regular PV modules, Full-Screen PV modules have no frame on the front side, so they can achieve no accumulation of water and dust at the bottom and increase power generation by 6%-15%. DAH Solar's technological innovation strength has been highly evaluated by the industry, and the craze of Full-Screen PV modules has been set off in major exhibitions around the world. As the global demand for PV continues to increase in recent years, DAH Solar continues to strengthen its technological R&D and innovation and insists on supplying high-efficiency and reliable modules to the global market. Up to now, DAH Solar products have been exported to more than 100 countries around the world, covering Asia-Pacific, Europe, Latin America, and other regions, and have formed a marketing network to serve global customers. In the future, DAH Solar will continue to increase the pace of global market expansion, actively establish contact and cooperation with all parties to bring DAH Solar high-quality products to the world and work with global partners to promote low-carbon development.

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. The Full-Screen PV Modules are used in a wide variety of commercial and household roof PV power stations and BIPV projects. The Full-Screen PV Module won the TÜV Nord Outdoor Field Performance Award.
