Both products rely on the innovative technical processes, the excellent power generation gain and practical value have been unanimously recognized by the industry experts, as well as the high praise of  many professional media chanel in PV industry. What is Full-Screen PV Module There is no frame on the front of the Full-Screen PV Module, but a whole piece of glass. The side uses a Curved Surface 128° R Angle with Prefect tactile, which not only has a good anti-collision effect on the modules, but also has a more beautiful appearance and a better handling feel,Optimized Delivery and Installation Experience.A simple understanding of the full-screen module is similar to the full-screen mobile phone we use, which can be seen at a glance by comparing the photos below. What are the core advantages of Full-Screen PV Module compared to Normal PV Module? No water, No dirt left on the Surface, Full Screen PV Module is capable to decrease power generation loss.The modules are operated outdoors all year round. Due to the height difference between the frame and the glass, the rainwater cannot be drained out of the normal modules. In rainy and snowy weather, or in areas with heavy dust, the modules are prone to water and dust accumulation, especially at the bottom of the module, which affects the power generation of the entire module. For full-screen module there is no height difference between the frame and the glass, No water No dirt left on the Surface and it Design Strong Self-cleaning Ability, Effectively reduce power generation loss, as well as manual cleaning frequency and operation and maintenance costs. How much does water and dirt affect the power generation of normal modules? The average power generation loss is over 6%. Research by professional institutions has shown that among the various factors that affect power generation, module dirt and shadowing account for 25%, which is also confirmed by outdoor filed comparison experiment between full-screen and normal modules. The test data of past year shows that, without manual cleaning and only natural washing by rain, the average power generation of the 182 full-screen module with the same battery and version is 6.15% higher than that of the 182 normal module.，in some days even higher than 9.62%. With time, due to the continuous accumulation of dust, the difference in power generation between the full screen and the normal modules will gradually increase. The front of the module is all glass, how reliable is it? No difference from normal modules. The full-screen PV modules adopts a unique and innovative structural design to make it have the same reliability as normal modules. This is also one of the core technologies of the full-screen PV module patent. Acc...

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...
