This time, DAH Solar brought the global patented product Full-Screen PV Modules to Italy. The Full-Screen PV Modules do not accumulate water, dust, and power generation increased by 6-15% , which attracted many interested customers to stop by, and received unanimous praise. Once again The Full-Screen PV Modules has won great reputation in Europe. According to the Italian ANIE RES website, Italian photovoltaic power generation continued to grow in the first half of 2022, with grid-connected power reaching 1,061MW, an increase of 193% compared to the same period in 2021. According to the framework document drafted by the Italian Ministry of Economic Development and Environment, Italy plans to increase the proportion of renewable energy in total energy consumption to 28% by 2030, of which the proportion of renewable energy in power generation will increase to 55%. Facing the growth of PV installed capacity in European markets, DAH Solar brings more valuable PV products to global users through continuous innovation. With the advantages of beautiful design and power generation increasing, the front frameless design can not only perfectly achieve the effect of no water and dust accumulation, and more power generation, but also perfectly integrate with the building. The product reliability and power generation gain have been well received by global customers. It has been highly recognized that compared with regular modules of the same version, the power generation of Full-Screen PV Modules can increase by 6-15%. In addition, the Full-Screen technology can be applied to all the DAH Solar's modules. We provide users with personalized customization services. With the  "Carbon Neutrality" goal, DAH Solar will make great success on the global stage and create more value of photovoltaic products through our intelligent manufacturing and leading innovation technology. Coming Up Exhibition in Germany -- SOLAR SOLUTIONS DÜSSELDORF Date: 2022.11.30--12.01 Booth: C6

Xuancheng 1.04MW Full-Screen PV Module PV Power Station Power Generation Increased by 8.2% The roof of PV modules basks in the sun, and enterprises enjoy the "sunshine income", and more and more enterprises spontaneously invest in distributed PV power generation. Before the National Day, the 1.04MW Full-Screen PV Module PV power station built in Anhui Zhongyi Electric Power Environmental Protection Equipment Co., Ltd. (Zhongyi Electric Power) which is located in Langxi Economic Development Zone, Xuancheng City, Anhui Province. The PV power station was successfully connected to the grid, which is a milestone for Zhongyi Electric Power, since then, the company will be using "green electricity". This could save industrial electricity expenses for enterprises, and contributes to the balance of social electricity consumption and "Carbon Peaking" and "Carbon Neutrality". Full-Screen PV Module - The First Choice for Small-Angle Rooftop PV Power Stations Zhongyi Power currently has 2 production factories, a comprehensive office building, and its auxiliary storage and transportation projects, covering a total area of nearly 70,000 square meters. The annual electricity bill is about 1.2 million yuan, and the electricity cost remains high. "The 1.04MW Full-Screen PV Module PV power station adopts the 'self-generated and self-consumption surplus power grid' model, which has been fully consumed and can provide about 1.2 million kWh of green and clean power every year. It effectively utilizes the resources on the rooftop and can power its own production activity. This PV power station could save the energy cost of the enterprise. It can serve multiple purposes." The employee in charge of Zhongyi Power said that the global patented Full-Screen PV Module, from DAH Solar, has a beautiful appearance and does not accumulate water or dust, which is especially suitable for steel rooftops with small installation angles. It can effectively reduce the operation and maintenance costs of the power station. The power generation is also greatly improved compared to conventional modules of the same version. Power Generation Data: The Full-Screen PV Module Could Increase Power Generation by Over 8% (compared with regular PV module) In order to allow customers to compare the power generation of Full-Screen PV Modules and regular PV modules in a more accurate and intuitive perspective, the power station design is specially selected in the same version (182mm/72 pieces), the same power (540W), the same number of Full-Screen PV Module and regular PV module, and the same type of inverter (100KW). According to the monitoring data of the power station in October, the Full-Screen PV power station has exceeded more than 70,000 kWh in just 21 days. With the continuous accumulation of dust shading at the bottom of regular PV modules, the differences in power generations between these 2 stations are expected to be even greater. The reason why the Full-Screen PV Module can have such a pow...

Technology Leading & Innovation Driven DAH Solar independently developed Full-Screen PV Modules could increase power generation by 6%-15% (compared to the regular PV modules in the same version). Full-Screen PV Module holds global patent in 18 countries and regions around the world.  There is no frame at the front A-side of the module, which would allow the natural rainfalls to wash away the surface dust, without forming a shading belt at the bottom of the module. Full-Screen PV Modules achieve the benefit of higher power generation because of no dust shading belt at the bottom. After eliminating the front frame, the Full-Screen PV Module could accomplish a better “self-cleaning” feature， and avoid the risk of power loss and hot spot. In addition to the independent research and development of Full-Screen PV Modules, DAH Solar also has innovatively built 1/3 cut Low Current PV Modules to achieve a 3.5% power generation increase (compared to same solar cell in half-cut module version). Besides, the Full-Screen PV Module technology could apply to both half-cut PV Module and 1/3 cut Low Current PV Module.  DAH Solar pursues technological innovation, with an annual R&D investment of 70 million. The technical employees’ proportion is 15% of the entire company. To better serve the market demand and lead advantages in technology research and development, DAH Solar will continue to invest in the R&D Center for micro-inverter, energy storage systems, TOPCon solar cells, TOPCon PV modules, and intelligent manufacturing bases to expand the scale of mass production. We hope to bring more valuable photovoltaic products to global users through continuous innovation. The total investment of the project is about 1 billion, covering a total area of 108 mu. "After the project is fully put into production, it can achieve an annual production of 1 million sets of micro-inverter and energy storage systems, as well as a production capacity of 5.5 GW TOPCon solar cells, and 2GW TOPCon PV module, with an annual output value of 10 billion. DAH Solar not only invents the global patented product Full-Screen PV Modules but also will launch the world's first integrated PV system-SolarUnit. The SolarUnit has the advantages of convenient installation, higher power generation, lower cost, enabling remote monitoring, and rapid shutdown.  With our leading technological innovation and excellent product quality, we enable global users more conveniently and stably to obtain efficient clean solar energy. We have over 200 patented technologies used in our PV products.
