Sustainable Innovation: Full-Screen DBB PV Module Started Mass Production

Sustainable Innovation: Full-Screen DBB PV Module Started Mass Production On 15th, May, DAH Solar announced that the Full-Screen DBB (no-bus bar) PV Module has officially started mass production, which takes half a year from design to mass production. Compared with original PV module, the Full-Screen DBB PV Module has the feature of higher efficiency and higher performance, to meet the market demand for high-performance photovoltaic modules. The product shows the ability of DAH Solar in technological innovation and industrial upgrading. The Full-Screen DBB PV Module successfully superimposed DBB technology and patented Full-Screen frameless design. The DBB technology does not have the bus bar at the position of solar cell,which can effectively improve the light receiving area. The use of smaller and more ribbons and directly connected to the fingers, which can easier to collect current and effectively reduce the power generation loss after hidden crack happened. At the same time,the original version of the Full-Screen PV Module with front frameless design can effectively increase the power generation by 6-15%. The advanced Full-Screen DBB PV Module has no bus bar and no white solder joint, the PV Module looks more tidy. The combination punch brings the PV Module performance to a higher level. DAH Solar, The Founder & Master of Frameless PV Module!

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.

TOPCon manufactory base


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.
