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.

Advantages of ON-Grid Solar System-40KW solar power system

1. Become Money with Our  Great Sun

"Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries."

2. Utility Grid as a Virtual Battery

"The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. In other words, more electricity goes to waste with conventional battery systems."

3. Higher Efficiency 

“With power classes up to 270 Wp and up to 16.5% efficiency it’s the most powerful 60-cell standard module on the market, ideally suited for obtaining maximum yield from smaller rooftop areas.”
