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!

The World’s First Integrated PV System
SolarUnit


SolarUnit is the world’s first integrated PV system, which is independently innovated by DAH Solar. This unique product brings together the advantages of high-tech microinverters and the benefits of the Full-Screen PV Module which is a global patented product that could increase power generation by 6-15%.


The Full-Screen PV Module and microinverter are integrated when it leaves the factory. When customers receive the SolarUnit, the microinverter and the Full-Screen PV Module are attached together. It is an easy-to-install product that combines simplicity and safety by avoiding the use of large quantities of cables and connectors for connecting the PV modules. Since SolarUnit applies the plug-in connection.


In practice, the SolarUnit is like a PV module with an alternating current output, ready to be connected to the electrical grid. The bus is formed by a trunk cable supplied by DAH Solar. The trunk cable has spaced tap connectors to allow sequential connection and electrical parallelism of multiple SolarUnits.


This type of solar solution, with PV modules integrated with microinverters, allows for great flexibility in the design of PV systems, especially for residential usage. SolarUnit could achieve great flexibility for projects because it makes the possibility to install PV modules in different orientations and with different angles of inclination, following the designs of the roofs.

Another advantage, in addition to the ease and flexibility of installing the SolarUnit, is its power generation increase ratio. Each SolarUnit has its own MPPT system (maximum power point tracking), which eliminates the problem of partial shading caused power loss that occurs in traditional strings of the PV modules.



As if the advantages of the integrated design were not enough, the SolarUnit also features state-of-the-art features, using the Full-Screen technology and 1/3 cut cells.The Full-Screen technology consists of manufacturing the module with the front A-side frameless design. It makes the rainfall run over the front surface of the module and prevents the accumulation of dust at the bottom of the modules. The Full-Screen technology could increase power generation by 6-15%.


As for the 1/3 cut solar cell technology, this is a technological innovation that, instead of large half-cells, uses cells fragmented into three parts. The use of tripartite cells gives flexibility in sizing the product and makes it possible to increase efficiency. Due to the smaller area cells provide lower electric current. Lower electric current could reduce the temperature and accomplish higher power generation.


DAH Solar also offers an ECU unit (energy communication unit), which communicates with the microinverters through the PLC (power line communication) system. It uses the power cable itself to exchange information.

The ECU unit allows remote monitoring of the PV system, in addition to allowing the PV system to be turned off with remote control by your electrical devices (smartphone, PC, or pad.)
