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 ...
