Vertex 19R series, features the latest 210R rectangular silicon wafer technology to boost single-module power by up to 30W. It comes in horizontal packing and is compatible with most inverter models in the market and able to achieve higher DC/AC ratio at system level, making it an ideal choice for commercial and industrial rooftop projects. The module has maximum power output up to 580W and maximum efficiency of 21.5%. It uses 210mm cells and is different to the earlier generation DE19 module, because it incorporates rectangle rather than square-shaped solar cells.
