Sharp launches 445W half-cut cell PV panel

The NU-JD445 has a module efficiency of 20.1 per cent and is suitable for a voltage up to 1,500 V, using 144 M6 wafer size half-cells. This offers the best balance between cost reductions and system compatibility. A low-temperature coefficient of -0.347%/°C for the power output ensures good performance at a high environmental temperature, which becomes increasingly important due to climate change and the resulting rise in temperatures.

The NU-JD445 is 2,108x1,048mm, including an optimised frame with a weight of only 25kg, making it easy to set up and deploy. In addition, the NU-JD445 module uses 1,670mm cables which enable trouble-free wiring in landscape installations and also allows for leapfrog wiring when installing in portrait, helping to further reduce system costs.

Andrew Lee, Sales Director EMEA, Sharp Energy Solutions Europe said, "We are pleased to expand our half-cut cell portfolio with a higher wattage size mono half-cell module of 445W, specifically designed for free-field and commercial/industrial rooftop installations. With our team based in Germany and services offered across Europe, Africa and the Middle East, our customers can always count on maximised product and service value."

The new module features 9 BB (multi busbar) technology using round ribbons which increases the power gain from each cell and making them less sensitive to microcracks, offering higher module reliability. 

All Sharp half-cell modules have three small junction boxes instead of just one, each fitted with one bypass diode. These junction boxes are transferring less heat to the cells above and in turn, boost the longevity of the panels and the overall performance of the system.

The safety, quality and durability of the panel have been recognised with IEC seals (IEC61215 and IEC61730). The modules have been rigorously tested for compliance with international standards and for endurance under extreme conditions, passing tests for ammonia, salt mist, sand and PID resistance.
