Hamburg, 25th October 2022 – Sharp today announces a five-watt upgrade for three of its half-cell panels, the NU-JC415, NB-JD545 and NU-JD545.
New – the NB-JD545
The new NB-JD545 is the upgrade to the NB-JD540 and is a bifacial half-cut cell monocrystalline silicon photovoltaic (PV) panel, designed for commercial and utility scale free-field installations. It has a module efficiency of 21.1%, a low temperature coefficient of -0.349%/°C and is equipped with 144 M10 wafer-sized half-cells.
The module is designed for a system voltage up to 1,500 V and is printed with white reflectors in the gaps between the cells on the rear glass to increase light absorption on the front side. A high-performance encapsulation foil with a combination of EVA (ethylene vinyl acetate) and PEO (polyolefins) is used to prevent potential-induced degradation (PID) affecting the rear side of bifacial modules.
The dimensions are 2,278 x 1,134 mm, with a 30 mm aluminium frame. The front and back glass layers are each 2 mm thick, and the panel weighs 32.5 kg in total.
The module is covered by a 30-year linear guarantee on the nominal power output and a 15-year product guarantee for EU Member States and various other countries. The guarantee starts on delivery of the panel to the final customer.
New – the NU-JD545
The NU-JD545, the upgrade to the NU-JD540, has a module efficiency of 21.1%, a low temperature coefficient of -0.341%/°C and is designed for a system voltage up to 1,500 V. Like the NU-JD545, it uses 144 M10 wafer-sized half-cells.
The NU-JD545 measures 2,278 x 1,134 mm, including an optimised frame with a weight of just 27.5 kg, making it easy to set up and deploy. In addition, the NU-JD545 module uses 1,750 mm cables which enable easy wiring in landscape installations and allows for leapfrog wiring when installing in portrait mode.
New – the NU-JC415
The NU-JC415, the upgrade to the NU-JC410, comes with 108 half-cells, an anodised silver frame and white backsheet, delivering an efficiency of 21.25% and a low temperature coefficient of -0.341%/°C.
The panel is equipped with the original MC4 connector, which makes it compatible with most mainstream optimisers, inverters and mounting systems. The dimensions of the NU-JC415 are 1,722 x 1,134 mm and it weighs just 20.7 kg, thus meeting the requirements for easy residential and small-scale commercial and industrial (C&I) rooftop system installation. Furthermore, the panels are suitable for clamping on the short frame side.
In the EU Member States and various other countries, the NU-JC415 and the NU-JD545 are covered by Sharp’s 15-year product guarantee and 25-year performance guarantee, promising a minimum 85% performance in year 25. This guarantee starts on delivery of the panel to the final customer.
All modules feature 10 busbar technology using round ribbons to increase the power gain from each cell and make them less sensitive to microcracks, thus improving module reliability.
Furthermore, all three panels have three small junction boxes instead of just one, each fitted with one bypass diode.
The safety, quality and durability of the panels 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.
