NU-JD440 Sharp PV panel
The NU-JD440 has a module efficiency of 19.9% and uses 144 M6 wafer size half cells
Sharp last month announced the addition of a new 440W monocrystalline silicon photovoltaic (PV) panel to its half-cut cell portfolio.
The NU-JD440 has a module efficiency of 19.9% and uses 144 M6 wafer size half cells. This decreases the balance-of-system costs per watt-peak installed across the whole BOS component range, providing customers with lower levelized costs of electricity (LCOE) and a higher return on investment.
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.
A low temperature coefficient of -0.347%/°C for the power output ensures higher performance at high environmental temperature, which becomes increasingly important due to climate change and the resulting rise in temperatures.
In addition, the NU-JD440 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.
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 has been recognised with IEC seals (IEC61215 and IEC61730).
Hitachi ABB Power Grids is delighted to launch the TXpertTM Ecosystem for digitalisation of transformers.
The ecosystem is designed to drive datadriven intelligence and decision making in the operations and maintenance of transformers and power grids. It is a complete suite of products, software, services and solutions that work together and have the capability to integrate with new and existing digital equipment from other manufacturers.
The TXpertTM Ecosystem provides options to mitigate all of these. For example, failure of bushings can lead to transformer tank rupture and explosions, resulting in millions of dollars in repairs and settlement costs for a utility, while the cost of replacing a high-voltage bushing would be a few percentage points of this3).
Using TXpertTM Ecosystem solutions for digital asset management of bushings, the real-time status of the bushing health can be monitored and corrective action taken before failure probability becomes high. At the heart of the ecosystem is the TXpertTM Hub from Hitachi ABB Power Grids – a data monitoring and diagnostics device that also provides connectivity.
Designed as an open platform, it is capable of integrating multiple sets of data from TXpertTM Ready sensors from diverse manufacturers, simplifying the digitalization of transformers in compliance with modern communication and stringent cybersecurity standards.
Data and intelligence from the TXpertTM Hub can be accessed locally and if required from cloud-based solutions.
TXpertTM Enabled transformers can be augmented with Asset Performance Management (APM) solutions from Hitachi ABB Power Grids. As an enterprise level software solution, the APM can be used for individual, multiple or large fleets of transformers.
Supporting customers putting the data generated from TXpertTM for smart decision making, associated remote and advanced services can provide virtual site management, life assessments, robotic inspections and transformer care service agreements. Customers can flexibly deploy the ecosystem in new transformers or in transformers of their existing fleet from Hitachi ABB Power Grids and other manufacturers, with customized TXpertTM solutions as per their specific requirements.
