Sharp has added a new all black design monocrystalline silicon photovoltaic (PV) panel to its half-cut cell portfolio.

Dubbed the NU-JC320B, the half-cut cell PERC module offers a two to three percent higher module performance compared to standard full cell panels, providing design-oriented customers with an efficient and reliable solution for residential and commercial installations, Sharp claimed.

The NU-JC320B delivers a power output of 320W with 120 monocrystalline half-cells and Sharp’s positive power tolerance of up to five percent which makes it pretty useful for installers. The module has a black frame and back sheet for style conscious commercial customers and homeowners.

The new panel features Sharp’s half-cut cell technology – full cells are cut into two equal parts, which means the electrical current generated per cell is halved and resistance losses are reduced to one quarter, ultimately increasing the power output for the user.

The halved current produced in the modules significantly decreases the temperature in the cells, reducing the risk of hot spots and increasing the lifespan of the module. The half-cells also have three small junction boxes instead of one, each fitted with a single bypass diode, which transfers less heat to the cells above and boosts the longevity of the panels, improving the overall performance of the system.

The new module can be mounted in portrait, which is beneficial for shaded conditions such as tilt-mounted roof installations, as unlike full cells, the half-cut cells can still generate a 50 per cent performance with the upper half of the module, even when the lower half is shaded.
