Sharp Solar Panel NU-JC370

Sharp presents its range of high-performance PERC monocrystalline 120 half-cells photovoltaic modules from 320Wp. Thanks to the half-cell technology, the Sharp Solar Panel NU-JC370 has a 2-3% higher performance and higher efficiency than modules of the same size with a whole cell.

The half-cell module is divided into two upper and lower halves, connected in parallel via 3 substrings in series.

The main benefits of the half-cell modules for users are a 2-3% higher module performance and higher total yields. In a half-cell module, standard full cells are cut into two equal halves. In addition, the module is also divided into an upper and a lower half and the half-cells arranged thereon.

By dividing the cells, the power generated per cell is halved and resistance losses on cell and module level are reduced to one quarter. In addition, the halved current can significantly reduce the temperature in the cells and therefore reduce the risk of hot spot effects. The three small junction boxes, each fitted with only one bypass diode, are transferring less heat to the cells below as well.

These factors also boost the longevity of the overall system and dividing the module in half will also have an impact on the overall performance. The path of the generated current is shortened by dividing the module, further reducing resistance losses. Mounting the module vertically will also prove beneficial in shading situations.

Three Junction Boxes

The junction boxes become 3, containing a bypass diode, with this system a better heat dissipation is guaranteed and the module lasts longer over time.

Shorter busbars> lower currents> 75% less losses due to resistance
Lower cell temperatures> increases module longevity
Lower current> lower cell temperature> less risk of hotspots
Up to 15 W more production per module
These factors have the effect of increasing the longevity of the entire system and an impact on overall performance.

Higher Yield Even In Case Of Shading

The half-cell modules thanks to the divided structure, a two-half has a higher efficiency even in the event of shading.

For example, if the lower part of the module is shaded, the module still generates 50% performance with the upper part, while the production of a whole-cell module would be completely compromised.

This could be the case of shadows between the rows in installations on open fields or roofs, in this way we can guarantee production from sunrise to sunset.
