Just as bifacial solar panels and PERC solar cells provide small boosts in the efficiencies of silicon solar panels, implementing half-cut cells in solar panels can help improve the power output of a solar panel system.
Module efficiency leading in industry, up to 20.4%
Passed 3*IEC standard test
1/2 current, reducing the hot spot temperature
As low as 43℃, improving the power generation efficiency
The benefits of Half Cut Cells
The modules assembled with half cells not only generate more power output, but also perform better during daily operation as a result of lower temperature coefficient of power, along with reduced shading effect on the energy generation, lower risk of hot spot, and enhanced tolerance for mechanical loading.
1. Lower resistive losses. A half-cut cell carries half the current and a quarter of the resistance of a full cell. So a complete half-cell module has the same current but half the resistance of a regular module. Resistance = wasted power, meaning a half cell solar panel can boost output by around 3%.
2. Durability. Since the cells are physically smaller, they are more averse to cracking.
3. Shade resistance. A regular panel is made up of 3 rows of cells connected in series with bypass diodes. If one cell is shaded, a third of the panel’s output can be lost. But in a half-cut panel, there are 6 rows of cells. So, if one of the cells is shaded, only a sixth of the output is lost.
4. Less chance of hotspots. With a lower current in each cell, there’s less heat concentration.
5. Reduced installation area. Roof space can be saved using half cell technology.
