These cells are usually Crystalline Silicon cells with high energy conversion efficiency rate. This means that the cells, formed into panels, can generate more power even though the panels are just large enough to fit into limited spaces such as rooftops, making them space-efficient and in the long run, cost-efficient.
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 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.
