Monocrystalline panels have a high power output, occupy less space, and last the longest. Of course, that also means they are the most expensive of the bunch. Another advantage to consider is that they tend to be less affected by high temperatures compared to polycrystalline panels.
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
Half-cut solar cells are exactly what their name suggests – they are traditional silicon solar cells that have been cut in half using a laser cutter.
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.
