From Full Cells to Half-Cut Cells
II/2
• Increasing module efficiency/higher watt classes and larger cells result in
higher currents also within the module itself
• Resistive losses lead to heating and power loss
• Half-cut cells: 75% lower losses within cell interconnects
Power loss (Heat) = Resistance x Current2

From Full Cells to Half-Cut Cells
• Half-cut cells clearly change the visual appearance of the module and
require a new module design
• Half-cut cell modules consist of 2 halves connected in parallel, hence the
current is split in 2 paths within the module
• Electrical parameters are identical to full-cell modules, thus no changes
for the system design needed

• 6 internal cell strings with 20 half-cut cells each
• Respectively 1 cell string of the upper and lower half are connected to one bypass diode
• The split junction box transfers less heat to the cells lying underneath
• Higher yields in specificshading situations

Example of a typical shading situation(modules installed in portrait mode)
• If the modules are installedin portrait mode, the half-cut cell module can achieve up to 50% more energy yield

to the rails requires an alternative approach during installation
