Half Cell PV Modules. What does it mean?
Half Cell module consists of conventional polycrystalline silicon cells cut in half.
So 60-cells standard PV module becomes 120-cells half-cell PV module.
Why Do We Cut the Cells?
Shorter Bus Bars
he shorter conductor, the less amperage, the lower resistance. Lower resistance reduces power loss up to 6% and increase the output power from 5W to 8W.
More Strings
Instead of 6 strings of cells in conventional 60-cells module, half-cell module includes 12 strings. Instead of 6 strings of cells in conventional 60-cells module, half-cell module includes 12 strings. It deals with the performance mismatch happened between cells caused by shading, cells’ initial heterogeneity and uneven degradation.
Standard module With 6 internal strings of cells
Module current output is 8.7A, current mismatch in series is 0.3A (9,7W)
Half-cell module With 2×6 internal strings of cells
Module current output is 4.5+4.35=8.75A, current mismatch in series is 0.15A (4,85W)
Smaller Cells
The twice smaller cells generate smaller currents that help reduce “Cell To Module” loss. Smaller cell also means twice less damage from micro-cracks in the cell and stains on the glass for the hole module.
Performance & Efficiency
Efficiency upto 18.8%
Efficiency 16.5%
Overheating
Cell’s operating current 4.66A
16.5% lower risk of hot-spots due to lower temperature in partially shaded cells
Cell’s operating current 9.5A
Higher risk of hot-spots in partially shaded cellsх
How does it improve our modules?
Compared to standard PV modules our new half-cell modules are more efficient, have higher performance and less prone to overheating. They better cope with partial shading and are less vulnerable to point mechanical damage and dirt.
