Transparent / Grid Series
Transparent Grid Black/White
HD-CPC-TGW / HD-CPC-TGB
1% to 2% more annual energy yield, over 15% less weight, and no light leakage.
A transparent backsheet lets bifacial light through and lets inter-cell light straight out the back, which is why plain transparent film disappoints on a monofacial module. A white backsheet reflects that light back but blocks the rear entirely.
The grid construction takes both: transparent where the rear needs to see light, a 15 µm reflective grid coating exactly where the gaps between cells are. Published gain is 1% to 2% of annual energy yield, with over 15% weight reduction against conventional solutions.
Why this one
- 1% to 2% increase in annual energy yieldThe grid coating recovers inter-cell light that a plain transparent backsheet loses.
- Over 15% weight reductionCompared with conventional solutions, which in a utility module translates into structure and freight.
- Production adaptability and stabilityCompatible with fully automated production lines, maintaining dimensional stability and preventing light leakage.
- White or black gridHD-CPC-TGW and HD-CPC-TGB, at 318 µm ±5% total thickness.

Questions about Transparent Grid Black/White
How does the grid pattern align with the cells?
The grid coating is printed to match the cell layout of the module so the reflective areas sit in the gaps. Send your cell pitch and layout when specifying.
Does it cause light leakage?
No — preventing light leakage while maintaining dimensional stability on automated lines is one of its published characteristics.
Is the black version for all-black modules?
Yes, HD-CPC-TGB. For maximum reflectivity in an all-black module, see also the high-reflection black series with its average +2.66% CTM gain.
