Double-Sided Coating Series
White CPC, Black CPC
HD-CPC / HD-CPC-B
The 1500 V workhorse: 303 µm, coated both faces, white or black.
Most of the modules in the field are built on a backsheet like this one, and the thing that separates a good one from a merely adequate one is whether both faces are coated. Coat only the inside and the PET core meets the weather directly; coat only the outside and EVA adhesion becomes the weak link.
HD-CPC is coated on both: a 10 µm outer coating protecting the PET against heat and weather, and a 5 µm inner coating providing high reflectivity and strong EVA bonding, around a 288 µm insulating core rated for 1500 V system voltage.
Why this one
- Double-sided coating technologyExcellent heat and weather resistance from the outer coating, EVA bonding and reflectivity from the inner.
- High reflectivityEnhances the module's power generation efficiency by returning inter-cell light to the cells.
- Rated to 1500 V system voltageThe standard for utility-scale strings.
- 303 µm ±5%, white or black10 µm air coating, 288 µm PET middle layer, 5 µm inner coating.

Storage and shelf life
High storage stability with no special storage requirements. Warranty period is one year under cool, dry storage conditions; laminating process generality should be evaluated after that period.
Applications
- Utility-scale PERC single-glass modules
- Distributed single-sided generation
- Portable applications
Supplied from
Suzhou, Jiangsu, China — and PT. Hondol Material Indonesia, Batam, for customers served from Indonesia.
Questions about White CPC, Black CPC
Is this the standard product to start with?
For a utility PERC single-glass module, yes. The transparent, grid, aluminium and fluorine-free constructions are all departures from this platform for specific reasons.
White or black?
White for maximum reflectivity and coolest operation, black for appearance. For an all-black module the high-reflection black series recovers more of the CTM loss.
What system voltage is it designed for?
Modules with a system voltage of up to 1500 V.
