CAPC

HD-CAPC

10⁻²–10⁻³ g/m²·day water transmission in a 325 µm transparent construction, with PID288 and DH2000 degradation under 2%.

Portable and lightweight modules spend their lives in worse humidity conditions than rooftop arrays — folded in a damp boot, hung on a coastal balcony, parked outdoors through a monsoon — and they have no glass to seal them.

HD-CAPC answers that with a water vapour transmission rate two to three orders of magnitude below a plain PET construction, while staying weather-resistant, lightweight and transparent enough to be the published best choice for packaging portable components.

Why this one

  • Water vapour transmission of 10⁻² to 10⁻³ g/m²·dayWhich is the specification that decides whether a glassless module reaches its warranty period in a humid climate.
  • Insulation by structureThe special structure satisfies the insulation requirements for PV modules without an added layer.
  • High reliabilityPower degradation under 2% after PID288 and DH2000 testing.
  • 325 µm ±5% total, transparent20 µm air coating, 300 µm PET middle layer and a 5 µm inner coating with high reflectivity and strong EVA bonding.

Questions about CAPC

What do PID288 and DH2000 mean?

Potential-induced degradation testing at 288 hours and damp heat at 2000 hours — accelerated ageing protocols. Power degradation stays under 2% through both.

Is CAPC transparent or white?

The published colour for HD-CAPC in this construction is transparent.

How does it compare with CPPC/HPPC?

Both hold the same 10⁻²–10⁻³ g/m²·day barrier. CPPC/HPPC adds a dedicated water block layer and is specified for 25-year service life with high transmittance; CAPC is the simpler, lighter construction for portable use.
