HD-SG

HD-SG-F / HD-SG-S / HD-SG-N / HD-SG-T

Reflectivity above 80% and water transmission below 0.5 g/m²·day, in constructions from 540 µm to 1000 µm.

A conventional CPC backsheet reflects above 70% and passes under 2.0 g/m²·day of water vapour. In a glassless module those numbers are not good enough — there is no rear glass adding stiffness and no glass sealing out moisture, so the backsheet has to do both jobs.

HD-SG is that backsheet. Four thickness grades from 540 µm to 1000 µm give you the rigidity to stop deformation-induced cell micro-cracks, while reflectivity above 80% and water transmission below 0.5 g/m²·day beat conventional CPC on both counts.

Why this one

  • Reflectivity above 80%Against above 70% for conventional CPC backsheets — light that would have been absorbed goes back into the cells instead.
  • Water transmission below 0.5 g/m²·dayAgainst below 2.0 g/m²·day for conventional CPC backsheets.
  • Light yet rigidPrevents the component deformation that causes battery micro-cracks, which is the failure mode that glassless construction introduces.
  • Four grades from 540 µm to 1000 µmHD-SG-F at 540 µm, HD-SG-S at 740 µm, HD-SG-N at 890 µm and HD-SG-T at 1000 µm, in white or black.

Values as published by the manufacturer. Tolerances and roll formats are confirmed in writing per order.

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

  • C&I distributed lightweight modules
  • Automotive-integrated modules
  • Balcony modules
  • Carport canopies

Questions about HD-SG

Which grade do I need?

It follows the span and the load. HD-SG-F at 540 µm for smaller modules, up through HD-SG-T at 1000 µm where the module is large or the mounting is unsupported. Send the module dimensions and the mounting method.

Is a black version available?

Yes — the published colour options are white and black.

Does it replace the rear glass entirely?

That is its purpose in a lightweight module: rigidity and moisture barrier without the weight of a rear glass sheet.
