Solar Backsheet Suppliers: Questions About Lucky CPCw1

The Lucky CPCw1 is suitable for PV modules in high-humidity and high-salt-spray environments. Its applications include distributed power stations, ground-mounted power plants, and other projects where modules may face coastal conditions or industrial pollutants.

A buyer planning a coastal installation can evaluate the CPCw1 as a backsheet option where salt spray and humidity are design concerns. For an industrial site, the relevant question is whether the module design and backsheet selection match the site’s chemical exposure. See the Lucky CPCw1 solar backsheet product page for the product reference.

The CPCw1 uses a fluorinated coating with resistance to acids, alkalis, solvents, and salt spray. This protection is intended to reduce the effect of chemical exposure on the backsheet in outdoor environments such as coastal and industrial areas.

The product is therefore a relevant option for module programs that need resistance to acid rain, salt spray, or industrial pollutants. The final selection still needs to match the complete module structure and the expected site conditions.

The CPCw1 uses a damp-heat resistant PET base material. It retained flexibility without embrittlement or cracking after 2,090 hours of dual 85 testing at 85°C and 85% relative humidity. Its UV aging resistance exceeds 200 kWh/m².

These figures help buyers assess material stability for hot, humid module operating conditions and UV exposure. The backsheet’s adhesive layer is formed by fluorinated coating curing and is compatible with EVA encapsulants. It also provides a bonding interface intended to support thermal stability and resistance to localized high-temperature impacts from hot spots.

Before requesting a quotation, send the module construction, EVA encapsulant specification, expected humidity and salt-spray exposure, and planned order quantity to the supplier so the CPCw1 can be reviewed against the intended module design.
