  14. Why choose DuraShield backsheet products?

  15. Look what can happen if you use the wrong backsheet… Corrosion in connections caused by cracks in backsheet Delamination of BS after 3 yearsexposure in Germany • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  16. All DuraShield backsheets provide high physical protection, electrical insulation & the right appearance Physical protection Enabling a 25 year outdoor PV module lifespan Increased efficiency in some applications Electrical insulation Right appearance Moisture protection • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  17. Hanita produces four types of backsheets (BS) for the leading PV technologies DuraShield KPE Fluoropolymer laminate BS, for c-Si modules DuraShield CPE High durability FP coated laminate BS, for c-Si modules DuraShield KAPE Low weight, high barrier BS solution for Thin Film technologies DuraShield Back Contact Electrical circuit backsheet for Back Contact (EWT/MWT) technologies • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  18. DuraShield KPE’s classic FP film construction delivers enhanced long-term performance for c-Si modules DuraShield KPE K = Kynar® PVDF Fluoropolymeric film P = Polyester film E = EVA • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  19. DuraShield KPE is a proven technology targeting traditional module manufacturers Cost Effective Economical alternative to PVF constructions Enhanced Reflectivity Exceptionally white EVA layer Excellent Durability Long term weatherability retains bright whiteness and reflectivity • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  20. DuraShield KPE is TUV certified for >1000VDC and UL IEC 61730-2:2004 Maximum permissible 1053 VDC System voltage • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  21. DuraShield KPE easily withstands 2000 hours damp heat 2000 hours testing • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  22. DuraShield CPE replaces the Kynar FP film laminatewith an equally durable Fluoropolymeric coating DuraShield CPE Cost Effective C = Coating of Fluoropolymer P = Polyester film E = EVA • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  23. The DuraShield CPE solution delivers a price advantage without compromising performance Fluoropolymer Coating EVA PET Patent pending ultra-white EVA layer gives high VIS light reflectance (higher output power from the module) + good adhesion to EVA encapsulant. Provides electrical insulation and mechanical strength. Protected by Fluoropolymer layer. Gives protection from weathering, cost effectively. • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom

  24. DuraShield KPE gained TUV & UL approval. So did the competitors. Look what happened after 2000 hours… Competitor Backsheet DuraShield KPE ∆E = 2.0 ∆E = 4.4 Market leading competitor’s backsheet yellows drastically after aging test of 2000 hours of damp heat. DuraShield KPE is more reflective and more effective than the competitor’s leading product. • Why Hanita Backsheets: KPE CPE KAPE Back-Contact Custom
