Solar panel backsheets play a vital role in the efficiency of the Photovoltaic module, providing

• Physical protection from damage, moisture and UV degradation
• Electrical insulation
• Long-term unit stability

Higher grade backsheet laminates can also help upgrade appearance and the ability to blend more subtly into the environment. They can also improve the efficiency of c-Si modules by increasing internal reflectance.
Despite the abundance of backsheets in the market, the PV industry is still seeking competitively priced, durable products that offer excellent processability. Hanita Coatings rises to the challenge with DuraShield - a range of laminates dedicated to providing precisely these benefits. DuraShield® laminates are based on top-grade, proven-performance raw materials, and Hanita’s exceptional coating and lamination know-how:

		DuraShield® KPE  - Maintains and retains module performance for the long term
		Our classic traditional backsheet film for c-Si modules, DuraShield® KPE, integrates the proven weatherability of Kynar® FP film. In addition to good mechanical and dielectric properties, weatherability and moisture protection, the KPE construction also delivers excellent processability, with high affinity to the EVA layer to the encapsulant.
		DuraShield® CPE backsheets In this exceptional backsheet, we replaced the PVDF film of the KPE product with a Fluorpolymeric coating, which gives the same long lasting performance, but at extremely cost-effective prices.
		DuraShield® KPE and CPE PV backsheet laminates are certified by TÜV for >1000 volt partial discharge
		DuraShield® KAPE This backsheet was developed to replace the glass backlayer in CIGS, CdTe, a-Si and other thin-film modules.  We add a layer of aluminum to our classic KPE (or CPE) films to protect against damaging moisture.
		DuraShield® Back-Contact Sheets DuraShield Back-Contact foil integrates electrical connections into the backsheet itself.  Our patent-pending technology reduces unit costs by replacing the expensive copper with a special aluminum  layer that still allows panel manufacturers to use standard adhesives and soldering processes.
