India's 1st NABL Accredited

'Photovoltaic Laboratory' 

For Encapsulants & Backsheets

A large number of field failures of solar power plants are caused due to substandard or compromised solar module Encapsulants and Backsheets.

Quality checks are hence imperative. However, it is impossible to ascertain module quality by simply conducting a visual check. Thus periodic testing of the components used in modules becomes a significant indicator of PV module quality.

Hence RenewSys has established India's 1st NABL accredited laboratory with a testing facility specifically for PV Module Encapsulants, Backsheets, and their raw materials. 

An independently run facility, the lab is one of its kind, that ensures quality assurance on demand for system integrators, solar plant developers, module manufacturers, and Encapsulant & Backsheet manufacturers alike.

Run by a team of experts from the solar industry, it has the capability to test all polymers including Encapsulants (EVA & POE), Backsheets and their raw materials.     

Who should avail of this facility:

- PV Module Manufacturers - to ensure the reliability of their modules' performance, they test the quality of the Encapsulants and Backsheets that they are purchasing.

- Solar Project Developers, EPC Companies, and System Integrators  - to affirm the reliability and quality of the polymer components (like Encapsulant and Backsheet) used in the modules, that are being installed in their projects.

- Encapsulant & Backsheet Manufacturers - to test raw materials that will be used in the manufacture of Encapsulants and Backsheets, and to use these test reports to supplement datasheets and product descriptions​.

The lab tests the following critical parameters for Encapsulant and Backsheet performance: 

  • Gel content/Crosslinking rate

  • Adhesion Strength

  • Tensile & Elongation

  • Transparency

  • UV cut off wavelength

  • Yellowness Index

  • Opacity

  • Volume resistivity

  • Thickness

  • Density

  • Melt Flow Rate

  • Thermal Shrinkage

  • Wetting tension of the sheet

  • Residual solvent content in Backsheet
