ENGAGE™ PV Polyolefin Elastomers: The Material of Choice for PV Encapsulants

As the global photovoltaic market continues to grow, material selection can be a critical component in the ongoing success of PV module manufacturers. ENGAGE™ PV Polyolefin Elastomers (POEs) help make the choice for PV encapsulant films easier with opportunities for exceptional long-term performance, reliability, and lower overall costs.

ENGAGE™ PV POEs offer improved performance compared to most competing materials

Top and bottom PV encapsulant films made with ENGAGE™ PV POEs offer opportunities to significantly:

  • Increase power generation, electrical efficiency, reliability, and service life
  • Improve resistance to potential induced degradation (PID) with "PID Zero" performance (modules exhibit virtually no PID)
  • Reduce the levelized cost of electricity (LCOE) as well as total system costs

Enhanced Power Retention
Average power loss %"PID Zero" performance is enabled by films made with ENGAGE™ PV POEs. Third party testing by Fraunhofer showed ENGAGE™ PV POE exhibited virtually no PID during service life, with a power loss of 0.3% versus 35% with EVA-based film.1

Weathering
Normalized Power Output After alternating cycles of damp heat and QUV exposure over extended periods of time, ENGAGE™ PV POE showed more consistent power as compared to EVA.

Encapsulant Film Degradation Under UV

Even after 10,000 hours of Xenon Arc weathering testing, encapsulant films made with ENGAGE™ PV POEs did not show increased yellowness index (a problem often associated with EVA).2
