Request Technical ConsultationSolar EVA/POE Films in BIPV: Transforming Buildings into Energy Generators
Building Integrated Photovoltaics (BIPV) represents the cutting edge of sustainable architecture, seamlessly integrating solar technology into building materials. As a pioneer in solar encapsulation films since 2013, Foshan Ruihong Industry & Trade Co., Ltd has developed specialized EVA and POE films that meet the unique demands of BIPV applications. This article explores how our advanced encapsulation technologies are enabling architects and builders to create energy-positive structures.

The Critical Role of Encapsulation Films in BIPV
Unlike traditional PV installations, BIPV systems serve dual functions as both building materials and energy generators. This requires specialized encapsulation films that deliver:
Enhanced Durability
BIPV modules must withstand constant exposure to environmental stressors while maintaining structural integrity as part of the building envelope.
Aesthetic Flexibility
Our films enable customizable transparency and color options to meet architectural design requirements without compromising efficiency.
Superior Fire Resistance
Meeting stringent building fire safety standards through advanced flame-retardant formulations in both EVA and POE films.
EVA vs. POE Films for BIPV Applications
Both Solar EVA Films and POE Films offer distinct advantages for different BIPV implementations:
Property | EVA Films | POE Films |
---|---|---|
Transmittance | 91-92% | 92-93% |
PID Resistance | Good | Excellent |
Water Vapor Transmission | 20-25 g/m²/day | <5 g/m²/day |
Thermal Stability | Up to 85°C | Up to 105°C |
Fire Rating | Class B | Class A |
Application Flexibility | Standard architectural integration | High-performance & demanding applications |
BIPV Implementation Case Studies
Ruihong films have been instrumental in several landmark BIPV projects:
Shanghai Expo Pavilion
Our custom-formulated EVA films enabled the creation of curved, semi-transparent solar facades that generated 35% of the building's energy needs while providing natural lighting.
Singapore Green Tower
POE films protected integrated solar windows in this tropical high-rise, maintaining >92% efficiency despite 90% humidity levels and salt exposure.
Berlin Smart Office Complex
Our fire-retardant custom encapsulation films met stringent EU building codes while enabling seamless solar integration into roofing materials.
Future Innovations in BIPV Encapsulation
Ruihong is developing next-generation encapsulation technologies specifically for BIPV:
- Color-neutral films with <1% efficiency loss
