Advanced EVA/POE Films for Floating Solar Plants
Discover how Foshan Ruihong's cutting-edge encapsulation solutions enhance durability and efficiency in floating solar applications worldwide
Optimizing Floating Solar Plants with Advanced EVA & POE Encapsulation Films
Floating solar plants represent one of the most innovative applications in renewable energy, utilizing underutilized water surfaces to generate clean electricity. As a leading manufacturer of solar encapsulation films since 2013, Foshan Ruihong has developed specialized EVA and POE films that address the unique challenges of floating PV installations.
The Unique Demands of Floating Solar Applications
Unlike traditional ground-mounted systems, floating solar installations face distinct environmental challenges:
- Constant exposure to high humidity levels (up to 100% RH)
- Enhanced UV radiation due to water reflection
- Thermal cycling and mechanical stress from wave action
- Potential for biological growth and contamination
- Corrosive water environments (saltwater or chemically treated)
Why EVA and POE Films Matter in Floating PV
Our Solar EVA Films provide exceptional optical clarity and adhesion properties, while our POE Films offer superior moisture resistance and durability. When combined, they create the perfect encapsulation solution for floating solar modules.
Foshan Ruihong's specialized floating solar-grade films demonstrate 40% better moisture resistance and 25% longer service life compared to standard encapsulation materials, making them ideal for aquatic environments.
Technical Advantages of Our Floating Solar Films
After extensive R&D and field testing, we've engineered films specifically for floating applications:
| Property | Standard EVA | Ruihong Floating EVA | Ruihong Floating POE | Test Method |
|---|---|---|---|---|
| Water Vapor Transmission (g/m²/day) | 25-35 | 15-20 | 5-8 | ASTM E96 |
| UV Resistance (kWh/m²) | 180 | 250+ | 300+ | IEC 61215 |
| Adhesion Strength (N/cm) | 30-40 | 45-55 | 50-60 | ASTM D903 |
| Hydrolytic Stability | Good | Excellent | Outstanding | 85°C/85% RH 2000h |
| Service Life (Years) | 20-25 | 28-30 | 30+ | Accelerated Aging |
Case Study: 50MW Floating Plant in Southeast Asia
In 2024, a major floating solar installation in Thailand selected Foshan Ruihong's specially formulated POE films for their 132,000-panel installation. After 18 months of operation:
- Zero moisture-related degradation reported
- Degradation rate measured at just 0.28%/year
- Maintenance costs reduced by 35% compared to standard films
- ROI achieved 8 months ahead of schedule
Custom Solutions for Unique Challenges
Every floating solar project presents unique environmental conditions. Our team of engineers can develop custom encapsulation films tailored to your specific water chemistry, climate, and performance requirements.
Future Innovations in Floating Solar Encapsulation
At Foshan Ruihong, we're continuously advancing our film technology:
- Self-healing formulations: Films that automatically repair micro-cracks caused by wave stress
- Anti-fouling additives: Reduce biological growth on module surfaces
