Ultra Black 115W Flexible ETFE Solar Panels Back Contact Technology

Revolutionizing Solar Performance with Premium Aesthetics

The Custom Flexible 115W Solar Panel with Back Contact Technology from Couleenergy seamlessly blends cutting-edge solar innovation with a refined, all-black appearance. Designed for performance-critical and design-sensitive applications, this panel redefines what’s possible in flexible solar engineering.

Back Contact Technology: Next-Level Performance

Maximized Light Absorption

Traditional panels lose efficiency due to front-side metal contacts that block sunlight. Our back contact (BC) architecture eliminates these obstructions, moving all connections to the rear. This allows:

• Up to 97% light utilization, compared to 85–90% in standard modules¹
• Higher module efficiency, with commercial ratings reaching up to 24.3%²
• Improved shading tolerance, potentially yielding 30%+ better output in partial shade³
• Enhanced long-term yield, with more energy generation over time compared to conventional models⁴

Note: Performance gains vary by use case and site conditions. See test results or contact us for data sheets.

Sleek Ultra-Black Aesthetics

Designed for projects where visual harmony matters:

• Uniform matte-black surface with no visible grid lines
• Architectural-grade look ideal for homes, RVs, yachts, and commercial roofs
• Low-reflectance finish reduces glare and blends seamlessly with dark surfaces

Flexible, Lightweight & Durable

Bendable & Mount-Ready

• Bends up to 240° for curved surfaces
• Weighs just ~2.0kg
• Slim 3mm profile for space-sensitive installations
• Reinforced eyelets for easy mounting on RVs, boats, tents, or cabins

Built for Challenging Environments

• ETFE surface from Japan: weather-resistant and self-cleaning
• Saltwater corrosion-resistant: perfect for marine use
• Vibration-resistant: ideal for RV and mobile setups
• Wide operating range: -40°C to +85°C

Ideal Applications

This panel thrives in locations standard solar can’t:

• Marine: Yachts, sailboats, and docks requiring curved, corrosion-proof solutions
• RVs: Curved rooftop installs with minimal weight impact
• Luxury Homes: Discreet rooftop or balcony applications
• Commercial Projects: Architecturally integrated solar façades
• Off-grid Systems: Remote or mobile energy where size and flexibility are critical
