Ultra-thin Flexible HJT Solar Panel — 21.17% Efficiency

Key features

• Advanced heterojunction (HJT) cell technology delivering 21.17% conversion efficiency in a lightweight, flexible format.

• Ultra-thin profile conforms to curved and low-load roofs, trailers, caravans, boats, and other non-traditional mounting surfaces.

• Pressure-sensitive adhesive backing designed for permanent bond to composites, metal, fiberglass, and roofing membranes without heavy racking or drilling.

• Low mechanical load and minimal added weight — ideal for structures with limited load-bearing capacity and mobile applications.

• High performance in diffuse light and elevated temperatures compared with standard thin-film alternatives.

• Robust mechanical flexibility: designed to tolerate repeated flexing and vibrations common in transport and mobile installations.

• Encapsulation engineered for long-term outdoor exposure: moisture-resistant layers and UV-stable materials to protect HJT cells.

• Integrated junction-box options with IP67-rated connectors for simple plug-and-play electrical connections.

• Lightweight fire-rating options and UL/IEC compliance available depending on configuration and regional requirements.

Typical applications

• Caravans, RVs, camper vans and motorhomes

• Marine: yachts, boats, houseboats

• Curved and low-load residential and commercial roofs (metal, membrane, tile-overlays)

• Portable power platforms and emergency-response vehicles

• Off-grid cabins and tiny homes where roof loading is constrained

Benefits

• High efficiency in a compact, low-mass form factor maximizes energy yield where roof area is limited.

• Adhesive bonding eliminates bulky racks, reduces wind uplift risk, and preserves roof aesthetics.

• Reduced installation time and labor compared with conventional framed panels.

• Durable HJT cell chemistry offers stable output and long operational life relative to many flexible alternatives.

Typical performance (example)

• Cell type: Heterojunction (HJT)

• Module efficiency: 21.17%

• Power tolerance: ±3% (model-dependent)

• Operating temperature range: -40°C to +85°C (specific product variants may vary)

• Expected degradation: low first-year loss and stable annual degradation rates (manufacturer datasheet for exact numbers)

Installation notes

• Surface must be clean, dry, and structurally sound. Follow manufacturer surface-prep guidelines for best adhesion.

• Some roof substrates may require primer. Avoid installation over surfaces with active water intrusion or loose coatings.

• For mobile applications, verify adhesive and mechanical retention strategy for the vehicle’s vibration profile. Consider supplemental fasteners at panel edges where permitted.

• Maintain service access to junction-box and connectors. Use proper cable management and strain relief.

Available options

• Custom lengths and segmented cell layouts for irregular roof shapes

• Pre-wired strings and integrated microinverters or power optimizers

• Multiple adhesive systems for different substrates and service conditions

• Fire-rated top-surface options for compliance with local building codes
