UKSOL Flex 400W HJT Flexible — UKS-FLEXI-400W
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
For exact electrical specifications, warranties, and mounting accessories, consult the product datasheet and installation manual supplied by the manufacturer.
