Deep Dive: What Makes TF Series Different?
High conversion efficiency
TF series uses the latest high-efficiency monocrystalline cells or Sunpower cells. Monocrystalline cells can achieve efficiencies of up to 22.8% and SunPower cells of up to 24.4%. This flexible solar panel has a higher conversion efficiency and can provide you with more power.
Extreme Durability
Built with advanced polymer composite and ETFE materials, TF panels resist corrosion, UV, and moisture — keeping stable output in salty air, rain, and strong sunlight.
Reinforced for Impact & Foot Traffic
TF Series panels are built with a reinforced multi-layer composite structure that absorbs impact and disperses pressure. With optimized cell spacing and a wear-resistant surface, they withstand physical stress like stepping and handling — without cracks or performance loss.

What Our Partners Are Saying
Frequently Asked Questions About TF Series Flexible Solar Panels
Yes. TF Series panels are step-on rated and have been tested with 14,700 steps over 49 days, resulting in less than 3% power loss and zero structural failure. The reinforced multi-layer composite structure absorbs and redistributes foot pressure without causing micro-cracks.
Yes. TF panels carry an IP68 waterproof rating and have passed 672 hours of salt mist testing per IEC 61701, with power degradation below 2%. Every layer is sealed to prevent salt-air corrosion from reaching internal circuitry.
TF-M uses monocrystalline cells with up to 22.7% efficiency and supports 600V DC systems. TF-S uses SunPower IBC cells with up to 24.4% efficiency but is limited to 200V DC. Choose TF-S for maximum efficiency in limited space; choose TF-M for cost-effective larger installations.
TF panels can bend to a 260 mm arc without micro-cracking, verified by EL imaging. This makes them suitable for curved RV rooftops, yacht hulls, and other non-flat mounting surfaces.
No. TF panels use ETFE surface material instead of PET. ETFE is chemically inert and UV-stable, preventing the yellowing and hazing common in lower-grade flexible panels, even after years of direct sun exposure.
Yes. Sungold supports full OEM/ODM customization including custom dimensions, junction box placement (front or rear), pre-applied adhesives, stainless steel eyelets, and private labeling. Minimum order quantities apply — contact sales for details.
Sungold recommends ribbon-bond installation using 3M VHB tape, which creates a 3 mm air gap beneath the panel. This gap improves heat dissipation, keeping cells approximately 15°C cooler than direct-glue mounting, which improves both efficiency and lifespan.
TF Series panels are certified to CE and ROHS standards. Waterproof testing follows IEC 60529 (IP68), and salt mist resistance follows IEC 61701. Downloadable certificates are available on the Sungold support page.
