Product Highlights

✅ Extremely Flexible: Update to latest version size: 36.22inch*23.22inch*0.11inch/920*590*3MM, The minimum radius of the arc that a 100 watts flexible solar panel can reach is 45cm (17.7 in). It is capable of meeting a wide range of applications where standard solar panels can be inconvenient to mount, suitable for off-grid applications that include trailers, marine, boats, cabins, tents, cars, trucks, yachts, RVs, campervans, caravans, sheds, residential rooftop, home garden outdoor, or any other irregular surface.
✅ Lightweight & Easy to Install: It is only 0.1 inches in height and weighs only 4.4LB (2KG), the solar panel is easy to transport, install, hang and remove. The metal pre-drilled holes and PV solar connectors help you install easily and quickly.
✅ 9 Busbars Solar Cell, High Conversion Efficiency: 9BB & A Grade Monocrystalline silicon solar cell provides high conversion efficiency up to 23%. The narrower busbar space and more cells receiving surface bring lower cost and increase the output of the PV module. Compared with 5BB panel, the 9BB solar panel ensures lower risks of microcracks and longer service life.
✅ Waterproof & Dustproof: This flexible solar panel is equipped with IP67-rated junction box to effectively block water splashes and dust from outside, making it perfect to be used outdoors. It is much more durable than traditional glass and aluminum model solar panels. 2 pieces bypass-diodes are built in the junction box.

Product Highlights

✅ Bifacial Transparent Backsheet, 30% Higher Power Output：Our foldable bifacial flexible solar panel comes with transparent rear side rather than opaque backboard. It captures sunlight from both front and back sides, absorbing direct sunlight plus reflected & diffused ambient light, boosting overall power generation by up to 30% vs conventional single-sided solar panels.
✅ Upgraded 18BB Monocrystalline Cells, 25% Max Conversion Efficiency：Equipped with advanced 18BB mono cell tech (upgraded from competitors’ 16BB design), it reaches a high 25% photoelectric conversion efficiency. Thinner busbar ribbons cut shading area by 22% to expand light-receiving surface for higher efficiency and longer lifespan. Directly compatible with 38V batteries; series connection of multiple panels supports 48V battery charging for customized off-grid power system.
✅ Double Fiberglass & Premium ETFE Surface, Crack-proof & Long Durability：Constructed with dual-layer fiberglass protection to fully wrap monocrystalline cells against impact damage, effectively lowering cell cracking risk and extending service life. Adopting premium ETFE instead of ordinary PET as surface material, the panel features scratch-resistant, self-cleaning and sand-proof performance, avoiding delamination after long-term outdoor use and preventing abrasion damage during transportation and daily maintenance.
✅ Foldable Ultra-light Compact Design, Space-saving & Low Roof Load：Unfolded dimensions: 56.2 × 44.4 inch; Folded compact size: 44.4 × 28.1 inch. Net weight only 10.36 lb; Benefiting from N-type 18BB cell configuration, the panel is ultra-lightweight and compact to reduce roof load greatly. Compared with assembling multiple small-wattage panels, our single high-power module saves 11% installation space and lessens wiring loss. Foldable design allows more panels to be arranged on RV/boat roof to expand your off-grid power system for daily household electricity needs.
