215W Anti-Shading Bifacial Solar Panel,Callsun N-Type 16BB Monocrystalline PV Module, Over 25% High Efficiency,Ideal for 12V System,RV,Marine,Portable Power Station,Off-Grid

【No More Shutdowns from Partial Shade】While ordinary panels can shut down completely from partial shade, the Callsun 215W anti-shading solar panel features 4 independent power zones. If shade covers any zone, the remaining modules continue running at full voltage. This independent design retains up to 75% more power compared to standard panels, ensuring steady all-day energy whether you're RVing under trees, dealing with mast shadows, or camping by mountain ridges. 【Stable Vmp & Extended Life】When partially shaded, most solar panels suffer a Vmp drop that forces MPPT restarts, creating hot spots and stress. Callsun’s 4-modules design with multiple bypass diodes keep Vmp unchanged even with one zone covered—no restarts, no stress, just years of reliable service. 【Bifacial Technology, Catches Extra Power】 Bifacial solar panel captures reflected light (from snow, sand, or white roofs) on its backside to generate up to 7-30% more energy daily. Make your RV/rooftop/marine space work harder and earn more. 【Over 25% High Conversion Efficiency】Built with premium A+ N-Type cells, it outperforms traditional panels with higher power output and exceptional stability. Its superior low-light performance ensures you harvest energy longer, for a steady and dependable power supply. 【Perfectly suited for 12V systems】 Callsun 215W Solar Panel (Vmp 17.37V, Voc 20.41V，Imp 12.38A) is ideal for 12V battery system and compatible with portable power stations such as the Jackery Explorer 1000 plus and Explorer 5000 plus, the Bluetti ELITE 100 V2, ELITE 200 V2, AC200L, AC300, and AC500, as well as the Ecoflow Delta pro, Delta 2, Delta 2 Max, DELTA 3, Delta 3 Plus, Delta pro 3, RIVER 2 pro, and River 2 Max. 【12-Year Quality Warranty, 25-Year Power Warranty】Each Callsun 215W bifacial solar panel is backed by a 12-year product warranty and a 25-year power warranty, ensuring it retains at least 84.5% of its initial power generation efficiency after 25 years. 【Quad-Cell Shading Tolerance, Stable Power Output】Callsun 215W solar panel adopts an innovative four-module parallel structure with 14 built-in bypass diodes, dividing the panel into four independent 55W power generation units. If any one module is fully shaded by obstacles such as snow, leaves, or dirt, the other three modules continue to operate normally and maintain stable voltage output. Compared to conventional solar panels, Callsun’s anti-shading performance is improved by 75%, effectively ensuring continuous and stable power output while significantly reducing generation interruptions.
【N-Type 16BB Cells, Over 25% High Conversion Efficiency】Callsun 215W solar panel uses premium A+ 182mm monocrystalline silicon cells, combined with advanced N-Type technology and a 16BB multi-busbar design, achieving a conversion efficiency of over 25%. Compared with traditional P-Type cells (15%–23% efficiency), N-Type cells provide higher power output, more stable operation, and superior power generation performance under low-light conditions.
【Bifacial Power Generation, Significant Energy Gain】Callsun 215W bifacial solar panel is equipped with a high-transparency backsheet, allowing it to absorb both direct front sunlight and reflected/scattered light from the rear. When installed over reflective surfaces such as snow, sand, or high-reflectivity roofs, the backside can deliver an additional 5%–25% power gain, significantly increasing the overall power generation revenue of the system.
【Split-Type Junction Box Design, Flexible Installation & Easy Maintenance】Callsun solar panels feature an innovative split-type junction box design that breaks through the limitations of traditional integrated junction boxes. Independently distributed junction boxes facilitate easy series/parallel connection and flexible system configuration. This design also promotes uniform heat dissipation, reducing the risk of localized overheating. In the event of a single point failure, only the corresponding module needs to be replaced without disassembling the entire system, greatly saving maintenance cost and time.
【Compact & Lightweight, Easy to Install】This 215W solar panel measures 55.98" × 30.16" × 1.38" and weighs only 25.38 lb. With its compact structure and ample power output, it is specifically designed for limited spaces. Compared to other panels of the same power class, it is 10%–15% smaller and lighter. Pre-installed mounting holes allow quick and secure fixation on roof rails or flat surfaces, making installation simple and reliable.
【IP68 Top-Level Protection, Ready for Rain & Dust Challenges】To cope with changing outdoor environments, Callsun solar panels are equipped with an IP68-rated sealing system that completely prevents dust ingress and withstands continuous underwater immersion. Whether exposed to heavy rain, blowing dust, or road splashes, the internal circuits remain dry and safe, ensuring long-term stable system operation and significantly improving product durability.
【Rugged & Durable, Unaffected by Extreme Weather】Callsun 215W monocrystalline solar panel is built with 3.2mm high-strength tempered glass and anti-corrosion aluminum alloy frame. Its robust structure can withstand 2400Pa wind load and 5400Pa snow load, easily coping with typhoons, snow accumulation, and other extreme weather conditions to achieve all-weather reliable power supply. The low temperature coefficient (–0.3%/K) effectively reduces power loss at high temperatures, ensuring high efficiency output even in hot seasons.
【Long-Term Warranty, Worry-Free After-Sales】Each Callsun 215W bifacial solar panel comes with a 10-year product warranty and a commitment to maintain at least 84.5% power generation efficiency after 25 years.
