Callsun N-Type 16BB 400W Bifacial Solar Panel, 2×200W Solar Panels | 25.6% High Efficiency, Dual-Module Anti-Shading Design, for RV Van Marine Rooftop Home Off-Grid 12V/24V Systems

Introducing the Callsun N-Type 200W Solar Panel, a high-efficiency rigid solar panel designed for residential, RV, marine, off-grid, and ground-mounted solar power systems. This 200 watt solar panel utilizes advanced N-type monocrystalline solar cells, delivering up to 25% conversion efficiency. Compared with standard P-type solar panels (typically 23–23.5% efficiency), N-type technology provides higher power output, improved reliability, and lower long-term performance degradation. This bifacial 200W solar panel features a high-transparency backsheet that captures solar energy from both the front and rear sides. By harvesting direct sunlight as well as reflected and diffuse light, the bifacial design can increase total energy yield by up to 30%, especially when installed over reflective surfaces such as light-colored rooftops, gravel, sand, or snow. This makes the panel well-suited for rooftop solar, RV solar systems, marine environments, and ground-mounted installations. The panel incorporates advanced 16BB (busbar) cell technology, which enhances current collection efficiency, improves photoelectric conversion, and helps reduce power loss caused by hot spots and micro-cracks. This robust cell architecture supports more stable energy production and contributes to a longer operational lifespan. Anti-Shade Parallel Design for More Consistent Output The Callsun 200W solar panel features a dual-module parallel (TwinCell-style) circuit design, effectively dividing the panel into two independent operating sections. When one section is partially shaded by nearby objects such as trees, roof structures, or equipment, the unshaded section can continue generating power. This design significantly reduces partial shading losses and supports more consistent daily energy harvest in real-world installation environments. Optimized Voltage for Portable Power Stations With an open-circuit voltage (Voc) of 27.31V, two Callsun 200W panels connected in series deliver a combined voltage safely below 60V, making them ideally suited for most modern portable power stations and solar generators with 60V input limits. This optimized voltage range ensures efficient MPPT operation without exceeding system voltage constraints, providing reliable compatibility while maximizing charging efficiency for mobile and off-grid energy systems. Split-Type Junction Box Design for Flexible System Configuration This Callsun solar panel features an innovative split-type junction box design, allowing independently distributed junction boxes for flexible series and parallel system connections. Compared with traditional integrated junction box designs, this structure promotes more uniform heat dissipation, reduces the risk of localized overheating, and simplifies system expansion. In the event of a single-point failure, only the affected module requires replacement—minimizing downtime, maintenance complexity, and long-term system costs. Measuring 51.3 x 30.3 x 1.4 inches and weighing 23.8 lbs, the Callsun 200W solar panel is engineered for easy installation in space-constrained environments such as Class B vans and compact rooftops. Pre-drilled mounting holes enable compatibility with standard solar mounting systems, including Z-brackets and universal rail mounts. This product includes the solar panel only; mounting hardware and accessories are sold separately. Built for long-term outdoor use, the panel features low-iron fully tempered glass, a corrosion-resistant aluminum frame, and an IP68-rated waterproof junction box and connectors. The panel is engineered to withstand harsh outdoor conditions, including high wind loads and heavy snow environments. Laboratory testing indicates an operational lifespan of up to 30 years, exceeding the typical 25-year lifespan of conventional P-type solar panels. With a low temperature coefficient of -0.3%/°C, the panel maintains higher power output in hot climates, reducing heat-related energy loss and supporting stable performance in high-temperature environments. Each Callsun 200W solar panel is backed by a 25-year performance warranty guaranteeing at least 84.5% output, along with 10 years of technical support covering materials and workmanship. Designed for reliable, long-term energy production, this N-type bifacial solar panel is a durable and scalable solution for modern solar power systems.
