More features

• 【High-Efficiency N-Type 18BB Solar Panel】Our AeternaSol 200W solar panel features premium N-Type A+ Grade cells, a high-performance N-type model standing out in the market. Adopting 18 Busbars, it achieves 25.2% high efficiency and stable power output for all scenarios. A+ monocrystalline silicon minimizes microcrack risks; combined with 18BB silver-containing busbars, it ensures low degradation (≤1% first year, ≤0.4% annually) and extended service life, a reliable choice for RV or home backup power.
• 【IP68 Waterproof】Equipped with an exclusive IP68 Waterproof, our solar panels feature advanced potting technology that creates an impermeable seal to prevent water or steam from reaching internal wires. This design minimizes short-circuit risks to the greatest extent, effectively inhibits rust and corrosion, and ensures the solar panel maintains optimal performance even in harsh weather. The junction box’s excellent thermal conductivity enhances heat dissipation, further extending the lifespan of the entire 200 watt solar panel, which is essential for long-term use of solar panels for rv and outdoor applications.
• 【Up to 15% More Energy Output | Advanced Bifacial Design】Capture sunlight from both the front and rear sides for increased energy production. Under optimal reflective conditions, this bifacial 200W solar panel can generate up to 15% more energy than traditional single-sided panels, helping charge batteries faster and maximize solar harvest.
• 【Perfect Fit for Class B Vans & Easy Installation】Measuring 52.8 x 26.4 x 1.2 inches, this 200 watt solar panel is designed to maximize power in a compact footprint — ideal for Class B vans and other tight rooftop spaces. Each panel features pre-drilled holes on the back for quick, hassle-free mounting on large rail mounts or other surfaces, making installation faster and more secure.
• 【Fast Mounting & Easy Expansion】Pre-drilled design facilitates rapid installation with Z-shaped brackets, angled brackets or upright pole mounts. Freely adjustable angles comprehensively meet installation requirements across diverse scenarios.Standard MC4 plugs allow simple wiring and system growth.
