Product Information

About this item

• 【Upgraded 18BB N-Type A+ Cells, Up To 25.6% Max Conversion Efficiency】Equipped with cutting-edge 18 busbar N-Type A+ monocrystalline cells, this 200W solar panel hits 25.6% photoelectric conversion efficiency, outperforming outdated 16BB/9BB panels. Finer 18BB grid lines boost light absorption, cut internal resistance, deliver far more power under cloudy, dawn/dusk weak light, and bring stable power output for your 12V off-grid battery system.
• 【18BB Optimized Grid Design, Minimize Hot Spots & Micro-Cracks, Longer Lifespan】The upgraded 18BB uniform current distribution structure solves core defects of traditional low-busbar panels. It effectively suppresses hot spot overheating and cell micro-cracks caused by uneven current transfer, greatly reducing long-term power attenuation. With first-year degradation ≤1.0% and annual decay only 0.4%, it maintains steady power generation for up to 30 years of outdoor use.
• 【Built-In Bypass Diodes + Low Temperature Coefficient, Stable Output In Shade & High Heat】Integrated bypass diodes offset power loss from partial shading (trees, buildings, uneven sunlight) and avoid overheating damage. Adopted premium N-Type silicon with ultra-low temperature coefficient, far less power drop in hot summer, desert and coastal high-temperature environments. Works reliably from -45℃ to 85℃ without obvious efficiency decline.
• 【Fully Expandable & Wide Compatibility for All 12V Solar Setups】Specially engineered for 12V battery charging, perfectly compatible with all PWM/MPPT charge controllers and mainstream portable power stations. Multiple panels can be wired in series or parallel to build 24V/48V large-capacity solar systems. Ideal for RV, camper van, yacht, cabin, farm rooftop and emergency off-grid backup power.
• 【IP68 All-Weather Durability & Easy Diy Installation with Reliable Warranty】Constructed with 3.2mm impact-resistant low-iron tempered glass, corrosion-proof anodized aluminum frame and reinforced corner guards, rated IP68 fully waterproof & dustproof. Withstands 2400Pa wind load and 5400Pa snow load to resist rain, snow, hail and salt fog. Pre-drilled mounting holes & standard MC4 connectors support quick installation. We offer 10-year material & workmanship warranty plus 30-year power output guarantee (87.4% power retention after 30 years).
