A+ Class Cells, Up to 25% Efficiency 200 watt solar panel uses advanced N-Type A+ Grade solar cells and advanced 18 BB Silver-bearing Full Welding Busbars technology (which improves photoelectric conversion efficiency and ensures longer service life compared to traditional 10BB/12BB solar cells) with an increased cell efficiency of 25% EL tested, which features traditional panels surpasses.

No energy is discharged at night By using the reverse current-blocking diode technology, photovoltaic systems achieve 'lossless' operation during night hours, improving the efficiency of energy use while increasing safety and durability.

IP68 Waterproof Certification Exclusively filled with polyurethane polymer Junction box. It prevents water or steam from reaching the wires inside, IP68 rated for dust and water resistance, 200W solar panel is designed to withstand dirt, splashes and rain effortlessly. The corrosion-resistant aluminum alloy frame ensures decades of reliable outdoor use. Designed for extreme conditions, it can withstand 2400 Pa wind pressure and 5400 Pa snow load.

Upgraded MC4 Connector Made of high-quality galvanized copper for superior conductivity, effectively reducing resistance and heat generation and increasing transmission efficiency. PPO engineering plastic, it provides exceptional heat resistance and anti-aging properties. Oversized design enhances structural integrity and delivers superior protection classes, ensuring reliability in demanding outdoor conditions. Standard MC4 interface for plug-and-play functionality and effortless installation.

11 AWG 100% Oxygen-free Copper Wire Made of high-purity oxygen-free copper (OFC) with a conductivity of 99.99%, provides lower resistance and more efficient transmission, and is suitable for processing currents up to 25 amps. In addition to the standard insulation, it features an extra UV-resistant sheath that effectively resists prolonged exposure to sunlight, high temperature aging and moisture corrosion.
