WERCHTAY 200W Solar Panel, High-Efficiency 18BB Monocrystalline Module, 12V PV Power Charger for RV, Marine, Home Backup and Off-Grid Systems

<b>Next-Generation 200W Off-Grid Power by WERCHTAY</b><br> Empower your adventures with the WERCHTAY 200W 18BB Solar Panel. Engineered for high-efficiency energy harvest, this panel combines advanced N-Type cell technology with a rugged, all-weather design. Whether you are upgrading your RV, powering a marine vessel, or setting up a home backup system, WERCHTAY delivers reliable electricity wherever the sun shines.<br><br> <b>Advanced 18BB &amp; N-Type Technology</b><br> Our 18-Busbar (18BB) architecture represents the peak of solar engineering. By increasing the number of busbars, we’ve reduced internal resistance and shortened the electron travel path, resulting in a 25.2% conversion efficiency. The N-Type cells ensure zero Light-Induced Degradation (LID), keeping your power output stable for over 25 years.<br><br> <b>Technical Specifications:</b><br> Maximum Power(Pmax): 200W<br> Maximum powervoltage(Vmp): 18.2V<br> Maximum power current(lmp): 10.9A<br> Open circuit voltage(Voc): 22.1V<br> Short cireuit current(lse): 12.1A<br> Power tolerance: ±3%<br> Size: 1340*670*30mm/52.75*26.37*1.18in<br><br>

• Featuring premium 18BB (18-Busbar) A-grade 166mm cells, this 200W panel minimizes energy loss and maximizes current collection. Compared to standard 5BB/9BB panels, the 18BB architecture significantly reduces the risk of micro-cracks and offers a 30% longer service life.
• Powered by high-density monocrystalline cells, WERCHTAY achieves a breakthrough 25% conversion rate. This allows you to generate more power in a smaller footprint—perfect for space-limited setups like RV roofs, van conversions, or marine decks.
• Optimized for 12V battery charging, this panel features integrated bypass diodes to protect cells from overheating. These diodes allow for continuous energy harvest even during partial shading, ensuring your system stays powered 24/7.
• Built to survive the toughest elements, our 12V monocrystalline panel is IP67 waterproof and engineered to withstand extreme 2400Pa wind pressure and 5400Pa heavy snow loads. It delivers consistent performance in rain, snow, or intense sun.
• Ready to use out of the box with pre-installed solar connectors and pre-drilled holes for fast mounting. Each panel undergoes rigorous factory testing to ensure flawless performance for your 12V, 24V, or 48V off-grid configurations.
