200W Portable Monocrystalline Solar Panel Overview A 200W solar panel using grade A monocrystalline cells, designed for conversion efficiency, lightweight portability, and broad compatibility. The panel is built with a reflection ETFE cell cover and a PET surface for improved transmittance, durability, and easier cleaning. Integrated protection features and standard MC4 connector make it suitable for vehicle, marine, and offgrid battery charging applications. Key benefits Efficient power generation: Typical battery efficiency 19.8 percent; ETFEcovered monocrystalline cells enable conversion rates in the 19.6 to 23 percent range under conditions. Delivers reliable output under standard test conditions of 1000 W/m2 irradiance, 25 C, AM 1.5. Portable and lightweight: Constructed from advanced polymer materials to be about 50 percent lighter than conventional panels, making transport and installation easier. Durable and weather resistant: PET surface with scratch resistance, heat resistance, and water resistance for longer service life and easier cleaning. Builtin protection: Antireverse diode and protections against overheating, overcurrent, and overload automatically detect connected devices and supply charging current. Flexible mounting and compatibility: Six copper mounting holes and standard MC4 connector for straightforward attachment and connection to batteries, controllers, and chargers. Technical specifications Rated power: 200W Tolerance: +/5% Open circuit voltage Voc: 19.2 V to 36 V Maximum system voltage: 16 V to 24 V Shortcircuit current temperature coefficient Isc: (0.10 +/ 0.01) %/C Opencircuit voltage temperature coefficient Voc: (0.38 +/ 0.01) %/C Power supply temperature coefficient Voc: 0.47 %/C Operational temperature range: 40 C to +80 C Connector type: MC4 Panel material: PET surface, ETFE cell cover Mounting: Six copper mounting holes Standard test conditions: Irradiance 1000 W/m2, temperature 25 C, AM 1.5 Applications and practical use scenarios Vehicle and mobile power: Mount on cars, motorcycles, or roof racks to maintain and charge auxiliary batteries during travel or when parked. Marine and boating: Provide supplemental charging for boat batteries and onboard systems while anchored or underway. Offgrid and outdoor activities: Use with portable battery systems or charge controllers for camping, RVs, emergency backup, and small household appliances. Usage and maintenance notes Point the panel directly toward the sun for charging performance. Avoid placing the panel outdoors for emergency charging in rainy conditions to prevent short circuits. Do not scratch the panel surface with sharp objects; clean gently to maintain transmittance and longevity. Ensure secure MC4 connections and correct polarity when connecting to batteries or charge controllers. This 200W panel is suited for users needing a lightweight, durable, and efficient solar charging solution compatible with common MC4based systems and battery setups.
