Product Description

HIGH-EFFICIENT MONOCRYSTALLINE SOLAR CELL - GRECELL UB200 is a 200-watt monocrystalline solar panel with high conversion efficiency, up to 23.5%, which is much higher than typical solar panels. With excellent 98% transparency, the GRECELL UB200 performs better than similarly-rated polycrystalline solar panels in low-light conditions and much higher than the market's average, converting more solar power into usable electrical energy and further reducing charging time.

PORTABLE & SUPER SLIM - With a folded size of 21.46*22.95*1.77 inches and a lighted weight of only 10.14lbs, the GRECELL UB200 is 30+% lighter than other 200W solar panels and more portable with one hand. With super slim unfolded thickness:0.98inch, it will not take up much space when stored or used. 4 adjustable kickstands, 4 metal reinforced mounting holes to help you fold/hold/hook it up anywhere. Tips: For best results, we recommend using GRECELL solar panels with GRECELL solar generators.

FLEXIBLE & DURABLE - Made with advanced laminated technology and long-lasting ultra-light ETFE material on the surface, can be bent at a certain angle without damage, making it more flexible, durable,weather-resistance, and scratch-resistant than other ordinary PET films and extending its' lifespan more than 2 years. It is IP65 water-resistant that will protect from water splashing (Do not place it under the rain, or soak it in water).

WIDELY COMPATIBLE - GRECELL 200W solar panel uses 4 connectors(DC7909/8, XT60, Aviation Connector, Anderson)which are suitable for most solar generators on the market, especially the bigger ones, such as Jackery/Ecoflow/Anker/Rockpals/Bluetti power station, all GRECELL generator, etc. With your controller(not included) and alligator clip(not included), it can also charge for the 12V batteries, such as the battery of RV/car/boat, Lifepo4, lithium, AGM, lead-acid, GEL, etc.

HASSLE-FREE RECONNECTING - This portable solar panel is engineered with an auto-optimization function for immediate reconnection when sunlight returns after charging interruption. Getting 20% more energy harvesting than a PWM controller, the MPPT controller allows larger currents, and the overcharging cut-off technology ensures the ultra-reliable performance of this solar panel. Moreover, 200W solar panels support series/parallel connections.
