50W Monocrystalline Solar Panel Lightweight, Durable, Expandable Overview This 50 watt monocrystalline solar panel provides a compact and portable power source for off grid and mobile applications. The panel is factory tested for quality and assembled with an aluminum frame and tempered glass molded in waterproof resin for long term durability. Key benefits Versatile power outputs: USB 5V output for small devices and DC output around 18V for battery charging or system input. Compatible with 12V and 24V systems when used with a PWM charge controller; supports common 10A to 60A controllers with LCD and dual USB ports. Expandable array options: panels can be combined to reach up to 240W for 12V systems or 480W for 24V systems. Lightweight and compact for easy transport and installation. Rugged construction for outdoor use; panel surfaces are waterproof to IP65. Note the junction box should be kept dry. Specifications Maximum power: 50 watts Open circuit voltage (Voc): 20 V Maximum supply voltage (Vmp): 18 V Short circuit current (Isc): 1.5 A Maximum supply current (Imp): 1.1 A Outputs: USB 5V and DC 18V Solar cells: Monocrystalline cells with a reported 24 percent increase in cell area or efficiency compared to prior versions Weight: 360 grams Dimensions: 360 x 330 x 2.5 mm Packing size: 455 x 375 x 35 mm Packing weight: 780 grams Installation and compatibility Pre drilled holes on the back allow for quick mounting and secure placement on flat surfaces or frames. Designed for integration with PWM charge controllers that offer multiple electrical protections, LCD display, and automatic 12V/24V system recognition. Can be wired in parallel or series depending on the desired system voltage and total power requirements. Performance note Under strong, direct sunlight and favorable conditions, a single 50W panel can produce roughly 500 Wh per day. Actual energy yield depends on sun angle, intensity, weather, and installation. With adequate sunlight, it can contribute to charging a 50 Ah battery in around 3 hours when used in an appropriate system setup; actual charge times vary with conditions. Typical applications RVs, caravans, and camper vans for charging batteries and powering small appliances. Boats and yachts for onboard electronics and battery maintenance. Off grid or backup setups for tents, cabins, and remote equipment. Golf carts or electric utility vehicles for supplemental charging. Notes and care Position the panel outdoors in direct sunlight and adjust tilt for exposure to maximize conversion efficiency. Keep the junction box dry. Clean the glass surface periodically to maintain output.
