Xunlight XRD36-300 300W 58V Amorphous Flexible Solar Panel SolarLok RV

Xunlight XRD36-300 300W 58V Amorphous Flexible Solar Panel SolarLok RV

The Xunlight XRD36-300 is a 300-watt amorphous silicon flexible solar panel built on a stainless steel substrate and encapsulated in EVA and ETFE — a construction that makes the panel both highly flexible and exceptionally durable. At 203 inches long by 35 inches wide, it unrolls flat onto any curved or irregular surface, making it well suited for RV roofs, boat decks, and off-grid installations where a rigid glass panel cannot be mounted. These panels were manufactured at Xunlight Corporation's facility in Toledo, Ohio between 2012 and 2015. Xunlight has since closed, and this stock represents the remaining inventory of these panels.

Applications

Amorphous silicon flexible solar panels like the XRD36-300 are used in applications where a rigid, glass-faced module is impractical — most commonly on curved RV rooftops, boat and yacht decks, truck cab roofs, and portable off-grid power systems. Unlike crystalline silicon panels, amorphous thin-film cells perform better in diffuse and low-angle light conditions, which can be an advantage in overcast climates or on surfaces that are not optimally tilted toward the sun. The stainless steel substrate and ETFE top surface make the panel resistant to impact, vibration, and moisture — practical for mobile installations. The SolarLok connector system is a Tyco-designed locking solar connector; adapters to MC4 are available from Tyco and third-party suppliers, allowing connection to standard charge controllers and combiner boxes. These panels are recommended for battery charging applications rather than grid-tied systems, and work with standard MPPT or PWM charge controllers sized for a 57.9V nominal input.
