The EcoFlow Portable Solar Panel helps power your everyday appliances at home and off-grid with sustainable solar energy. Two-in-One Bifacial Design â EcoFlow's 220W Bifacial Portable Solar Panel is two in one. With a 220W primary side and a 155W side on the back for ambient light, you can capture up to 25% more solar energy and charge your portable power station even faster. Built to Last â The thin, one-piece tempered glass design makes it five times tougher than comparable panels with half the thickness of traditional tempered glass. Capable of withstanding heat up to 300°F, it's safe to say it can resist the elements. Offers 4 times more rear side heat dissipation and less than 10% power degradation over 10 years. Powerfully Portable â It's a portable solar panel designed from the ground up to be compact. 10% smaller than comparable 220W panels, it saves space with thinner tempered glass and less surface area required for the same input. More than a Carry Case â It comes with its own carry case so you can take it anywhere. Once you arrive at your destination, simply unfold it and use it as a kickstand to get your sun exposure just right. Waterproof Too â This panel is completely water and dust-tight. Rain, wind, or shine, your panel is safe with an IP68 waterproof rating.
