Why limit yourself to a solar panel that just doesn't cut it? With ATEM POWER's shingled folding solar panels, you don't have to compromise on portability, efficiency, or style. Our shingled cell technology is tailored to meet the needs of all solar power users, delivering unbeatable performance and sleek aesthetics. With the shingled cell technology, this 300W solar panel offers pure cell exposure to sunlight with no interruptions. By eliminating the need for ribbons, busbars, and soldering processes, the shingled solar panel offers 15~20% more output than traditional panels, significantly reducing energy losses and hot spots. Our ETFE tech also maximizes light penetration. The result? A solar panel that's not only powerful but also incredibly efficient. With the MPPT controller, you'll get 20% more energy than a PWM controller. Plus, our foldable design with an IP-65 rating mean you can take it wherever you go. Power up wherever, whenever with our shingled foldable solar panel! Features Shingled Cell Tech: Get more energy from the sun with shingled cell tech that uses a string of strips instead of ribbons and busbars for maximum energy output. Built to Last: Our shingled flexible solar panel offer improved reliability and durability, able to withstand external forces that cause failure in conventional panels. Maximum Efficiency: Our shingled cells wired in parallel minimize energy losses and the hotspots caused by shade, ensuring optimal energy output. Higher Output: Get 15-20% more output than traditional panels with our electrically conductive adhesive (ECA) technology that joins our panels together. Waterproof & Rugged: With a robust aluminium frame and an impressive IP-65 waterproof rating, our panel will keep working whatever the weather throws at it. Upgraded MPPT: The MPPT controller stands out for ability to wake up sleeping lithium batteries, and works with lead-acid, AGM, GEL, flooded, and lithium batteries. Subversive ETFE Tech: Our solar panel use ETFE technology, allowing for higher light penetration, excellent flexibility, and more heat resistance than PET films. Wide-ranging Suitability: Our flexible solar panel work seamlessly with a wide range of batteries and perfect for 4WDs, utes, caravans, camper trailers, and boats. Aesthetically Superior: Our 300W shingled flexible solar panel boast a clean, simple, and sleek design that is as visually appealing as it is functional. Optimally Designed: Our kickstands maximize power harvesting, magnetic design makes it easy to unfold and fold, and the carry bag invites more portability.
