This is the Powerfilm R28 flexible thin film solar panel. It is waterproof, lightweight, flexible, and will produce more power over the course of any day than any other 28 Watt solar panel on the market. Period. Why? Because Powerfilm is more sensitive than crystalline, it reaches threshold voltage & starts charging your battery pack earlier in the day, and stay charging later in the afternoon. This bigger bell curve of power means that you get more watt-hours of power, with faster deployment, and easier packing than any crystalline solar panel solution.
PowerFilm rollable, flexible solar panels are among the toughest thin-film portable solar panels available today. They are your best option for boats, kayaks, or any other activity where your solar equipment will be exposed to wet, or especially harsh environments. They are designed for users who need lightweight portable & remote power for laptops, cell phones, satellite phones, GPS units, & other. PowerFilm are about as thick as an ordinary canvas tarp, and almost as pliable! PowerFilm solar panels offer the best chemistry for off-season use and higher latitudes due to excellent solar panel sensitivity in low-light & partial shade.

PowerFilm solar panels are monolithically integrated which means they are manufactured in layers. This eliminates the need for damage-prone manual connections of individual solar cells. PowerFilm flexible solar panels are made using amorphous silicon, and are naturally free from harmful heavy metals like cadmium that are used in other technologies.
Originally designed for military use, PowerFilm panels perform well in diverse conditions such as hot sun, and partial shade. They come ready to connect to batteries and an array of handy accessories using marine-grade plug and play connectors. Rugged corner grommets are provided for tying the panels to boat decks, backpacks, tents, and more. Portable solar power has never been more convenient!
Choose from 7, 14, 21, or 28 Watt output panels in the rollable line. These outputs are provided at 15.4V, which is great for charging all types of battery packs.
