Often we're asked, what makes our Packr™ Executive Solar Backpacks so flexible and rugged? We tell them it's the CIGS solar technology
they're made with. While most solar, like monocrystalline & polycrystalline cells are placed on a glass substrate which makes the units extremely heavy, rigid, and very susceptible to breakable, CIGS solar on the other hand has the ability to be placed on a plastic backing. This allows our solar chargers/panels to be EXTREMELY LIGHT, RUGGED AND FLEXIBLE. And this technology is patented so only EnerPlex® sells these panels because our parent company Ascent Solar
® makes them, and best of all they're made here in the USA.
