PowerFilm Rollable Solar Panels
PowerFilm Rollable Solar Panels are perfect for keeping your batteries topped off when operating portable, or for any activity where you want to keep batteries charged without the noise of a generator. These rollable panels roll down to 3 inches in diameter for the panels that are 28 watts and smaller and 5 inches for the 42 and 60 watt panels. Small and compact, these rollable solar panels are a go to for supplying power in places where power is sometimes hard to find. Grommets on the corners of the panel help secure it in place, prevent damage in high winds. These high tech thin and flexible panels continue to produce power even when damaged. They generate electricity in cloudy, shady, and hazy environments and outperform other solar panels in low-light environments. A charge controller is not required if the battery capacity is 100x greater (or more) than the panel output. For example, a 100Ah battery would not need a charge controller if the panel output is 1A or less. If a charge controller is required, it should be sized according to the output of the panel. Available in a range of output wattages from 7 to 60 Watts there's sure to be an option to meet your specific needs. * Note: Part numbers ending in -NG are manufactured without grommets and will require something to hold them down.
