R21 21 Watt Rollable Solar Panel
PowerFilm Rollable solar panels are thin, lightweight, flexible and can withstand extreme environments to reliably provide power where you need it.


The PowerFilm R21 21 Watt Rollable Solar Panel is the perfect portable solar solution for waterlogged environments when you need to keep small electronics powered-up, or you want to supply a trickle charge to the battery of a boat without worrying about water. This is a great solution for boating, camping, or charging a 12V battery from solar in remote areas. Unlike other thin-film solar technologies, PowerFilm solar chargers do not need to be "sun soaked" after storage to produce peak power; you have critical power to moment you need it.

Using the R21 rollable solar panel:

Simply unroll the solar panel with the solar material facing towards the sun.
Power your device or charge your 12V battery by connecting to the solar panel using the female car charger adapter (RA-2) or 15' cord with O-ring connectors (both included).
Consider options to protect the battery from overcharging such as the 4.5 Amp Charge Controller (RA-9) which protects 12V lead acid batteries.
