Plug into the sun
Keep your devices powered up when you're off the grid.
The Boulder 15 solar panel collects up to 15 watts of power from the sun, which you can store in one of Goal Zero's portable battery power packs. (The panel collects energy but it can't store it.)
Constructed from strong tempered glass, with a lightweight aluminum frame, the Boulder 15 panel can be easily carried or installed. Its weather-resistant design means the panel can be left outside when not in use. Common uses include RV, cabin, camping, trickle charging, or for recharging your power pack to power all your portable devices.
