This is one of the most durable panels out there but it is way too expensive compared to other panels with just as much functionality for a fraction of the cost.
The Goal Zero Nomad 7 is almost as versatile as the 9 watt SolarRoll but is much more compact and $120-300 less expensive.
If you do want a system that lets you link multiple panels, the Goal Zero Sherpa 50 Adventure Kit or the Goal Zero Sherpa 120 Kit are the way to go. They give you much more value per watt AND an awesome battery to store the power.
If you want a 12-14 watt system that is as light as the SolarRoll 14, we would much rather have the Sunforce 12 Watt Solar Panel. It is less than half the cost of the SolarRool 14, lighter, and more compact.
