The downside of this unit is that if you try to use the rack that they give you for mounting, it will have to sit on the ground in a place that would be temporary. The wind could easily knock over the panels. There are no instructions in the package to mount the panels permanently and calling the support number got me nowhere. After considerable thought and experimentation, I have come up with a solution that works. The purpose of this instructable is show how I did it.
The goal was to mount the solar panels to the roof of a shed out in a country garden which does not have electrical power. The system would generally be used to charge battery-operated tools but other AC tools could probably be used via an inverter.
