Can this model be daisy-chained?

I got two of these in my recent purchase. One with the 150 Escape kit and another extra to have and combine two panels for 60w of power. I bought the Briefcase model as I wanted a mobile panel that was protected in travel. Also the built in prop stands are important. The other Boulder 15w and 30w panels look fine, but they would have to be mounted somehow or propped up on ground, and also you would have to have a protective travel case. The Escape panel has all of that built in and I setup on roof of my small trailer without any issues, as the design allows the panel to be self standing and secure. You can also run a security cable thur the handles of the sturdy case to secure the panels to your RV when you are not home so they do not easily be grabbed by someone. The built in output cord is about 9 ft long so an extension cord may not be needed. Only potential issue I can see is the plastic hook thingies that keep the case closed look to be a bit likely to break down the road. otherwise a great panel for camping RV use in basecamp.
