Whether they make sense or not depends on how cheaply you can acquire them, and what you plan to do with them. My standard frame of reference is polycrystalline UL listed panels with frames and boxes for $0.72/W from reputable dealers, with roughly a $500 delivery charge (on a pallet, shipped California to South Florida).
Are these laminates UL listed? Building a grid-tied system usually requires UL listings on all the major components. If you're simply building an off-grid solar shed in the backyard, UL may not be required. (unless you open pandora's box with an insurance company about something having to do with the PV system).
