Something similar has been done with absorption chiller systems. The heat source used was evacuated tube thermal solar collectors - they're so effective at gather solar heat that they even work on cloudy days (Dewar bottles for the effin' win, yo). While the absorption chiller system isn't the most efficient in the world, the evacuated tubes should provide ample enough heat that such a system can build up an ice bank during the daylight hours for night time cooling.
You'll still need a power source to run the pumps and fans, but with the solar-fired absorption chiller system doing the hard work of actually cooling, a couple of solar cells and batteries with an automatic charger should be able to do that quite handily. Though if you don't use DC motors, you'll need an inverter, too.
This isn't a new idea, either. It's been around for a while if the publication date on this report to the US Dept of Energy is to be believed.
