This was my senior team project in engineering school, in 1974. Here were our findings:
The power needed to run a small absorption refrigerator can be supplied by a solar collector of about 32 square feet, but the temperature required to boil the ammonia out of the water requires a concentrating collector (not a flat plate)- and hence requires an aiming ...

It is a lot more efficient to convert the solar to electricity and run a decent heat pump for AC and normal refrigeration. Absorption refrigeration is expensive, bulky, not terribly versatile, and has poor thermal efficiency.
The Coefficient of Performance of a large single stage absorption chiller is about 0.7.
The conversion efficiency of solar electric vs ...
