I recall reading research into running absorbtion using alcohol instead of ammonia.
----------
Given a phase change media, one ought to get it "cool" during sunshine hours to use after. Thus solar absorbtion, certainly via ammonia systems, are possible for whatever. My workplace uses 3 tanks of media which they charge up cold during the night, then don't run the AC condensers during the day. 1/3 the cost for the electric I think.
So...solar could do the job, without ammonia, but you need a tank to hold the phase change media.

Home energy loads are high for heating, hot water and air cooling. But these can be done via solar, IMHO. Someday they will, but I'm not in favor of gov't intervention.
Sadly some think that home energy usage is the gross energy burden. They promote gov't regulation and advertising to fix the problem. But a quick review of energy usage shows that an advanced country producing a significant GDP uses most of it's energy in Industry, energy distribution (50% loss for electric) and transport.
See LLNL energy flow chart
But that doesn't sell well so we have govt policy "buy soma, buy compact flourescent, buy soma soma soma, be efficient, be happy, etc etc. Please ignore the sunspot cycle, trade carbon...."
