Is there any company which builds a solar powered Air conditioning / refrigeration system?
Answer:
A quick google search found the SolaCool evaporative system (link below) but an evaporative system isn't always viable in a very humid climate. Essentially, any a/c system is "solar powered" if you have a photovoltaic system installed in your home. In effect, solar power works best at the time of day when you most need a/c.
With net metering you don't need a bank of batteries to benefit from solar power.
The best solution is to design the architecture of a building to use natural convection currents caused by sunshine, but most existing homes are not that way. I have seen some great designs in Arizona that do this.
I do not know of any that make a solar power A/C unit. However, I do run a 5000 BTU unit from 800 watts in solar modules.
