We are told that Solakool air conditioning systems can save upto 80% electricity costs,so far we have not talked about any efficiencies that maybe obtained by a improved Delta-T due to solar induced compression/pressures and resulting increase in temperature,i.e difference of output air and input over the heat exchanger,we know we get a earlier condensation of refrigerant. Its one for the experts to comment

I do know that for every 1 degree increase in Delta-T usually means 4% increase in efficiency of cooling effect. That is more BTU.s of cooling for same electric energy .
