Introduction to Solar PV Cooling and Comparison with Alternatives

The use of solar photovoltaics (PV) to provide comfort cooling will be presented.  The cost of solar PV installations has fallen, making the solar electricity competitive.  This discussion will cover techniques to best apply solar PV energy to cooling loads.  The "total solar cooling efficiency" of different methods will be compared for both solar PV and solar thermal.  Specific applications, i.e., PV driven air conditioning and heat pumps, energy storage, load mismatch, and PV with energy efficiency, will be discussed.  The shading effect of roof mounted PV arrays on HVAC systems and building loads will also be discussed.
