Abstract: A shade cover or “solar fly” is provided for reducing the thermal radiation effects of the sun on an associated shelter. By blocking the sun's rays to a significant degree, the outer surface temperature of an associated shelter is reduced, which results in less heat transfer into the interior space thereof.

Natural convection known as the chimney effect may be used to reduce heat transfer into the interior space of the associated shelter. Such reduction of heat transfer into the interior space reduces the air conditioning load needed to maintain the interior space of the associated shelter at ambient temperatures of, for example, 76-84 degrees Fahrenheit among others.
