Iowa, solar radiation, insolation
Historical records spanning over 20 years have been analyzed to determine the long-term monthly average daily solar radiation falling on a horizontal surface in Ames, Iowa. This value has been used to estimate the long-term monthly average daily solar radiation falling on surfaces of other tilts (30°, 60°, and 90° relative to the horizontal) and orientations (at 30° intervals from south to north). Some important features of the results are described. A BASIC computer program is available which can be used to estimate the solar radiation on a surface of arbitrary tilt and orientation.
