Description:
Abstract: Monthly and annual average solar resource potential for
Alaska.
Purpose:
Provide information on the solar resource potential for
Alaska. The insolation values represent the average
solar energy available to a flat plate collector, such as a photovoltaic panel,
oriented due south at an angle from horizontal equal to the latitude of the
collector location.
Supplemental_Information:
This data provides monthly average and annual average daily
total solar resource averaged over surface cells of approximatley
40 km by 40 km in size. This data was developed from the Climatological
Solar Radiation (CSR) Model. The CSR model was developed by the National
Renewable Energy Laboratory for the U.S. Department of Energy. Specific
information about this model can be found in Maxwell, George and Wilcox (1998)
and George and Maxwell (1999). This model uses information on cloud cover, atmostpheric water vapor and trace gases, and the amount of
aerosols in the atmosphere to calculate the monthly average daily total insolation (sun and sky) falling on a horizontal surface.
The cloud cover data used as input to the CSR model are an
7-year histogram (1985-1991) of monthly average cloud fraction provided for
grid cells of approximately 40km x 40km in size. Thus, the spatial resolution
of the CSR model output is defined by this database. The data are obtained from
the National Climatic Data Center in Ashville, North Carolina, and were
developed from the U.S. Air Force Real Time Nephanalysis
(RTNEPH) program. Atmospheric water vapor, trace gases, and aerosols are
derived from a variety of sources. The procedures for converting the collector
at latitude tilt are described in Marion and Wilcox (1994). Where possible,
existing ground measurement stations are used to validate the data.
Nevertheless, there is uncertainty associated with the meterological
input to the model, since some of the input parameters are not avalible at a 40km resolution. As a result, it is believed
that the modeled values are accurate to approximately 10% of a true measured
value within the grid cell. Due to terrain effects and other micoclimate influences, the local cloud cover can vary
significantly even within a single grid cell. Furthermore, the uncertainty of the modeled estimates increase with distance
from reliable measurement sources and with the complexity of the terrain. Units
are in watt hours.
