The data presented on the data pages in this manual, with the exception of the solar radiation graph, are available in ASCII format for downloading. These data can be imported into popular spreadsheet
programs. Also available are averages of solar radiation for each of the flat-plate and concentrating collectors for each month during the period of 1961-1990 (360 months). These data could be useful
for identifying extended periods of low or high solar radiation or plotting graphs of monthly solar radiation for any of the flat-plate and concentrating collectors. The printed manual includes graphs
only for flat-plate collectors tilted at an angle equal to the latitude.
