  • Experimental And Theoretical Estimation Of Hourly Based Solar Irradiance In Baghdad
  • ABSTRACT: -In this work, the solar irradiance components were calculated
    theoretically using a program based on the theory that presented by ASHRAE standard
    based on latitude 32.2 in Baghdad. Solar irradiance components (Direct normal,
    diffused direct normal radiation and reradation) were measured practically except the
    last one at Baghdad using asolar power meter. Theoretically, the created program that
    based on the theory that presented by ASHRAE standard on latitude 32.2 in Baghdad
    can calculate hourly based direct normal, diffused direct normal and their sum for any
    day through the year with atime step of 15 min, assumed the local time was converted
    to solar time based on ASHRAE. A good nearby result were obtained between
    theoretical and practical data for the two solar irradiance components which confirm the
    used theory and experimental setup
