A quantitative study of the systematic and accidental errors that affect solar-altitude azimuths shows that the precision of azimuths can be increased materially by taking into account the systematic errors due to curvature and semidiameter. When this is done, the elapsed time of an observation ma...
(Badaling), in its heliostat tracking control programs, applied a solar position algorithm proposed by Roberto Grena that considers both precision calculation and time consumption calculation, and solar position precision fell within a range of 0.0027 degrees; solar altitude and azimuth angle at present...
The unit features an uninterruptable power supply and sensors for air temperature, relative humidity, diffuse radiation, total global plane of array irradiation, total global horizontal irradiation, solar altitude and azimuth angle, precipitation, and back of module temperature. Hands-off testing key ...
4.1.5. Solar Altitude and Azimuth Angle Tests are to be conducted between 10 : 00 hrs and 14 : 00 hrs solar time, because solar zenith angle is somewhat constant at midday, and the difference between the insolation perpendicular to direct beam radiation will be very less. ...
20): solar altitude and solar azimuth. Sign in to download full-size image Figure 20. Definition of angles used to describe the solar position (γs and αs), the orientation and tilt of the irradiated plane (α and β), the angle of incidence (ν), and the horizontal shadow angle (...

Solar altitude (γS) is the angular elevation of the center of the solar disk above the horizontal plane. • Solar azimuth (αS) is the horizontal angle between the vertical plane containing the center of the solar disk and the vertical plane running in a true north–south direction. It...
whereIBΣis calculated using direct beam radiation on horizonal surface (IBH) and solar incidence angle (θ0). Theθ0is estimated by taking into account solar altitude angle, solar azimuth angle, solar hour angle, solar panel azimuth angle, and solar panel tilt angle based upon dual-axis tra...
