Sun Position Calculator Function Block
(dwOPTION -29)

The Solar Function Block Library provides precise calculation of the sun zenith and azimuth angles in solar energy systems. It can be synchronized with the SNTP server time and date and include a ∂T input parameter to compensate for the difference between UTC and Terrestrial Time for precise positioning of solar concentrators.

Key Features:

  • Set up for any latitude, longitude and altitude.
  • Fast calculation for use in mobile systems.
  • SNTP synchronization support.
  • Terrestrial Time correction input.
