• Principles of solar tacking system.
  • Solar calculation through:
    • Julian Day
    • Sun declination and sun light duration
    • Solar zenith and solar elevation angle in degrees.
    • Solar azimuth angle in degree clock wise from north.
  • Importance of true north

The IRE-272 is a hands-on solar tracking control trainer designed to help estimate the generation quantity in relation to solar altitude.  The IRE-272 can control the motor through PC interface aided by e-compass in any directions (top to bottom and left to right).
