In this paper, various solar position parameters to estimate the solar position throughout the year at individual hours have been calculated. A stepwise procedure to calculate various solar parameters like declination angle, hour angle, solar elevation, solar azimuth angles, etc. has also been given. A north eastern city of India, Agartala with latitude 23.80 N and longitude 91.50 E has been chosen as the target location. The equation of time has been calculated in this paper which plays a major role in locating the sun’s position. An algorithm has been designed to calculate the solar parameter angles that specify the sun’s position at any location, at any instant of time. The variations of the respective angles that specify the sun’s position are also given graphically for a particular hour throughout the year.
