Abstract

The presented paper deals with the issue of the efficient use of solar energy potential gained from thermal panels via tracking the Sun’s trajectory. Based on long-term measurements of the selected parameters, the efficiency of the installed system in relation to the ecliptic was evaluated in the static regime as well as in a rotary regime. In the comparison of rotary and fixed system of the collectors the presented results show an increase of the effectiveness of rotary one during the period of the day. On closer view the increase is not constant. During the day it varies: the most significant increase is in the afternoon, while the time from 10:30 a.m. to 1:00 p.m. the effectiveness of both systems almost identical. The utilisation of the rotary system as a suitable instrument for the elimination of the system stagnation was also evaluated.
