ABSTRACT

Solar tracking drives can be broadly classified as active or passive. Passive drives are mechanical
while active drives are electrical. In this paper, a review of the most recent (2015 -2019)
published techniques for photovoltaic tracking drives is presented. Based on functionality and
results, the published techniques are presented. Active drives are shown to be more efficient
when compared with the passive drives. However, in terms of flexibility and cost, passive drives
are more viable than active drives. The advantages and disadvantages of each drive is given as a
conclusion
