Аннотация

Modern solar follow-up systems make it possible to increase a solar cell’s efficiency and, as a result, solar energy utilization. The paper considers modern solar follow-up methods and their operational principles. Trackers are separated onto uniaxial and biaxial according to the plane which tracking occurs. Biaxial trackers are the most efficient. The operational principles of active and passive trackers are studied. A laboratory model of a biaxial solar tracker with precise solar orientation is described, based on an algorithm for calculating the voltage with current sensors. The following are given in the paper: the current–voltage characteristic obtained for different solar array positions and using trackers; the relationships between the power and measured currents and voltages. The efficiency is calculated for different solar array positions and using a tracker.
