Low cost two-axis solar tracker with high precision positioning

摘要

In this paper, the design of a low cost two-axis solar tracker is introduced. The aim is to obtain a high precision positioning of the cell. The control-board is able to support different control strategy such as classical techniques as PID algorithm or more advanced strategy such as fuzzy logic control (FLC). Using the error signal, the tracking capacities of the proposed approaches can be tested experimentally on the experimental prototype built in our laboratory.
