Evaluation of solar tracking systems applied to small-scale photovoltaic systems: a review

Abstract

This work evaluates solar tracking systems in application to small-scale photovoltaic systems. To do this, these systems are divided into two subsystems: one-axis solar tracking subsystem and two-axis solar tracking subsystem. Each is explored for its suitability as a suitable technology for small-scale application, defined by meeting a set of seven attributes. A specialized literature review process was developed specifically to present the potential of each subsystem evaluated, through an evaluation matrix. The analysis of solar tracking technologies and attributes was carried out through the formal concept analysis methodology. To facilitate the processing of information, a free access tool called concept Explorer is used. The analysis carried out shows that two-axis solar tracking systems are the most promising option as they meet a greater number of attributes than single-axis tracking systems. The applied methodology has proven to be useful for the evaluation of renewable technologies and serves as a reference, to carry out analyzes that group and link different alternatives as a model for evaluating a deterministic set of attributes.

LEESOLA: A Locally Made Energy Efficient Solar Tracking System for Home Use

“…I.E. Nwankwo et al [10] developed an intelligent solar tracking system and C. L. Sandoval-Rodriguez et al [11] analyzed the application of solar tracking systems for small-scale photovoltaic systems. Based on seven defined attributes, the study in [11] compares the suitability of single-axis and dual-axis solar tracking subsystems.…”
