A Solar Power Regulation System Equipped with Intelligent Solar Power Detector

Abstract

This paper describes a solar energy power regulation system using solar power detectors. The system developed comprises a cubic solar power detector, DC-DC converter, three-phase inverter, and a single-chip control module. The cubic solar power detector is composed of five facets installed with front, rear, left, right, and horizontal photo sensors. By detecting solar power coming from different orientations, the solar orientation and solar power can be optimized based on a geometric transformation principle, which evaluates the relationship between photo-power and solar orientation for each sensor. Because the output power of a solar cell can significantly affect the generating capacity of the cell, a solar energy power regulation system was developed to regulate the electricity generated. The solar generating power is monitored by a cubic solar power detector and regulated by a three-phase pulse width modulation inverter. This paper describes the realization and implementation of a solar power regulation system, and experiments have been carried out to validate the performance. Measurements reveal that the system is definitely effective in regulating solar power output and can successfully boost solar power generating capacity.
