Design, Development and Control of Dual-Axis Solar Tracking System

A tremendous number of solar tracking systems are available in the market, no design however offers a fully autonomous operation that could track the sun with no prior information about the location, or the season. The proposed paper presents a design, development and control of dual-axes solar tracking systems. The tracking system consists of two DC-motor for two different axes, the incidence and declination angles, and a set of solar sensors. A set of sensors is employed to acquire the required data to compute the optimum zenith and azimuth angles. The advantage of the proposed that it can be used anywhere with no information needed regarding latitude nor longitude coordinates. The experimental results show a significant improving, like 76%, of performance obtained using dual axes tracking system compared with the fixed horizontal surfaces in the summer in Jordan, and 41% in winter.
