“…The total daily Abu-Khader et al (2008) reportan un incremento global de alrededor de 30-45% en la potencia de salida para el sistema de seguimiento solar en eje norte-sur (N-S), al comparar con un sistema FV fijo; mientras que Huang et al (2011) encontraron que en un día soleado un seguidor de un eje puede obtener 35.6% más de energía respecto a un sistema FV fijo; y Kacira et al (2004) encontraron que la ganancia promedio diaria es de 29.3% en la radiación solar y 34.6% en la generación de potencia para un día particular de julio en Sanliurfa Turquía de un seguidor solar de dos ejes respecto a un panel FV fijo. Estos resultados son mayores a los resultados obtenidos en esta investigación, lo cual puede deberse a el lugar y la época del año, a que los dispositivos utilizados en la medición de corrientes y voltajes fueron diferentes, a los métodos de cálculo y debido a que los cálculos en el presente trabajo tomaron en cuenta un factor de corrección por temperatura (SEI, 2007).…”

“…(SEI, 2007). Abu-Khader et al (2008) reported an overall increase of about 30-45% in power output for solar tracking system in northsouth axis (NS), when compared to a fixed PV system; while Huang et al (2011) found that on a sunny day, a tracker of an axis can get 35.6% more energy relative to a fixed PV system; and Kacira et al (2004) found that, the average daily gain is 29.3% in solar radiation and 34.6% in power generation for a particular July day in Sanliurfa Turkey of a solar tracker with two axes relative to a fixed PV panel. These results are higher than the results obtained in this research, which may be due to the location and time of year, the devices used for measuring the flows and voltages, as well as the different methods of calculation, since calculations in this study took into account a correction for temperature (SEI, 2007).…”

“…La incidencia de radiación solar en la región es en promedio de 5.5 kWh m -² día -1 (Castellanos y Escobedo, 1980;SEI, 2007). Abu-Khader et al (2008) reported an overall increase of about 30-45% in power output for solar tracking system in north-south axis (NS), compared with a fixed PV system; also they found that the solar tracking the NS axis is optimal.

Entre las fuentes de energías renovables, la energía solar es la más importante, debido a su abundancia, sostenibilidad y completamente libre de costo. Además utilizando un colector solar con seguimiento, la energía total recibida en un día claro puede ser del orden de un 30-45% mayor que para el mismo colector solar estático. Se diseñó y construyó un sistema de seguimiento autónomo y capaz de seguir el movimiento de sol, el cual se acoplo a un panel fotovoltaico para mejorar la ef iciencia en la captura de energía. Se evaluó el funcionamiento del dispositivo en términos energéticos, se realizaron tres pruebas de evaluación programándolo para que se oriente al sol a cada 60, 30 y 5 min, y se compararon los resultados con el rendimiento energético de un panel fotovoltaico f ijo. El software desarrollado fue funcional para la totalidad del territorio de la República Mexicana y durante todo el año. El mejor rendimiento energético se obtuvo cuando el seguidor solar se orientó al sol cada 60 min, la energía generada fue de 27.98% más respecto al panel fijo, con un gasto energético para su funcionamiento de 1.3% de la ganancia final de energía. Comparando la producción de energía del sistema con la radiación solar global (ISR, por sus siglas en ingles), éste aprovecho 13.27% de la energía disponible, y 2.93% más respecto al panel fijo.

“…In the second way, which is to track the sun, and hence change the angles, provides a higher electricity generation efficiency as the income angle can be more perpendicular [4]. The tracking system can be a single axis, changing only one angle, [5], [6], [7], or multi-axis, which changes both angles [8]. The control of the motors which change the angles can be open loop [9], in which a look-up table is used, or closed loop [10], [11], [12].…”

Turkish government has increased the importance of Konya-Karapınar region by making the area a pilot region for solar energy production. In the near future, the government plans to have a 1 GW solar energy plant in the area. According to this master plan, a pilot solar energy production system was established in the Necmettin Erbakan University campus. A 1000W two-axis tracking and 1000W fixed panels were implemented in this system. In this paper, the performance of these panels are compared and evaluated. 25 years of solar radiation data for Konya is taken from the state meteorology institute, and the produced energy is compared with the predicted values. Tracking panels are found to be approximately 25% more efficient than the fixed panels. However, the maintenance of the tracking panels is observed to be more costly. Moreover periodic cleaning and repairs are found to be very important and another cost factor for both systems. Using the insight from this pilot system, an economic analysis of a large scale 1MW solar energy plant to be established in the campus is performed. For this analysis, fixed panels are considered due to the low investment and maintenance costs and the simplicity of the maintenance work. It is found that the 1MW solar plant will recover the investment cost within 4-5 years and will provide almost 3M$ profit after 20 years.

Summary In this paper, an attempt has been made to develop a two‐axis tracking system for solar parabolic dish concentrator and experimentally evaluated the performance of the tracking system. In this proposed design, the sensor design uses the illumination produced by the convex lens on the apex of a pyramid to align the dish in‐line with the sun. The change in incident angle of the solar rays on the lens surface shifts the area of illumination from the apex of the pyramid towards its faces. Photodiodes placed on the faces of the pyramid are used as the sensitive elements to detect the movement of the sun. The sensor output is fed to a microcontroller‐based system to drive the stepper motor on the basis of the programmed algorithm such that it receives normal incidence of sunlight on the sensor. To evaluate the performance of the proposed system, a conventional available 1‐W photovoltaic (PV) panel is placed at the focal point to measure the short circuit current and open circuit voltage. With respect to the conventional solar PV panel, it is observed that the positioning accuracy of the proposed tracking system enhances the short circuit current of 0.11 A by 86%. Thus, the proposed tracking system can be used in a stand‐alone parabolic dish with concentrating PV module as the focal point for further studies.
