Design and fabrication of a parabolic solar water desalination system

The solar energy as renewable energy resources for desalination of water is novel, since it allows the daily use of renewable resources existed. Three phases are employed for desalination process. The first phase is preheating the pumped seawater, this is followed by steam generation phase by means of parabolic dish or trough collectors. The third phase is the condensation phase. An automatic sun tracking system is attached to parabolic dish or trough collector to increase the efficiency of solar energy collected during the day. Preliminary calculations suggest that the system could provide a temperature of 315 °C at least during the day with about 0.06 L/s of soft water, using parabolic dish of 4 m2 surface area. Solar thermal energy had previously only be used in small-scale devices in rural regions for sea water desalination. The reason for this has mainly been explained by the relatively low productivity rate compared to the high capital cost. However, the coming shortage in fossil fuel supply and the growing need for fresh water in order to support increasing water and irrigation needs, have motivated further development of water desalination and purification by renewable energies.

Single Axis Solar Tracker for Maximizing Power Production and Sunlight Overlapping Removal on the Sensors of Tracker

This paper presents the design and execution of a solar tracker system devoted to photovoltaic (PV) conversion panels. The proposed single-axis solar tracker is shifted automatically based on the sunlight detector or tracking sensor. This system also removes incident sunlight overlapping from sensors that are inside the sunlight tracking system. The Light Dependent Resistor (LDR) is used as a sensor to sense the intensity of light accurately. The sensors are placed at a certain distance from each other in the tracker system to avoid sunlight overlapping for maximum power production. The total system is designed by using a microcontroller (PIC16F877A) as a brain to control the whole system. The solar panel converts sunlight into electricity. The PV panel is fixed with a vertical axis of the tracker. This microcontroller will compare the data and rotate a solar panel via a stepper motor in the right direction to collect maximum photon energy from sunlight. From the experimental results, it can be determined that the automatic (PV solar tracker) sun tracking system is 72.45% more efficient than fixed panels, where the output power of the fixed panel and automatically adjusted panel are 8.289 watts and 14.287 watts, respectively.

Solar Tracker: A Review

A solar tracker is a traditional term used to describe devices that coordinate or align different payloads with the sun. The aim of the automatic sun tracking system is to retain the photovoltaic solar panel perpendicular to the sun throughout the year to make it more efficient. A solar power transforms sunlight into electricity. This automated sun tracking system helps generate power by automatically tuning the device for optimum sunlight. Through reducing light intensity, this system will automatically change its direction to reach maximum amount of light. Light intensity is the big problem with solar power generation. To produce the maximum energy, a solar panel must be upright and face-to-face with the light source. Because the sun moves all through the day as well as throughout the year, in order to produce as much energy as possible, a solar panel must be able to follow the sun’s movement. The approach is to use a light source tracking system to preserve the panel’s orthogonal location. Several tracking systems models exist, including passive and active systems with one or two freedom axes. Solar trackers are used with different sensors to dramatically increase the electrical power of the photovoltaic panel. Photovoltaic systems are rapidly becoming a fresh source of energy by capturing the solar radiation. Optimizing its power output is desirable in order to increase its efficiency. The panels must be aligned with the sun in order to optimize the power output of solar panels. It has been estimated that energy derived from solar panels can be expanded by 20 to 30% by using a tracking system instead of a stationary array. Over time, different approaches have been developed. Astronomical or time-based systems are the most popular, and then optical approaches are used to align the PV components with different image sensor types.

Design of Two-Axis Automatic Sun Tracking System Assisted with Manual Control through LabVIEW

With the fast depletion of the conventional energy resources and the amount of pollution it is creating, the entire world is looking for an alternative non-conventional and a renewable energy to lessen the dependency on the conventional energy resources. In this scenario, utilizing solar energy which is abundant in nature is gaining high attention. One way of utilizing solar energy is by using solar photovoltaic cells which convert light energy into electrical energy, but they are too costly and less efficient. Many techniques are being developed to reduce the cost and improve the efficiency in harnessing solar energy. Sun tracking technique is one of the methods to increase the efficiency of solar cells. The present work is focused on providing a microcontroller based automatic two-axis sun tracker using Photodiodes as sensors to track sun. The system is assisted with a manual control through LabVIEW (Graphical User friendly Interface) to aid during bad weather conditions.

This temperature is suitable for cooking purposes and this was achieved by using the two axes sun tracking system.

CONSTRUCTION OF AN E-CALLISTO STATION IN KOREA

The e-CALLISTO is a global network of frequency-agile solar radio spectrometers that was constructed in a collaboration between Swiss Federal Institute of Technology Zurich (ETH Zurich) and local host institutes. It is intended to monitor solar radio bursts 24 hours a day in frequency range between 45 MHz and 870 MHz. One of e-CALLISTO spectrometer was installed at Korea Astronomy and Space Science Institute (KASI) in 2007 October. The spectrometer gets signals from a horizontally polarized log-periodic antenna mounted on an automatic Sun-tracking system. Tracking status and data are monitored in Space Weather Monitoring Laboratory (SWML) of KASI in real time, and flare time data are transferred to ETH Zurich data archive daily. Using this spectrometer we obtained a couple of type II solar radio bursts on 2007 December 31, and found that these bursts are associated with a CME which occurred on the east limb.

A microprocessor controlled automatic sun tracker

A microprocessor-based automatic sun-tracking system is proposed. This unit controls the movement of a solar panel that rotates and follows the motion of the sun. There are two limit switches attached to the panel to mark its maximum angular positions in the east and west. The status of the limit switches is read by the microprocessor and indicates that the maximum angular position in either direction has been reached and the panel should not be driven any further. As the plane of the panel is always kept normal to the direction of the sun, maximum thermal energy is obtained from the solar panels. >
