Abstract

Measurement the outdoor efficiency of photovoltaic (PV) panels is essential, but it is not likely an exceptional circumstance at any given moment is always repeating itself. A solar simulator was designed and fabricated for the purpose of analyzing the performance of PV panel with and without an air cooling mechanism in indoor test. Twenty units of 500 W halogen lamps with build-in reflector support by the steel structure holder act as a natural sunlight. The uniformity of the solar radiation was measured in the test area. Two units of PV panel with same characteristics were experimental in three sets of uniformity of solar radiation, which are 620, 821 and 1016 W/m². The operating temperature of PV panel with an air cooling mechanism can be decreased 2-3 ˚C compared to PV panel reference. The PV panel with an air cooling mechanism can be increased in 3-7 % of maximum power output based on solar radiation. An overall method and procedure of the measurement by the solar simulator are discussed and proposed.

Abstract

The aim of this project is to investigate the performance of photovoltaic (PV) panel influence by wind speed in Kangar, Perlis, Malaysia. A low conversion energy efficiency of the PV panel is the major problem of a PV application system. The PV panel is absorbed solar irradiance minor converted into electrical energy, and the rest is converted into heat energy. Therefore, the heat energy generated by the PV panel is increased in its operating temperature. However, PV panel is necessary to operate them at the low operating temperatures to keep the PV panel electrical efficiency at an acceptable level. In this experiment, one unit of the PV panel was limited wind flow over its surface and the other one PV panel was operated in the normal condition. The operating temperature of the PV panel with wind speed is less than the PV panel without wind speed. This is due to wind flow over the surface of the PV panel can enhance heat extraction from the PV panel. Hence, PV panel with wind speed can generate a higher output power than that without wind speed. This improvement output performance of PV panel will have an important contribution to PV application systems.

Abstract

 The low conversion energy efficiency of solar panel is affected by the several environmental issues. Solar radiation, ambient temperature, dust accumulation and wind velocity are the environmental problems. This main goal of this paper is to understanding the solar panel behavior under varying of wind velocity amounts. A three-dimension (3-D) model of solar panel is conducted in the present investigation. The solar panel model is simulated under given operating condition and different amounts of wind velocity. Four different of wind velocity value of 0 m/s, 0.43 m/s, 2.5 m/s and 6.95 m/s was selected to examine the solar panel performance. The simulation results are obtained with ANSYS simulation software. The temperature distribution of the solar panel model will be discussed in this current paper. The simulation result is showed highest wind velocity can be provided good cooling effect for the solar panel model in order to enable the solar panel can be operated to perform well at lower temperature.

Abstract

Practical activities based on the latest science are rarely carried out because they are constrained by expensive equipment, one of which is solar cell technology. The use of conductive glass has become an interesting topic in recent technology. This technology can be implemented in photovoltaic cells (solar cells) and organic lightemitting diodes (OLED), which are very close to our current needs to face the energy crisis. This study aims to develop practical activities in a chemistry. laboratory for the manufacture of fluorine-doped Tin Oxide (FTO)-based surface conductive glass. This research was conducted using educational design research methods using the framework of the Model of Educational Reconstruction (MER). This research produces Transparent Conductive Glass FTO (Fluorine-doped Tin Oxide) with spray deposition technique / Spray Pyrolysis using a Bunsen burner, the result of optimization of some surface conductive glass with sheet resistance of about 1 – 10 kΩ. These results were obtained by applying ten times of SnO2.F deposition on the glass, three times of spraying, and a heating time of about five minutes at a temperature of 250 – 300 °C. This procedure is obtained using a simple laboratory apparatus such as a Bunsen burner, which is available in the Basic chemistry laboratory for applying NOST (Nature of Science and Technology).
