Bachelor using air by using solar-degree angle under the sun to reduce the electricity consumption is to study the efficiency of electricity production of solar cells in order to adjust the angle. According to the Sun Using dc motor, 12 volt sensors measure the intensity of light in order to make solar cells based on the sun angle. The energy available to the wastewater treatment system that can be used in areas where no electricity is available. To create inventions To build a solar panel can adjust the angle as the sun itself, without the need to rotate the solar panel. And can produce more electricity than solar cells with that.
