AUTOMATIC BUILDING INTEGRATED SOLAR SHADE

Abstract

This paper presents an Automatic Building Integrated Solar Shade system (ABISS). It was discovered that solar radiation is prevented from getting into the buildings; with the solar blind tracking system would overcome the difficulties. ABISS is designed and developed in order to generate constant, reliable and efficient power supply.ABISS is designed using Proteus software to simulate behavior of the system (software and hardware design) before implementation. Furthermore, the ABISS is designed to track the position of the sun automatically in order to improve an efficient energy harvest. Light Dependent Resistors (LDRs) are used to detect the light intensity of the sun. Based on its signal, the Microcontroller (PIC18F4520) gives a signal to the motor driver to energize the unipolar stepper motor. This results in moving the integrated solar panel into rotational angles to track the position of the sun. This will lead to improve solar tracking system efficiency of the Photovoltaic (PV) while maintaining the orientation of the integrated PV at an optimal tilt angle. In addition, sleep mode is used to reduce energy consumption of the Microcontroller. The Microcontroller resumes operation caused by an external interrupt from a Real Time Clock (RTC) after 15 minutes of sleep. The embedded code is developed by using C language; in order to achieve the all functions of the ABISS design .The paper also investigates the effect of the solar shading system, using the appropriate technique of a solar tracking system.
