SOLAR PANEL SUN TRACKING DUAL AXIS WITH WEATHER SENSOR

Abstract

Abstract- This paper introduces a comprehensive system designed to enhance solar energy harvesting efficiency by continuously tracking the sun's position and monitoring environmental conditions. Through the utilization of solar geometry calculations implemented in Arduino programming, the system accurately determines Solar Azimuth Angle and Solar Elevation Angle in real time. By integrating this data with user-provided latitude and longitude values, three servo motors are controlled to align a solar panel perpendicular to the sun's rays, maximizing energy capture throughout the year. Additionally, temperature sensors enable ambient temperature monitoring, while voltage and current sensors measure power generation from the solar panel. Data on energy generation and temperature readings are transmitted to the user's ThingSpeak IoT Analytics Platform dashboard via a WiFi module for real-time monitoring, and also displayed on an LCD screen. This comprehensive solution offers insights into solar energy harvesting and environmental conditions, demonstrating its potential for sustainable energy applications in both residential and non-residential settings.
