DUAL AXIS SOLAR POWER TRACKING SYSTEM

Dual-axis solar tracking is a promising technique for improving the orientation of photovoltaic panels toward the Sun. An Arduino Uno-based system using LDR sensors and suitable motors offers an affordable platform for demonstrating automatic solar tracking. Its performance must be verified through controlled measurements of energy generation and tracking-system consumption. Further improvements in control algorithms, mechanical design, and monitoring technology can enhance its reliability and practical usefulness.
