Dual Axis Solar Tracker: Maximizing Solar Energy Harvesting
Solar energy is one of the most promising renewable energy sources which can help reduce dependence on conventional sources of energy and mitigate environmental issues associated with them.

Working of a Dual Axis Solar Tracker:
A dual axis solar tracker relies on sensors, microcontrollers and actuators for its functioning. Light-sensitive sensors are commonly used to detect the location of the sun and position the panels perpendicular to incoming sunlight.
Microcontrollers receive input from sensors and send signals to actuators such as stepper motors to alter the position of solar panels. Periodic adjustments are made automatically to keep panels oriented towards the sun as it moves across the sky. Modern trackers can detect the sun's position within a few degrees and reposition panels very precisely. Advanced systems also employ solar positioning algorithms and weather data for optimal sun-tracking.
Benefits of Increased Energy Production:
The ability of dual axis trackers to continuously align panels with the sun throughout the day results in significant increases in solar energy harvest compared to fixed or single axis systems. Studies show that dual axis tracking can boost energy production by 25-30% annually on average.
However, gains may be even higher, exceeding 40% in sunny locations with more variable weather patterns. This improved generation has multiple advantages - higher financial returns due to more kilowatts generated, lower levelized cost of energy and increased viability of solar power especially in areas with limited solar resources.
