Established a model of automatic tracking system to keep vertical contact between solar panels and sunlight.
Ppt on solar panel tracking system mechanism.
For example optical power transmission and thermophotovoltaics.
Improved the utilization rate of solar energy and efficiency of photovoltaic.
The rotation axis can be horizontal vertical or oblique.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
Solar trackers are devices used to orient photovoltaic panels reflectors lenses or other optical devices toward the sun.
Although it primarily applies to solar power the principle applies generally to sources with variable power.
Because solar tracking implies moving parts and control systems that tend to be expensive single axis tracking systems seem to be the best solution for small pv power plants.
These provide the signal to motor driver ic2 to move the solar panel in the sun s direction.
Maximum power point tracking mppt or sometimes just power point tracking ppt is a technique used commonly with wind turbines and photovoltaic solar systems to maximize power extraction under all conditions.
To present the tracker a hybrid dual axis solar tracking system is designed built and tested based on both the solar map and light sensor based continuous tracking mechanism.
1 shows the circuit of the solar tracking system.
These light sensors also compare the darkness and cloudy and sunny conditions assisting daily tracking.
Principle of sun tracking solar panel.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
This article describes about circuit that rotates solar panel.
Since the sun s position in the sky changes with the seasons and the time of day trackers are used to align the collection system to maximize energy production.
The search mechanism p ilot locates t he position of the sun and the.
Pv solar systems exist in many different configurations with regard to their relationship to inverter systems ext.
So solar panel should continuously rotate in the direction of sun.
Conclusion the invention of solar tracking system helps us improve the performance of pv solar system in a simple way used relative method of sunlight strength.
