Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.
Ppt on solar panel tracking system mechanism.
For example optical power transmission and thermophotovoltaics.
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.
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.
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.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
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.
The aim of automatic solar tracker is to design the system which will automatically track the sun s position and accordingly change the direction of the solar panel to get the maximum output from the solar cell.
This article describes about circuit that rotates solar panel.
Download automatic solar tracker ppt presentation slides and seminar report in pdf for free for cse students.
So solar panel should continuously rotate in the direction of sun.
This solar tracking system is cont rolled by a micro chip pic 18f452 micro controller.
These light sensors also compare the darkness and cloudy and sunny conditions assisting daily tracking.
A single axis solar tracking system uses a tilted pv panel mount and one electric motor to move the panel on an approximate trajectory relative to the sun s position.
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.
Although it primarily applies to solar power the principle applies generally to sources with variable power.
Pv solar systems exist in many different configurations with regard to their relationship to inverter systems ext.
Improved the utilization rate of solar energy and efficiency of photovoltaic.
Principle of sun tracking solar panel.
1 shows the circuit of the solar tracking system.
Established a model of automatic tracking system to keep vertical contact between solar panels and sunlight.
The search mechanism p ilot locates t he position of the sun and the.
The rotation axis can be horizontal vertical or oblique.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
