IntroductionIntroduction Global warming has increases the demand and request for green
energy producing by renewable sources as an example solar power There are two main ways to make the solar cells more efficient,
either by improving the actual cell or by installing the solar panels on a tracking base that follows the sun
The tracking system is able to track the sun from east in the morning to west in the evening
The ability in tracking the solar energy increases the efficiency by 20-62% and also the output of solar panel
Solar panel is the most vital part of solar power system in producing electricity and able to capture the sun’s heat directly before converting into electricity power
Problem StatementProblem Statement
Fixed type solar panels are not able to capture the sun light when the sun planet moves to other way round
There are two main ways to make the solar cells more efficient, either by improving the actual cell or by installing the solar panels on a tracking base that follows the sun
The ability in tracking the solar energy increases the efficiency by 20-62% and also the output of solar panel
The tracking system is the best way in improving solar cells which reacts to Earth rotation against to sun planet
ObjectiveObjective To design and construct a single axis solar tracking system which
able to reacts to Earth rotation against to sun planet To build a microcontroller solar array that actively tracks the sun to
maximum solar panel output To build a sensors to locate the sun's position at any instance and
aligning the array using the microprocessor so that all incident rays are normal to the array surface
Project ScopeProject Scope To design a control system that track the movement of sun to
maximize the output of the solar panel by using microcontroller To determine type of sensor which suitable to attract the sun
position to solar panel

Sun Tracking Sensors (STS)Sun Tracking Sensors (STS)
Step-1, shows when sun is in front of solar panel, both sensors i.e. STS-1 & STS-2 getting same amount of light
Step-2, after some time earth rotates the solar panel gets repositioned with respect to sun and STS-1 abstains less amount of light and Photodiode STS-1 sends signal to the microcontroller to rotates motor, resulting the rotation of solar panel towards the sun
Finally step-3 shows the reorientation of solar panel and continues until the end of day
Example Of Solar Tracking SystemExample Of Solar Tracking System
Fixed Solar Panel
Solar Tracking System
ComparisonsComparisonsFixed Solar Panel Fixed ground system, means panels only can be fix in certain places
to catch sun light Not able capture sun light when sun planet moves other way round Decrease of their efficiency
Solar Tracking System Able to reacts to Earth rotation against sun planet to catch sun light Able to track sun light form east in the morning to west in the
evening Solar energy increases the efficiency and also the output of solar
panel
Statement Of HypothesesStatement Of Hypotheses There are two main ways to make the solar cells more efficient,

Significance Of StudiesSignificance Of Studies Solar panel is the most vital part of solar power system in
producing electricity Solar panels able to capture the sun’s heat directly before
converting into electricity power Use of solar power for residential use is developing and catching
the world market In growing towards greener ways to power the world and minimize
greenhouse gas emissions, solar power (photovoltaic) system is a sustainable way to convert the energy of the sun into electricity
