Solar power (photovoltaic) systems

INTRODUCTION

1.1 BACKGROUND OF THE PROJECT
The consumption of the energy is directly proportional to the progress of the mankind. With ever growing population, improvement in the living standard of the humanity, industrialization of the developing countries, the demand for energy increases day by day.
The primary source of energy is fossil fuel, though results environmental degradation caused by their widespread use, particularly global warming, urban air pollution and acid rain, this has increased the demand and request for green energy produced by renewable sources such as solar power
Solar power is an alternative technology that will hopefully lead us away from our petroleum dependent energy sources. The major problem with solar panel technology is that the efficiencies for solar power systems are still poor.
Solar power (photovoltaic) systems are a sustainable way to convert the energy of the sun into electricity. The expected lifetime of a system is 25-30 years. This show how efficient is this system even it is quite expensive to install this system at the beginning. Amount of power produced by a photovoltaic panel depends upon the amount of sunlight it is exposed to. In other word, more light means more power.


1.2 OBJECTIVE
Below are the main objectives of “Optimized Electrical Power from the solar using microcontroller” project.
To design a project that can detect and compare the intensity of light
To design a project that able to move a Dc motor based on the intensity of light and show the direction
To maximize the generation of electrical energy. Each day, the sun rises in the east, moves across the sky, and sets in the west.
So if the solar panel is rotated along the sun path it would be receiving the maximum amount of sunlight possible and converting it into the more useful energy form electricity
Hence it will Increases the efficiency of solar power hence facilitate the utilization of green power.


1.3 PROJECT SCOPE
This project is focused to design and construct the prototype of solar tracking system,
Therefore, this prototype will cover the scope as followed.
Using microcontroller (AT89C51).
Using Dc motor (10rpm, 12v, rotation CW/CCW) which is chepear.
Using Light Dependant Resistor (LDR) as a sensor.
Using 2 sensors (LDRs) to detect and compare the solar intensity of light.
