Introduction:

Extracting usable electricity from the sun was made possible by the

discovery of the photoelectric effect.

Subsequent development of the solar cell, which is a semi-conductive

material converts visible light into a direct current.

Solar arrays, a series of solar cells electrically connected, generates a dc

voltage which can be used on a load.

Solar arrays are being used increasingly as efficiencies reach higher

levels, and are especially popular in remote areas where placement of

electricity lines are not economically viable.











What Is A Solar Tracker?

A solar tracker is a generic term used to describe devices that orient or

align various payloads toward the sun.

Example for payloads are photovoltaic panels, reflectors, collectors,

lenses or other optical devices.

The system focuses on the optimization of the electric energy produced

by photovoltaic cells through the development of a sun-tracking system












Solar Panel:










Need For A Sun Tracking System:

We Get Maximum Energy From The Sun When The Angle Of The Sun

Is In Degrees. The Sun’s Position Is 0 +/- 5 Degrees Of The Equator.

Global Warming Has Increased The Demand And Request For Green

Energy Produced By Renewable Sources Such As Solar Power.

Consequently, Solar Tracking Is Increasingly Being Applied As A

Sustainable Power Generating Solution.

Concentrators, Especially In Solar Cell Applications, Require A High

Degree Of Accuracy To Ensure That The Concentrated Sunlight Is

Directed Precisely To The Powered Device.











Basic Components:

The solar panel

Stepper motor

Actuator

Microcontroller

A display unit (optional)

Interfacing cables











How Sun Tracking Solar Panel Works?

Initially powers the circuit.

Place the set up in dark.

When the two LDRs are in dark, there is no movement in the panel.

Now place a torch in front of the left LDR. Panels slowly move towards

its left.

Now move light from left to right. You can observe the panel moving

slowly with the torch towards right.

In the middle, when intensity on both LDRs is equal, panel will not move.











Applications:

Can Be Used For Small And Medium Scale Power Generations.

For Power Generation At Remote Places Where Power Lines Are Not

Accessible.

For Domestic Backup Power Systems, This Can Be Used In Industries

As More Energy Can Be Saved By Rotating The Panel.











Advantages:

Solar tracking systems continually orient photovoltaic panels towards

the sun and can help maximize your investment in your PV system.

One time investment, which provides higher efficiency and flexibility on

dependency over other sources.

Sun Tracking Solar Panel systems can help reducing emissions and can

contribute against global warming.

Bulk implementations of tracking systems help reduced consumption of

power by other sources.

The solar energy can be reused as it is non-renewable resource.

Disadvantages:

Initial Investment Is High On Solar Panels.

It’s A Bit Of Difficult For Servicing, As The Tracking Systems Are Not

Quite Popular Regionally.

Moving Parts And Gears Which Will Require Regular Maintenance.

May Require Repair Or Replacement Of Broken Parts Over A Long

Run.











Conclusion:

On one hand we can see the world’s energy resources depletion to be a

major problem.

On the other hand global warming, which is a major concern.

Switching to solar power, which is clean and green and enhancing its

efficiency by using sun trackers is a great option in the near future.
