The main aim of this project is to develop LED based street lights with auto intensity control system by using Arduino board and solar power from photovoltaic cells.
SOLAR STREET LIGHTING SYSTEM SHOULD BE USED TO DECREASE THE ENERGY DEMAND IN HIGHWAYS ALSO RENEWABLE ENERGY SOURCES CAN BE UTILIZED MORE AND MORE TO REDUCE THE MASSIVE USES OF FOSSIL FUELS WHICH ARE EXTINGUISHABLE.
This system builds upon topics learned in this course. The aim of the project is to keep the
solar photovoltaic panel perpendicular to the sun throughout the year in order to make it more
efficient. The dual axis solar photovoltaic panel takes astronomical data as reference and the
tracking system has the capability to always point the solar array toward the sun and can be
installed in various regions with minor modifications. The vertical and horizontal motion of
the panel is obtained by taking altitude angle and azimuth angle as reference. The Arduino has
been used to control the position of DC servo motors. The mathematical simulation control
of dual axis solar tracking system ensures the point to point motion of the DC motors while
tracking the sun.
Project details - I have made a project Dual Axis Solar Tracker using Arduino to align the solar panel towards the higher density of Sun light. I have used a ATMEGA168 controller IC for programming, and two servo motor for movement of solar panel.

The solar energy is converted to electrical energy by photo-voltaic cells. This energy is stored in batteries during day time for utilizing the same during night time. A charge controller, or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

radiates an enormous amount of energy every second.
Solar cell works on the principle of photovoltaic effect. Sunlight is
composed of photons, or "packets" of energy.
These photons contain various amounts of energy corresponding to the different wavelengths of light.
When a photon is absorbed, the energy of the photon is transferred to an electron in an atom of the cell.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Introduction
Arduino Based Solar Street
Light
The project is designed for LED based street lights with auto
intensity control by an Arduino board using solar power from
photovoltaic cells. As awareness for solar energy is increasing,
more and more individuals and institutions are opting for solar
energy. Photovoltaic panels are used for charging batteries by
converting the sunlight into electricity. A charge controller
circuit is used to control the charging.
7. http://www.edgefxkits.com/
Solar Panel:
Arduino Based Solar Street
Light
A solar panel is a collection of solar cells. The solar panel converts the
solar energy into electrical energy.
Output of the solar panel is its power which is measured in terms of Watts
or Kilo watts. Solar power uses multiple reflectors to collect more sun’s
thermal energy.
Thermal energy collected through the day to perform different operations.
Performance of the solar panel depends on a number of factors like
climate, conditions of the sky, orientation of the panel, intensity and
duration of sunlight and its wiring connections.

Arduino Based Solar Street
Light
Charge controller circuit:
If the battery voltage is below 12V, then the current from LM317 IC
flows to the battery.
The current flow to the battery stops when the battery voltage rises
to 13.5V. Hence charge controller circuit will prevent the battery to
flow high current through it.

Rechargeable Battery:
Arduino Based Solar Street
Light
A rechargeable battery, storage, secondary battery or accumulator is a
type of electrical battery which can be charged, discharged into a load,
and recharged many times, while a non-rechargeable or primary battery
is supplied fully charged, and discarded once discharged.
Several different combinations of electrode materials and electrolytes
are used, including lead–acid, nickel cadmium (NiCd), nickel metal
hydride (Ni-MH), lithium ion (Li-ion), and lithium ion polymer (Li-ion
polymer).

Voltage Divider circuit:
Arduino Based Solar Street
Light
A voltage divider is a simple circuit which turns a large voltage into a
smaller one.
Using just two series resistors and an input voltage, we can create an
output voltage that is a fraction of the input.
Voltage dividers are one of the most fundamental circuits in electronics
equation of circuit.

Arduino UNO:
Arduino Based Solar Street
Light
Micro-controller will control the intensity of light at different time
slots.
Micro controller circuit will generate PWM waves at a particular time
using RTC (Real Time Clock) these system provide sets of digital and
analog I/O pins that can be interfaced to the street light circuit.
Operating voltage of Arduino UNO is 5v so that we will convert 12v
from Battery to 5v.

Arduino Based Solar Street
Light
Solar Panel
Expose the cell to light, and the energy from each photon (light
particle) hitting the silicon, will liberate an electron and a
corresponding hole.
If this happens within range of the electric field’s influence, the
electrons will be sent to the N side and the holes to the P one,
resulting in yet further disruption of electrical neutrality

Light Dependent Resistor
(LDR) :
Arduino Based Solar Street
Light
Light dependent resistor is used to detect change in light intensity or
as a light sensor. LDR is basically a variable resistor.
LDR resistance changes with the change in intensity of light. If
intensity of light falling on LDR is high, LDR will have low resistance.
When intensity of light decreases, LDR offer high resistance. Hence
there is a inverse relationship between intensity of light and resistance
of LDR.
15. http://www.edgefxkits.com/
Arduino Based Solar Street
Light
The LDR is a resistor, and its resistance varies according to the amount of
light falling on its surface.

Relay :
Arduino Based Solar Street
Light
In this project, relay is used to provide isolation between low voltage
circuitry and high voltage circuitry.
Arduino is also used to provide control signal to relay whenever intensity
of light falls below a certain level.
Control signal is generated from pin 13 of Arduino which is used as a
output pin. Transistor is used as a switch here.
