Many of the people have a phobia of darkness, so to assist them in such situation, we have explained a simple circuit. It will automatically turn on street light in the way of LEDs or bulb coupled with relay. Working this circuit is very much easy and also the power consumed by the circuit is very low because of the very few components used in the circuit.
This ppt describes how to detect vehicle movement on highways to switch ON only a block of street lights ahead of it (vehicle), and to switch OFF the trailing lights to save energy.

1. SMART STREET LIGHT SYSTEM Design Report Kuriakose Mathew Libin Thomas Midhun Shaji
2. PROBLEM STATEMENT Automatic switching of street lights considering the intensity of sunlight, brightness control of lights on detecting movement and error reporting to electric sub sections.
3. PROJECT SCOPE/OBJECTIVE Smart street light system tries to find solution for the faster depletion of energy resources due to the inefficient usage and wastage of these resources. Increasing electricity bill is something that can be witnessed by these practices. This project help to decrease the wastage of electricity by controlling the working of street light system that attributes to a good amount of electricity bills in our nation This project does not include methods to incorporate usage of renewable resources like solar energy.
4. DESIGN AND IMPLEMENTATION CONSTRAINTS Constraints are mainly in the module that regulate the brightness of the light by considering the traffic on the street at a specific time. Infrared proximity sensors are costly and at the same time maximum distance to which the sensor can sense is limited to 1 metre, which may not be sufficient for a 45 metre road.
5. DEVELOPMENT METHOD This project include three modules, the sunlight sensing and control of onoff of the lights, the traffic sensing and brightness control, error reporting system. Microcontroller used is arduino uno r3 atmega 328p ,which has to be programmed for the three tasks. Inputs for the same come from the three sensors.output include instruction to onoff the control sytems.
6. SYSTEM OVERVIEW
7. SYSTEM FEATURES/USE CASES System for controlling onoff of lights Use Case Description Sunlight intensity less than 250 lux Sunlight intensity grater than 250 lux Flow of events If the intensity is less than 250 then switch on the lights Else switch off the light

DESIGN AND FABRICATION OF SOLAR POWERED WATER PUMPING SYSTEM WITH AUTO TRACKI...ARUL S
Solar energy is converted to mechanical energy by absorbing the solar radiation from the sunlight. In this
paper we have introduced a solar photo voltaic cell for collecting the sun rays through the solar array and
transforming this sun rays in to electricity to generate the electricity. The main aim of this project is to supply
electricity through the sun rays and its for the purpose of irrigation in the rural areas where the electricity scare is
expected. In our solar kit we have introduce an Automatic solar tracker which stimulates and increases the
efficiency of the solar panel by keeping the solar panel which moves according to the direction of movement of sun
rays. A solar PV cell is a electrical device that converts the energy of light directly to electricity by the photovoltaic
effect. A photoelectric cell is defined as an device whose electrical characteristics like current, voltage, resistance,
varies when exposed to light. Solar cells are the basement for any photovoltaic modules panels. Solar cells are used
as a photo detector for detecting light near the visible range, or measuring light intensity.Water pumping worldwide is generally dependent on conventional electricity or diesel generated
electricity. Solar water pumping minimizes the dependence on diesel, gas or coal based electricity. The use of diesel
or propane based water pumping systems require not only expensive fuels, but also create noise and air pollution.
The overall upfront cost, operation and maintenance cost, and replacement of a diesel pump are 2–4 times higher
than solar photovoltaic (PV) pump. Solar pumping systems are environment friendly and require low maintenance
with no fuel cost . Keeping in view the shortage of grid electricity in rural and remote areas in most parts of world,
PV pumping is one of the most promising applications of solar energy. The technology is similar to any other
conventional water pumping system except that the power source is solar energy. PV water pumping is gaining
importance in recent years due to non-availability of electricity and increase in diesel prices. The flow rate of
pumped water is dependent on incident solar radiation and size of PV array. A properly designed PV system results
in significant long-term cost savings as compared to conventional pumping systems. In addition, tanks can be used
for water storage in place of requirement of batteries for electricity storage Agricultural production in developing
countries is largely dependent on rains and is adversely affected by the non availability of water in summers.
However, maximum solar radiation is available in summers as such more water can be pumped to meet increased
water requirements. Urban water supply systems are also dependent on electricity to pump water in towns. There is
a wide scope to utilize PV pumping systems for water supplies in rural, urban, community, industry and educational
institutions.Solar panel, Microcontroller board (pic16f877a), Soil moisture. TNX

Introduction:
Solar energy is nothing but the radiant energy emitted by sun. We may
convert this solar energy into electricity either directly using photo
voltaic (PV), or indirectly using concentrated solar power (CSP) with
the help of lenses or mirrors and tracking systems to focus a large area
of sunlight.
This solar energy is mainly useful in solar street lights, auto solar
irrigation system, traffic junction signal lighting etc.

Photovoltaic panels are used for charging batteries by converting the
sunlight into electricity. A charge controller circuit is used to control the
charging.
Intensity of street lights is required to be kept high during the peak
hours. The street lights switch ON at the dusk and then switch OFF at
the dawn automatically. The process repeats every day.

Solar Panel:
Solar panel is one of the most important parts of solar street lights, as solar
panel will convert solar energy into electricity.
There Are 2 Types Of Solar Panel:
• Mono-crystalline
• Poly-crystalline.
Conversion rate of mono-crystalline solar panel is much higher than poly-
crystalline.

Lighting Fixture:
LED is usually used as lighting source of modern solar street light, as
the LED will provide much higher lumens with lower energy
consumption.
The energy consumption of led fixture is at least 50% lower than hps
fixture which is widely used as lighting source in traditional street
lights.
Led’s lack of warm up time also allows for use of motion detectors for
additional efficiency gains.

Rechargeable Battery:
Battery will store the electricity from solar panel during the day and provide
energy to the fixture during night.
The life cycle of the battery is very important to the lifetime of the light and the
capacity of the battery will affect the backup days of the lights.
There are usually 2 types of batteries: gel cell deep cycle battery and lead acid
battery.

Controller:
Controller is also very important for solar street light.
A controller will usually decide to switch on /off charging and lighting.
Some modern controllers are programmable so that user can decide the
appropriate chance of charging, lighting and dimming.

Pole:
Strong poles are necessary to all street lights, especially to solar street
lights as there are components mounted on the top of the pole: fixtures,
panels and sometime batteries. And wind resistance should also be
taken into consideration when choosing the pole.
Solar Powered Led Street Light with

Circuit Explanation:
The system consists of two circuits – the charge control circuit and the
load intensity control circuit.
The charge control circuit consists of 4 parts - overcharge indication,
over load detection with protection and low battery voltage detection
with indication. For each part one comparator of a quad a comparator
IC LM324 is used.
The load intensity control part consists of the microcontroller which
controls the power supply to the load through the transistor and mosfet
switch so as to vary the intensity of the leds. Here an array of leds is
connected as the load.

Advantages:
Solar street lights are independent of the utility grid. Hence, the
operation costs are minimized.
Solar street lights require much less maintenance compared to
conventional street lights.
Since external wires are eliminated, risk of accidents is minimized.
This is a non-polluting source of electricity.
Separate parts of solar system can be easily carried to the remote areas.

Disadvantages:
Initial investment is higher compared to conventional street lights.
Risk of theft is higher as equipment costs are comparatively higher.
Snow or dust, combined with moisture can accumulate on horizontal
pv-panels and reduce or even stop energy production.
Rechargeable batteries will need to be replaced several times over the
lifetime of the fixtures adding to the total lifetime cost of the light.
The batteries have to be replaced from time to time.
Solar Powered Led Street Light with
Auto Intensity Control
16. http://www.edgefxkits.com/
Features:
Most solar panels turn on and turn off automatically by sensing outdoor
light using a light source. Solar streetlights are designed to work
throughout the night. Many can stay lit for more than one night if the
sun is not available for a couple of days.
Older models included lamps that were not fluorescent or led. Solar
lights installed in windy regions are generally equipped with flat panels
to better cope with the winds.
Latest designs use wireless technology and fuzzy control theory for
battery management. The street lights using this technology can operate
as a network with each light having the capability of performing on or
off the network.

Conclusion:
The solar energy is one of the important and major renewable sources of
energy and has also proven it useful in functioning of applications like
street lights.
The charge control is necessary in order to achieve safety and increase
the capacity of the battery. In cities, currently thousands of street lights
are operated and the yearly electricity maintenance cost is very high.
The initial cost and maintenance can be the draw backs of this project.
With the advances in technology and good resource planning the cost of
the project can be cut down and also with the use of good equipment the
maintenance can also be reduced in terms of periodic checks.
