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.
Hybrid power generation by and solar –windUday Wankar
With the development of industry and
agriculture, a great amount of energy such as coal, oil
and gas has been consumed in the world. Extensive
use of these fossil energies deteriorates a series of
problems like energy crisis, environmental pollution
and so on. Everybody knows that the fossil energy
reserves are finite, some day it will be exhausted.
It is possible that the world will face a
global energy crisis due to a decline in the
availability of cheap oil and recommendations to a
decreasing dependency on fossil fuel. This has led to
increasing interest in alternate power/fuel research
such as fuel cell technology, hydrogen fuel, biodiesel,
Karrick process, solar energy, geothermal energy,
tidal energy and wind. Today, solar energy and wind
energy have significantly alternated fossil fuel with
big ecological problems.
With the development of the science and
technology, power generation using solar energy and
wind power is gradually known by more and more
people. And it is widespread used in many developed
countries. The merits of the solar and wind power
generation are very obvious-infinite and nonpolluting.
The raw materials of the solar and wind
power generation derived from nature, and wind
power generation can work twenty-four hours a day,
solar power generation only works by daylight. In
addition, this kind of power generation has no
exhaust emission and there is no influence to the
nature. But it also has some shortcomings. Because
of the imperfect of the technology, equipment of the
solar and wind power generation is very expensive.
By far, it cannot be widely used.
In addition, solar and wind power
generation system affected by the changing of the
weather very much, so it has obvious defects in
reliability compared with fossil fuel, and it is difficult
to make it fit for practical use the lack of economical
efficiency .Because of these problems it needs to
increase the reliability of energy supply by
developing a system which interacts Solar and wind
energy. This kind of system is usually called windsolar
hybrid power generation system significantly

Solar irrigation system is the green way of energy production,so it is a good option for farmers for irrigation. After the initial cost it will become free of charge to farmers and farmers can install it anywhere.
A flywheel, in essence is a mechanical battery - simply a mass rotating about an axis.Flywheels store energy mechanically in the form of kinetic energy.They take an electrical input to accelerate the rotor up to speed by using the built-in motor, and return the electrical energy by using this same motor as a generator.Flywheels are one of the most promising technologies for replacing conventional lead acid batteries as energy storage systems.
A solar inverter, or PV inverter, converts the direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network.
Energy storage system can actually store energy and use the stored energy whenever the need arises.
As the need for clean energy arises, the need to replace current existing power plants have become a global issue.
NEED OF ENERGY STORAGE

Energy storage systems are the set of methods and technologies used to store various forms of energy.
There are many different forms of energy storage
Batteries: a range of electrochemical storage solutions, including advanced chemistry batteries, flow batteries, and capacitors
Mechanical Storage: other innovative technologies to harness kinetic or gravitational energy to store electricity
Compressed Air: utilize compressed air to create energy reserves. Electricity can be converted into hydrogen by electrolysis. The hydrogen can be then stored and eventually re-electrified.
Pumped hydro-power: creates energy reserves by using gravity and the manipulation of water elevation
Thermal: capturing heat or cold to create energy
The choice of energy storage technology is typically dictated by application, economics, integration within the system, and the availability of resources.

purification of water using solar stillMohamed Ahmed
Distillation is one of many processes that can be used for water purification. This requires an energy input as heat, electricity and solar radiation can be the source of energy. When Solar energy is used for this purpose, it is known as Solar water Distillation. Solar Distillation is an attractive process to produce portable water using free of cost solar energy. This energy is used directly for evaporating water inside a device usually termed a “Solar Still”. Solar stills are used in cases where rain, piped, or well water is impractical, such as in remote homes or during power outages. Different versions of a still are used to desalinate seawater, in desert survival kits and for home water Purification. For people concerned about the quality of their municipally-supplied drinking water and unhappy with other methods of additional purification available to them, solar distillation of tap water or brackish groundwater can be a pleasant, energy efficient option. Solar Distillation is an attractive alternative because of its simple technology, non-requirement of highly skilled labour for maintenance work and low energy consumption.
The use of solar thermal energy in seawater desalination applications has so far been restricted to small-scale systems in rural areas. The reason for this has mainly been explained by the relatively low productivity rate compared to the high capital cost. However, the coming shortage in fossil fuel supply and the growing need for fresh water in order to support increasing water and irrigation needs, have motivated further development of water desalination and purification by renewable energies.

These panels are designed with solar cells composed of semiconductor materials.
The main function of Solar panels is to convert solar energy into DC electrical energy generally of 12V, which is further used for the rest of the circuit. The number of cells required and their size depends on the rating of the load.
The collection of solar cells can produce maximum electricity. But, the solar panel must place exactly at right angles to the sun rays.
Renewable energy sources i.e.,energy generated from solar, wind, biomass, hydropower , geothermal and ocean resources are considered as a technological option for generating clean energy. But the energy generated from solar and wind is much less than the production by fossil fuels, however, electricity generation by utilizing PV
cells and wind turbine increased rapidly in recent years.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

5. Introduction
The aim of our project is to purify water by
using solar energy in rural areas of Bangladesh.
And to purify the water we have used two
methods, they are UV and RO process. We are
using solar energy because in rural areas the
amount of electricity is not sufficient. Sun ray is
available in our country and by using this sun
ray, we will produce electricity.
5
6. Necessity of water purification
Pure drinking water is essential for human life.
According to WHO, 97% population of
Bangladesh have the access of water.
Water born diseases, such as typhoid, cholera,
diarrhea.
2.5 to 15 million children and old people are
affected by diarrhea.

9. Process of water purification
We used two types of process in our project.
Reverse Osmosis (RO).
Ultra Violet (UV).

10. Reverse Osmosis(RO)
What is Reverse Osmosis ?
Reverse Osmosis is a
technology that is used
to remove a large
majority of
contaminants from
water by pushing the
water under pressure
through a semi-
permeable membrane.
10
11. What types of elements are
removed by RO
More than 99% of dissolved salts(ions).
Dust Particles .
Colloids .
Organics.
Bacteria.
Pyrogens.
And many more.
11
12. 12
Ultra Violet (UV)
Ultraviolet, light is an invisible form of
electromagnetic radiation that has a shorter
wavelength than the light humans can see. It
carries more energy than visible light and can
sometimes break bonds between atoms and
molecules, altering the chemistry of materials
exposed to it. UV light can also cause some
substances to emit visible light, a phenomenon
known as fluorescence.

15. Why do we use solar panels?
Reduce the use of
fossile fuel.

process
Easy to carry.
Reduce environment
pollution.
15
16. Charge controller
A charge controller,
charge regulator or
battery regulator
limits the rate at
which electric current
is added to or drawn
from electric batteries.
16
17. Why do we use charge controller
Since the brighter the sunlight, the more voltage
the solar cells produce, the excessive voltage
could damage the batteries.
There are two types of charge controllers.
1. Pulse width modulation(PWM)
2.Maximum power point tracking(MPPT)
17
18. What is Battery?
A battery can change
chemical energy to
electricity by putting
certain chemicals in
contact with each
other in a specific
way.
18
20. What is Inverter?
A power inverter is a
device that converts
DC power (also
known as direct
current), to standard
AC power (alternating
current).
20
21. Type of inverter
Basically there are three types of inverters
1) Square wave Inverters
2) Quasi Square wave or Modified Square
wave Inverters
3) True/Pure Sine wave Inverters
21
22. Equipments of the inverter
Since we will purify water using solar energy so
we have to produce electricity from sun ray through
solar panel. But to collect the electricity we need a
inverter .So we have made a 10W square wave
inverter .
To make inverter we had to collect some
equipments likes IC ,Transistor ,Resister ,
Capacitor, wire PCB Board ,UV lamp, Transformer
etc.
