Why Solar energy?
Because, it is ultra clean, natural and a sustainable source of
energy that you can utilize in the use of making solar
electricity, solar heating appliances, solar cooling appliances
and also solar lighting appliances.
Another key aspect of
using solar energy is that it has massive financial benefits. They
can generally be seen in the reduction of your utility bills. As
you would be consuming solar power for the electricity that you
use, the heating, the cooling and the lighting of your
environment. Statistically, in the United States, Americans are
known to be consuming 25% of the world’s oil production on a daily
basis. On the whole, the planet is being drained of its oil
resources and the energy prices are only bound to go up. To only
mend your own personal cost of energy needs is probably one of the
smartest things to do and not to forget a very valuable future
investment, when measured up to the unavoidable rise in the cost
of energy in recent times as well as the not so far future. Solar
energy systems are very much affordable, and with the help from
the local, state and the federal programs that are now available
to help in the installation costs, they seem to make much more
sense than using other sources of generating energy apart from the
Conversely, if you take benefit of the law
that was passed in 2005, which is mainly referred to as the law of
the net metering, you can actually end up saving on the price of
the batteries and use extra power back into the utility network,
which if you ever have the need to use it, can do so easily. This
in short means that the utility corporation actually turns into
being your own personal storage facility, with absolutely no extra
fund cost to your wallet.
On the global front, creating the
use of solar energy seems to be one of the best options available.
The change in the climate world over is a serious threat to our
planet which is causing much of the problems. The emission levels
of carbon dioxide that we generate by the constant use of fossil
fuel are literally killing our planet. The usage of solar energy
will only provide us with a clean environment, a life where we
will not have to constantly worry about the ever so reducing
resources to provide us with the basic comforts of our life. With
net metering, the ever so reasonably priced solar technology and
the ultimate willingness to change this situation around, you can
augment the energy competence of your home, and in due course
accomplish net zero fossil fuel expenditure and utilization. You
will also save the planet from dying out by using solar energy!
is hardly anyone who has not heard about solar energy, and if one
knows what solar energy is, it is certain to be known that sun has
something to do with it. Well sun has almost everything to do
with; it is only sun who manages to provide 1000 watts per square
meter. That is enormous amount of energy to take, if we have
enough solar cells array to place on open land to capture energy.
There is one most common example for solar product is
calculator which we use in our homes and office. These calculators
do not have batteries but operates on solar cells and usually it
remains on and do not have off buttons, for them to keep on
working only light is required. There are little advance examples
for solar power applications available in fewer parts of the
world, solar application like solar signals on highways, emergency
road signs, emergency call boxes, parking lights and garden
Have you ever wondered, "Why is solar energy important?" You
are not alone. With all of the talk in the media about
alternative energy, it is a common question.
delve into the discussion of why solar energy is so needed in
the world today, we’ll first look into what solar energy really
is. By definition, solar energy is that beaming light and heat
that is generated from the sun. Solar energy has been used by
human beings since time immemorial. Solar power is used in a
widespread of the ever so progressing technologies of the
The radiation that comes from solar energy along
with the resultant solar energized resources such as wave
power, wind, biomass and hydroelectricity all give an
explanation for most of the accessible renewable energy that is
present on earth. However, only an infinitesimal portion of the
existing solar energy is used.
So the question of why
solar energy is important, that persists in the minds of many,
is because solar energy can prove to have an immense amount of
constructive and helpful impact on you and on the environment
as a whole. Contrasting to the fossil fuels that we consume and
use on a daily basis, solar energy does not fabricate the
excessively injurious pollutants that are liable for the
greenhouse effect which is known to lead to global warming.
Solar power use reduces the quantity of contamination and toxic
waste, not to forget pollution that the engendering plants have
to produce. Global warming is an issue of great interest. In
the recent times, with more awareness about the harmful effects
of global warming, the issue is taken with great interest.
There is in point of fact a massive belief that the use of
fossil fuel is a contributing factor to the cause of global
warming, which will ultimately result in the demise of the
planet altogether. Probably the best part about why solar
energy is that it is a renewable source of energy, which
basically means that it will stay there forever, it will be
consumed for all practical human usages. Oil, coal etc, is all
bound to finish one day and eradicate from the face of the
planet. So why not put them in the storage and use something
more useful, is a basic question that many people have today.
To understand how solar power panels work and provide
electricity I have broken down its working and processes in to
steps for better understanding. These steps are mentioned with
the in the order as it happens in given solar plant. Steps like
Sun light, Earth surface, Photovoltaic Cells, Weather Station,
DC switch, Inverter, Transformer, AC switch, Electric meter.
1. SUN LIGHT: Sun is the only source for light for
earth, sun produces enormous amount of energy due to fusion
reactions with in its core. Portions of energy are travelled to
the surface of the earth; these portions of energy are called
photons. Sun light passes through different layers before
entering into atmosphere of earth, these layers have specific
filtration process which filter harmful energy and light and
prevent it to reach on earth. The energy which gets in the
atmosphere is reflected and absorbed by earth, crops water,
oceans etc and some of the energy is reflected back into space.
Rest of the energy is available to take to produce energy from.
2. Earth Surface: Earth receives enormous amount of
radiant energy from the sun, even after reflection of most of
the energy during traveling from sun to earth. This energy
available is still on huge scale to be converted into
electricity using solar panels. Sun light is the most important
part to complete life cycle of human beings and other living
organisms including animals and plants. Combination of sun
light, sea and atmosphere creates wind pressure which keeps
weather systems of earth intact, these winds can also be
utilized for producing electricity with help of wind machines.
3. Photovoltaic Cells: The most important component of
solar panel which produces electricity is photovoltaic cells.
The basic function of photovoltaic cells is to convert sun
radiant energy into electricity. The word photovoltaic it self
means light energy, photo means light and voltaic means energy.
Each photovoltaic cell is packed into modules which are called
arrays. These cells produce DC direct current when sun is
shining directly over them, produced electricity is then send
to building electric system or grid station for next step.
Inverter: Inverter is device which converts direct current (DC)
into usable Alternative current (AC). Photovoltaic cells
produce direct current which inverter converts into alternative
current so that it can be consumed by building. Most of
electric devices like computers, house lights, air conditioners
etc require alternative current (AC) to operate. These are four
steps which are must to be taken place for any solar panel to
work. However there may be some additional steps which can be
installed by different companies to enhance and improve the
maintenance and overall performance or entire solar panels.
These steps may include, electric meter, weather station
device, DC switch disconnection module, Transformer, AC switch
disconnection module, data acquisition module, electricity
distribution panel module.
Electric meter: These
electric meters are used for the same purpose as our normal
electric meters are used for. They keep the record of energy
being consumed which is produced by solar panels. Normally
electric energy is measured in watts or kilowatts. Most of
solar panels come with electric meters especially when panels
are designed to produce energy on large scale.
acquisition module: Data acquisition module is important module
which receives inputs from weather station module and electric
meter. It is normally designed in such a way that it gathers
important information to calculate weather conditions and
output of solar panels.
Weather Station module: Weather
station is another useful add-on for solar panels. As name
suggests it keeps the record of weather conditions. Weathers
conditions are very crucial as far as the performance or solar
panels are concern, therefore keeping weather conditions as
record is important. These modules are normally located near
photovoltaic cells or arrays. Weather station normally have
anemometer to keep the record for wind speed, pyranometer keeps
record for solar energy falling on solar panel arrays and of
course thermometer to measure temperature. All these inputs are
then send to data acquisition module for further processing.
Transformer is an important component for any electric system;
it makes sure that electricity coming from inverter is
compatible with electric voltage of house, building office etc.
DC switch disconnection module: This module helps
professional solar panel electricians to disconnection solar
panel from the rest of its system. When DC switch is off,
electricians can do maintenance task on the rest of solar panel
AC switch disconnect module: This module
allows electricians to disconnect electric supply of house or
building from photovoltaic system. With AC switch turned off
maintenance of solar photovoltaic system can be performed.
distribution panel module: This module is designed to receive
energy from solar panels which is then combined with other
electricity supply company. From here this energy is passed on
electric wiring all over the building, house office etc to run
Using latest technologies like
nontechnology and bio developed solar panels are already on
scene, these panels are not yet commercially lunched, however
they are on scene and will be available for public and
commercial use within couple years.. Portable, flexible and
folding PV (photovoltaic) array modules are present today
providing ease of use.
Solar electricity is definitely the choice of future by energy
analysts throughout the world, especially if we keep any eye
over other power generation sources fuels, gas etc and their
rising prices all the time. Countries have struggled in recent
past due to fuel resource for managing their country needs.
That is going go on and increase in future if alternative
energy/ renewable energy sources are not exploited to their
maximum available potentials. Read below the most obvious
advantages of solar energy
There are countless
advantages associated with Solar Energy. Uses for solar energy
are not just for humans to take advantages from but it is
amazingly useful for environment as well. Lets’ go through
several advantages of solar energy.
• The most
unique and best feature of solar energy is its abundance in
quantity available to our mother earth, if we use it to maximum
levels it is not going to go anywhere until next five billion
• The most unique and best feature of solar
energy is its abundance in quantity available to our mother
earth, if we use it to maximum levels it is not going to go
anywhere until next five billion years.
• Solar energy
can is easily be provided in rural areas where conventional
electricity is not present already or it may cost more to setup
electric grid station. It is cost effective to use solar energy
generation methodologies in such rural areas.
power plants can also be connected to existing source of power
generation to form hybrid system to boost energy requirements
during sunny, hot and dry day.
• Solar power plants are
normally very flexible. Solar cell modules or arrays comes in
different shapes and sizes, it can be fixed on land or can be
mounted on roof tops for maximum sun light exposure. Solar cell
modules can also be fixed on glass skylights or vertical walls.
• Solar panels now come equipped with such devices which
converts DC output from solar panels into AC for consumption.
This way residential and commercial business owner can reduce
their conventional electricity bills which are increasing day
• Net metering is another impressive advantage
of using solar energy. Net metering is term which refers to
selling energy to conventional grid station in cases of excess
production using solar panels. This way electricity bills are
reduced by sending electricity back to grid station.
Solar power panels are durable and do not require much
maintenance, once in while cleaning of solar cell modules will
be it. Average life time of solar power panels are up to 20 to
25 years, which justify the initial cost of solar panel.
Solar power systems are soundless, efficient and without any
pollution. Solar panels are capable of connecting with other
type electric generators for instance gas turbines, wind, hydro
etc. Batteries can also be charges for constant electricity
• Larger solar power panels can help in meeting
the demands of new power generation sources. These panels are
easy to develop then other power generation plants. Solar power
panels are very easy to expand, all is require adding up solar
cell modules into it and it will start producing more
• Solar power systems are very friendly to
environment and do not pollute it in anyway, they do not have
any by product only electricity is produced. When solar
electricity is used in place of energy generated by fossil
fuels for meeting needs like lightening homes, office
buildings, pumping of water etc, it will reduce amount of
carbon-monoxide, greenhouse gasses and other pollution emitted
into air. The more electricity from solar panels is used the
more it is benefited for environment to reduce impurities from
We all should step ahead for solar electricity, create
opportunities by exporting solar electric systems to developing
countries, reduce the usage of conventional electricity and
protect global environment and reduce global warming phenomenon
Energy is the part and parcel of life. Life is
unimaginable without energy. There will be no life after the
extinction of energy. We make good use of energy. It is
everywhere around us and in us. There is not only one type of
energy. There is heat, electricity, light. Energy is stored in
our bodies. The energy present in the molecules of
carbohydrates, proteins and other substances enable us to
breathe, move, grow, think, speak and live. In working, playing
and doing anything even sleeping need energy.
beings are living on this planet from billions of years. They
have suffered to make their lives easier. The humankind has
invented millions of appliances and machines to make the
lifetime easier and comforting. Some of these machines make use
of electricity to fulfill our needs where others use fuel to
fulfill the task. Heat and electricity are the most common
forms of energy. The moving particles in any substance generate
heat. The warmth depends on the movement of the particles. The
movement of electrons in a conductor like copper electric wire
creates electricity. Besides heat and electricity there are
also a number of other energies that we are making use of.
is easy to convert energy from one form to another. We have to
use energy in different products and have to change the type of
energy in accordance to the equipment that will make use of it.
The transmission of energy is also an issue as the energy is
not produced in the place where it is required. Energy can be
divided in two basic types:
• Renewable energies
The non-renewable forms of energy
are the one who exhaust on exploitation, for example natural
gas, oil, radioactive elements, coal, etc. the renewable energy
is replaceable. The supply is never ending. The energy is
extracted from the natural sources in natural manner without
spoiling the natural flow. The renewable energy comes from the
sun rays, water, wind and many other natural resources. By the
virtue of collectors, designed for the purpose, we can store
energy from these resources and utilize them for our specific
purpose. Such supply of energy will continue to serve us unless
or until water (oceans) is flowing, sun is blazing, wind is
blowing and trees are growing.
Sun is providing us with
extensive amount of energy from the very first day of its dawn.
Sun provides us with heat, light, X-ray and radio waves. There
are collectors and modules to collect the sun energy and to
convert it into different usable forms of energies. Solar
energy is a brilliant source of most popular forms of energies
that is heat and electricity. For remote use of energy, solar
power is getting popularity like agriculture applications such
as pasture management and irrigation, tropical states that are
detached from electricity grid, for heating swimming pools,
telecommunication towers and much more.
The sun light
casting upon water and earth cause the air to move above at
getting warm, that gives wind which has been one of the best
sources of energy from ages. Initially wind was used for
carrying ships, grinding grains, pumping water and much more.
Today wind is one of the cleanest and renewable sources of
energy. Biomass is composed of different forms of energy.
Biomass refers to straw, wood, biological waste products, etc.
in energy industry as they contain abundant energy. The
reserved energy can be released by burning the biomass or by
presenting it to micro organisms that can be utilized it to
Water is used by the mankind for more than
3000 years ago. Hydroelectric dams are created to collect the
potential of water. The snow falling and rain provides water to
the reserves. Moving water is a renewable and everlasting
source of energy.
The renewable sources are useful as
they are cost effective. The non-renewable sources of energy or
fossil fuels are getting expensive as the reserves are getting
exhausted with increasing usage. Besides, fossil fuels are
spoiling the atmosphere as well as the aqua life. On the other
hand, the renewable sources of energy are environment friendly
and do not affect the natural order of the planet. The sources
will never exhaust and will cause no trouble in case the demand
will be increased by the passage of time.
It is time
that we must start to think about things at larger canvas. It
is time that we should realize our duty to the mother earth and
change the way we are behaving from ages. The change is only
possible if we are ready to rely on the latest techniques and
to reject the conventions. Let us come and join hands to save
our planet that is the last hope of life of human beings.
is renewable energy?
Our mother earth relies on fossil
fuels heavily, like oil, coal and natural gas to meet energy
requirements. Fuels which we burn to produce energies are not
reversible and reusable. Experts and analysts have been
predicting about current earth sources, according to them these
fuels are going to decrease to dangerous levels if consumption
ratio remains the same or increase in future.
these fuels are already getting higher and carbon emissions
from such fuels are damaging clean environment of the earth.
Considering all these factors it is urgent to consider and
adopt renewable energy sources.
Types of renewable
In contrary to fossil fuels, renewable energies
are reversible in nature and can constantly replenished without
the fear of been drained out of our environment. Wind energy
for instance is one of the forms of renewable energy; energy is
produced with the help of wind blowing across. It is obvious
that wind is always going to blow across and will not run out
until the last day of earth. It will keep on providing
electricity without any thought of wind to blow off from our
planet. Such energies which can go on to keep producing
electricity without reducing source energy itself is renewable
Sun is the major source of renewable energies
either responsible for direct or indirect source of energies.
Sun light and solar power is direct form of energy which is
received from Sun on massive scale. Solar power technology
provides electricity for homes, office buildings, water heating
or cooling and for various other applications. Sunlight and
its’ heat is indirectly responsible for winds to blow across
our earth. These winds are then blown through wind turbines to
produce electricity; this technique for producing electricity
is known as Wind power.
Sun’s heat and winds makes water
to evaporate which then through natural process falls back on
earth in form of rain water and snow into oceans dams, rivers
etc. We can produce energy with this procedure by using
hydroelectric power. Just as the process of rain goes on it
makes plants to grow, this organic matter which brought up
plants is called biomass. Biomass technology can be used to
producing different useful chemicals, fuels, and electricity.
Using biomass technology to produce any of such products
mentioned above makes it called Bioenergy.
organic compounds present till day and water carries Hydrogen
element. It is known to be the richest element on the face of
the earth; however hydrogen element cannot be found alone in
form of gas in our environment. It is always combined with some
other elements to form some other element. Most common example
known to most of us is hydrogen is combined with oxygen to form
water. When we separate hydrogen element from other element it
can be used as fuel to produce electricity.
other forms of renewable energies which are not majorly caused
by Sun. For instance Geothermal energy, when heat from within
the earth is used for producing energy is called Geothermal
energy and on the other hand gravitational pull of earth and
moon brought up tidal power in oceans and rivers which can be
used to produce electricity, known to be tidal power.
As society becomes more aware of
the need to protect and preserve our planet, many people are
looking at the benefits of renewable energy resources. These
energy sources are the key to a cleaner and greener future.
Traditional energy sources, like oil, cause damage to our
environment through air pollution and waste, which is one of
the main reasons why scientists and researchers are looking at
renewable energy sources. Renewable energy refers to a source
of power harvested from a sustainable and long-lasting source,
such as the sun or wind.
Currently, there are several types of renewable energy
available as alternative energy sources.
Solar power refers to energy harvested from the
sun. Photovoltaic cells draw in heat from the sun, as a form of
kinetic energy. This energy is then transferred to a generator,
which converts it into electricity. These panels can be paired
together on large solar farms to harvest enough energy to power
small towns and neighborhoods, or smaller units of cells placed
on houses to power the lights and electronic devices for that
Wind generates a lot of
clean energy. In a wind farm, large windmills capture the power
of the wind and send the energy to a turbine that converts it
into electricity. Wind power is an easy renewable source of
energy to create and is already in place in many states.
Geothermal energy uses the heat
from the ground. The ground below you collects a lot of heat
during the day, which creates steam. That steam can be captured
by a generator and used to produce power.
Bioenergy, or Biomass, occurs when natural products such
as wood is burned. The burning lets off heat. Humans have used
bioenergy for thousands of years in the form of burning wood to
make fire. Today's biomass is comprised of plants, crops and
even solid waste. Ethanol fuel is also a form of bioenergy
created by breaking down plants into starches and sugars,
fermenting and creating a wood alcohol.
When earth came into being some 4.5 billion years ago there
were no signs of life. Then the symptoms of life came into
being and the development in organism led to the creation of
human being, from the scientific point of view. From the time
when apes transformed into human beings, till now the human
intervention has changed the world so much. The growth of
humans involves a number of mediums, the most vital of which
(after air, water and food) is fuel - fuel to heat their homes,
to cook their food, to run their vehicles, to manufacture
goods, to light up their homes, to run their appliances and
There are two kinds of energy: renewable
energy and non renewable energy. Almost 85 per cent of world
consumption of energy is from non-renewable resources.
Renewable energy is collected from those resources that remain
unaffected even after sacrificing their energy such as solar,
wind, water, etc. These green energy sources are more common in
developing world due to their one time investment. However,
developed nations mainly depend on fossil fuels (petroleum,
natural gas and coal) and nuclear power (fission and fusion).
Non-renewable resources are those resources that once exhausted
can never be returned to their original form.
states are more prompt in utilizing fossil fuels to meet the
needs of their industries. These fossil fuels are a result of
those plants and animals that were partially decomposed and
buried in the crest of earth millions of years ago due to
environmental changes. These fuels have high content of carbon
dioxide and can be feasibly used. Natural gas, coal and oil are
the mostly consumed fossil fuels where oil shells and tar sands
are not used so frequently.
• Coal: The most
abundant form of fossil fuels having an estimated reserve of
one trillion metric tons. Asia, Eastern Europe and United
States are the places where coal is found in abundance. Coal is
burned to acquire heat that is used to convert water into steam
which runs the generators that in turn produce electricity.
Oil: There are a lot of energy products that can be extracted
after refining the liquid petroleum or crude oil such as
heating oil, jet fuels, diesel, gasoline, etc.). More than 50
per cent of the total oil exists in Middle East, where limited
reservoirs are also present in North America. A large part of
discovered oil is already utilized where search of new reserves
is going on (is not putting forth hopeful results). If the
consumption of oil is not controlled today than the remaining
oil of the world will be exhausted in nest 30 years.
Natural Gas: The residue of oil recovery is natural gas. It is
basically a mixture of gases, commonly methane (CH4), ethane
(C2H5), propane (C3H8) and butane (C4H10). The gas does not
contain sulphur and it makes the fuel cleanest. It is called
LPG (Liquid Petroleum Gas) when propane and butane are
detached. Its usage is gaining popularity because it is cheap
and environment friendly. About 100 million metric tons of
natural gas reserves are to date estimate which will last for
approximately 100 years. Middle East and Europe are the biggest
containers of natural gas.
• Oil Shale and Tar Sands: The
utilization of these sources is least. Oil shale contains
Kerogen that is a waxy substance of carbon. On heating to 490
degree centigrade the Kerogen can be vaporized and then
condensed to get shale oil. Abundant energy is required to mine
and process the oil shale. Its reserves are plenty estimated at
three trillion barrels. The world’s requirement of oil for next
100 years can alone be satisfied by consuming these oil shale.
Tar sand contains thick crude oil which cannot be recovered by
conventional oil mining procedures. Steam is used for this
purpose to push and flow the oil swiftly. Canada has the
largest reserve of tar sand and it alone can provide oil
worldwide for about 15 years. These resources are not exploited
mainly due to heavy cost of mining and environmental concerns.
• Nuclear Power: The procedure involves the fission of
uranium particles to produce heat that can convert water into
steam which later on produce electricity. Some of nuclear
reactors are used in United States. It is clean source of
non-renewable energy (no pollutants or green house gases) but
involves threats of mishandling.
No doubt our planet is
full of energy resources but it is our duty to exploit only
those reserves that cannot cause harm to the environment. The
constant consumption of fossil fuels has evolved threats of
fuel extinction but we are provided with many alternates. Need
of the hour is to invent not only cost effective but also
environment friendly methods (to limit the hazardous residues)
to fulfill the increasing demand of power.
