How You Can Benefit From Green
Solar Energy
If you have been thinking of
investing in solar panels for your
home, either to save you money on
electricity, to make you secure in the
knowledge that you energy costs are
pegged no matter how much
electricity prices go up. Or, simply
because you wish not to pollute and
emit carbon dioxide and other
pollutants more than necessary in
your own life, you can benefit from
modern solar power collectors.
Now I have found that the idea of going
green in the home may make many
people scratch their heads. It can be
rather confusing and maybe a bit
intimidating; if you are unsure about
what steps can be taken to improve the
way energy is used in your home, read
on to get some information that will
assist you in going green.
Introduction
You will benefit from reading this, by
learning about the following
subjects:
#1. What is the Solar Power
Opportunity Available to All
Homeowners? In this article we explain
the most common uses of solar power,
so that you will appreciate the very
wide scope that exists these days to use
solar electricity to your advantage.
#2. A Deeper Look at Solar Power
and How It Can Help the Average
Homeowner: Before diving further into
the vast number of uses for solar
2
energy, it is important to have a solid
understanding of solar energy itself.
Solar energy is electricity generated by
the Sun's radiation that is absorbed
through square material known as
"solar cells", but that is only the start.
So, read this article for yet more
essential solar information.
#3. How Solar Power Can be a Real
Benefit for Ordinary Homes: Learn
how electricity from the standard grid
suppliers comes from fossil fuels which
are being burned. How to address this
issue is by using solar power for your
home, and how federal and state
governments are now encouraging
many homeowners to utilize solar
power by offering grants and loans. We
make the case for solar power now
being a "must" for most homes. Also,
find out about low cost DIY solar power
kits.
#4. What You Should Know About
Roof-Mounted Solar Cells Before
Buying: Learn how to harness rooftop
solar energy, reduce your electric bill
and limit the amount of carbon dioxide
you add to the atmosphere each day.
Become aware how, depending on
where you live, your roof's orientation,
and the load your roof can bear,
mounting photovoltaic cells (PVs) on
your roof may or may not be a valuable
investment for you, in increasing your
household's energy independence.
#5. Is Solar Power Really as Green as
You Think It Is? It seems as though
with every good thing there is also bad
side. Solar energy is not perfect. We
want you to know about the pitfalls
and the ways in which the sustainability
of solar panels could be jeopardized by
the choice of the wrong manufacturers,
so read this to avoid the environmental
mistakes.

#1. What is the Solar Power Opportunity
Available to All Homeowners?
In this article we expla IPPTS
Associatesin the most common uses of
solar power, so that you will apperciate
the very wide scope that exists these
days to use solar electricity to your
advantage.
If your home has a pool or hot tub, look
into a solar water heating system.
Installing a solar water heating system
costs about the same as a conventional
system, but operating costs for the
system will be much lower. Repair costs
for solar heating systems are often
lower as well.
Remember that solar panels, whether
you install them on your roof or
anywhere else on your property, must
be angled toward the sun to receive
maximum exposure. In the Northern
Hemisphere, this means facing them
south with an angle of latitude plus
fifteen degrees. Otherwise, your
investment will not return as much
4
energy as you hope.
If you are in the process of, or planning
to, design your own home, you can
build some green energy sources right
into your home from the beginning.
Start by looking for land that has a
water source such as a creek or room
for wind turbines. Another good idea is
to choose a roof with solar panels built
in. You can even position them to get
the most out of sunlight.
Use portable solar panels. Small solar
panels are now available for the home,
and some of them are very affordable.
By putting the power of the sun to
work in your home, you will not use as
much electricity to power your devices,
which can save you a good deal of
money.
Consider opting for a solar hot water
heating system. If you must use hot
water to run your dishwasher or do
your laundry, a solar hot water system
can benefit you. If you live in an area
where freezing is not a concern, a direct
circulation system will be perfect for
you.
To reduce your energy consumption
and live a greener lifestyle, consider
purchasing a home which already has
green amenities. For example, an
increasing number of real estate
properties offer windmills, solar panels
or other energy saving or green options
for the socially conscious individual.
Get a jump start on greening your
home by purchasing one which is
already green!
5
Green technology is a growing trend
amongst a lot of people in first world
countries. A lot of people are realizing
at just how much we as humans are
effecting the environment, yet they are
also realizing at just how much we can
contribute and help. There are many
ways you can aid the environment from
doing things like buying an electric car,
changing the light bulbs in your house,
or investing in solar panels for your
home.
You should now be more aware of what
it takes to make your home a green
one. Use the provided information to
reduce the amount of resources that it
takes to run your home. You are sure to
appreciate the changes that you have
made for your lifetime and your
children's.
#2. A Deeper Look at Solar Power and
How It Can Help the Average
Homeowner
Before diving into the vast number of
uses for solar energy, it is important to
have a solid understanding of solar
energy itself. Solar energy is electricity
generated by the Sun's radiation that is
absorbed through square material
known as "solar cells".
To put it simply: the Sun's rays heat up
solar cells, and the heat's energy is
converted into electricity to power
anything from small devices such as
laptop bags to entire buildings.
Four Classes of Solar Energy
There are four major styles of solar
energy: direct, indirect, active and
passive.
Direct solar energy systems convert the
thermal energy once, while indirect
systems convert the energy multiple
times. Active solar means there are
mechanical and electrical parts. Passive
6
systems do not use any mechanical
parts to convert the energy to
electricity.
"So how does solar energy actually
work?"
There are many methods for capturing
the power of the Sun's energy, but the
most common devices are
"Photovoltaic cells". These are
commonly known as solar cell
semiconductors that produce electricity
whenever the external material is
exposed to heat. The cells also naturally
store thermal (heat) energy so the
device the cells are powering can work
when it is dark as well.
Heat from the Sun is absorbed by the
silicon cells and the energy is stored
and converted for use by the
semiconductor inside the cells.
"How can solar energy help me?"
When solar energy cells were first
introduced in 1941 by Russell Ohl,
people hardly realized how this simple
invention could change the World. The
biggest problem with the energy
technique has been the initial cost.
However, while silicon is expensive,
people have been recently turning to
powering their entire house with solar
cells!
Yes, there is a large initial investment,
but by eliminating your electric bill for
the rest of your life, there is a good
chance you'll recoup the loss. Many
people use solar energy to heat their
water (tap, showers, swimming pools,
etc.) without powering their entire
home. This is much cheaper, but it can
still have a positive impact on utility
bills and the environment.
There have been many other smaller
uses, too. In 2006, a small electronics
company invented a solar cell laptop
7
bag that could not only carry your
laptop, but constantly charge it on the
go!
There practically an infinite number of
possibilities for small devices being
charged with solar energy and
eliminating the need for charging every
night for hours just to get a few hours
of use.
As solar cell production costs decrease,
more companies will be able to
produce solar-powered devices and
accessories the public can afford. Either
way, solar energy is a reliable, natural
source of energy that can be used to
power practically anything, and it won't
run out until the Sun does!
#3. How Solar Power Can be a Real
Benefit for Ordinary Homes
‘Going green’ is the trend these days
since the world is facing a lot of
environmental problems specifically
global warming. Electricity comes from
fossil fuels which are being burned. The
emissions contribute a lot to global
warming and one way to address this
issue is by using solar power for homes.
Even the federal and state
governments are now encouraging
many homeowners to utilize solar
power by offering grants and loans.
Solar power is a must for homes and it
is not just for the rich people.
Are you familiar with DIY solar power
kits? The DIY kits are widely available in
online stores and perhaps in local
stores. All you need to do is shop
around and find a suitable system that
can work for your home.
Why is the solar power system a must
for homes?
As mentioned earlier, the government
is also supporting green energy
through grants and loans. Aside from
that, there are also incentives. For
instance, if you spend around $20,000
on system installation, the state
government will give you a 30% credit.
This means that your next tax bill will
decrease by 30% of $20,000 which is
$6,000. The credit can also be extended
to the following year as long as the
amount is covered fully.
8
Once you install the system, it requires
minimum maintenance. Make sure that
you also clean and clear it properly. You
can consult a professional who knows a
great deal about solar power systems
and have yours checked annually. Most
homeowners do little work on their
systems and this is a great advantage.
Sunlight is available for all and since
fossil fuels are depleting, it is an
excellent option. If you install a system
for your home, you will simply need to
invest once and after that, you can now
benefit as long as the system is working
properly. Your electricity bills will surely
be reduced and so you will have
smaller bills every month. You can use
the solar power system for your
outdoor lights, garden lights and
features, and even for indoor use as
long as the inverter is big enough.
Solar panels are one of the most
popular solar power systems used
today. If blackouts are quite common in
your area, it would really help a lot if
you install solar power. That way, even
if other homes don’t have electricity,
your home can still have electricity.
Solar panels are reliable as well as the
other systems available today. Most
manufacturers also provide warranty
and so you can expect the solar panels
to be durable. You won’t hear any noise
since the panels are working quietly
while producing the needed energy.
Electrocution cases are rare since the
photovoltaic cells have low amperage
and are very safe. Power is produced
without emissions or fuel combustions.
Most of all, with solar power systems,
9
you can help in saving the
environment. You can help in
decreasing pollution and the
degradation of the environment. The
power systems can last for decades
with proper maintenance and care. If
you’re interested to go green, don’t
hesitate to install a solar power system
for your home. This is the best time to
make a choice – a choice that can have
a significant impact to the world. After
installation of the system, you can now
enjoy a continuous supply of green
electricity.
#4. What You Should Know About
Roof-Mounted Solar Cells Before Buying
Whenever the sun is out, your home's
roof is exposed to solar energy. Why
not harness that energy, reduce your
electric bill and limit the amount of
carbon dioxide you add to the
atmosphere each day? Depending on
where you live, your roof's orientation,
and the load your roof can bear,
mounting photovoltaic cells (PVs) on
your roof could be a valuable
investment in increasing your
household's energy independence.
What are PVs and how do they work?
Certain materials like gallium arsenide,
crystalline and amorphous silicon, and
copper indium diselenide produce
electricity when they absorb light. This
is called the photoelectric effect. Solar
cells are typically made of a thin layer of
such photosensitive material. Light
hitting the solar cell raises the energy
level of the electrons within. At an
elevated energy state, the electrons are
able to escape from their molecules
and create an electric current.
How can you tell if your roof is a
good candidate for solar cell
installation?
Solar cells work best when exposed to
direct sunlight. Ideally, you could put a
panel of cells on a motorized mount
that follows the sun's path through the
sky, but that's usually not practical for a
roof. The next best thing is a roof
mounting where the pitch has an
unobstructed southern exposure.
Depending on your latitude and the
angle of your roof's pitch, your PV
system installer may suggest
10
optimizing the angle of your PV
modules with an elevated mounting
rack so that they can catch more light.
You also need to be cognizant of how
much weight your roof can bear. If your
roof already has two layers of shingles,
you probably shouldn't add solar
panels to the load.
An alternative to solar panels is a
relatively new product, "solar shingles".
These are shingles into which PV cells
have been incorporated. If your roof
needs to be replaced anyhow, solar
shingles offer the opportunity to kill
two birds with one stone.
Finally, PV cells lose efficiency as the
temperature rises. In warm climates,
you may be better off exploring
alternatives like wind-power. In places
like Florida and California, public
utilities are bringing solar thermal
electric power plants online. Such
systems, though primarily feasible only
for installations much larger than the
single-family home, actually turn out to
be more efficient and cheaper than PV
systems when it's hot.
What components make up a
roof-mounted PV system?
PV cells output direct current, and can
be connected in series to increase the
output voltage. Though there are
specialized appliances available that
run on DC, most PV systems have the
cells send electricity through an
inverter. This converts the solar cells'
DC to standard household alternating
current. The output from the inverter is
then integrated into the house's
electric system. Smaller systems mostly
just supplement power from the
electric company, reducing your overall
bill.
If you install a larger system and make
your home very energy efficient, you
may have often had a surplus of
11
electricity. You can either store this for
later in on-site batteries, or feed it back
to the electric grid. If you feed your
surplus back to the grid, the electric
company may actually pay you. This is
called "net metering", and is the law in
more than thirty-five states. It's a good
deal for you, and it's a good deal for the
electric company because your PV
system is most likely to produce surplus
electricity exactly when peak demand
occurs. Your surplus-producing PV
system could actually help avert power
outages.
How much does a PV system cost?
The initial cost of a roof-mounted solar
array can range from $6,000 for a small
supplementary system to $30,000 or
more for a large "off-the-grid" system.
The capital cost of such a home-based
PV system is rather abstract, though. It
would be better to compare what you
are currently paying per kilowatt-hour
to an amortized per kilowatt-hour cost
for a PV system. According to the U. S.
Department of Energy, that cost is
about $0.25 per kilowatt-hour. In most
places, this is more than what the
utilities charge.
That's the bad news.
The good news is that there are many
state-sponsored incentive programs for
solar energy. Take advantage of them,
and you could break even. For
information about these programs, you
should consult the National Database
of State Incentives for Renewable
Energy (DSIRE), prepared by the North
Carolina Solar Center. The database
covers incentive programs meant to
promote the development of
renewable energy.
In addition, the cost of the electricity
your PV system produces is insulated
from deregulation, rate-hikes, and
inflation, that amortized twenty-five
12
cents per kilowatt-hour cost will still be
twenty-five cents thirty years from now.
Who knows what your local electric rate
will be?
And there's more good news. By going
solar, you are reducing the amount of
coal and natural gas burned at power
plants, you are reducing the amount of
carbon dioxide we pump into the
atmosphere, and you are asserting your
energy independence.
Putting solar cells on your roof is an
idea whose time has come.
Home-produced solar electricity is
feasible, makes sense, and is within the
reach of most homeowners.
#5. Is Solar Power Really as Green as
You Think It Is?
It seems as though with every good
thing there is a bad side. Such is the the
case with solar energy. Solar energy is
destined to be the next super star in the
quest for renewable energy. On the
surface solar energy appears to be the
solution to our world's energy crisis, but
what is not obvious is the dark side to
solar energy. The manufacturing
process of solar panels uses a large
amount of fossil fuels and the cells in
solar panels contain toxic materials
which are not readily recycled.
Environmentalists are concerned that
this new technology will pour
hazardous wastes into or landfills when
these panels start to wear out.
Standards need to be set today that
deal with the end of life of these solar
panels. We certainly do not want a
whole new industry that continues to
pollute our planet.
It is critical that this new technology,
which has so much promise for the
future, be completely green from start
to finish. We cannot afford to make the
same mistakes that we made with the
electronics industry. e-Waste is a major
problem around the world. Improper
disposal of cell phones, computers,
printers and other electronic waste is
filling the landfills with hazardous and
toxic materials in a big way. Solar
energy technology should not take that
same route.
13
The solar industry is only in its infancy
and accounts for only a minute amount
of the power needed to run this planet.
This is set to change. The newly elected
President of the United States,
promises to get the country on the
right track to ends its dependency, on
not only foreign oil, but oil all together.
The problem with pushing this
technology is that countries such as
China are using horrific manufacturing
practices to supply components for
solar power products. Story after story
is being reported about the
contamination of the soil, water and air
in China, all from the improper
dumping of toxic chemicals.
Low paid workers, many of whom are
children, are dying, developing cancers
and suffering from all sorts of diseases
due to the manufacturing practices
used today.
It is critical that as technology
progresses, materials must be used that
do not harm the environment. It is
important to have a disposal plan in
place when these units wear out or are
replaced with new technology.
Many manufacturing companies want
to "do the right thing", and are working
together to develop ideas on how to
recycle solar panels before they
become an environmental hazard.
These companies do not want to deal
with rules and regulations that may be
passed in the future, and are willing to
take responsibility for the entire life and
death of their products.
Some companies have gone so far as to
set up private trust funds to cover the
cost of the collection efforts. This will
ensure that the panels will be recycled
even if the company goes out of
business.
So make sure that you only buy your
14
solar panels from companies that
provide solutions to the energy
problem and not create environmental
hazards. Providing we all ask those
questions in our quest for genuinely
sustainable renewable energy, we will
not go far wrong.

SPECIAL REPORT:
Is It Possible To Stop Paying For
Electricity By Using Solar And Wind
Power That Is Available For FREE?,
Without Anyone Else Tricking You Into
Thinking That A Home Energy
Generator Is Expensive... The fact is that
you Could Go "Off Grid", Or Even Have
The Electric Company Pay YOU...?
15
According to David Knight, a
self-employed home energy expert
for the last 8 years, who has made a
large number of renewable systems
for clients that wanted to get energy
for free and save a lot of money, and
owner of the popular :
DIYPowerSystem website the answer
is yes!
"When I started people said that a
Home Energy Generator was too
expensive... they said that I would
not be able to go "Off Grid" but I did
it David Knight, and I continue to do
it for very many clients, he tells us.
Why most people struggle with paying
for energy..
According to David Knight, there's a
reason why so many people struggle
with saving on their energy bills
despite so much help being offered
to them today...
"There are so many interested in
keeping the energy industry as it is
today, that they will never give out the
help you need on a plate. I am a fanatic
reader of all sorts of magazines that
show people the tech details behind
renewable energy systems. Using tons
of books, magazines and instructions I
was able to build my own systems and
even my home."
"Then, and for the last 8 years, I have
been making tons of renewable
systems for clients that wanted to get
energy for free and save a lot of money.
And this was very successful. Clients
were very happy that they kept sending
more clients. Eventually, I got to a point
that people were flooding my doors in
order to build systems for them. But, I
16
realized that if I wanted to help more
people I would need to write down the
instructions on how I do it. That was
how this product was born"
How David Knight conquered his
energy bill problem with a unique
approach, and says he can solve your
too.
"Discover How To Build Your Own Wind
Or Solar Energy Generator For As Little
As $100! And This Is *Only* The
Beginning...", David Knight tells us.
David Knight focuses on the unique
approach he has developed through
years od study, trial and error, to solve
his own and other people's need for
energy cost savings.
We asked ourselves was it worth it? We
think that the following testimonials
speak for themselves...
"So Easy To Build By Virtually Anyone.
I’ve never encountered a renewable
energy generator that is so clearly
described and so easy to build by
virtually anyone. I’ll probably introduce
this to my students in my classes as
homework" - Ionadi Chim, Sydney, AU
And Ionadi Chim is not alone. There are
many success stories that you can read
