What is Solar Power?

Solar power is energy from the sun, and without its presence all life
on earth would end. Solar energy has been looked upon as a serious
source of energy for many years because of the vast amounts of
energy that are made freely available, if harnessed by modern
technology.

A simple example of the power of the sun can be seen by using a
magnifying glass to focus the sun’s rays on a piece of paper. Before
long the paper ignites into flames.






Uses of Solar Energy

We have always used
solar energy

as far back as humans have existed
on this planet. We know today, that there are multiple uses of solar
energy. We use the solar energy every day in many different ways.
When we hang laundry outside to dry in the sun, we are using the solar
heat to do work, drying our clothes. Plants use the solar light to make
food. Animals eat plants for food. And as we learned, decaying plants
hundreds of millions of years ago produced the coal, oil and natural gas
that we use today.










METHODS TO HARNESS SOLAR ENERGY

Very often there is confusion about the various methods used to
harness
solar energy
.

Energy

from the sun can be categorized in two ways:

METHOD 1: IN THE FORM OF HEAT (OR
THERMAL ENERGY)
















METHOD 2: IN THE FORM OF LIGHT ENERGY


Light energy can be

defined as The

electromagnetic radiation

of visible light. Since light

Itself is energy, then

another definition is relevant:

light is nature’s way of transferring Energy

through space.






HOW TO COLLECT THE
ENERGY FROM THE SUN?

Solar

thermal

technologies

uses

the

solar

heat

energy

to

heat

substances

(such

as

water

or

air)

for

applications

such

as

space

heating,

pool

heating

and

water

heating

for

homes

and

businesses
.

There

are

a

variety

of

products

on

the

market

that

uses

solar

thermal

energy
.

Often

the

products

used

for

this

application

are

called

solar

thermal

collectors

and

can

be

mounted

on

the

roof

of

a

building

or

in

some

other

sunny

location
.




CONVERTING SOLAR

ENERGY INTO ELECTRICAL


ENERGY


The

solar

heat

can

also

be

used

to


produce

electricity

on

a

large


utility
-
scale

by

converting

the


Solar

Energy

Into

mechanical


energy
.

So,

fossil

fuels

is

actually


solar

energy

stored

millions

and


millions

of

years

ago
.

Indirectly,

the

sun

or

other

are

responsible

for

all

our

energy
.

Even

nuclear

energy

comes

from

a

star

because

the

uranium

atoms

used

in

nuclear

energy

were

created

in

the

fury

of

a

nova

-

a

star

exploding
.

Let's

look

at

ways

in

which

we

can

use

the

solar

energy
.





1. RESIDENTIAL


The

number

of

PV

installations

on


Buildings

connected

to

the

electricity


grid

has

grown

in

recent

years
.


Government

subsidy

programs


(particularly

in

Germany

and

Japan)

and


Green

pricing

policies

of

utilities

or

electricity

service

providers

have

stimulated

demand
.

Demand

is

also

driven

by

the

desire

of

individuals

or

companies

to

obtain

their

electricity

from

a

clean,

non
-
polluting,

renewable

source
.

These

consumers

are

usually

willing

to

pay

only

a

small

premium

for

renewable

energy
.

Increasingly,

the

incentive

is

an

attractive

financial

return

on

the

investment

through

the

sale

of

solar

electricity

at

premium

feed
-
in

tariff

rates
.






USES OF SOLAR ENERGY


2. COMMERCIAL



On

an

office

building,

roof

areas

can

be


covered

with

glass

PV

modules,

which

can

e


semi
-
transparent

to

provide

shaded

light
.

On


a

factory

or

warehouse,

large

roof

areas

are



the

best

location

for

solar

modules
.

If

the

roof

is

flat,

then

arrays

can

be

mounted

using

techniques

that

do

not

breach

the

weatherproofed

roof

membrane
.

Also,

skylights

can

be

partially

covered

with

PV
.


The

vertical

walls

of

office

buildings

provide

several

opportunities

for

PV

incorporation,

as

well

as

sunshades

or

balconies

incorporating

a

PV

system
.

Sunshades

may

have

the

PV

system

mounted

externally

to

the

building,

or

have

PV

cells

specially

mounted

between

glass

sheets

comprising

the

window
.





3. INDUSTRIAL









For

many

years,

solar

energy

has

been

the

power

supply

choice

for

industrial

applications,

especially

where

power

is

required

at

remote

locations
.

Because

solar

systems

are

highly

reliable

and

require

little

maintenance,

they

are

ideal

in

distant

or

isolated

places
.

Solar

energy

is

also

frequently

used

for

transportation

signaling,

such

as

offshore

navigation

buoys,

lighthouses,

aircraft

warning

light

structures,

and

increasingly

in

road

traffic

warning

signals
.

Solar

is

used

to

power

environmental

monitoring

equipment

and

corrosion

protection

systems

for

pipelines,

well
-
heads,

bridges,

and

other

structures
.

For

larger

electrical

loads,

it

can

be

cost
-
effective

to

configure

a

hybrid

power

system

that

links

the

PV

with

a

small

diesel

generator
.


4. REMOTE APPLICATION


Remote buildings, such as schools,

Community halls, and clinics, can benefit

from solar energy. In developing regions,

central power plants can provide electricity

to homes via a local wired network, or act as a battery charging station

Where members of the community can bring batteries to be recharged.
(e.g.
of Indian Oil Solar lantern ref. next 2 slides)
PV systems can be
used to pump water in remote areas as part of a portable water supply
system. Specialized solar water pumps are designed for submersible
use or to float on open water. Large
-
scale desalination plants can also
be PV powered using an array of PV modules with battery storage. PV
systems are sometimes best configured with a small diesel generator in
order to meet heavy power requirements in off
-
grid locations. With a
small diesel generator, the PV system does not have to be sized to cope
with the worst sunlight conditions during the year. The diesel generator
can provide back
-
up power that is minimized during the sunniest part of
the year by the PV system. This keeps fuel and maintenance costs low.

Top 10 countries

Modern times. With pollution breathing

Heavy on the present civilisation, it just

cannot do without wind and solar energy.

Countries across the world have geared up to develop alternative
energy sources for better living. India is densely populated and has
high solar insolation, an ideal combination for using solar power.
However, on the world map, India lags far behind other countries as
far as generation of

solar power is concerned, although the country
has made significant progress in wind energy generation. In July 2009,
India unveiled a $19
-
billion plan to produce 20 GW of solar power by
2020. Under the plan, the use of solar
-
powered equipment and
applications would be made compulsory in all government buildings,
as well as hospitals and hotels.

Let us take a look at the top 10 countries using solar power:

1.
Germany

Total use: 10,000 megawatts

Germany

is

the

world

leader

in

solar

energy
.

Germany


is

expected

to

stay

the

top

buyer

of

solar

panels


through

2011
.

Germany

has

a

goal

of

100

per

cent


renewable

energy

by

2050
.

In

2009

alone,

Germany


installed

3
,
806

megawatts

of

photovoltaics

solar

energy


capacity,

which

is

more

than

Spain's

total

capacity

and

almost

eight

times

more

than

what

the

US

installed

recently
.



2. Spain

Total use: 3,500 MW

Spain

was

the

world

leader

in

newly

installed

PV

solar

energy

(
2
,
605

MW)

in

2008

but

its

new

installed

capacity

decreased

tremendously

(to

just

69

MW)

in

2009
.

The

reasons

for

this

drop

are

attributed

to

complexity

and

delays

related

to

a

new

government

subsidy

programme

and

a

decrease

in

energy

demand

due

to

the

economic

crisis
.

With

expectations

that

both

of

these

will

improve

in

and

considering

its

excellent

sun

irradiation

and

PV

potential,

Spain

is

expected

to

bump

up

its

solar

energy

capacity

again

this

year
.

3. Japan

Total use: 2,700 MW

Japan has high national solar energy goal's to achieve 28 GW by 2020 and 53
GW by 2030. Japan invested $9 billion in stimulus money in solar energy in
2009, and the prime minister also announced a plan to install solar power at
32,000 public schools that year.


4. United States


Total use: 1,800 MW

Supportive state
-
level policies are a major driver

of growth of solar energy in the US. With many

large ground
-
mounted solar projects in the

pipeline, installed capacity in the US is expected to grow significantly in coming
years. The cap on the federal solar tax credit was lifted in 2009, promoting
growth in this industry.


5. Italy
-

Total use: 1,300 MW

In 2009, Italy had experienced the second
-
largest solar energy growth in the
world. Every two months, Italians install more solar power than California does
in an entire year.

6. Czech Republic
-

Total use: 600 MW

A

generous

FiT

and

simple

administrative

procedures

have

put

the

Czech

Republic

on

this

list
.

The

market

growth

has

probably

boomed

unsustainably,

however,

and

if

appropriate

policies

aren't

put

in

place

to

slow

it,

the

nascent

solar

bubble

is

expected

to

bust

in

the

coming

years
.

7. Belgium
-

Total use: 450 MW

Belgium

is

a

bit

of

a

2011

solar

energy

surprise
.

Belgium's

success

was

from

'a

well
-
designed

Green

Certificates

scheme

(which

actually

works

as

a

Feed
-
in

Tariff),

combined

with

additional

tax

rebates

and

electricity

self
-
consumption
.
'


8. China
-

Total use: 400 MW

China

gets

a

lot

of

attention

these

days

for

its

clean

energy

push,

and

for

good

reason
.

China

is

a

major

solar

panel

manufacturer

but

hasn't

installed

a

ton

of

PV

itself

yet
.

However,

it

now

has

12

Gigawatts

of

large

projects

in

the

pipeline

and

if

those

projects

are

implemented

China

is

expected

to

jump

closer

to

the

top

of

the

list
.

According

to

China's

national

energy

plan,

it

is

expected

to

reach

a

total

of

20

GW

by

2020
.

According

to

a

recent

PTI

report,

China

is

marching

well

ahead

of

all

of

them

when

it

comes

to

capturing

the

solar

market
.

China's

solar

energy

budget

still

stands

roughly

20

times

larger

than

America's

investment

in

the

same

period,

Jonathan

Silver,

executive

director,

Department

of

Energy

told

US

lawmakers

recently
.

.

France

-

Total

use
:

350

MW


France

has

a

well
-
designed

FiT

for

building
-
integrated

photovoltaics
,

so

BIPV

dominates

the

market

there
.

They've

put

protections

in

place

to

help

avoid

abuse

of

the

system,

and

may

revise

the

tariffs

to

accompany

price

speculations
.

One

key

issue

of

concern

in

France

is

that

although

many

MW

of

solar

energy

have

been

installed,

a

lot

of

them

have

not

been

connected

to

the

grid
.

In

2009
,

285

MW

of

capacity

was

installed

but

only

185

MW

connected

to

the

grid
.

This

is

a

major

issue

that

needs

to

be

resolved
.

When selecting a solar contractor here are some key things to look for:

1.
General Experience

-

How many years experience does the company have in
installing renewable solar energy systems.


Solar is a growing area and many
contractors have limited track records.

2.
Local Experience

-

Has the contractor done solar homes in your local area.


The
closer the better. See if any of those homes might allow you to talk to the owner.

3.
Licensing

-

Is the contractor licensed in your county and are they familiar with state
and local building regulations that impact solar installations.

4.
Certifications

-

Does the contractor have any specific manufacturer or industry
certifications.

5.
References

-

References are invaluable, particularly if they reflect local work that is
similar to what you plan to do.


Don't rely just on written references because too often
these might be from family or friends.


Get references you can call and then don't be
shy about calling. That is often the best way to get the real scoop on a contractor.

6.
Knowledge of Incentives

-

Most states and some local governments provide a
number of financial incentives for solar systems. These can make a huge difference in
the cost of your solar energy system.


Find out if the contractor you are considering is
familiar with these incentives.


Moreover, find out if they will apply for the financial
incentives for you as part of their package.

7.
Warranties

-

The best contractors warranty their work.


When comparing bidders
look to see who provides the strongest warranty. Check the fine print!


Solar Energy is widely viewed as a ray of
hope in a world that is being rapidly
degraded by pollution and deforestation.
Tapping energy provided by the sun, Tata
BP Solar has been showing the way with a
range of non
-
polluting, environment
-
friendly technologies and systems that offer
not only reliable energy, but also hope for a
better future.
