2. INTRODUSTION
Solar energy is the energy obtaind by capturing heat and light from the
sunEnergy from sun is referred to as solar energyTechology has provide
d a number of way to utilize this abundant resourseIt is cosiderd a green
technology because it done not emit green houseGases solar energy is
abundantly avilable and has been utilized since long botAs clectrical and
source of heat
Active solar
Active solar techniques include the use of photovolatic systems
conentraid solarpower and solar water heating to harness energy .
Active solar is directly consumed inactive such as drying clothes and
warming of air
Passive solar
Passive solar techniques include orienting a building to the sun selecting
material withfavorable thermal mass or light-dispersing properties and
desiging space thatnaturally circulate air.

3. Solar power is the converison of energy from sunlight into electircalcity
either directlyUsing photovoltaics . Indirectly using concentrated solar
power or a combaitionconventrated solar poer system use lensesor
mirrors and tracking system to focus alarge area of sunlight into a small
Solar technology isn’t new. Its history spans
from the 7th
Century B.C. to today. We started out concentrating the
sun’s heat with glass and mirrors to light fires.

4. Today, wehave everything from solar-powered buildings to
solarpoweredvehicles.Here you can learn more about the milestones in
thehistorical development of solar technology, century bycentury, and
year by year. You can also glimpse the future.This timeline lists the
milestones in the historical developmentof solar technology

5. SOLAR ENERGY
Every day, the sun radiates (sends out) an enormous amountof

6. energy
—
called solar energy. It radiates more energy in one daythan the world
uses in one year. This energy comes from within thesun itself.Like most
stars, the sun is a big gas ball made up mostly of hydrogenand helium
gas. The sun makes energy in its inner core in a processcalled nuclear
fusion.
It takes the sun’s energy just a little over eight minutes to travel the
93 million miles to Earth. Solar energy travels at the speed of light,
or186,000 miles per second, or 3.0 x 108 meters per second.Only a
small part of the visible radiant energy (light) that thesun emits into
space ever reaches the Earth, but that is more thanenough to supply all
our energy needs. Every hour enough solarenergy reaches the Earth to
supply our nation
’s energy needs for a
year! Solar energy is considered a renewable energy source due tothis
fact.

7. SOLAR WATER HEATINGSolar energy can be used to heat water.
Heating water for bathing,dishwashing, and clothes washing is the
second largest homeenergy cost. Installing a solar water heater can
reduce your waterheating bill by as much as 50 percent.A solar water
heater works a lot like solar space heating. In ourhemisphere, a solar
collector is mounted on the south side of a

8. roof where it can capture sunlight. The sunlight heats water in a tank.
just as it would be with an ordinary water heaterSOLAR PANELSolar
panel sunlight as source of energy to generate electricityA photovolting
module is a packaged connected assembly of typicaly photovolting solar
cellsPhotovolting module constitute the photovolting arry of
aphotovolting system that generate and supplies solar electricityin
commrerical and residential applicatonThe most common aplication of
solar energy collection outsideagriculture is solar water heating system

9. PHOTOVOLTAIC POWER SYSTEM

10. Photovoltaic (PV) technology converts one form of energy(sunlight) into
another form of energy (electricity)using nomoving parts, consuming no
conventional fossil fuels, creating nopollution, and lasting for
decadeswith very little maintenance.The use of a widely available and
reasonably reliable fuel source
—
the sun
—
withno associated storage or transportation difficultiesand no emissions
makes this technology eminentlypracticable forpowering remote
scientific research platforms. Indeed, numerousexamples of
successfullydeployed systems are already available.The completely
scaleable nature of the technology also lendsitself wellto varying power
requirements
–
from the smallestautonomous research platforms to infrastructure-
basedsystems.This technology can be limited, however, by annual
fluctuationsin solar insolation, especially atextreme latitudes.Based on
semiconductor technology, solar cells operate on theprinciple that
electricity will flow between twosemiconductors when they are put into
contact with each other and exposed tolight (photons).
Thisphenomenon, known as the photovoltaiceffect, was first discovered
by Edmund Becquerel in 1839.Actualdevelopment of PV technology
began in the 1950s andgained greater impetus through the NASA
spaceprogram during the 1960s. Research continues today at national
laboratories and within private industry,focusing on increasing
conversionefficiencies and mass production strategies to further lower
thecost ofproducing PV modules.

11. SOLAR PHONE CHARGER
Solar phone charger use solar panel to charge cell phone batteriesThey
are an alternative to conventiona electrical cell phonecharger and in
some cases can be plugged into an electrical outletThere are also public
solar charger for mobile phones which can be installed permanently in
public places such as streets park andsquares .

12. Some model of cell phone have a built in solar charger and
arecommercially available for gsm cellphone model .Solar cell phone
charger come in different shapes andconfiguration including fplding and
roting types .* specification of chargerUse high efficiency
monocrystalline siliconSplar panel 5.5 v/1000mAOutput voltage
5.5vOutput current 300-550 mA

13. CONCLUSION
We had a awesome week oriting around the solar system and iphone
and hope you all have lerned a lot.I hope you have enjoyed lerning this
week as a group we willdiscuss our finding as we orbited around the
solar system .Saving of land this project is very successful oneThe extra
enrgy can be provided to the gridWhat you favorite part of the lesson
?Did you enjoy working with your partenr ?Did you lerning anything new
that surprised you ?Which planet did you enjoy lerning about ?You will
be completing a solar system with the art techer nex weekPlease click
on the link bilow to gate lock at solar system butFeel free to design your
oen and creating with it
