WHAT IS SOLAR ENERGY?SOLAR POWER IS THE CONVERSION OF SUNLIGHT INTO ELECTRICITY EITHER DIRECTLY BY USING PHOTO VALTAICS.

Photovoltaic cell (PV):

A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect.

.

WHAT IS SOLAR ENERGY?

The most precise Solar Energy definition : Energy from the sun. But what is solar energy really? There are two types of solar energy:1)Thermal Energy  2)Electric Energy

Thermal Energy: Thermal Energy is everywhere. It’s lights up our days. It heats the earth, our bodies and our homes. It dries our clothes . All for free! Electric Energy: Electric Energy uses the power of the sun to produce electricity through solar cells, otherwise known as Photovoltaics (PV).

Distance from earth: 1.495E11 m (93 million miles) ± 1.7%

Powered:Powered by hydrogen fusion

Composed of layers. The outer layer is the photosphere

Temperature Effective blackbody temperature of of 5777 K

WHAT IS THE FEASIBILITY OF DEVELOPING SOLAR POWER IN PAKISTAN?

IN PAKISTAN, ABOUT 70% OF THE POPULATION LIVES IN SOME 50,000 VILLAGES DISPERSED AROUND THE COUNTRY.

MANY OF THESE VILLAGES ARE FAR FROM THE MAIN TRANSMISSION LINES OF THE NATIONAL GRID BECAUSE OF THEIR RELATIVELY SMALL POPULATIONS.

IT IS NOT USUALLY ECONOMICAL TO CONNECT THESE VILLAGES TO THE GRID.

CONTINUED…..

SOLAR ENERGY HAS GREAT POTENTIAL IN AREAS OF PAKISTAN THAT RECEIVE HIGH SOLAR RADIATION THROUGHOUT THEYEAR.

ENOUGH ENERGY POTENTIAL FOR SOLAR ENERGY BECAUSE THERE ARE 250-300 SUNNY DAYS PER YEAR.

CONTINUOUS CLOUDY DAYS ARE RARE.

FUTURE PROSPECTS IN PAKISTAN

Pakistan has a lot of potential especially in northern Baluchistan.

A Memorandum signed between the Balochistan government and CK Solar Korea for installing a 300 MW solar power plant near Quetta.

Punjab govt launches solar power project in Cholistan.

Over 2000 workers from Pakistan and China are working hard to build the world’s largest solar park, Quaid-e-Azam Solar Park.

Once completed, the 1,000 MW solar park is expected to provide electricity to approximately 320,000 households.

Longyangxia dam solar park,China currently has the largest solar power plant in the world.
