- Solar power involves converting sunlight into electricity through photovoltaic cells or concentrated solar power. - Pakistan receives high solar radiation throughout the year, especially in remote areas not connected to the national power grid, making solar power feasible. - Advantages of solar power in Pakistan include a free power source, no pollution, and suitability for remote areas, while disadvantages are high initial costs and reliance on sunlight. - Several solar power plants currently operate in Pakistan and the government is promoting expansion through land allocation projects.

- 2. WHAT IS SOLAR POWER?? SOLAR POWER IS THE CONVERSION OF SUNLIGHT INTO ELECTRICITY EITHER DIRECTLY BY USING PHOTO VALTAICS OR CONCENTRATED SOLAR POWER. A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect.
- 3. 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 ECONOMICALLY VIABLE TO CONNECT THESE VILLAGES TO THE GRID.
- 4. SOLAR ENERGY HAS GREAT POTENTIAL IN AREAS OF PAKISTAN THAT RECEIVE HIGH SOLAR RADIATION THROUGHOUT THEYEAR. FOR EG. 19 MEGA JOULES OF SOLAR ENERGY PER SQUARE METRE, IS RECEIVED BY THE COUNTRY EVERYDAY THE NATION WIDE AVERAGE IS 5.5KWH/METRE SQ./DAY Enough energy potential for solar energy because there are 250-300 sunny days per year. Continuous cloudy days are rare.
- 5. ADVANTAGES OF SOLAR POWER DEVELOPMENT TO PAKISTAN The power source of the sun is absolutely free. The production of solar energy produces no pollution. The technological advancements in solar energy systems have made them extremely cost effective. Most systems do not require any maintenance during their lifespan, which means you never have to put money into them.
- 6. Solar energy systems are now designed for particular needs. For instance, you can convert your outdoor lighting to solar. The solar cells are directly on the lights and can’t be seen by anyone. At the same time, you eliminate all costs associated with running your outdoor lighting. Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. It is estimated that the worlds oil reserves will last for 30 to 40 years. On the other hand, solar energy is infinite (forever). Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid.
- 7. Solar cells are long lasting sources of energy which can be used almost anywhere. Solar cells are also totally silent
- 8. DISADVANTAGES OF SOLAR POWER Initial Cost : The initial cost of purchasing and installing solar panels always become the first disadvantage. Although subsidy programs, tax initiatives and rebate incentives are given by government to promote the use of solar panels we are still way behind in making full and efficient use of solar energy.
- 9. LOCATION: The location of solar panels is of major importance in the generation of electricity. Areas which remains mostly cloudy and foggy will produce electricity but at a reduced rate and may require more panels to generate enough electricity homes. Houses which are covered by trees, landscapes or other buildings may not be suitable enough to produce solar power.
- 10. POLLUTION: Most of the photovoltaic panels are made up of silicon and other toxic metals like mercury, lead and cadmium. Pollution in the environment can also degrade the quality and efficiency of photovoltaic cells. New innovative technologies can overcome the worst of these effects. RELIABILITY: Unlike other renewable source which can also be operated during night, solar panels prove to be useless during night which means you have to depend on the local utility grid to draw power in the night.
- 11. INEFFICIENCY: Since not all the light from the sun is absorbed by the solar panels therefore most solar panels have a 40% efficiency rate which means 60% of the sunlight gets wasted and is not harnessed. INSTALLATION AREAS: For home users, a solar energy installation may not require huge space but for big companies, a large area is required for the system to be efficient in providing a source of electricity.

- 14. FUTURE PROSPECTS Pakistan has a lot of potential especially in northern Baluchistan. It could also lead to development in that area. As well as a supply of electricity in Baluchistan which is presently lacking can be established. So the production of solar power is beneficial for Baluchistan.
- 15. Recently the Punjab government has decided to allocate 5,000 acres of land for private solar power projects in the Cholistan which will be allotted to solar power sector investors at a nominal rate of one dollar per acre per year for a 20-year lease. Out of 5,000 acres of land, 2,500 acre land is situated in Maroot, Bahawalnagar and the rest of 2,500 acres land is located on Din Garh Road, Yazman, Bahawalpur.
- 16. California currently has the largest solar power plant in the world. Covering 1000 acres are nine solar thermal plants in the Mojave Desert.
