Solar power is the conversion of sunlightinto electricity, through directly usingphotovoltaic (PV). Photovoltaic convertlight into electric current using thephotoelectric effect.
Is Solar Power System Reduce Pollution Effects and Useful? • Reduction in Air Pollution • Health and Safety Concerns • Low Maintenance Cost • Reliable Source3
What is Our Mission? • To Reduce Gaseous emission and thus save the ozone layer. • To Reduce Grid dependency • To Empower remote areas.4
Solar Power System Importance in Pakistan w.r.t Power Resources • Pakistan is currently facing the worst power crisis of its history. • Solar power is best for overcoming energy crisis in Pakistan. • Keeping this factor we seeing that the solar lights at houses and streets are increasing5
Photovoltaic is solid state semiconductor devices that convert sunlight directly into electricity by law of diffusion.6
Movement of molecules/fluid from anarea of higher concentration to an areaof lower concentration is calleddiffusion. Diffusion is a result of thekinetic properties of particles.

1. Where to use the solar system, how about the solar irradiation condition in the area. 2. Total loading power(KW), and daily consumption (KWH). 3. What will be the system output voltage required? 4. Working time on each day for the solar system. 5. System Backup days in continuous raining and cloudy condition.10
Solar Power Projects in Pakistan • On May 29, 2012 The Project titled "Introduction of Clean Energy by Solar Electricity Generation System" of Japan International Cooperation Agency This project can produce 178.08 KW power through Photovoltaic (PV) Solar Systems in Islamabad. • South Korea has shown its interest to install a power plant project of up to 300 MW of solar energy in Quetta, in this regard Memorandum of Understanding (MOU) would be signed with Baluchistan government.12
