  3. 3. Energy crises in Pakistan what are the solutions? Why we use solar energy? Electricity Rates Pakistan is sunshine state Introduction to solar Energy What is a Photovoltaic Cell? Types of PV Basic parts of PV solar system What is Solar thermal? Solar plants all over the world. Solar in Pakistan at present Domestic and Agriculture Packages Future Plans Contents 3
  4. 4. Energy Crisis in Pakistan  The shortfall of electricity has reached 3220 mega watt (MW), while electricity production has remained 9630 MW.  Due to the increasing shortfall, the unannounced load-shedding hours have increased manifold.  In urban areas people face 6 to 8 hours load-shedding while in rural areas the power supply cut has reached more than 10 to 14 hours. (increase in Peak demand season)  The current demand of electricity is 12,850 MW, while hydro power production is 2820 MW; thermal resources produce 1800 MW; production through independent power producers (IIPs) is 5030 MW, which amounts total production of 9630 MW
  5. 5. Solutions??? Hydro power plant + No need to burn fuel + Environment friendly - Costly - Less availability of water - Install far away from load center - High transmission cost and losses Fossil fuels - Very costly - Maintenance cost - Harm full for your environment Nuclear power plant + High energy source + One time investment + Long life - Costly - Dangerous due to radiation - Radioactive waste Solar power + No need to burn fuel + One time investment + long life - Produce energy only in day time
  6. 6. Cost saving Improved availability and quality of power Environmental friendly Start with small system and expand it over time Long life Insulates roof from direct sunlight Good efficiency Job opportunities Peace of mind Good solution for remote areas Why we use Solar Energy??

  17. 17. In solar thermal we use the heat of sun to generate electrical energy It is called CSP (concentrated solar power) • Parabolic Trough Uses mirrors to focus sun light on a receiver glass tube a liquid flows through the pipes that takes energy to the steam generator Solar Thermal http://www.treehugger.com/parabolic-trough-technology-1.jpg http://www1.eere.energy.gov/solar/linear_concentr ators.html
