1 Naveed Iqbal Akhter Solar Ltd Photovoltaic Technology. How PV help in energy crisis

2 ENERGY USE Worldwide Energy Consumption

3 Where does our energy come from? Share of total Primary Energy Supply in ,376 Mtoe IEA Energy Statistics

4 ELECTRICITY - Energy used for Electricity Generation by Fuel Type, 2003, 2015, 2030

5 35.6% 41.6% Increasing percentage of Total World Energy used for Electricity Generation Quadrillion BTU Electricity is becoming more important

6 Focus on Electricity World Electricity Generation by Fuel

7 Focus on Electricity Sources of Electricity in Pakistan

8 Sector wise distribution of Electricity Focus on Electricity

9 ENERGY PRODUCTION Fossil fuels Electricity consumption increase +100% between 2003 – 2030 Main fuel type : Natural gas and Oil Reserves are running out + Demand outstripping supply Prices are rising Oil, 400 Gas, 250 Coal, 100 Coal, 35% Gas, 20% RE, 18% Nuclear, 17% Oil, 10% Coal Gas Oil 260 yrs 70 yrs 50 yrs Emission of CO2 Million metric tones equivalent Increase of temperature causing climate change 14/02/20149 Need sources of data

10 Supply and Demand of Electricity in Pakistan Supply and Demand Position: (MW) Existing Generation 15,903 Proposal / Committed Generation 5304,2357,22610,11510,55613,30713,52014,60716,13418,448 Total Existing/Commi tted Generation 16,48420,13823,12926,01826,45929,21029,42330,51032,03734,351 Expected Available Generation 13,14616,11018,50320,81421,16723,36823,53824,40825,63027,481 Demand (Summer Peak) 16,48417,86819,35220,87422,46024,12625,91928,02930,22335,50434,91837,90741,132 Surplus/Deficit Generation -3,338-1, , ,381-3,621-4,593-8,023-7,437-10,426-13,651 Source: Private Power and Infrastructure Board - Govt. of Pakistan Electricity Deficiency chart Supply and Demand of Electricity in Pakistan

11 Core Issues of Electricity in Pakistan 45% Population without Electricity Demand and Supply Gap Expensive Sources of Electricity

12 Expensive Installation Expensive Distribution Ultimate Solution Standalone Solar Home System

13 PV Power Plants Generate enough electricity to provide Homes Revenue stream commences from 7 th month of start of project Commercially Feasible at tariff of 18cent/KWh or 15 cent/KWh at an increment of 2% per annum for 20 years Required Loan at soft interest rate of 2% Land Cost should be very nominal Capital investment required:- 35 M US $ for 10 MW capacity

14 PV Power Plants Generate enough electricity to provide Homes Revenue stream commences from 7 th month of start of project Commercially Feasible at tariff of 18cent/KWh or 15 cent/KWh at an increment of 2% per annum for 20 years Required Loan at soft interest rate of 2% Land Cost should be very nominal Capital investment required:- 35 M US $ for 10 MW capacity

15 Net Metering Incentive for consumer investment in PV generation system Low Cost easy administered Required arrangement with local electricity provider instead of state Feed in tariff required to announce. Net metering is connection of small renewable energy generating system to Grid

18 Population Without Electricity More than 45% population without Electricity.

19 19 Current 2010 Revised Plan 2030 Primary Energy Mix

20 The Future Is Bright Example of cost recovery on an installation amortised over 25 years. Assumes an increase in fossil fuel costs of 5% pa. PV generated per kwh Fossil generated per kwh

21 Solar Energy How much is available? The suns rays provide enough energy to supply 10,000 times the TOTAL energy requirement of mankind. So, how do we harness it? Solar Thermal Photovoltaic The ULTIMATE source.

22 Photovoltaic Possible materials to make PV cells CiGs Copper Indium Gallium Diselenide Polymers CdTe Cadmium Telluride Silicon Amorphous Thin Film Mono crystalline Multi crystalline Solar power market share by technology

23 The Chain Metallurgical Grade Silicon Electronic Grade Chunks Ingot Bars Wafers Modules Sand Strings Cells

24 Market Size By 2010, there is realistic potential for $30bn in solar power system sales

25 Production Cost Improvements Thinner wafers mean greater efficiency in price AND performance

26 Cost Breakdown Produced in Low labour cost area 10.5 % 2.6 % 8.9 % 78 % (Labour cost $2/hour)

27 Cost Breakdown Produced in High labour cost area 9%9% 12 % 10 % 71 % (Labour cost $10/hour)

28 Price Trend Estimate of global average solar module prices US$/watt

29 Viability Over 2 billion people in the developing world have no access to electricity. For these people, PV is probably the most economical power source today. It is anticipated that within the next 5 to 10 years, PV will become cost competitive with traditional power sources in countries with extensive electrical infrastructure (like the US and Europe).

30 Rising Oil Prices

31 Future Developments Improved crystallisation processes for high quality, low-cost silicon wafers Advanced silicon solar cell device structures and manufacturing processes Technology transfer of high efficiency solar cell processes from the laboratory to high volume production Reduction of the silicon wafer thickness to reduce the consumption of silicon Stable, high efficiency thin-film cells to reduce semiconductor materials costs Novel organic and polymer solar cells with potentially low manufacturing cost Solar concentrator systems using lenses or mirrors to focus the sunlight onto small-area, high-efficiency solar cells R&D is focused on increasing conversion efficiency and reducing cell manufacturing cost, to reduce electricity generation cost.
