Economics of Solar PV Power

  1. 1. ECONOMICS OF SOLAR PHOTO- VOLTAIC POWER TRAINING ON SOLAR PV SYSTEM Sudhanwa Sahoo Manager, Marketing & Business Development Email:sudhanwa.sahoo@gmail.com Agni Power And Electronics Pvt. Ltd. 114, Raj Danga Gold Park, Kolkata-700107 TRAINING ON SOLAR PV SYSTEM JULY-2015
  2. 2. INTRODUCTION • Sunshine is free, But Capturing the sun’s rays to generate electricity is a Capital-Intensive undertaking. • High Up-Front / Capital Cost & Low Operating• High Up-Front / Capital Cost & Low Operating Cost • Project Development Time is Minimum as compared to Other Power.
  3. 3. SOLAR PV POTENTIAL
  4. 4. TYPICAL SOLAR PV SYSTEM •SOLAR PV MODULE •CHARGE CONTROLLER CUM INVERTER (PCU)CUM INVERTER (PCU) •BATTERY •OTHERS
  5. 5. Solar PV Technologies Efficiency (%) Price (Rs./Wp) Remarks Mono Crystalline Silicon 15-18 45-50 Effi: High Cost: High Reliability: High Risk: Low SOLAR PV TECHNOLOGIES Risk: Low Poly Crystalline Silicon 13-16 38-40 Effi: Medium Cost: Medium Reliability: High Risk: Low Thin Film 6-9 30-35 Effi: Low Cost: Low Reliability: Low Risk: High (More Space Req)
  6. 6. COST OF TYPICAL 100kWp Grid-Tied SOLAR PV POWER PLANT (Rs.) Particulars Figures (in Lakhs) 1. SOLAR PV Module: 50 2. PCU/Inverter: 12 3. Module Mounting Structure: 7 4. Cables: 54. Cables: 5 5. Junction Box: 2 6. I&C and Others: 4 7. Total: 80 1 2 3 4 5 6
  7. 7. COST OF TYPICAL 100kWp HYBRID SOLAR PV POWER PLANT (Rs.) Particulars Figures (in Lakhs) 1. SOLAR PV Module: 50 2. PCU/Inverter: 30 3. Battery: (40kW for 4-6 Hrs) 30 4. Module Mounting Structure: 54. Module Mounting Structure: 5 5. Cables: 5 6. Junction Box: 2 7. I&C and Others: 8 8. Total: 130 1 2 3 4 5 6 7
  8. 8. INPUT DATA FOR ECONOMIC ANALYSIS OF SOLAR PV POWER PLANT TECHNICAL INPUTS UNIT COMMERCIAL INPUTS UNIT CAPACITY OF SOLAR POWER PLANT kWp CAPITAL COST OF SOLAR POWER PLANT Rs. YEARLY SOLAR DAYS DAYS OPERATING COST OF SOLAR Rs.YEARLY SOLAR DAYS AVAILABLE DAYS OPERATING COST OF SOLAR POWER PLANT Rs. UNIT GENERATION PER kWp INSTALLED CAPACITY kWh/kWp OTHER FINANCIAL BENEFITS (SUBSIDY, DEPRICIATION ETC.) Rs. TOTAL YEARLY GENERATION OF SOLAR POWER PLANT kWh PRICE OF ELECTRICITY (GRID/DIESEL) Rs.
  9. 9. CONCEPT OF ECONOMIC ANALYSIS • ALL DATA TO BE CONVERTED TO FINANCIAL FIGURES. • COMPARISON SHOULD BE LOGICAL & PRACTICAL. • COMPARISON BETWEEN CASH OUTFLOW &• COMPARISON BETWEEN CASH OUTFLOW & CASH INFLOW (EXPENSES vs REVENUE) • YEARLY CASH INFLOW SHOULD OUT NUMBER ONE TIME CASH OUT FLOW (PAY BACK). • INCORPORATE TIME VALUE OF MONEY (DISCOUNTING METHOD)
  10. 10. CONTINUED… BENEFITS OF • GRID TIED SYSTEM SHALL BE COMPARED TO GRID POWER. • HYBRID SYSTEM SHALL BE COMPARED TO• HYBRID SYSTEM SHALL BE COMPARED TO DG/OTHER BACK UP POWER SOURCE. • ESCALATION COST IN ELECTRICITY/FUEL & PLANT ENERGY DEGRADATION SHOULD BE ACCOUNTED.
  11. 11. Economic Analysis of 100kWp Grid Tied Solar PV Power Plant
  12. 12. CONCLUSION • Current Average Pay Back of solar plant is on 5th to 6th Year. • Further scope of improvement in pay back with decrease in cost and improvement of technologies.technologies. • Larger Power Plants are with more economies of scale. • Scope for Grid Parity with Other Power Sources in near future with favorable policies.
  13. 13. Some facts About Solar Power Purchase & Trading • PPA: Power Purchase Agreement (Private/Public) • RPO: Renewable Purchase Obligation • REC: Renewable Energy Certificates (1REC=1MWh)(1REC=1MWh) • Trading at Indian Energy Exchange (www.iexindia.com). • NTPC Vidyut Vyapar Nigam Ltd.
  14. 14. NET-METERING • Concept: Recording the net energy between export of generated energy and import of energy from distribution licensee for a given period of time. • Grid Export Meter and Solar Import Meter.• Grid Export Meter and Solar Import Meter. • Other safety and quality standards as prescribed in the Electricity Rules, 2005. • Energy Export Revenue Accounting (As per State Policy)
  15. 15. Solar PV Power Market Scenario • Solar Project are Capital Intensive (Govt. Investment) • Subsidy and/or other Financial Benefits are desirable. • Favorable Policy to boost solar PV demand. (Net- Metering, RPO & REC)Metering, RPO & REC) • Innovative Product/Process to tap newer markets. • Major Thrust on R&D to improve Efficiency of solar PV system. • Low cost finance for large size solar Project.
