  1. Solar Project Performance Assessment Firstgreen Webinar Series : 29th April 2014

  2. About Firstgreen Consulting

  3. Speakers • Dr. Sanjay Vashishtha • CEO, Firstgreen Consulting • Mr. Basant Jain • CEO Mahindra EPC

  4. Key Topics

  5. Solar Plant Performance Assessment

  6. Performance of Solar Plants in India The Performance of Solar Plants has been improving over last few years

  7. Requirement of SPV plant Assessment Plant performance is dependent on BoS and System Sizing It is also dependent on the better O&M practices

  8. Plant Data Monitoring Strategies V,I V,I V,I, kWh V,I kWh At the PV panels the solar radiation is being recorded At string level measurement of current & Voltages are monitored At inverter level V,I are measured at the input as well as at output level. The kWh is also measured The energy injected to the grid is measured at the ABT meter

  9. Performance Assessment at String Level

  10. String Performance can be affected due to Five Key Factors The Underperforming string

  11. Shadow Losses Shadow losses can significantly reduce your plant performance

  12. Inter-row spacing and Shading • Inter row shading needs to be optimised. This can cause significant losses in your plant.

  13. Monitoring the String Voltage and Currents IV Curve of a partially shaded string

  14. Benchmarking of String Performance • Array string performance to each other. • String performance to a Standard Panel. • String performance to specific Solar Radiation level. • Panel to Panel performance within a string or to standard.

  15. Inverter Performance Analysis This inverter is performing poorest This inverter is performing best

  16. Assessment of Plant losses

  17. Monitoring instruments Thermography Megger Tong tester Power meter IV Tracer Pyranometer

  18. Use of Thermography in Solar Plant Performance Assessment

  19. Step by Step Approach to conduct Plant Performance Assessment

  20. Five Step process for Plant Performance Assessment Monitor the results for continuous improvement? Implement the options Priorities the feasible options Feasibility analysis Where are the bottlenecks? Identification of Options Validate the available Information Site Assessment Analyze the data in advance : Planning and organization
