Technical evaluation in cpv systems

  1. 1. Technical evaluation in CPV systems Johana Trujillo, Jose Muñoz and Victor Martinez 4th Concentrated Photovoltaics Conference and Expo. 21 - 22 March 2013
  2. 2. Contents 0 - Introduction to Mott MacDonald 1 - Independent Engineer role 2 – Technical Due Diligence 3 – Standard PV module Bankability 4 – CPV specifics - System Bankability 5 – Conclusions
  3. 3. Who is Mott MacDonald? One of the world’s largest management, engineering and development consultancies We work in over 140 countries From 200 permanent offices On some 16,000 projects Over 14,000 staff Turnover of ~ $1.5bn Employee owned
  4. 4. Multisector
  5. 5. Renewable Energy Expertise • Solar PV &CPV • Solar CSP • Onshore Wind • Offshore Wind • Biomass and Bio-energy • Due diligence (technical, contractual and financial aspects) • Owner’s and lender’s engineering services • Market & Regulatory Support • Feasibility and optimisation studies • Resource assessment and energy yield analysis • Environmental, Planning and Permitting • Technical Specification, Conceptual designs • Project development and management
  6. 6. The Independent Engineer Role • Provide an objective view on a project or a technology for the benefit of investors and/or lenders • Project due diligence and/or technology bankability assessment • Identify any project risk and potential mitigants • Identify areas for improvement – technical • Identify areas for improvement – commercial • Provide support with commissioning and testing • Provide independent reporting
  7. 7. Technical Due Diligence Aim of the TDD: • To understand project risks • To assess technology choice, project design and site layout • To assess plant performance over the debt finance term • To assess permitting and project delivery timetables Provide Comfort and Security to the Lenders Help developers to improve the project Healthy CPV Project -technically and economically-
  8. 8. Technical Due Diligence TDD standard SoW: • Review of the project participants • Review of the proposed technology and project design • Independent energy yield assessments • EPC and O&M contracts review • Project schedule • Review permitting status and environmental issues • Review of the technical inputs to the financial model
  9. 9. • Technical specifications • Certifications • Warranties • Track record • Operational data • Technical specifications • Certifications • Warranties • Track record • Operational data Technical Due Diligence Review of the proposed technology: Available? No Bankability Assessment Yes Review and analysis
  10. 10. Standard PV Module Bankability 1. Factory Quality Management 2. Manufacturing Process 3. Quality control and Testing 1. Factory Quality Management 2. Manufacturing Process 3. Quality control and Testing
  11. 11. Standard PV Module Bankability 1. Factory Quality Management 2. Manufacturing Process 3. Quality control and Testing
  12. 12. 1. Factory Quality Management 2. Manufacturing Process 3. Quality control and Testing Due to CPV specific characteristics both the Bankability Assessment and the Technical Due Diligence processes should be extended to a CPV system level Standard PV Module Bankability
  13. 13. CPV Specifics System Level • Bankability Assessment – Factory Quality Management – CPV module Manufacturing Process – Quality Control and Testing • Technical Due Diligence – Technology Review – Project Design Review – Independent energy yield assessments – EPC and O&M contracts review – Project schedule – Review permitting status and environmental issues – Review of the technical inputs to the financial model
  14. 14. CPV System Bankability • Critical system components’ integration – Cell // Optic elements – Primary // Secondary optics design – Thermal disipation – Module // tracker Achieve a single in-plane surface
  15. 15. CPV System Bankability • High accuracy tracking system – Deformation analysis – CPV module acceptance angle – Open // Close loop control System
  16. 16. CPV System Bankability • MPP tracking System – Inverter MPP tracking system – Reduction of the connection time – Integration MPP tracking // mechanical tracking
  17. 17. CPV System Bankability • Humidity Control System • Long Term Degradation – Lack of long term operational data Rely on tests – Tests under IEC 62108 simulate long term performance – Perform harder tests than the ones defined under IEC standard provides extra comfort (as flat PV manufacturers)
  18. 18. Conclusions • Although CPV is not a new technology is still hard for it to achieve a ‘bankable’ status • Prototype or CPV plants operational data helps its bankability process • Data from different locations provide confidence • The quality standards of the manufacturing facility of the CPV modules will play an important role at this stage of development for CPV. • The individual quality certifications of the CPV system components is very important • Compliance with International standards is a must. • Independent 3rd party analysis provide comfort to lenders • CPV technology has strong development possibilities and could have advantages where innovation solutions are Sought.
