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

CPV System Bankability
• Critical system components’ integration
– Cell // Optic elements
– Primary // Secondary optics design
– Thermal disipation
– Module // tracker � Achieve a single in-plane surface

CPV System Bankability
• High accuracy tracking system
– Deformation analysis
– CPV module acceptance angle
– Open // Close loop control System

CPV System Bankability
• MPP tracking System
– Inverter MPP tracking system
– Reduction of the connection time
– Integration MPP tracking // mechanical tracking

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)

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.
