Highlight of major issues in 2012
41
Total 4% energy loss in 2012 because of various field
failures
Construction related failures• Use of under-speced parts• Poor workmanshipGrid related failures• Grid fluctuations• Planned and un-planned grid shut downParts/Material failures• Modules and inverters related
Supplier quality issues
43
Potential induced degradation (PID effect) in modules (silent killers)
• >50% reduction in module output• Conditions required for PID
• - ve floating• Crystalline modules• High voltage of strings (> 600 V)• Humidity• Site temperature• Cable faults
Excessive h/w and firmware related failures in inverters
• Inability to absorb grid fluctuations led to IGBT failures• h/w and firmware level modifications required to reduce failure
rates
