Correctve Maintenance
≈
Proactive Maintenance
ý

11. Preventive Maintenance
What is it? - Works defini>on and scheduling plan
Objectives - Minimize downTmes
- Enlarge lifeTme of the equipment
- Minimize Risks (H&S, Security, etc)
- DetecTng faults for claims
When? - In low irradiaTon periods
- According to meteorological condiTons
Needs - Schedule Plan & Trained staff
- Tools and auxiliary machinery
- Management of work orders / Spare Parts
- IT Pla`orm

12. Corrective Maintenance
What is it? - ResoluTon of incidences
Objectives - Minimize downTmes
- Increase Availability & Performance Ra>o
Factors - Incidences Protocols incorporated
- Spare Parts available
- Trained team
- Warranty Manufactures
Needs - Monitoring System
- Tools and auxiliary machinery.
- Management of work orders/Spare Parts
- IT Pla`orm

13. Proactive maintenance
What is? - Analysis for detecTng underperformances
Objectives - Avoid hidden defaults & losses
- Enlarge lifeTme of the equipment
- Minimizes risks
- ProducTon increase
How? - Due Diligences
- Analysis of electrical parameters
- Trends evaluaTons & Comparisons
Needs - Specialized Tools & IT management
- IV, Analyzer PV, Thermographic Camera…
- Specialized Team

14. Factors Impacting Production Losses
What really contributes to the loss of
generation and how much?

15. Design & Construction O&M Environmental Factors
• Near shadings: irradiance loss
• IAM factor
• Shadings: Electrical loss acc. to string
• LID-Light Induced DegradaTon
• Module array mismatch loss
• Ohmnic wiring loss
• Inverter loss during operaTon
(efficiency)
• Inverter loss over nominal inv. power
• Inverter loss due to power threshold
• Inverter loss over nominal inv. voltage
• Inverter loss due to voltage threshold
• AC ohmnic loss
• External transfo loss
• Soiling loss factor
• System
unavailability
• Near shadings: irradiance loss
• IAM factor
• PV loss due to irradiance level
• PV loss due to temperature
• Shadings: Electrical loss acc. to
string
• LID-Light Induced DegradaTon
