12. WHY PV SYSTEM MONITORING?
Cause Of Yield Loss During All Phases
Planning phase
Construction phase
Operation phase
An independent quality assurance identifies problems early, increases yield and secures the
investments.
12
13. WHY PV SYSTEM MONITORING?
Cause Of Yield Loss
• Shadow
• Reduced output of the inverter
modules
• Dirt on modules
• Degradation
• Cabling
• String failure solar modules monitoring
• Inverter failure
• Grid failure
13
14. WHY PV SYSTEM MONITORING?
Common Failure Sources
Shadow Dirt
Hotspot Fire
14
15. WHY PV SYSTEM MONITORING?
Yield Loss Due To Shading
Effect of shading on MPP, e.g. chimney
+ even the shadowing of one cell affects your yield
15
16. WHY PV SYSTEM MONITORING?
Yield Loss Due To Incorrect Installation
• Incorrect installation can lead to
failure and yield reduction

18. WHY PV SYSTEM MONITORING?
What Does Yield Loss Mean?
Example: Small PV system with 6 kWp
Inverter defect: - 12.6 %
Yield loss per year: - 306 EUR
+ professional monitoring pays off
18
19. WHY PV SYSTEM MONITORING?
What Does Yield Loss Mean?
Example: Medium PV system with 170 kWp
Shadowing: - 0.6 %
Dirt on modules: - 5.0 %
Module degridation: - 9.8 %
Loss: - 15.4 %
Yield loss per year: - 10,600 EUR
+ professional monitoring pays off
