10. Importance of solar asset management
Maintenance is very critical for solar assets.  System breakdown and under-performing asset directly impact the revenue and that revenue is irretrievable.“
Keep solar PV industry evergreen for investors.
Factors that can affect :- Data Management, Environmental, technical and human.
Data Management – Reports generation, Time management, Alignment with O&M
Environmental – Pollution, smog/fog, vegetation growth, Grid infrastructure etc.
Technical – System Design, Installation of asset, Module handling at site, Improper termination/connections, Safety hazards, Manufacturing defects, Hotspots, Power factor etc.
Human – Improper handling of Modules, Terminations, Lack of proper training and safety awareness etc.

11. Pre Asset Management Checks
Pre-commissioning quality & safety checks
Power quality analysis post installation – Grid fluctuations, availability, DG synchronisation, load management, Harmonics, active/reactive power, actual power losses analysis
Checking terminations, Thermal imaging
Training to client personnel on O&M and safety aspects

12. Asset Management Online monitoring Data Management and reporting
Alignment with O&M
O&M Scheduling – list of activities and periodicity
Focus on preventive maintenance
Battery maintenance – Hybrid/Off-grid assets
Maintaining TAT
Training manpower to operate, analyse and troubleshoot the Solar PV plants which are different in nature compared to conventional plants.
Spares management and response time
Warranty claim management
Feedback from client

13. O&M – case studies [voltage out of range]
Voltage fluctuation due to undersize electrical infrastructure from client, resulted high voltage from solar and tripping of inverters.
Power factor
Before
After

14. O&M – case studies [power factor reduction]
Case 1: Solar PV OFF & load 100% on grid power
Industry Load
Power = 1000kw
Reactive = 050kvar
Apparent = 1050kva
Power factor = kw/kva= 1000/1050
= 0.95

15. O&M – case studies [power factor reduction] Continue…..
Case 2 : Solar PV ON & Load 80% on solar / 20% on grid
800kWp Solar PV
Industry Load
Power = 200kw
Reactive = 050kvar
Apparent = 250kva
Power factor = kw/kva= 200/250 = 0.80

16. Major performance affecting factor
PV Module Cleaning
Frequency of cleaning, quality of cleaning, Unwanted material keep on modules
Design
Proper shadow analysis and inter row spacing
EAST & WEST module - string configuration in single MPPT inverter
Inverter DC loading
Grid infrastructure
Voltage fluctuation result into derating of solar generation.
To maintain Load side PF, reactive power from inverter will curtail solar generation.
Pre-net metering - curtailment of solar generation to match consumption.
Quality and size cable from client
Spare Management
Availability of spares, quality of spares, proper tools
Data Management, Monitoring and Training
Online monitoring – data analysis and reporting
Training to internal and vendor manpower
