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.

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

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

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

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

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

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.
