Scope of Solar Panel Services and Procedure
The scope of O & M is for trouble free operation of the power plant to ensure that maximum solar energy is fed to the grid. Following activities are envisaged as part of O & M:
- Trouble free operation of the Power Plant.
- Ensure that the Power Generated is pumped to Grid without any problem.
- Monitor the Performance of the Power Plant by data logging.
- Monthly report preparation & reporting to Customer on performance of Power Plant.
- Maintenance of Module – Periodic cleaning of 1 MW Solar PV Modules
- Scheduled maintenance of Inverter, LT, and HT & Transformer.
- Attend the emergency break down of the components.
- Frequent testing of plant equipment by ‘Walk Down’ checks the internal condition of equipment such as module performance, inverter efficiency test, monitoring system testing etc.
- Careful logging of operation data and periodically processing it to determine abnormal or slowly deteriorating conditions.
- Careful control and supervision of operating conditions. (Wide and rapid variations in voltage and frequency conditions do contribute to increased maintenance).
- Regulate routine maintenance work such as housekeeping of plant area, keeping equipment clean, cleaning of modules, proper maintenance of inverters etc.
- Spare parts and inventory maintenance.
- Proper codification of all spares and consumables.
- Spare parts indenting.
- Indenting and maintaining minimum level of critical mandatory and recommended spares.
