PV Operation &
Preventative Maintenance
Once the solar PV plant has been commissioned, preventative maintenance and cleaning program should starts to help optimizing the solar energy generation (KWh)and to extend the life of the plant and rather more for the safe and secure operation of the plant. Solar Plant that is not well maintained and PV Modules that are not cleaned can experience dramatic reduction in generated energy and high risk of downtime.
Best Practice for Operation & Maintenance
PV Module Cleaning
Soiling by dust and snow has significant impact on the performance of solar system and sharply reduce generated solar energy particularly in locations where sand storms are common. Many factors can impact the selection of means and methods and frequency of PV module cleaning and it varies from one plant to another. Evaluation of manual vs robotic, dry vs wet cleaning, plant size, location and cost of maintenance all should be considered in developing the maintenance program for a plant.
Preventative Maintenance
Preventing problem before it happens is far cheaper than fixing it after discovered. A proper preventive maintenance plan assures optimal performance and detect potential defaults to avoid sudden breakdown and costly repair. Preventative maintenance program scope of work includes performing periodical inspection and testing on both DC and AC sides of the plant including; PV modules, inverters, cables and terminations. Evaluating the overall system safety measures and testing functionality of fire detection and fire prevention is essential part of the preventative maintenance program.
Corrective Maintenance
Corrective Maintenance is a maintenance activity undertaken to overcome the failure or damage found during the preventive maintenance. Corrective maintenance with short response time and consuming reasonable low resources (both labor and materials) is very efficient way to minimize the downtime and maximize the return of investment (ROI)
PV Preventative Maintenance Plan:
- PV module cleaning
- Inspection of mounting structure, DC and AC cabling and cable trays
- Inspection of inverters
- Inspection of Battery Bank(Off grid systems)
- Measurement of system parameters
- Reporting and Recommendations
