In light of the growth and continued maturation of photovoltaic market, safe and proper maintenance of the systems forms an integral part as it maximizes both energy yield and the plant’s life.

NextJoule provides efficient and effective operation & maintenance services that guarantees maximum profitability.

Photovoltaic O&M approaches can be classified into the following categories, depending on cost-benefit tradeoffs and risk factors:

• Scheduled or Preventive Maintenance: This is a planned activity and the expenditure is budgeted in advance. It encompasses identifying existing problems, preventing future problems, and conduct thorough inspection of the plant and photovoltaic components. The inspections should be conducted at regular intervals.
  It includes Panel Cleaning, Water Drainage, Vegetation Management, Wildlife Prevention, and Maintenance of Monitoring and Power Generation System.
• Unscheduled or Corrective Maintenance: It is more of an unplanned activity, which is carried out in response to failures. Here, the possible expenditure is kept in reserve or line-of-credit. It includes On-Site Monitoring, Production Degradation and Loss Issues, and Warranty Enforcement.
• Condition-based maintenance: This type of O&M approach uses real time data to recognize failures and take immediate action on the same.

Preventative Maintenance (PM) includes the following activities:

• Panel Cleaning
• Water Drainage
• Vegetation Management
• Retro-Commissioning (identifies and solves problems that have developed during the course of the PV system’s life.)
• Wildlife Prevention
• Upkeep of Data Acquisition and Monitoring Systems (e.g., electronics, sensors)
• Upkeep of Power Generation System (e.g., Inverter Servicing, BOS Inspection, Tracker Maintenance)
• Site maintenance (e.g., security, road/fence repair, environmental compliance, snow removal, etc.).

Corrective/Reactive Maintenance typically includes:

• On-Site Monitoring
• Non-Critical Reactive Repair (addresses production degradation issues)
• Critical Reactive Repair (high priority, addresses production losses issues)
• Warranty Enforcement

Condition-Based Maintenance (CBM) usually consists in Active Monitoring — Remote and On-Site Options Equipment Replacement (Planned and Unplanned) and Warranty Enforcement (Planned and Unplanned).
