Maintenance

Proper maintenance is essential to ensure the optimal operation, efficiency, and longevity of a solar energy system. Over time, panels and components can wear out or get dirty - things like dust, leaves, or debris can lower how much energy the system produces. Preventive maintenance help avoid failures, optimize performance, and maximize the financial return on investment.

Below is an overview of the key maintenance activities for photovoltaic systems:



VISUAL INSPECTION AND GENERAL MAINTENANCE

  • Support structure inspection: Check of the moounting systems to ensure they are stable, intact, and free from signs of damage, corrosion, or structural failure.
  • Photovoltaic panel inspection: Visual inspection of the panels to identify any cracks, delamination, oxidation, or physical damage that could affect performance.

  • Wiring and electrical connection inspection: Check that cables and connectors are in good shape, with no sign of wear, corrosion, or potential electrical issues.



    • PANEL CLEANING

  • Dust and debris removal: Dust, dirt, and debris can reduce the efficiency of photovoltaic panels. Cleaning is carried out using soft brushes or specialized equipment, avoiding harsh chemicals that could damage panels surface.
  • Checking for corrosion: During cleaning, the panels are also checked for any sign of corrosion, which may indicate long-term issues if not addressed.
  • Cleaning of drainage systems: Roof drainage systems or areas around the panels must be cleared to prevent water accumulation that could harm the installation.



    • PERFORMANCE CHECKS AND MONITORING

  • Energy production monitoring: Periodic checks of the system's energy production, compairing it with historical data and prejected output. A significant drop in performance may signal a malfunction or reduced panel efficiency.
  • Inverter check: The inverter is a key component, converting the DC energy generated by the panels into usable AC energy. Maintenance involves checking the inverter for faults, errors, or failure.
  • Remote monitoring system check: For systems equipped with remote monitoring, it's essential to verify data accuracy and ensure the system is functioning correctly to detect any anomalies in production or performance.



    • BATTERY CHECK (SYSTEMS WITH ENERGY STORAGE)

  • Battery condition check: If the photovoltaic system includes an energy storage solution, maintenance involves checking the status of the batteries - capacity, wear level, temperature, and connections - to ensure they are effectively storing and delivering power.
  • Check of management storage system: Managing stored energy properly helps avoid overcharging or deep draining, which can reduce battery life and affect system perfomance.



    • INSPECTION OF PROTECTIVE DEVICES

  • Fuse and circuit breaker check: Protection devices such as fuses and circuit breakers must be inspected regularly to ensure they operate correctly during an overload or short circuit.
  • Grounding is crucial for safety. It should be checked often to ensure everything is functioning correctly and safely.



    • SHADING INSPECTION

  • Looking for new obstacles: The area around the photovoltaic system must be monitored fot the appearance of new obstacles such as trees, buildings, or other structures that could cast shadows on the panels. Shading can significantly reduce the system's efficiency, so it's important to remove obstructions or repositions the panels if needed.



    • REPLACEMENT OF DAMAGED COMPONENTS

  • Photovoltaic panel replacement: If a panel is too damaged to fix or show manufacturing defects, it must be replaced to prevent efficiency losses.
  • Replacement of electrical components and wiring: In case of failures or wear in electrical connections or inverters, the affected components must be promptly replaced to avoid service interrumptions.
