15 Essentials for Solar PV Maintenance

Here’s a list of 15 essential items that can be included in every annual service and maintenance schedule conducted by Solar Now for your solar PV systems; these items help to ensure optimal performance and longevity for your investment:

1. Visual Inspection of Solar Panels

Check for cracks, scratches, discoloration, or delamination on the surface of the panels.

2. Cleaning of Solar Panels

Remove dirt, dust, bird droppings, and debris that could reduce energy output.

3. Inspection of Mounting Structures

Check for corrosion, loose bolts, and proper alignment of the racking system.

4. Verification of Electrical Connections

Inspect all connections (e.g., DC cables, connectors, and junction boxes) for corrosion, looseness, or damage.

5. Performance Testing

Compare current system output (in kWh) to expected performance benchmarks based on irradiance and historical data.

6. Inverter Inspection

Inspect the inverter for proper operation, error codes, or signs of overheating and clean the cooling fans if necessary.

7. Inspection of Wiring and Cabling

Look for signs of wear, exposed wires, rodent damage, or UV degradation of insulation.

8. Thermal Imaging Survey

Conduct a thermal scan to identify hotspots, underperforming modules, or wiring issues.

9. Monitoring System Check

Test the data acquisition system (if present) to ensure monitoring hardware/software is functioning properly.

10. Junction Box and Combiner Box Inspection

Check for moisture ingress, loose connections, and proper fusing inside the boxes.

11. Earth/Grounding System Check

Verify that grounding connections are intact and meet safety standards to avoid electrical hazards.

12. Battery System Maintenance (If Applicable)

Check state of charge (SOC), electrolyte levels, and terminal connections for energy storage systems.

13. Surge Protection Device (SPD) Inspection

Inspect surge protectors for wear and ensure they are properly rated and functional.

14. System Safety Checks

Test safety features like disconnect switches, rapid shutdown functionality, and overcurrent protection devices.

15. Maintenance of Documentation

Update system documentation, including maintenance logs, warranty records, and performance reports.

Further Information on Maintenance

Frequency: While these are recommended annual checks, some items (for example, cleaning and visual inspections) may need to be performed more frequently based on the environment (e.g., dusty or coastal areas).
Professional Assistance: Inverters, electrical connections, and other technical components should be inspected by qualified technicians.
Detailed Reporting: Solar Now can also provide more detailed reporting to system owners, highlighting findings, actions taken, and any recommendations.

Solar Now can work with you to create a detailed maintenance schedule and checklist for your unique needs and objectives.
