How to maintain your Solar System

Regular maintenance is essential to ensure the efficiency, performance, and longevity of your solar energy system. By following these maintenance guidelines, you can maximise your investment and contribute to a more sustainable future.

Regular Inspection

Routine inspections help identify potential issues early and ensure your solar system operates efficiently. Check the panels for damage such as cracks or corrosion, and ensure connections are secure. Remove any debris or leaves blocking sunlight. Inspect the mounting structure to confirm it is secure.

Cleaning the Solar Panels

Solar panels can accumulate dust, dirt, bird droppings, and pollen, reducing their efficiency. Clean them regularly with a soft cloth, gentle brush, or a hose with low-pressure spray. Avoid abrasive materials or harsh chemicals to prevent damage.

Monitoring Performance

Use the system's monitoring tools or software to track performance regularly. Monitor for any significant drop in electricity generation, which may indicate issues like a malfunctioning inverter or faulty connections. Prompt detection ensures timely repairs.

Inverter Maintenance

The inverter converts the DC electricity from the panels into AC electricity for use. Ensure it is functioning correctly and free from dust or debris. Follow the manufacturer's maintenance instructions and schedule regular servicing if needed.

Battery Maintenance (if applicable)

If your system includes battery storage, maintain the batteries according to the manufacturer’s guidelines. This includes regular inspection, cleaning, and testing. Ensure secure connections and proper electrolyte levels to maximise lifespan and performance.

Professional Maintenance and Servicing

While some tasks can be done by the system owner, professional servicing is advisable for in-depth inspections, testing, and repairs. Solar technicians can identify and address underlying issues, ensuring the system's safety and efficiency.

Safety Considerations

Always prioritise safety. Switch off the system and disconnect it from the grid before performing any maintenance tasks. For complex issues, contact a qualified solar professional to avoid risks.

Recommended Maintenance Schedule

Monthly:

  • Visual inspection of modules, battery, inverter, and cabling

Quarterly:

  • Clean modules
  • Perform battery maintenance

Annually:

  • Check the mechanical integrity of the array structure and PV modules
  • Inspect all cabling for mechanical issues
  • Verify the output voltage and current of each array string
  • Inspect electrical wiring for loose connections
  • Check the operation of the PV array DC isolator (follow system shutdown procedures)

Every 5 Years:

  • Inspect overall wiring installation and integrity

By adhering to these maintenance practices, you can ensure the long-term performance, efficiency, and reliability of your solar energy system. Regular inspections, cleaning, monitoring, and professional servicing reduce maintenance costs and enhance the benefits of your solar investment.
