Solar Maintenance Process

The steps to keep your system operating in peak condition

Omzen Solar Install Melbourne

Solar Health Check

Detailed report on the current condition of your system, identifying any current or potential  issues.

Specialist advice and a quote for any required repairs or rectification.

Maintenance reports can be imperative if you need to make a warranty claim where the manufacturer asks for evidence of regular maintenance checks to validate a warranty.

So, what needs to be checked?

  • Inspect inverter and record readings
  • Test of installation
  • VOC and ISC test results
  • Insulation resistance and irradiance
  • Check panels for any visual defects, configuration, specifications and earthing of the array
  • Check frames/racking for corrosion and installation integrity
  • Check roof fixings
  • Check integrity of cables, connectors and conduit 
  • Check isolators for water ingress
  • Check junction boxes for water ingress
  • Remove physical debris and other fire hazards
  • Check for roof leaks or any damage to roof
  • Check AC and DC isolator integrity, connections, ratings, brand, correct polarity
  • Check MSB for CB and AC cable size, connections and meter installation

Scheduled Maintenance Plan

The components of your system will have extensive product warranties, often 25 years for your panels and 10 years for your inverter. However this does not ensure the efficiency and production of the system without regular maintenance.

Frequent checkups can help to avoid costly faults and ensure the longevity of your system’s performance.
For each scheduled inspection you will receive a full condition report.
Choose an annual or biannual maintenance schedule.
Maintenance reports can be imperative if you need to make a warranty claim where the manufacturer asks for evidence of regular maintenance checks to validate a warranty.

What can reduce the efficiency of your system over time?

Knowledge is power. Understanding what can affect the longevity of your solar system means you’re better equipped to prevent potential damage before it occurs.

What can damage your inverter?

Solar inverters create their own heat and can be prone to overheating, especially in the hot Australian climate. Choosing an inverter, like a Fronius, with it’s own inbuilt fan for cooling can help to significantly extend the life of your inverter. Also, ensuring your inverter is adequately protected from direct sunlight during the day is essential for maintaining efficient AC power output.

Loose wiring and connections can cause an inverter to arc. An electrical arc is a release of electrical energy which can cause fire or explosion. Regularly checking and tightening connections can help to ensure your inverter is operating safely and efficiently.

What can damage solar panels?

Falling debris or tree branches can shatter a panel causing obvious damage which would prompt panels to be replaced. However strong weather like wind, hail or lightning can cause minor external damage to solar panels, which can then create internal structural issues that are less obvious to identify but can dramatically effect a panel’s overall production.

What are hotspots on solar panels?

Solar panels generate electric current when the sun shines on them. Any imperfections on the solar panel such as significant build up of dirt and leaves, microcracks, or poorly soldered joins can cause an uneven distribution of heat, with hot spots developing. Over time these can cause ‘burn marks’ on the panel and even fire.

What are microcracks on solar panels?

The silicon used in manufacturing solar cells is very thin and microcracks can form over time from external factors such as hail and falling debris, or extreme temperature changes from day to night. Microcracks are often invisible to the human eye. Whilst they are tiny imperfections, they cause the solar cell to stop conducting electricity putting stress on the surrounding cells, increasing the chance of hot pots and decreasing the overall efficiency of the system.

Does rain clean solar panels?

Heavy rain will help to rinse everyday dirt and grime from your solar panels if they are on tilt. However, just like rain doesn’t make your car sparkling clean, rain will not remove dried-on animal droppings, thick dirt or leaves. Cleaning is essential for flat panels as the water will not run off naturally. For any system, cleaning can help to reduce hotspots and microcracks and improve the overall efficiency and lifespan of your system.
