Solar panel system maintenance

Maintaining your solar panel system is essential to ensure your solar panels are operating safely and efficiently. By having our qualified and experienced solar electricians perform routine maintenance inspections, your solar panels will always be performing their best!

Of course, you take your car for its annual maintenance inspection, right? So, considering your solar panels are working all day, every day, why wouldn’t you be having your solar system inspected?! To ensure you are getting the best performance from your solar panels, they should be inspected annually.

Book a solar system inspection with one of our experienced, CEC qualified electricians today.

Solar panel system inspection

Solar panels are exposed to the harsh Australian elements and animals that cause damage or cover the panels in droppings. These factors can affect the efficiency of your system’s performance and our friendly team at Powerix can ensure it is in optimal working order and condition.

Our inspections consist of a review of the following:

• Solar inverter
• Solar panels
• Solar isolator
• Wiring
• Mounting array frame
• System performance

Solar system testing

We perform rigorous testing of your solar system, which includes the following:

• Measure the position of a single ground fault in a PV string (Riso < 3 MΩ)
• Measure the position of a single disconnect in PV strings (Rs > ten kΩ)
• PV string impedance curves (health and degradation check)
• PV string series resistance Rs
• PV string open circuit voltage VOC
• PV string short circuit current Isc
• PV system isolation resistance Riso
• PV module voltage
• PV module bypass diode check (open or short circuit)
• PV module shunting resistance Rsh (module/cell degradation)

Solar panel system efficiency testing

Have your utility bills risen unexpectedly recently? This is likely to be due to the efficiency of your solar system and efficiency testing is often overlooked. The panels are the most important investment of your home energy system, and an efficiency test can make sure they’re producing their maximum output.

Powerix measures the efficiency of solar systems and compares it to panel data sheets (STC).

Power loss of the system can be caused by the following components and so measurements are taken of:

• Inverter's efficiency - both AC and DC side at the same time
• Voltage and current
• Irradiance and module temperature
