Solar repairs and inverter replacement in Willawong
Health checks, fault finding and inverter replacements for any brand of solar system in Willawong, including ones we did not install.
Why Willawong homes choose RS Energy for repairs & upgrades
Inverters are the hardest working part of a solar system and most last 10 to 15 years. When one fails, your panels keep sitting in the sun but you get nothing from them. Many Willawong homes also have systems that were installed by companies no longer around.
We test the array, inverter, isolators and wiring, then give you a clear written report. If replacement makes more sense, we will quote a like-for-like inverter or a hybrid inverter that is ready for a battery.
Brisbane's southside covers older post-war suburbs like Annerley, Moorooka and Holland Park, the busy family areas around Sunnybank, Mansfield and Carindale, and newer pockets at Pallara and Forest Lake. Our repairs & upgrades work in Willawong also covers neighbouring Pallara, Doolandella and Durack, all within about 2km.

Willawong: a local snapshot
The Queensland Place Names Board created and named Willawong in 1970, using an Aboriginal word for the junction of two creeks. Four years later most of the suburb went under in the 1974 Brisbane flood. Residents fought sand mining proposals in 1983, and a toxic waste dump that once operated here was shut in 1998.

Repairs & upgrades in Willawong: questions
Still unsure? Talk to us directly. You will speak with the people who do the work.
Call 0449 942 735How do I know if my solar system is faulty?
Common signs are an inverter showing a red light or error code, a blank screen during the day, a power bill that jumps without a change in usage, or monitoring that shows zero output on a sunny day.
Do you fix systems you did not install?
Yes. A lot of our repair work in Willawong is on systems from companies that have since closed. We work on all mainstream brands.
Should I repair or replace my inverter?
If the inverter is under warranty, we will help you claim it. If it is over 10 years old and out of warranty, replacing it is usually better value than repairing, and it is a good moment to consider a battery-ready hybrid.
How often should solar panels be checked?
Every two to three years is a good rule, or sooner near the coast where salt air is harder on fixings and isolators.
Do you service Willawong 4110 and nearby suburbs?
Yes. Willawong is part of our Brisbane Southside service area in the Brisbane City Council area, and we regularly work in Pallara, Doolandella, Durack, Inala. Call 0449 942 735 or request a quote online and we will reply within 24 hours.
