Solar repairs and inverter replacement in Sumner
Health checks, fault finding and inverter replacements for any brand of solar system in Sumner, including ones we did not install.
Repairs & upgrades for Sumner, planned around your home
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 Sumner 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 west takes in leafy riverside suburbs like Indooroopilly, Kenmore and Chapel Hill, the Centenary suburbs, and hillier, tree-lined streets around The Gap, Ashgrove and Ferny Grove where shading needs careful planning. From Sumner to nearby Jamboree Heights and Middle Park, we quote every job in person so the price you sign is the price you pay.

Getting to know Sumner
Sumner Road, along the northern boundary, gave the suburb its name, and the road itself is linked to a lawyer who spent weekends at his property at its end. The land was once Wolston Estate farmland, auctioned in 1901, and became part of the Centenary Project in 1959. The name was made official in 1969, and the memorial gardens opened in 2001.

Repairs & upgrades in Sumner: 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 Sumner 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 Sumner 4074 and nearby suburbs?
Yes. Sumner is part of our Brisbane Westside service area in the Brisbane City Council area, and we regularly work in Jamboree Heights, Middle Park, Darra, Mount Ommaney. Call 0449 942 735 or request a quote online and we will reply within 24 hours.
