Do You Repair Solar Systems Even If You Didn’t Install Them?

Yes, MPV Solar’s Local Sydney Team Can Help, No Matter Who Installed Your System.

When your solar system isn’t working properly, it doesn’t matter who installed it,  what matters is getting it fixed fast. At MPV Solar, we’re proud to help Sydney homeowners with solar system repairs, servicing, and upgrades, even if your original installation was done by another company.

Our Clean Energy Council accredited electricians have been repairing, upgrading, and maintaining solar systems across Sydney since 1992, giving thousands of families peace of mind and reliable solar savings.

Over the years, we’ve seen it all: faulty inverters, damaged panels, wiring issues, and outdated systems that other installers no longer support.
Whether your system was installed five years ago or fifteen, our in-house team can:

• Diagnose inverter and panel faults
• Replace failed components or wiring
• Reconfigure underperforming systems
• Remove and reinstall systems for roof repairs
• Upgrade outdated solar technology for better performance

We’re familiar with all major solar brands including Fronius, Sungrow, Enphase, SolarEdge, Canadian Solar, Jinko, Q Cells, Trina, Sigenergy, LG and more.

Unlike many companies that rely on subcontractors, MPV Solar handles every job in-house. That means you’ll deal directly with our qualified electricians — not a third party.

• Family-owned and operated since 1992
• Local Sydney team,  fast response and genuine aftercare
• CEC-accredited designers and installers
• Repairs, maintenance, and upgrades for all system types
• Honest advice: we’ll tell you whether repair or replacement makes more sense

Our goal is simple: get your solar system running safely and efficiently again, so you can keep saving on your power bills.

If you didn’t install with MPV originally, don’t worry,  we’re used to stepping in to fix systems where the original company has closed down, moved on, or doesn’t offer aftercare.

Common issues we repair include:

• Inverter error messages or shutdowns
• Poor energy production or shading problems
• Faulty isolators or cabling
• Damaged panels or roof mounts
• System not showing on monitoring apps
• Storm or water damage

If your system is more than five years old, it might be worth upgrading your inverter, panels, or adding battery storage.
We can assess your existing setup and provide tailored recommendations to boost performance, efficiency, and future savings — all while making use of current NSW solar rebates and feed-in tariffs.

Even if MPV Solar didn’t install your system, we can still help you get the most out of it.
From quick fault repairs to full system overhauls, our Sydney-based team provides trusted, transparent service every step of the way.
