When to Call a Professional: Solar Panel Repairs You Shouldn’t DIY

Solar panels are remarkably durable systems designed to withstand decades of weather exposure while generating clean energy for your home. However, like any technology, they occasionally require repairs and maintenance. While homeowners can handle some basic cleaning and visual inspections, certain repairs should never be attempted without the expertise of a professional.

Understanding when to step back and call in the experts isn’t just about getting the job done right—it’s about protecting your safety, preserving your investment, and ensuring your solar panel system continues operating at peak performance. Here are the key situations where professional intervention is essential.

Electrical Issues: High-Voltage Hazards That Require Expert Handling

Electrical issues within your solar system require specialised knowledge of DC electrical systems, safety protocols, and proper shutdown procedures.

Warning signs that require immediate professional attention include:

• Faulty wiring connections showing signs of corrosion or burning

• Damaged junction boxes with visible cracks or water intrusion

• Issues with electrical conduits or protective covering

• Reduced energy production without obvious cause

• Error codes appearing on your monitoring system

• Visible burn marks around electrical components

• Unusual sounds like crackling or buzzing from electrical components

Professional solar technicians possess the specialised tools and training necessary to safely isolate electrical systems, test voltage levels, and make repairs without compromising safety.

Structural Roof Damage: When Panel Problems Affect Your Home’s Integrity

Solar panels are integrated into your roof structure through mounting systems that must maintain the integrity of your home’s weather barrier. When these mounting points fail, leak, or become damaged, the problem extends far beyond your solar system to potentially compromise your entire roof structure.

Issues like loose mounting hardware, damaged flashing, or compromised roof penetrations require expertise in both solar technology and roofing systems. Water intrusion from failed mounting points can lead to expensive structural damage, mould growth, and interior damage that far exceeds the cost of professional repairs.

Additionally, walking on roofs to inspect or repair solar installations presents significant fall hazards.

Inverter Malfunctions: Complex Electronic Repairs Beyond Basic Troubleshooting

Inverters are sophisticated electronic devices that convert the DC electricity generated by your solar panels into AC electricity, which is compatible with your home’s electrical system. When inverters malfunction, they require specialised diagnostic equipment and technical expertise to be repaired or replaced correctly.

Modern inverters contain complex circuitry, software systems, and safety mechanisms that can only be serviced by trained technicians. Attempting to open or repair an inverter can expose you to dangerous electrical components and will almost certainly void your warranty coverage.

Inverter problems often require firmware updates, component replacement, or complete unit replacement—all of which must be performed according to manufacturer specifications and local electrical codes. Professional technicians have access to diagnostic tools, replacement parts, and technical support that aren’t available to consumers.

Warranty-Voiding Repairs: Protecting Your Investment with Professional Service

Solar panel systems typically come with comprehensive warranties that cover both the equipment and the installation work. However, these warranties often become void if unauthorised repairs or modifications are performed on the system. DIY repairs can eliminate your warranty protection when you need it most.

Manufacturer warranties typically require that all repairs be performed by certified technicians using approved replacement parts and procedures. Even seemingly minor repairs, if performed incorrectly or with non-approved components, can void warranty coverage for the entire system.

Professional solar companies maintain certifications with equipment manufacturers and are familiar with warranty requirements. They can perform repairs that maintain your warranty coverage while ensuring the work is completed to the manufacturer’s specifications.

Safety-Critical Components: Grounding, Wiring, and Fire Prevention Systems

Solar installations include multiple safety systems designed to prevent fires, electrical hazards, and equipment damage. These safety-critical components must work together seamlessly and require professional expertise to be adequately repaired or modified.

Key safety components that require professional service include:

• Grounding systems that protect against electrical shock and equipment damage

• Rapid shutdown devices ensuring panels can be quickly de-energised during emergencies

• Arc fault circuit interrupters that prevent electrical arcs from starting fires

• Emergency disconnect switches for immediate system isolation

• Ground fault circuit interrupters protecting against electrical faults

• Surge protection devices guarding against voltage spikes

• Proper bonding connections between all metallic components

Modifications or repairs to safety systems must comply with current electrical codes and manufacturer specifications.
