Solar panels are built to last for decades — but like any home system, they can develop issues over time. Texas weather, debris, and everyday wear can impact performance, efficiency, and even safety.
The good news? Early detection can prevent small issues from turning into expensive repairs. Knowing the warning signs that your solar panels need repair helps keep your system producing clean, reliable energy for years to come.
Here are the 10 most common signs it’s time to call a professional for solar panel repair.
1. Drop in Energy Production
If your solar panels aren’t generating as much power as they used to — even during sunny days — that’s one of the first signs something’s wrong. A sudden or gradual production drop can indicate shading, electrical faults, or internal damage.
2. Inconsistent or Inaccurate Monitoring Readings
Your monitoring app is your system’s report card. If readings are inconsistent, stop updating, or show sudden dips, your inverter or wiring may need inspection. Accurate monitoring is key to identifying hidden issues before they worsen.
3. Visible Cracks or Damage
Cracked glass, bent frames, or chipped corners mean your panels have likely sustained weather damage. Even small cracks can lead to moisture intrusion and decreased performance, so they should be repaired as soon as possible.
4. Corrosion or Burn Marks
Any sign of rust or dark burn marks around wiring, junction boxes, or connectors suggests overheating or electrical damage. These issues can affect both performance and safety — and should always be addressed by a licensed solar technician.
5. Discolored or Cloudy Panels
If your panels look hazy or discolored, buildup or internal moisture might be blocking sunlight. Cleaning can help, but if the issue persists, it could point to deeper damage requiring professional repair.
6. Unusual Noises or Electrical Smells
Solar systems should run silently. If you notice humming, buzzing, or electrical odors near your inverter or panels, stop using the system and contact a technician immediately. These could indicate wiring issues or component failure.
7. Loose or Damaged Wiring
Weather, rodents, or poor installation can cause wiring to loosen or fray. Damaged wires interrupt power flow and can pose electrical hazards. A professional inspection ensures all connections are secure and functioning safely.
8. Frequent Inverter Errors
Your inverter is the brain of your solar system. If it frequently displays error codes or shuts down unexpectedly, your system may need recalibration or inverter repair. This is one of the most common repair calls solar companies receive.
9. Roof Leaks Near Mounting Points
If you see leaks or water stains near where your panels are mounted, the flashing or sealant may be compromised. Prompt repairs prevent roof damage and keep your solar mounts secure and watertight.
10. Increased Electric Bills
If your energy bills are suddenly higher, even though your usage hasn’t changed, your solar system might not be working efficiently. Professional diagnostics can pinpoint the cause — whether it’s wiring, inverter performance, or panel degradation.
Common Causes of Solar Panel Damage
- Severe storms or hail
- Debris impact
- Aging equipment
- Improper installation
- Electrical component failure
Regardless of the cause, quick repairs restore performance and protect your system from long-term damage.
Why You Shouldn’t Delay Solar Repairs
Ignoring solar issues doesn’t just lower efficiency — it can lead to permanent damage. Electrical problems can spread to other components, and water intrusion can harm both your roof and panels.
Prompt repairs not only prevent costly replacements but also protect your warranties and ensure your system continues generating reliable energy.
