Solar panels are designed to run quietly and efficiently for years, but that doesn’t mean they’re completely maintenance-free. Over time, exposure to weather, debris, and natural wear can cause performance issues that lower energy output or even shut systems down.
The good news? Most solar system issues are preventable — and fixable — when you know what to look for.
Here are the most common solar problems homeowners experience and how professional service can get your system back to full strength.
1. Reduced Energy Production
If your solar panels suddenly produce less energy than usual, there could be several causes: dirt buildup, partial shading, or damaged components.
A quick cleaning or inspection often solves the issue. However, if production remains low, it’s time for a professional to check the wiring, inverter, and overall system health.
2. Dirty or Obstructed Panels
Dust, pollen, and debris act like a shade over your panels, reducing sunlight absorption. In Texas, seasonal buildup from pollen and dust storms is especially common.
Regular, gentle cleanings keep panels clear and efficiency high — restoring energy production without harsh chemicals or abrasives.
3. Faulty Inverter
Your inverter converts the DC power from panels into AC electricity for your home. When it malfunctions, your system may stop producing power altogether.
Common signs include flashing lights or inconsistent energy data on your monitoring app. Replacing or repairing the inverter restores full system functionality.
4. Wiring or Connection Failures
Loose, corroded, or damaged wiring can interrupt power flow and cause safety risks. These problems often develop over time due to weather exposure.
Licensed solar technicians test every connection and replace damaged wires to restore safe, consistent energy delivery.
5. Micro-Cracks in Panels
Tiny cracks in solar cells can happen from hail, wind stress, or poor installation. While they may not be visible, they can affect efficiency and worsen with time.
Professionals can identify micro-cracks with thermal imaging and replace damaged panels before production loss spreads.
6. Storm or Hail Damage
Severe Texas storms can cause cracked glass, loose mounts, or dislodged panels. Even small hail impacts can affect performance.
A post-storm inspection ensures all panels, wiring, and flashings are intact — preventing leaks or electrical problems down the road.
7. Inaccurate Monitoring Readings
When your monitoring app stops updating or shows incorrect data, it may be due to communication errors between the inverter and monitoring system.
Technicians can recalibrate and reconnect the system so your energy tracking reflects real-time performance again.
8. Roof Leaks Under Panels
Improper installation or degraded flashings can lead to roof leaks that go unnoticed for months. Over time, this can cause water damage and affect panel mounts.
During maintenance, professionals reseal mounts and inspect for roof damage, ensuring the surface stays waterproof and secure.
9. Degrading Mounts and Hardware
Mounting hardware expands and contracts with temperature changes, which can cause loosening over time. Loose mounts risk damaging both your roof and your panels.
Routine inspections tighten mounts, check seals, and keep your system firmly in place year-round.
10. Electrical Overheating or Hot Spots
When certain areas of a panel overheat, it can create energy imbalances and degrade performance.
Thermal inspections detect hot spots early, allowing for adjustments or replacements that prevent long-term damage.
How to Keep Solar Problems from Coming Back
The key to avoiding these issues is regular care and maintenance. Professional inspections catch small problems before they grow, while panel cleaning and diagnostics help maintain top-tier performance all year long.
Homeowners who schedule seasonal maintenance typically see stronger efficiency, lower repair costs, and longer system lifespans — a small investment that delivers major savings over time.
