North Carolina ranks among the top U.S. states for solar energy, with homeowners from Charlotte to Raleigh enjoying cleaner power and lower energy bills. However, NC’s unique blend of hot summers, hurricanes, pine pollen, and high humidity can challenge the longevity of your solar panel system.

If you want to protect your investment and maximize savings, watch for these top 5 signs your solar panels might need repair in North Carolina.

1. Unexpected Decline in Energy Production

During North Carolina's long, sunny seasons, your solar system should produce consistent output. If your energy monitoring app or utility bill shows lower-than-normal production, that's a red flag.

Common Causes in NC:

Pollen buildup in spring (especially pine pollen)
Partial shading from tree growth
Inverter or wiring malfunction
Panel degradation from UV exposure

What to Do: Compare your current energy production to previous years. Contact a local North Carolina solar technician to assess the system and determine if there is a noticeable drop.

2. Storm or Hurricane Damage

North Carolina's storm season can be harsh, from tropical storms to full-blown hurricanes. High winds, hail, and flying debris can damage solar panels or misalign mounting hardware.

Signs of Storm Damage:

Visible cracks or scratches on panel surfaces
Loose panels or racking
Disconnected wiring or junction boxes
Water intrusion near panel edges

What to Do: After any major storm, schedule a post-weather inspection with a qualified solar repair technician. Early detection prevents larger (and costlier) repairs later.

3. Inverter or Electrical Warning Alerts

If your solar inverter blinks red or yellow, displays error codes, or shuts off, it may indicate an electrical failure.

Common in NC Homes:

High humidity causes corrosion
Improper grounding or surging during lightning storms
Inverter age (many fail after 7–10 years)

What to Do: Leave inverter diagnostics to the pros. A solar repair technician can safely test the components and replace or repair parts under warranty.

4. High Power Bills During Sunny Months

Your solar system is supposed to reduce your utility bill, especially from April through October when the sun is strongest in North Carolina. If your bills increase without a corresponding change in usage, your panels may not be performing as expected.

Possible Causes:

Soiled panels (pollen, dust, or sap buildup)
Shading from summer tree growth
Loose wiring
Underperforming microinverters or strings

What to Do: Get a system performance check. A technician can clean your panels, test all outputs, and identify weak or damaged components.

5. Pest or Animal Damage

Squirrels, birds, and even snakes in North Carolina often take refuge under warm solar panels, particularly during the cooler months. Unfortunately, they often chew wires or damage mounting hardware.

Look for These Signs:

Exposed or frayed wiring
Animal droppings or nests under the array
Sudden drops in performance
Breakers tripping without cause

What to Do: We recommend Critter Guard installation in North Carolina to prevent recurring damage. It's a small investment that saves major repair costs.
