Delaware, although one of the smaller states, is making a significant impact with clean energy. Thanks to generous net metering and solar incentives, more homeowners across Wilmington, Newark, and Dover are investing in solar. However, just like any home system, your solar panels require occasional maintenance and repairs, especially in Delaware’s varied coastal climate, which includes high humidity and frequent storms.

Here are the top 5 signs that your solar panels might need repair in Delaware, along with steps to keep your system running at peak performance.

1. Unexpected Drop in Solar Output

Your solar panels should produce a steady stream of electricity, especially during sunny spring and summer months in Delaware. If your solar monitoring app shows a sudden drop in production without a major change in weather, it could be a sign of a malfunction.

Common Causes in Delaware:

High humidity can corrode wiring or connectors
Inverter failure
Shading from fast-growing trees
Panel degradation

What to Do: Compare your current output with that of the same month last year. If you notice a sharp decline, call a Delaware-based solar repair expert for a system inspection.

2. Visible Weather or Storm Damage

Delaware's location near the Atlantic makes it prone to intense thunderstorms, heavy rainfall, and high winds during hurricane season. These conditions can lead to panel damage that isn't always obvious at first glance.

Watch for:

Cracked glass on panels
Panels knocked out of alignment
Debris lodged beneath racking systems
Bent frames or exposed cabling

Why It Matters: Even minor storm damage can lead to performance issues or electrical risks if not repaired promptly.

What to Do: After a storm, schedule a professional visual inspection, even if your system appears to be working properly. A local technician can spot hidden issues before they worsen.

3. Inverter Warning Lights or Alerts

Your inverter is responsible for converting solar power into usable electricity for your home. If it displays a red or yellow light, error codes, or stops working altogether, there is an issue.

Potential Causes in Delaware:

Salt-laden air is causing corrosion in coastal areas
Overvoltage from lightning strikes
Humidity damage to electrical boards

What to Do: Don't try to reset it yourself. Some inverter issues can signal deeper electrical problems. Instead, contact a certified solar technician for an expert evaluation.

4. High Utility Bills Without Increased Usage

If you're suddenly paying more on your electric bill, even though you haven't changed your usage habits, it's likely that your system isn't producing enough electricity.

Common Explanations in DE Homes:

Soiling or pollen buildup on panels
Shading from nearby trees
Microinverter failure
System wiring problems

What to Do: Compare your recent bills with those from past months and review your system's monitoring dashboard. If there's a mismatch, book a full solar performance check with a Delaware solar specialist.

5. Rodent or Critter Damage

Delaware has its share of squirrels, raccoons, birds, and even opossums. These critters often nest under rooftop panels and chew through wires, leading to serious damage and safety hazards.

Signs You Might Have Animal Damage:

Loose or exposed wires
Burn marks or short circuits
Debris or nests under panels
Sudden inverter errors

What to Do: Our team offers critter guard installation in Delaware to help prevent recurring damage and restore your system's safety and efficiency.

Why Timely Solar Repair Is Crucial in Delaware

Delaware's changing seasons and coastal exposure mean your solar system faces unique challenges. Without proper maintenance, you risk:

Lower energy savings
Voided warranties
Shortened system lifespan
Expensive emergency repairs

Routine checkups and quick repairs help ensure your investment continues to pay off year after year.
