10 Common Issues That Require a Solar Repair Service
Solar energy systems are built to endure, but unexpected failures happen. When they do, finding a reliable solar repair service quickly can prevent serious energy loss or costly damage. Below are the most common reasons homeowners call solar panel repair companies, and how proactive solar servicing can keep your system running smoothly.
❌ Severe Weather Damage Requiring Solar Repair
Severe storms, hail, heavy snow, and lightning can damage solar panels or exposed electrical components. Cracked glass, water leaks, or dented hardware will reduce power or shut down parts of your system. A professional solar repair service can assess and fix weather-related issues before they lead to long-term problems.
Warranty Tip: Most solar panel product warranties don’t cover weather damage. However, homeowners' insurance often does.
❌ Faulty Installation
Poor workmanship, like loose wiring, bad racking, or improper connections, can cause long-term performance problems. If your system was never producing as expected, solar panel repair companies can inspect the installation and fix underlying issues.
Warranty Tip: Installation flaws may be covered by the original installer, but not by equipment warranties. In fact, improper installation can void your panel warranty altogether.
❌ Solar Inverter Failure & Inverter Repair Service
The inverter is the heart of your solar system—it converts solar power into usable electricity. If it fails, your entire system can shut down. Common causes include overheating, electrical surges, or old age. If your monitoring app shows an error, contact a trusted solar repair service for a diagnosis and inverter repair service.
Warranty Tip: Inverters typically come with warranties ranging from seven to 25 years and vary widely by the type of inverter and the type of solar inverter.
❌ Solar Panel Microcracks & Proactive Solar Servicing
Tiny cracks in solar panels can result from thermal cycling, poor handling, or impact. These microcracks disrupt power flow and may grow over time. Regular solar servicing helps catch them early, before they reduce your energy production.
Warranty Tip: If microcracks are due to a manufacturing defect, they may be covered. Otherwise, you’ll likely need a solar repair service to handle the fix.
❌ Electrical Wiring Issues & Solar Panel Repair
Short circuits, chewed wires, or loose connections can interrupt your solar power supply. Professional solar panel repair companies have the tools and expertise to trace and fix electrical problems quickly and safely.
Warranty Tip: Some product warranties cover electrical faults, but damage from animals or poor installation usually doesn’t.
❌ Animal Damage Under Panels
Rodents, birds, and squirrels sometimes nest under panels or chew wiring, causing unexpected system shutdowns or electrical hazards. Solar servicing can include critter guard installation, wire repairs, and cleanup to protect your investment.
Warranty Tip: Most warranties exclude animal damage, though homeowners' insurance might help cover it.
❌ Power Surges or Overvoltage Needing Solar Repair
Lightning or grid issues can cause power surges that damage your inverter or other system components. After a surge, it’s advisable to schedule solar servicing to inspect and repair any affected parts.
Warranty Tip: Surge-related damage typically isn’t covered by standard warranties unless caused by a defect. Homeowners' insurance may offer coverage.
❌ Component Wear and Tear
Over time, parts like diodes, capacitors, and batteries can degrade. Routine solar servicing helps monitor Over time, parts like diodes and capacitors can degrade. Routine solar servicing helps monitor these components and replace them before failure disrupts your energy production.
Warranty Tip: Wear and tear isn’t usually covered under warranties, which is why regular inspections and maintenance are so important.
❌ Water Intrusion in Solar Panels
If solar panels are poorly sealed or physically damaged, water can get inside, causing corrosion and electrical shorts. A professional solar repair service can reseal your panels and replace any water-damaged parts.
Warranty Tip: If water intrusion is caused by a product defect, it may be covered under warranty.
❌ Manufacturing Defects and Warranty Repair
Sometimes, solar components have factory flaws that cause them to fail early. While many solar panel repair companies can diagnose these problems, the manufacturer typically covers the replacement parts.
Warranty Tip: Product warranties often cover manufacturing defects, but not the labor, which means you’ll likely still need a solar repair service to complete the work.
5 Signs You May Need Solar Panel Repair Solutions
Keeping your solar panels in top condition is essential for maintaining energy efficiency and saving money. When production drops, the first clues often appear in your utility bills or monitoring data. Recognizing these key signs allows you to schedule timely solar repair services before minor issues escalate. Here are the top five signals it's time to reach out to trusted solar panel repair companies for an inspection and solar panel repair solutions.
⚠️ Unexpected Electricity Bill Spikes
If your energy bills suddenly jump without a change in weather or consumption, your system is underperforming and failing to offset your usage.
Action: Solar repair services or addressing underlying electrical issues can restore power production and lower your bills.
Pro Tip: Staying proactive with regular solar panel maintenance prevents small production leaks from turning into major problems.
⚠️ Significant Drop in Solar Energy Output
Your monitoring app is the most reliable diagnostic tool. If you see a clear, sustained drop in energy production that isn't due to shading or poor weather, a technical issue is likely present. A qualified solar repair service can diagnose the root cause:
Faulty or degraded wiring.
Inverter malfunction or failure.
Panel degradation or microcracks.
⚠️ Visible Damage to Panels or Loose Mounting Hardware
Physical damage is an immediate red flag that requires attention from solar panel repair companies.
Look for cracks, burn marks, discoloration, or corrosion on the panels themselves.
Check for rusted or loose racking/mounting hardware, which can be a safety risk and affect ventilation.
Solar panel repair companies can perform a thorough inspection, execute necessary repairs, and recommend preventative solar servicing to extend your system's longevity.
⚠️ Persistent Solar Inverter Error Codes
The inverter is vital. If it displays warning lights or error codes that persist after a simple system reset, it often indicates a need for professional inverter repair service.
Potential Issues: Internal component failure, connection issues, or voltage anomalies.
Solution: Professional solar repair services have specialized tools to diagnose and resolve these critical inverter problems safely and efficiently.
⚠️ Unusual Buzzing, Clicking, or Humming Noises
A healthy solar system is virtually silent. If you hear unusual sounds from your panels or inverter—like buzzing, clicking, or loud humming—this signals an immediate problem:
Common Causes: Loose connections or electrical arcing (sparking).
Safety First: Call a certified solar repair service right away. Experienced solar panel repair companies can quickly resolve these issues, often preventing serious damage or fire risk.
How to Handle Solar Panel Repair: DIY Maintenance vs. Professional Service
Maintaining your solar energy system doesn’t always require a professional, but knowing the line between simple homeowner tasks and essential professional solar repair services is critical. While some maintenance is safe and simple, complex issues should always be left to qualified solar panel repair companies. Here’s how to safely decide what you can handle and when to call a professional for solar panel repair solutions.
Safe DIY Solar Maintenance Tasks for Homeowners
A little preventative solar servicing can go a long way in maximizing system efficiency. These are basic tasks homeowners can confidently undertake:
Safely Cleaning Dirty Solar Panels - Keeping your solar panels clean is essential for optimal performance. Light cleaning of dust or debris using a soft cloth and water is something most homeowners can handle. Avoid harsh chemicals or abrasive tools that could damage the surface, and do not walk on the solar panels. Follow safety precautions, especially on steep or slippery roofs.
Checking for Loose Wiring or Connections - If you can safely access your system from the ground, look for obvious issues like loose wiring or slightly rusted brackets. You may tighten a loose screw (with the power off), but any complex wiring or unusual issues warrant a call to a professional solar repair service like GreenLancer.
When to Call a Professional Solar Repair Service
While basic DIY solar maintenance is helpful, numerous issues are too risky or complex for a homeowner to address. In these situations, professional support from certified solar panel repair companies is your safest and most cost-effective option.
Here’s when it’s best to bring in the pros:
Diagnosing Electrical Faults - Electrical issues, such as power surges or short circuits, can be tricky to identify and even riskier to fix. A professional solar repair service can perform diagnostic tests to ensure your system works correctly and safely.
Fixing or Replacing Damaged Panels - If your solar panels are cracked, discolored, or producing less energy, don’t try to repair them yourself. A qualified technician from one of the many trusted solar panel repair companies can evaluate the damage and make sure your system is safely restored.
Repairing or Replacing Inverters and Batteries - Inverters, batteries, and charge controllers are core components of your solar system (if you have battery backup). Diagnosing or replacing these parts incorrectly can damage your system or reduce efficiency. These types of solar repairs should always be handled by experienced technicians.
Protecting Your Solar Warranty - One of the biggest reasons to work with a professional solar repair service is to protect your manufacturer’s warranty. Most solar panel warranties require that repairs be done by authorized providers. DIY repairs or hiring unqualified help can void your coverage—and leave you paying out of pocket for future issues.
Solar Repair Service Costs
The cost of hiring a solar repair service depends on the issue's complexity, the system type, and the required parts. Most homeowners can expect to pay between $400 and $1,000 for common solar panel repairs, with averages around $750 for fixing issues like two cracked panels.
Minor repairs—like replacing a loose connector or fixing small electrical faults—can be as low as $120. On the other hand, major repairs, such as inverter replacement, can cost $2,000 to $3,000, depending on the model and system size. Full panel replacements or fixing widespread damage will naturally cost more, especially if multiple modules are involved.
