Why a Solar Panel System Might Need Repairs

Solar energy systems are built for durability, but several factors can lead to the need for repairs. From extreme weather to aging components, understanding what can go wrong is the first step to protecting your investment.

Weather-Related Damage

Even the most robust solar panels can suffer when Mother Nature strikes. Hail, wind, heavy snow loads, and flying debris during storms can crack solar panel glass or loosen racking systems. Lightning strikes can fry electrical components like inverters or charge controllers, while prolonged UV exposure can gradually degrade panel materials and wiring insulation.

If your area experiences frequent storms or temperature extremes, the risk of weather-related damage increases significantly. Regular inspections following major weather events are highly recommended. If you believe your solar panel system has weather damage, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.

Electrical or Mechanical Failures

Your solar panel system relies on numerous electrical and mechanical parts working in harmony. Inverters, which convert solar DC power into usable AC power, are among the most common components to fail. Over time, even high-quality inverters may degrade or malfunction, especially if exposed to excessive heat or if their cooling systems fail. Loose connections, corroded terminals, or improperly installed components can cause ground faults or arc faults, which not only reduce performance but pose serious fire risks.

If your solar panel system is malfunctioning or you notice potential electrical or mechanical issues, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.

Manufacturing Defects

While rare, manufacturing defects in solar panels, inverters, or other components can sometimes go undetected during initial quality checks. Issues like poor soldering, delamination, or microcracks might not show up for months or years after installation.

Fortunately, these are often covered under product warranties. However, proper diagnosis and documentation are necessary for filing warranty claims, which is why professional assessment is key. If your solar panels or solar components show signs of manufacturing defects, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.

Animal and Pest Problems

Birds, squirrels, and rodents can sometimes be found nesting under solar panels, especially when there’s enough space between the panels and roof. These animals can chew through wiring or insulation, causing short circuits, outages, or even electrical fires. Nesting material can also accumulate under the solar panels, creating a potential fire hazard and causing solar panels to overheat and become less efficient. Bird droppings can also accumulate on panels, reducing energy absorption. Pigeon deterrents, critter guards, and regular inspections can prevent or identify pest-related damage early.

If your solar panels show signs of animal and pest issues, contact your solar company to have them assess the situation. You can also take precautionary measures to prevent the animals from causing issues in the future. Contact Green Ridge Solar if your solar company does not offer these services.

Age and Wear

Even the best solar equipment wears down over time. Systems over 10-15 years old may show signs of performance degradation, declining inverter efficiency, or aging connectors and wires. Rubber gaskets, junction boxes, and mounting hardware can also deteriorate due to constant exposure to sun, rain, and snow. Routine maintenance and timely repairs ensure your system continues to perform well into its third decade of use.

If your solar panels or solar components are showing signs of wear and tear, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.

Why Should You Repair a Solar Panel System?

Timely solar panel system repairs do more than restore function—they protect your energy savings, extend your system’s lifespan, and ensure your property remains safe and energy-efficient. Here are some of the top benefits of addressing solar panel system issues promptly.

Restoring System Efficiency

A malfunctioning solar panel, a broken inverter, or damaged wiring can significantly reduce your system’s energy output. For example, in string inverter setups, a single failed solar panel can lower the performance of an entire series. Even in systems with microinverters or optimizers, a faulty unit can quietly reduce overall production. By repairing or replacing these components quickly, you ensure you’re producing the maximum amount of solar energy possible—and saving as much as possible on your utility bills.

Protecting Long-Term ROI

One of the primary reasons homeowners and businesses invest in solar is the long-term return on investment (ROI). A system that’s not operating at full capacity of optimal efficiency due to neglected repairs chips away at those savings every day.

By keeping your solar panel system in good working order, you’re preserving your payback timeline and ensuring decades of financial benefit. Learn more about the typical payback period of solar panels, and use our Solar Calculator to estimate your solar savings.

Safety and Fire Risk Prevention

While they are uncommon, electrical faults in a solar panel system can be dangerous. Arc faults, ground faults, and overheating inverters can create fire hazards, especially on rooftops. Prompt repairs prevent minor issues from escalating into major safety threats. This is particularly important for commercial systems on public or high-traffic buildings, where safety risks are amplified.

Maintaining Warranty and Insurance Validity

Many solar component warranties require that systems be maintained properly. Ignoring necessary repairs may void warranty coverage, meaning you could be stuck paying out of pocket for replacements that otherwise would be covered. Similarly, home insurance policies may deny claims if it’s found that maintenance was neglected.

Enhancing System Lifespan

Just like regular oil changes keep your car running longer, routine solar repairs and maintenance ensure your system lasts as long as it should. With proper care, solar panels can exceed 25 years of service, while inverters can last 10–15 years or longer. A proactive approach to repairs ensures that timeline stays on track.

How are Solar Panel Systems Repaired?

Solar repairs vary widely depending on the problem, but the repair process generally involves three key steps: diagnosing the issue, performing the fix, and validating the system’s return to optimal performance.

Diagnostic Process

Diagnosing solar issues begins with visual inspection and system monitoring. Technicians check for visible damage to panels, racks, wiring, and connectors. They also analyze production data from monitoring portals to identify anomalies such as a sudden drop in output or inverter faults. Tools such as thermal imaging cameras can detect overheating components, while IV curve tracers and multimeters help pinpoint electrical issues like shorts or resistance problems. Communication errors are also assessed, especially when monitoring systems show a system as “offline.”

Common Repairs and Fixes

• Panel Replacement: Cracked or delaminated panels are swapped with new units, ensuring they match the system’s voltage and wattage.
• Inverter Swap or Reprogramming: Inverters are tested, repaired, or replaced. Inverter error messages are used to diagnose the potential issues with the equipment. If replacement is needed, new inverters are configured and integrated with existing systems.
• Wiring Repairs: Damaged or degraded wiring is replaced, and connections are re-secured and sealed against moisture.
• Mounting Adjustments: Loose or damaged racking systems are reinforced or replaced to ensure panels are secure and correctly angled.
• Monitoring and Communication Fixes: Issues with Wi-Fi connections, data loggers, or cloud platforms are addressed, sometimes requiring firmware updates or component replacements.

Timeframes and Costs

Minor repairs like replacing connectors or reprogramming an inverter may take only an hour or two. More complex issues, such as swapping a failed inverter or replacing multiple panels, may require a day or more. Costs can vary based on component prices, labor rates, and warranty coverage. A trusted solar repair company will provide a detailed estimate upfront and help determine whether costs are covered under existing warranties.

If your solar panels or solar components need to be diagnosed, repaired, or replaced, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.

Seek Experts for Safe, Timely Solar Repairs

Many homeowners and businesses assume their solar system will operate flawlessly year after year—and often it does. But just like any other electrical system, problems can develop over time, sometimes quietly and without warning. In many cases, the first signs of trouble are only noticed after monthly utility bills creep up or a system monitoring platform signals a dip in performance.

Proactive inspections and expert evaluations are key to catching these issues early. Whether it’s a loose wire, a faulty inverter, or a cracked panel, early detection and repair can prevent larger, more costly breakdowns. In the next sections, we’ll walk through the most common warning signs to watch for, why DIY fixes are risky, and the value of partnering with a trusted solar repair expert.

Warning Signs Homeowners Should Watch For

• Unusual Utility Bills: A sudden spike in electric bills may signal that the system isn’t producing as it should.
• Monitoring System Errors: Alerts or an offline status from your monitoring platform are red flags.
• Visible Damage: Cracked panels, hanging wires, or sagging racking systems are clear signs to call for repair.
• Odd Sounds or Smells: Buzzing from the inverter or a burning smell near system components should be investigated immediately.

Why DIY Solar Repair Isn’t the Answer

While it might be tempting to climb on the roof and inspect your panels yourself, solar systems involve high-voltage electricity and delicate components. Mistakes can lead to electrocution, fire risk, or voided warranties. Qualified solar professionals have the tools, training, and certifications needed to safely and effectively diagnose and repair systems.

Proactive Steps to Avoid Solar Panel Repairs

While some solar system issues are simply inevitable over time, many costly solar repairs can be avoided through proactive maintenance and smart usage practices. Routine inspections, cleanings, and monitoring can go a long way toward keeping your solar panel system running at peak efficiency while identifying small issues before they become expensive problems. By integrating a few simple habits and professional checkups into your solar routine, you can safeguard your investment and ensure years of uninterrupted performance.

Annual Inspections and Preventive Maintenance

Scheduling a professional solar inspection once a year is one of the most effective ways to preserve the health of your solar system. These visits typically include panel cleanings to remove dirt, dust, and debris that can block sunlight, as well as detailed checks of wiring, junction boxes, and electrical connections. Technicians will test inverter output, inspect racking and mounting hardware for wear or corrosion, and look for signs of damage from pests, moisture, or thermal cycling. Identifying a cracked panel, loose wire, or degraded seal early can mean the difference between a minor adjustment and a major repair.

In addition to professional inspections, some preventive maintenance tasks, such as visually checking for debris buildup or nesting animals, can be performed by the homeowner from the ground level. However, any work involving electrical components or climbing onto the roof should always be left to trained professionals.

Monitoring System Alerts

If your solar panel system includes a performance monitoring platform, it can act as your first line of defense against developing issues. These systems track energy production in real time and can flag anomalies such as a sudden drop in output, inverter failure, or connectivity problems. Some solar monitoring platforms can even alert both the homeowner and the installer, allowing for rapid diagnosis and service calls when necessary.

For systems that don’t include monitoring, upgrading to a smart monitoring platform can be a worthwhile investment. Not only do they provide transparency into your system’s performance, but they also allow for quicker responses to potential faults, reducing downtime and ensuring your solar panels are always working to their full potential.

If you notice performance issues or alerts within your solar monitoring software, contact your solar company to have them assess the situation. Contact Green Ridge Solar if your solar company does not offer post-install services.
