A Comprehensive Guide to Solar Panel Repair

SolarSusan Rai

Solar power has become an increasingly popular source of energy that is both beneficial to the environment and often cost-efficient. Homeowners have begun taking advantage of solar panel technology, whether through rooftop installations or by adding panels to existing outdoor structures such as barns and garages. But just like with any other system set up within a home, repairs will eventually be needed for adequate maintenance and continued sustainability. Before you embark on fixing your solar panel setup yourself or hiring a professional repair service, it’s important to know what issues could arise, what types of repairs you may need, how much they typically cost—and who’s responsible for covering it all! In this blog post, we will guide you through these aspects, providing valuable information, so you can make informed decisions on maintaining your setup over time.

How to Know if Your Solar Panel Needs Repair?

To ensure your solar panel system operates optimally, it's important to recognize the signs that indicate when repair is necessary. Here are a few key indicators that your solar panel might need repair:

  • Decreased Energy Output: If you notice a significant drop in energy production, it could be a sign of a malfunctioning panel.
  • Physical Damage: Cracked or broken glass, loose connections, or damaged frames are clear signs of physical damage that require attention.
  • Water Leakage: Water infiltration can lead to corrosion and electrical damage, indicating the need for repair.
  • Faulty Inverter: If your inverter is not converting DC to AC power efficiently or if it's displaying error messages, it might be time for a repair.


What are the Common Solar Panel Issues?

If you find some signs showing your solar panels need repair, you may wonder what are the common issues that result in a decreased energy output or physical solar panel damage. Although solar panels are built to withstand various environmental conditions, they can still encounter several common issues. Some common solar panel issues include:

  • Hotspots: Occur when a portion of the panel becomes significantly hotter than the rest due to cell damage or shading.
  • PID (Potential-Induced Degradation): A phenomenon where voltage leakage causes reduced performance and power output.
  • Microcracks: Hairline cracks that may develop over time due to thermal cycling or mechanical stress.
  • Panel Soiling: Accumulation of dirt, dust, or debris on the panel surface, reducing energy absorption.
  • Wiring Issues: Poor connections, damaged wires, or loose terminals can impact panel performance.

By being aware of these common issues, you can better monitor the health of your solar panel system and address problems promptly to avoid further damage.

Can the Damaged Solar Panel be Repaired?

For most cases that we have mentioned above, the answer is yes, damaged solar panels can be repaired. However, the extent of the damage and the age of the panels play a significant role in determining whether the repair is feasible. For minor issues like loose connections or small cracks, repairs can often be carried out successfully.

Professional solar panel repair technicians have the expertise and equipment to diagnose and fix various problems. They can replace damaged components, fix wiring issues, or reseal panels to prevent water infiltration. However, it's important to note that severe physical damage, extensive microcracks, or complete panel failure may require panel replacement instead of repair.

How Much Does Repairing Solar Panels Cost?

The cost of repairing solar panels can vary depending on the type and extent of the damage, as well as the region and specific service provider. It's important to understand the different cost components associated with solar panel repairs:

Costs of Solar Panel Repair

The repair costs for solar panels can vary depending on several factors, including the severity of the damage and the complexity of the repair required. Generally, the range for repair costs is between $150 and $1000.

Minor issues, such as loose connections or small cracks, usually fall on the lower end of the price range. These types of repairs may involve simple fixes like tightening electrical connections or applying sealant to small cracks. The cost for such repairs typically falls around $150 for the solar panel system.

However, more extensive damage can result in higher repair costs. For instance, if a solar panel sustains significant damage due to severe weather conditions or physical impact, the repair process may involve replacing damaged components or even the entire panel. These types of repairs often require more labor and materials, driving the costs up. As a result, the repair costs for the solar panel system with extensive damage may reach the higher end of the price range, around $1000.

Costs of Solar Inverter Repair

If the inverter of a solar panel system requires repair or replacement, the cost can indeed vary based on factors such as the size and type of the inverter. Generally, the cost for inverter repair or replacement can range from $1000 to $2,000.

The size of the inverter plays a significant role in determining the cost. Larger inverters, designed for systems with higher power output capacities, tend to be more expensive to repair or replace compared to smaller inverters.

The type of inverter also influences the cost. There are different types of inverters available in the market, such as string inverters, microinverters, and power optimizers. Each type has its pricing structure based on factors like efficiency, durability, and advanced functionalities. In general, microinverters and power optimizers can be more expensive to repair or replace compared to string inverters.

Costs of Solar Battery Repair

If you have a solar battery system and it requires repair, the cost can range from $300 to $7,500, depending on the battery type and capacity.

There are various types of solar batteries available, including lead-acid, lithium-ion, and flow batteries. Among them, lithium-ion batteries are commonly used in solar energy storage systems due to their high energy density and longer lifespan. However, they can be more expensive to repair compared to lead-acid batteries.

Besides, larger-capacity battery systems will typically have higher repair costs due to the larger number of cells or modules involved.

Other factors that can affect the repair cost include the complexity of the repair required, the age of the battery system, and the availability of replacement parts.

Who Should Take Responsibility for the Solar Panel Repair Cost?

Determining who should bear the responsibility for solar panel repair costs depends on various factors, including warranty coverage, the age of the panels, and the cause of the damage.

If your solar panel system is under warranty, the repair costs may be covered by the manufacturer or installer. Some reliable solar panel manufacturers like Anker, and Jackery usually provide long-term warranties, typically covering defects in materials or workmanship for a specified period, which can range from 10 to 25 years.

If the damage is due to improper installation or a manufacturing defect, the responsibility may fall on the installer or manufacturer.

However, if the damage is a result of natural causes, such as severe weather events or wear and tear over time, the responsibility for repair costs may rest with the system owner. It's crucial to review your warranty terms and consult with the installation company to determine the coverage and responsibility for repair costs.


Final Thoughts

Regular maintenance and timely repair are essential for maximizing the lifespan and efficiency of your solar panel system. By understanding the signs that indicate repair is needed, common issues you may encounter, and the costs involved, you can take proactive measures to keep your system in optimal condition.

Remember to consult professional solar panel repair technicians for accurate diagnosis and repair. Finally, review your warranty terms and clarify responsibility for repair costs with the installation company to ensure you're prepared for any potential repairs.
