The Essential Guide to Understanding Solar Warranties

Solar Warranties

Navigating the complexities of solar warranties is crucial for homeowners venturing into the realm of sustainable energy. Solar panels are a substantial investment with various warranties, encompassing contractor commitments, manufacturer assurances, and innovative solutions like Solar Insure’s monitoring and warranty product.

Deciphering these warranties can be challenging, given the intricate technical and legal language often involved. This guide aims to demystify the landscape, offering homeowners a comprehensive understanding of the diverse warranty types.

From ensuring protection against defects to comprehending performance guarantees, this article is an indispensable resource for homeowners seeking clarity and confidence in their solar journey. Let’s explore the solar warranty terrain together.

Understanding Solar Contractor Warranties

Solar contractor warranties are essential to your solar energy system’s overall protection. These warranties, provided by the installer, generally cover workmanship and installation issues. They ensure the solar panels are correctly installed, and the system operates as intended.

Duration and Scope of Contractor Warranties

The duration of contractor warranties can vary. Some contractors offer warranties ranging from 1 to 10 years, while others provide 15 to 25 years. Typically, contractor warranties encompass issues like roof penetrations, wiring, workmanship, and the overall structural integrity of the installation. 

Trustworthy contractors demonstrate their faith in the system’s longevity by providing extensive warranties and standing behind the caliber of their work.

Solar Workmanship Warranties


A solar workmanship warranty provided by a typical licensed solar contractor covers the quality and integrity of the labor and solar installation work performed. 

This warranty ensures that the work meets industry standards and is free from defects in the workmanship of the solar project. 

Typically, it covers issues that arise due to improper installation, wiring, or poor workmanship rather than problems with the solar components used. The duration and specific terms of a workmanship warranty can vary, but it generally protects the homeowner from having to pay for repairs or adjustments due to errors or shortcomings in the contractor’s execution of the project.

Manufacturer Warranties

Manufacturer warranties are pivotal in securing homeowners’ solar investments by providing warranty coverage for essential components. Understanding the details of these warranties is crucial for informed decision-making.

Solar Panel Warranties

Solar panel manufacturers guarantee their products are free from material and workmanship flaws. Their warranty typically lasts for 10 to 25 years, offering extended coverage. 

Common Terms: Manufacturer warranties often cover defects in materials and workmanship, ensuring that the solar panels and inverters meet specific quality standards. Some warranties may have exclusions, such as damage caused by natural disasters or improper installation.

Production Warranties and Degradation Rate: Manufacturers guarantee a certain level of energy production through performance warranties. The output degradation rate signifies the annual reduction in panel efficiency. For instance, a 0.5% degradation rate means the panel retains 99.5% of its original output after one year.

Duration: Performance warranties, focusing on energy production, often extend for 25 years. Homeowners benefit from the assurance that their solar panels will maintain optimal performance over an extended period.

String Inverter Warranties

The warranty length for a typical string inverter can vary depending on the manufacturer and the specific model. Generally, the warranties for string inverters in the solar industry are as follows:

Standard Warranty Period: Most string inverters have a standard warranty period ranging from 10 to 12 years. This is the most common range manufacturers provide for residential and commercial installations.

Power optimizers, often used with string inverters in solar panel systems, also come with warranties. The warranty period for power optimizers is typically in the 25-year range.

Considerations: When evaluating the warranty of a string inverter, it’s essential to understand what the warranty covers. Some warranties might cover parts only, while others include labor and shipping costs.
The process of warranty claims and customer support efficiency are also critical aspects to consider.

Microinverter Warranties

Microinverter warranties are longer than those for traditional string inverters, reflecting their generally higher durability and longer expected lifespan. Here are some critical points about microinverter warranties:

Standard Warranty Period: Microinverters’ standard warranty period is typically 25 years. This extended duration is one of the selling points of microinverters, as it offers long-term assurance of their performance and reliability.

Coverage Details: Like other solar equipment warranties, it’s essential to understand what the microinverter warranty covers. Most cover manufacturing defects and performance issues. However, the specifics can vary between manufacturers, so reviewing the terms and conditions is crucial. They are also generally limited in labor coverage, covering only the first two years’ labor costs.

Ensuring Homeowner Protection

Manufacturer warranties play a pivotal role in safeguarding homeowners’ solar investments. These warranties provide financial protection and peace of mind by covering defects and ensuring a specified level of energy production. Homeowners can trust that their solar system components are backed by the manufacturer’s commitment to quality and longevity.

As solar panels are a substantial investment, understanding and leveraging manufacturer warranties contribute significantly to a homeowner’s confidence in the durability and reliability of their solar installation.

Gaps in Standard Solar Panel Warranties

Warranty Comparison

When delving into standard solar warranties, it becomes apparent that both contractor and manufacturer warranties have limitations and exclusions that warrant homeowners’ close attention. It is crucial to recognize these gaps to gain a comprehensive understanding of the protection these warranties offer.

Coverage Limits and Exclusions

Standard solar warranties, whether from contractors or manufacturers, have predefined limitations and exclusions that homeowners must know to grasp the full extent of the provided protection.

Contractor Warranties Limitations: While these warranties cover workmanship and installation quality, they often have predefined limits. Common exclusions may include damage caused by external factors like severe weather conditions, accidents, or homeowner interference.

Manufacturer Warranties Limitation: Despite assurances on solar components’ longevity and performance, manufacturer warranties may exclude certain conditions. 

For example, warranties may be voided if the solar panels are not installed according to specified guidelines or if unauthorized modifications are made. Certain solar panel warranties might not cover fire damage or other outside sources.

Labor Coverage: While manufacturers often provide warranties covering parts like panels, optimizers, and inverters, these warranties usually don’t cover the associated costs of labor and transportation (truck rolls) for repair or replacement. 

This means that while the defective part might be replaced free of charge or at a limited cost, the homeowner is generally responsible for the expenses related to the physical replacement process, including shipping and installation labor. 

These costs can be significant over the 30-year lifespan of a solar system, so homeowners should plan accordingly.

Transferability: Many solar component warranties are non-transferable or require an additional fee to transfer them to a new homeowner. The warranty benefits might not automatically extend to the new owner if the property is sold unless a transfer fee is paid or specific conditions are met. 

This is a crucial consideration for both current and prospective homeowners when evaluating the value and longevity of a solar energy system. It’s important for homeowners to understand the specific terms and conditions of their warranties to ensure continued coverage.

Scenarios Where Standard Warranties Fall Short

Standard warranties may need adequate coverage in some scenarios, leaving homeowners vulnerable to unforeseen circumstances.

Insolvency: If a solar component manufacturer faces financial difficulties or declares insolvency, the warranty commitments may become challenging to enforce. Homeowners should be aware of the financial stability of the entities offering warranties to mitigate risks associated with insolvency-related gaps.

If the contractor who provided the workmanship or performance warranty goes out of business, the warranty typically becomes void. Since the warranty is a promise from the contractor to fix certain issues, it depends on the contractor’s ability to honor that commitment. 

Without the business being operational, the homeowner usually has no recourse through that specific warranty. 

Limited Duration: Standard warranties have predefined durations, leaving homeowners unprotected beyond the warranty period. Issues arising after the warranty expiration may necessitate out-of-pocket expenses for repairs or replacements.

Recognizing these gaps allows homeowners to assess potential risks and explore supplementary solutions, such as extended warranties or specialized insurance products, to enhance the overall protection of their solar investments.

Dealing with Insolvency

Solar Bankruptcy

The looming threat of insolvency, whether from manufacturers or contractors, poses a significant challenge to the reliability of solar warranties, placing homeowners in a precarious situation. 

In the face of financial troubles, standard warranties may falter, leaving homeowners susceptible to potential gaps in coverage.

Manufacturer insolvency introduces risks to warranty fulfillment, subjecting homeowners to uncertainties and potential financial burdens. 

Likewise, if a solar contractor ceases operations, homeowner solar warranties may remain unattended, exposing them to vulnerable coverage points.

Investing in a solar energy system is a substantial commitment. Therefore, a robust contractor warranty is critical for safeguarding this investment for the long term. Selecting an installation with a track record of success and a dedication to client happiness is advised; this can be seen in the breadth and dependability of their warranty options.

This diligence ensures you know the coverage scope and potential limitations fully.

3. Review Duration and Specifics

A comprehensive warranty should cover an extended period, providing you with confidence in the durability of your solar investment. Assess the specifics of the warranty, including performance guarantees and protection against defects. Be cautious of any limitations or exclusions, and seek clarification on aspects that may impact the coverage over time.

4. Consider Additional Protection

Considering uncertainties tied to manufacturer and contractor insolvency, contemplating additional protection becomes paramount. Innovative solutions like Solar Insure’s monitoring and warranty product offer a safety net for your solar investment, assuring homeowners that their financial commitment is safeguarded even in challenging economic scenarios.
