How do I Know What is Covered Under my Solar Warranty?

One important aspect of protecting your solar investment is understanding the coverage provided by your solar warranty. A solar warranty is a crucial component that ensures your panels and system are protected against defects, performance issues, and installation problems. In this article, we will help you navigate through the intricacies of solar warranties and shed light on what is typically covered under them.

Product Warranty:

The product warranty primarily covers the solar panels themselves and guarantees their performance and durability. It usually ranges from 10 to 25 years, depending on the manufacturer. This warranty protects you against defects in materials and workmanship. If your solar panels fail to perform or experience issues during this period due to manufacturing defects, the manufacturer will usually cover the cost of repair or replacement.

Performance Warranty:

The performance warranty focuses on the power output of your solar panels over time. Solar panels naturally experience a slight decrease in efficiency, known as degradation, as they age. The performance warranty assures that the panels will maintain a certain level of power output during a specified period, usually ranging from 25 to 30 years. If your panels fall below the specified threshold, the manufacturer or installer will typically provide remedial action, which may include repair or replacement of underperforming panels.

Inverter Warranty:

Inverters are critical components of your solar system that convert the direct current (DC) electricity generated by the panels into usable alternating current (AC) electricity for your home. Most inverters come with their own warranty, typically ranging from 5 to 15 years. This warranty covers defects or malfunctions in the inverter and may include repair or replacement services. It’s important to understand the inverter warranty as it is a separate component from the solar panels themselves.

Installation Warranty:

An installation warranty covers any issues arising from the installation process, including faulty wiring, inadequate mounting, or related workmanship problems. The duration of an installation warranty varies among installers but is typically around one to five years. If any issues arise due to installation errors, the installer should cover the cost of rectifying the problem.

Exclusions and Limitations:

While solar warranties provide valuable coverage, it’s important to understand their limitations and exclusions. Common exclusions may include damage caused by extreme weather events, accidents, improper maintenance, or unauthorized repairs. Additionally, warranty coverage may be voided if the panels or system were tampered with or installed by unauthorized personnel. Always review the warranty documentation thoroughly to understand the specific terms and conditions that apply to your solar system.

Warranty Transferability:

If you decide to sell your home with solar panels, it’s important to check if your solar warranty is transferable to the new homeowner. Some warranties may allow for transfer, while others are non-transferable. Understanding the transferability provisions can add value to your property and provide peace of mind to potential buyers.

Documentation and Communication:

Keep all warranty documentation and relevant paperwork in a safe place for future reference. If you have any questions or concerns about your warranty coverage, don’t hesitate to reach out to Volta Solar Energy’s customer support team. They can provide clarification and guidance regarding your specific warranty terms.


Understanding the coverage provided by your solar warranty is essential for protecting your solar investment. Knowing what is covered and what is not can help you make informed decisions and ensure the long-term performance and durability of your solar panels. Remember to review the warranty documentation thoroughly, communicate with your solar provider, and take proper maintenance measures to maximize the benefits of your solar system.
