Investing in solar panels is a significant decision for homeowners, and it’s natural to wonder about the warranties and guarantees that come with these systems. Solar panels are designed to be durable and long-lasting, but it’s important to have peace of mind regarding their performance and reliability. In this blog post, we will discuss the warranties and guarantees typically offered for solar panels and what homeowners should consider when evaluating their options.

 

  1. Manufacturer’s Product Warranty

Most reputable solar panel manufacturers offer product warranties that cover the panels against defects in materials and workmanship. These warranties typically range from 10 to 25 years, with some manufacturers offering even longer coverage. Here are the key aspects of a manufacturer’s product warranty:

  • Coverage: The product warranty ensures that the solar panels will perform within specified parameters and remain free from defects that could impact their functionality.
  • Duration: The duration of the product warranty varies by manufacturer but is generally between 10 and 25 years. It’s important to review the warranty terms and understand the coverage period provided.
  • Remedies: In case of a covered defect or performance issue, the manufacturer will typically repair or replace the faulty panels at no cost to the homeowner.

When evaluating different solar panel brands, it’s crucial to consider the length and coverage of the product warranty. Opting for a manufacturer with a solid reputation and a comprehensive product warranty can provide peace of mind and ensure the long-term performance of your solar panel system.

  1. Performance Warranty

In addition to the product warranty, solar panels often come with a separate performance warranty. The performance warranty guarantees that the panels will continue to generate electricity at a specified level over a certain period. Here are the key aspects of a performance warranty:

  • Guaranteed Performance: The performance warranty typically guarantees that the solar panels will maintain a certain level of power output (usually a specified percentage of their initial power) over the warranty period.
  • Duration: Performance warranties are commonly offered for 25 to 30 years, although some manufacturers may provide longer durations.
  • Remedies: If the solar panels do not meet the specified performance levels, the manufacturer will usually compensate the homeowner for the underperformance through various means. This may involve either replacing the underperforming panels or providing financial compensation based on the lost power output.

It’s important to carefully review the terms and conditions of the performance warranty, including any degradation rates specified, as these details will determine the extent of coverage and potential remedies.

  1. Installer Workmanship Warranty

Aside from the warranties provided by the panel manufacturer, reputable solar installers often offer workmanship warranties. These warranties cover the installation process and ensure that the system is installed correctly. Key points to consider about installer workmanship warranties include:

  • Coverage: The workmanship warranty typically covers any issues arising from improper installation, such as leaks, electrical problems, or other installation-related faults.
  • Duration: Installer workmanship warranties can vary but are commonly offered for 5 to 10 years.
  • Remedies: In case of installation-related issues, the installer will be responsible for repairing or rectifying any problems covered by the workmanship warranty.

Selecting an experienced and reputable solar installer is crucial, as their workmanship warranty will ensure that any potential installation-related issues are addressed promptly and at no additional cost to the homeowner.

Solar panels come with warranties and guarantees that provide homeowners with assurances regarding the product’s quality, performance, and installation. When evaluating different solar panel options, it’s essential to consider the length and coverage of the manufacturer’s product warranty, the performance warranty, and any workmanship warranty offered by the installer.

Choosing reputable manufacturers and installers with a proven track record is crucial to ensure that the warranties provided are reliable and that any potential issues are promptly resolved. By understanding and considering the warranties and guarantees associated with solar panels, homeowners can make informed decisions and have confidence in the long-term performance and reliability of their solar panel system.
