Solar panel warranties are an essential aspect of investing in solar energy systems. A good warranty provides peace of mind and assurance that your solar panels will continue to generate power effectively over time. In this blog post, we will explore the different types of solar panel warranties, coverage, typical warranty lengths, the claims process, and additional considerations to help you make an informed decision.
Types of Solar Panel Warranties
There are two main types of warranties for solar panels: equipment warranties and performance warranties.
- Equipment Warranties cover manufacturing defects, material problems, and premature equipment failure. They ensure that the solar panels themselves are free from defects and function correctly.
- Performance Warranties guarantee that the solar panels will maintain a certain level of power output over a specified period. These warranties ensure that solar panels continue to generate power efficiently and may include degradation rate guarantees.
Solar Panel Warranty Coverage
Solar panel warranties typically cover:
- Manufacturing defects
- Premature equipment failure
- Power output guarantees
Warranty coverage may vary based on the manufacturer and type of solar panel, so it is essential to read and understand the specific terms and conditions of your warranty.
Solar Panel Warranty Length
The length of a solar panel warranty can range from several years to multiple decades, depending on the type of warranty and the manufacturer. Here are some general guidelines regarding warranty lengths:
- Equipment Warranties typically last between 10 and 25 years
- Performance Warranties usually guarantee 90% of rated power output for the first 10-12 years and 80% for the following 10-18 years
Please note that these lengths may vary, so always verify the specific warranty length for your solar panels.
Solar Panel Warranty Claims
When filing a warranty claim for your solar panels, you should:
- Review the warranty terms and conditions to ensure your issue is covered
- Gather all relevant documentation, such as proof of purchase, installation records, and maintenance history
- Contact the solar panel manufacturer or installer to initiate the claim process
- Provide the requested documentation and wait for a response, which may take several weeks
When evaluating solar panel warranties, also consider the following factors:
- Manufacturer and Installer Reputation: Choose a reputable company with a history of upholding warranty claims and providing reliable products.
- Environmental Factors: Understand the impact of local weather conditions and other environmental factors on solar panel performance. Some warranties may not cover damage due to extreme weather or external factors.
Solar panel warranties are an essential aspect of your solar energy investment. To choose the best warranty for your needs, carefully review the types of warranties, coverage, length, claims process, and additional considerations. By selecting a warranty from a reputable manufacturer and installer, you can ensure your solar panels provide clean, reliable energy for years to come.
