Solar panels are a significant investment, and it’s important to protect that investment by choosing the right warranty. One type of warranty that is commonly offered for solar panels is the power output warranty. In this article, we’ll explore what power output warranties are, what to consider when choosing a warranty, and whether they are worth the investment.
What is a power output warranty?
A power output warranty is a guarantee that the solar panels will produce a certain level of power over their lifetime. This warranty typically guarantees that the panels will produce a certain percentage of their rated power output over a specific period, such as 25 years. For example, a 25-year power output warranty may guarantee that the panels will produce at least 80% of their rated power output after 25 years of operation.
What are the different types of power output warranties?
There are two main types of power output warranties: linear warranties and flat warranties.
Linear warranties guarantee that the panels will degrade at a predictable rate over their lifetime. This means that if the panels are expected to degrade by 1% per year, the warranty will guarantee that the panels will produce a certain percentage of their rated power output each year. For example, a linear warranty may guarantee that the panels will produce at least 97% of their rated power output in year 1, 96% in year 2, and so on.
Flat warranties guarantee that the panels will maintain their power output level over their lifetime. This means that the warranty will guarantee that the panels will produce a certain percentage of their rated power output at all times. For example, a flat warranty may guarantee that the panels will produce at least 80% of their rated power output for the entire warranty period.
What are the key considerations when choosing a power output warranty?
When choosing a power output warranty for your solar panels, there are several factors to consider:
Length of warranty: The longer the warranty period, the more protection you have for your investment.
Type of warranty: Linear warranties are typically better for panels that are expected to degrade more quickly, while flat warranties are better for panels that are expected to maintain their output over time.
Warranty terms: Be sure to read the warranty terms carefully to understand what is covered and what is not. Some warranties may have specific requirements for installation or maintenance that must be followed to keep the warranty valid.
Manufacturer reputation: Look for a reputable manufacturer with a track record of producing high-quality panels and honoring their warranties.
Cost: Consider the cost of the warranty when deciding whether it is worth the investment. Extended warranties may cost more but can provide added protection for your investment.
Can power output warranties be transferred to a new owner?
In many cases, power output warranties can be transferred to a new owner if the property is sold. This can be a valuable selling point for properties with solar panels installed.
What is the process for making a warranty claim?
If you believe that your solar panels are not meeting the power output level specified in the warranty, you should contact the manufacturer or installer to initiate a warranty claim. The manufacturer will typically require proof of purchase and may require an inspection of the panels to determine the cause of the issue.
How to ensure your solar panel warranty is valid?
To ensure that your solar panel warranty remains valid, it’s important to follow the manufacturer’s instructions for installation, maintenance, and operation. This may include regular cleaning, monitoring of power output levels, and ensuring that the panels are installed in a location that receives adequate sunlight.
Do power output warranties cover all solar panel brands?
No, power output warranties do not cover all solar panel brands. Each manufacturer has its own warranty terms and conditions, so it’s important to research and compares different brands and their warranty offerings before making a purchase.
Conclusion
Power output warranties are an important consideration when investing in solar panels. They provide peace of mind that your investment will continue to provide reliable power output over its lifetime. When choosing a power output warranty, consider the length of the warranty, the type of warranty, the warranty terms, the manufacturer’s reputation, and the cost. By choosing the right warranty, you can protect your investment and ensure that your solar panels continue to provide reliable power for years to come.
