Although solar panels are reliable and maintenance-free, it is always desirable to be covered for defects and problems. Solar panel warranties are essential when considering the purchase of a solar energy system. A good solar panel warranty can provide peace of mind and assurance that the panels will perform as expected for a specified period. As in any industry, solar panel warranties vary by what they cover and how long the coverage lasts.
Here’s everything you need to know about solar panel warranties:
Types of Warranties in Solar Panels
There are two main types of warranties offered for solar panels:
Product Warranty: This covers defects in the materials and workmanship of the solar panels.Such warranties are offered typically for 5 years. Good manufacturers offer upto 10 years product warranties.
Performance Warranty: Performance warranties offer a certain level of power output over an extended period of time. It assures that the panels will still produce a specified percentage of their rated power output after a certain number of years. Performance warranties are generally provided over a period 25 years.
The fundamental question here is: What specific item does the warranty encompass?
In any machinery, with passage of time the performance begins to decline progressively. It is inevitable and dependent on various factors. As solar panels are exposed to the external environment, such progressive decline has to be expected.
Manufacturers test the solar panels under stringent test conditions to simulate the decline and warrant for a minimum output from solar panels over a period of time. Customers, are thus assured that the decline in the efficiency and output are not beyond the certified limits.This is usually 90% of specified output for the first 10 years and 80% of specified output over the subsequent 15 years for most manufacturers.
LUBI Electronics offers solar panels with a performance warranty of more than 93% of the specified output for the first 10 years and more that 84% of specified output of the module for the subsequent 15 years. The solar panels come with an additional 10-year product warranty, which covers against any defects related to workmanship.
Solar panel warranties are provided by the panel manufacturers, for products that are traceable to a valid transfer document. The scope of coverage may differ from one manufacturer to another, so it’s crucial to review the warranty document to understand the specifics. Solar panel warranties are typically non-transferable, meaning they apply only to the original purchaser.
Factors Affecting Warranty Claims
Misuse or Abuse: Any damage caused by improper installation, maintenance or handling not in accordance with the manufacturer’s guidelines and any physical damage due to external impact may void the warranty.
Acts of Nature: Warranties might not cover damage caused by natural disasters like hailstorms, floods, or earthquakes. Though solar panels are manufactured to withstand sizeable mechanical loads or shocks, any damage resulting from natural disasters are not covered under standard warranties. Such cases can be covered under an insurance policy.
Unauthorized Modifications: Any alterations or repairs performed by unauthorized personnel can void the warranty. Any DIY installation or repairs will void the warranty. It is always wise to engage a reputed installation company, who have required credentials and experience.
How to Make a Warranty Claim
If you encounter an issue covered by the warranty, you should contact your solar panel installer or service provider. In the event that your installer is no longer in operation, take the initiative to investigate if they have been acquired by another solar company. Otherwise, contact the manufacturer of the solar panel and explain the situation and ask for assistance.
Be prepared to provide information about the system’s installation date, serial numbers of the affected panels, and evidence of the issue, such as monitoring data showing reduced power output.
Some manufacturers require regular system monitoring to be eligible for warranty claims. Monitoring helps identify performance issues early on.Regular maintenance may also be necessary to keep the warranty valid. Maintenance tasks might include cleaning the panels and checking connections.
It’s crucial to choose solar panels from reputable manufacturers with a proven track record of honoring warranty claims. Some solar installers offer workmanship warranties, which cover the installation process. These warranties are separate from the manufacturer’s warranties.
In summary, when purchasing solar panels, pay close attention to the product and performance warranties provided by the manufacturer. Ensure you understand the warranty coverage, the factors that could void the warranty, and any additional requirements for maintaining warranty eligibility. A reliable solar panel warranty can safeguard your investment and ensure the longevity of your solar energy system.
