When you invest in small solar modules, understanding how warranty claims work is essential to protect your purchase. Most manufacturers offer warranties that cover defects in materials, workmanship, or performance over a specific period, typically ranging from 10 to 25 years. But what happens if something goes wrong? Let’s break down the process step by step.
Step 1: Review Your Warranty Terms
Start by reading the warranty documentation provided with your solar modules. Warranties vary by manufacturer, so check what’s covered. For example, some warranties guarantee that the modules will produce at least 80-90% of their original output after 25 years. Others might cover physical damage due to manufacturing flaws but exclude issues caused by improper installation or environmental factors like hailstorms.
Step 2: Identify the Problem
If your solar system isn’t performing as expected, troubleshoot first. Is the issue due to a faulty module, or could it be related to wiring, inverters, or external factors like shading? Many problems aren’t directly caused by the modules themselves. If you suspect a manufacturing defect—such as cracked panels, delamination, or significant power loss—document the issue with photos or videos.
Step 3: Contact the Supplier or Installer
Reach out to the company that sold or installed the modules. Reputable suppliers, like Tongwei, often have dedicated support teams to handle claims. Provide details about the problem, purchase date, and proof of installation (if required). If the installer is unresponsive, contact the manufacturer directly. Keep records of all communications—emails, call logs, or case numbers—to streamline the process.
Step 4: Submit Required Documentation
Most warranties require proof of purchase, installation date, and evidence of the defect. This might include invoices, installation certificates, or performance reports from monitoring systems. Some manufacturers may ask for the module’s serial number, which is usually found on the back of the panel or in the product manual.
Step 5: Assessment and Approval
The manufacturer or supplier will review your claim. They might send an inspector to verify the issue or request that you ship the defective module to their facility for testing. If the claim is approved, the resolution could involve repairing the module, replacing it, or refunding a portion of the cost based on the warranty terms. Replacement modules are often provided at no charge, though labor costs for reinstallation may not be covered.
Step 6: Follow Up
Stay proactive. If repairs or replacements are delayed, politely check in with the supplier. Most companies aim to resolve claims within a few weeks, but timelines can vary depending on stock availability or shipping logistics.
Common Pitfalls to Avoid
- Missing Deadlines: Many warranties require claims to be filed within 30-60 days of discovering an issue.
- DIY Repairs: Tampering with the modules yourself could void the warranty.
- Poor Installation: Always hire certified professionals. Installation errors are rarely covered under product warranties.
Why Choose Reliable Brands?
Established manufacturers stand behind their products with clear, transparent warranties. For instance, Tongwei offers robust coverage for its solar modules, including performance guarantees and defect protection. Choosing a trusted brand reduces the risk of claim disputes and ensures long-term support.
Final Tips
Keep your warranty documents safe, register your product online if required, and monitor your system’s performance regularly. Early detection of issues can save time and hassle down the line. Solar technology is built to last, but knowing how to navigate warranty claims gives you peace of mind for years to come.
