Installing solar panels is a major decision, and many homeowners wonder if the warranties really protect them. While solar panels are built to last, problems can still occur, and understanding warranties can save you both money and stress. In this article, we explain everything, and we provide practical examples to show how solar panel warranties work in real life.

What is a Solar Panel Warranty?

A solar panel warranty is a promise from the manufacturer that your panels will work as expected for a certain period. There are usually two types: performance warranties and product warranties. Performance warranties guarantee that the panels will produce a certain percentage of their rated output after a number of years, while product warranties cover defects or failures in materials and workmanship.

You should always check both, and also see if the warranty is transferable if you sell your house.

How Long Do They Last?

Most solar panels come with a 25-year performance warranty and a 10–12 year product warranty. Some premium brands extend the product warranty to 20–25 years. Longer warranties usually indicate better quality, but you should read the fine print, because some warranties exclude certain damages or require specific maintenance.

Therefore, you must follow all manufacturer instructions, or the warranty could become void.

What Is Covered?

Warranties generally cover two main issues. First, power output: the panels should produce at least 80–90% of their rated power after 25 years. Second, material and workmanship defects: if a panel breaks or develops a defect, the manufacturer replaces it. However, damage from storms, hail, or improper installation usually isn’t included. That’s why installing panels through certified professionals matters, and AceFlex GmbH ensures proper installation for full coverage.

Common Warranty Questions

Homeowners often ask how claims work and whether they are hassle-free. Typically, you contact the manufacturer or your installer, provide proof of purchase, and they inspect the issue. Some warranties cover shipping costs, while others require you to pay. Since processes vary, you should always document your installation and maintenance to avoid disputes.

Also, some warranties are prorated, which means you receive only part of the cost after many years.

Example: Solar Panel Performance Over Time

Here’s a visual representation of expected performance over 25 years:

Year Expected Output (%)
0 ██████████████████████ 100%
5 ████████████████████ 98%
10 ██████████████████ 95%
15 ████████████████ 92%
20 █████████████ 88%
25 ███████████ 80%

This shows a gradual decrease in performance, which is why both performance and product warranties are important. A defective panel early on can affect your overall system efficiency.

Why Warranties Matter

Warranties protect your investment, and they provide peace of mind. Since solar panels are expensive, knowing you have support if something goes wrong reduces financial risk. Also, combining good warranties with professional installation ensures long-term performance, and AceFlex.us provides both.
