Tesla Solar Warranty Explained (2025): What's Covered and How Long It Lasts

Introduction

Thinking about going solar with Tesla? One of the most important questions homeowners ask is: "What does the Tesla solar warranty cover, and for how long?" In this detailed guide, we’ll break down everything you need to know about Tesla’s solar warranties, from product coverage to performance guarantees — helping you make a confident investment in clean energy.

What is the Tesla Solar Warranty ? 

Tesla offers a comprehensive solar warranty that covers their solar panels, Solar Roof, and Powerwall products. The warranty protects you against defects, ensures system performance, and provides peace of mind for years after installation.

Tesla’s solar warranty typically includes three key components:

• Product Warranty

• Performance Warranty

• Workmanship Warranty

Tesla Solar Panel Warranty

1. Product warranty

Tesla’s solar panels come with a 25-year product warranty. This warranty covers:

• Manufacturing defects

• Equipment failures

• Material quality issues

If your Tesla solar panels malfunction due to a manufacturing defect, Tesla will repair or replace the faulty panels at no extra cost.

2. Performance Battery 

Tesla guarantees that their solar panels will perform at a certain efficiency level over time:

• At least 80% power output at Year 25

This means your solar panels will not lose more than 20% of their generating capacity over 25 years, ensuring long-term energy production.

Tesla Solar Roof Warranty 

The Tesla Solar Roof also comes with robust warranties:

• 25-Year Tile and Power Output Warranty: Covers the solar glass tiles and guarantees energy production.

• 10-Year Comprehensive Warranty: Covers everything from installation to leaks and weather-related damage.

Tesla’s Solar Roof is built to withstand extreme weather conditions, including hail and high winds, and the warranty ensures that Tesla will fix or replace any defective tiles.

Tesla Powerwall Warranty

If you install a Tesla Powerwall along with your solar system, Tesla provides:

• 10-Year Warranty
  The Powerwall warranty covers defects and ensures that the battery will maintain a minimum energy capacity (usually around 70% of its original capacity) for up to 10 years.
  

Workmanship Warranty

Tesla also backs its installations with a 10-year workmanship warranty.
This covers:

• Roof penetrations

• Mounting system

• Electrical work

If any issues arise from the installation itself, Tesla will handle the necessary repairs.

What isn't Covered

While Tesla’s warranty is comprehensive, it does not cover:

• Damage caused by natural disasters (unless otherwise specified)

• Third-party modifications or repairs

• Cosmetic issues that don’t impact performance

• Normal wear and tear

It’s important to carefully read Tesla’s warranty documents and discuss any concerns with your installation team.

When you invest in a Tesla solar system, you’re not just getting high-quality products — you’re getting decades of protection.
Here’s why Tesla’s warranty stands out:

• Industry-leading 25-year coverage

• Support from Tesla’s trusted service network

Choosing Tesla means choosing long-term energy savings, reliability, and support.
