Solar Panel Warranties

  1. Types of Warranties
    • Product Warranty: Covers defects in materials and workmanship of the solar panels. Typically ranges from 10 to 25 years.
    • Performance Warranty: Guarantees  the panel’s performance level (e.g., efficiency degradation). Usually covers 25 to 30 years.
  2. Key Warranty Terms
    • Coverage: Understand what aspects of the panel’s performance and quality are covered.
    • Duration: Check the length of the warranty for both product and performance.
    • Guarantee Levels: Some warranties guarantee a minimum power output percentage over time (e.g., 80% after 25 years).
  3. Conditions and Exclusions
    • Installation Requirements: Panels must be installed according to manufacturer specifications.
    • Environmental Factors: Warranties may exclude damage from extreme weather or improper handling.
    • Manufacturer Requirements: Follow maintenance guidelines and use approved components.
  4. Transferability
    • Determine if the warranty can be transferred to a new homeowner if you sell your property.
  5. Manufacturer Reputation
    • Choose panels from reputable manufacturers known for honoring warranties and providing excellent customer support.

Solar Panel Maintenance

  1. Regular Inspections
    • Visual Inspections: Check for physical damage, debris buildup, or shading.
    • Monitoring System: Use monitoring tools to track energy production and detect performance issues.
