Solar Panel Warranty
Solar panel warranties are essential for protecting a homeowner's investment in their residential solar energy system. These warranties provide assurance that the solar panels will perform as expected and be free from defects in materials and workmanship for a specified period. Understanding the different types of warranties and their coverage is crucial for making informed decisions when considering solar panel installation.
Key aspects of solar panel warranties include:
- Product warranty: Also known as the materials warranty, this covers defects in the solar panel itself, such as manufacturing flaws or premature wear and tear. Product warranties typically range from 10 to 25 years, with some manufacturers offering even longer coverage.
- Performance warranty: This warranty guarantees that the solar panels will produce a minimum amount of electricity over a specified period, usually 25 to 30 years. The performance warranty ensures that the panels will maintain a certain level of efficiency, often guaranteeing 80-90% of the original output by the end of the warranty term.
- Workmanship warranty: Offered by the solar installer, this warranty covers issues related to the installation process, such as improper wiring or mounting. Workmanship warranties generally span a shorter period, typically 1-10 years, and may vary depending on the installer.
- Inverter warranty: Inverters, which convert the direct current (DC) electricity generated by the solar panels into alternating current (AC) for household use, often have separate warranties. Inverter warranties usually range from 5 to 15 years, depending on the manufacturer and model.
When evaluating solar panel warranties, homeowners should carefully review the terms and conditions, including the length of coverage, exclusions, and claim procedures. It is also essential to choose reputable manufacturers and installers with a proven track record of honoring their warranties and providing reliable customer support.
