Solar panel warranties can vary depending on the grade or quality of the panels. Generally, solar panels are categorized into three main grades: economy, standard, and premium. Here’s a breakdown of warranty coverage typically associated with each grade:
Economy Grade Solar Panels:
- Warranty Length: Economy-grade solar panels usually come with warranties ranging from 5 to 10 years.
- Performance Guarantee: These panels may have a power output guarantee of around 80% of their rated capacity after 10 years and 70% after 25 years.
- Limited Coverage: Economy-grade warranties typically cover manufacturing defects and premature wear but may have more limited coverage compared to higher-grade panels.
Standard Grade Solar Panels:
- Warranty Length: Standard-grade solar panels commonly offer warranties ranging from 10 to 15 years.
- Performance Guarantee: Performance warranties for standard-grade panels often ensure around 85-90% of rated capacity after 10 years and 80% after 25 years.
- Enhanced Coverage: These panels may have better coverage for manufacturing defects, durability, and performance.
Premium Grade Solar Panels:
- Warranty Length: Premium-grade solar panels come with warranties typically ranging from 15 to 25 years.
- Performance Guarantee: Premium panels usually offer performance guarantees of 90% or higher after 10 years and 80-85% after 25 years.
- Extensive Coverage: Premium-grade warranties tend to offer the most comprehensive coverage, including defects, performance, and durability.
- Additional Features: Some premium panels may also come with additional warranties for specific components like inverters or enhanced service and support.
It’s important to note that these are general trends, and actual warranty terms may vary between manufacturers and specific product lines. When choosing solar panels, it’s essential to consider not only the warranty but also factors like efficiency, durability, and the reputation of the manufacturer. Additionally, warranties are typically backed by the manufacturer, so it’s essential to choose a reputable company with a strong track record in the industry.
