Great Question!
The lifespan of a solar panel used for home installations in Arizona typically ranges from 25 to 30 years or more. Most reputable solar panel manufacturers offer warranties that guarantee the performance of solar panels for 25 years or longer.
Several factors contribute to the longevity of solar panels:
- Quality of Materials: High-quality solar panels made with durable materials tend to have longer lifespans. Look for panels from reputable manufacturers with a track record of reliability.
- Maintenance: Proper maintenance, such as regular cleaning to remove dust and debris, can help extend the lifespan of solar panels. In Arizona, where there can be a buildup of dust due to the arid climate, periodic cleaning may be especially important.
- Environmental Conditions: Arizona’s climate, with its high temperatures and intense sunlight, can impact the performance and longevity of solar panels. However, most modern solar panels are designed to withstand these conditions, and reputable manufacturers test their panels to ensure durability in various environments.
- Degradation Rate: Solar panels degrade over time, meaning their efficiency gradually decreases. The degradation rate varies depending on the quality of the panels but is typically around 0.5% to 1% per year for most modern panels. This means that even after 25 years, solar panels should still retain a significant portion of their original efficiency.
Overall, with proper maintenance and under normal operating conditions, solar panels installed for home use in Arizona can be expected to generate electricity reliably for 25 to 30 years or more.
We look forward to installing yours!
