How Long Do Solar Panels Last in Snowflake, Arizona?

If you're considering installing solar panels in Snowflake, Arizona, one of the most important questions you might have is how long they last. Solar energy is a long-term investment, and understanding the lifespan of your system can help you determine the return on investment.

The Average Lifespan of Solar Panels

Most high-quality solar panels last between 25 to 30 years. However, this doesn’t mean they suddenly stop working after three decades. Instead, their efficiency gradually decreases over time. Many panels still operate at 80% or more of their original efficiency after 25 years.

What Factors Affect Solar Panel Lifespan?

Several factors can impact how long your solar panels last in Snowflake:

• Quality of the panels – Premium panels from top manufacturers tend to last longer and degrade slower.

• Weather conditions – Snowflake’s sunny climate is ideal, but occasional storms or hail can affect panel longevity. Fortunately, most solar panels are designed to withstand high winds and hail up to 1 inch in diameter.

• Maintenance – Regular cleaning and maintenance help prevent dirt buildup and keep panels performing efficiently.

• Installation quality – A properly installed system lasts longer and operates more effectively.

  
  

Do Solar Panels Degrade Over Time?

Yes, solar panels lose efficiency gradually. The average degradation rate is about 0.5% per year, meaning after 25 years, your panels may still operate at around 87.5% efficiency. The National Renewable Energy Laboratory (NREL) provides more information on solar panel degradation here: https://www.nrel.gov/pv/lifetime.html.

How to Extend the Life of Your Solar Panels

To ensure your solar panels last as long as possible, follow these tips:

• Keep them clean – Snow, dust, and debris can reduce energy production. Occasional cleaning helps maximize efficiency.

• Monitor performance – Many solar systems come with monitoring software to track energy production and detect issues early.

• Work with a trusted installer – Choosing a reputable solar company ensures proper installation and long-term support.

  
  

Are Solar Panels a Good Long-Term Investment in Snowflake AZ?

Even after 25 or more years, your panels will still generate significant electricity. Plus, with Arizona’s high electricity rates and strong sunlight, the savings over time make solar a smart financial decision.
