Why is it important to clean solar panels in Arizona?

Arizona is known for its abundant sunshine, making it a prime location for solar energy production. However, the state is also known for its dust and dirt, which can accumulate on the surface of solar panels and reduce their efficiency. According to a study conducted by the National Renewable Energy Laboratory (NREL), dirty solar panels in Arizona can lose up to 30% of their efficiency, which can have a significant impact on the amount of energy they produce.

How often should solar panels be cleaned in Arizona?

In Arizona, solar panels should be cleaned more frequently than in other regions due to the high levels of dust and dirt in the air. It is recommended to clean solar panels at least twice a year in Arizona, and possibly more frequently if there are heavy dust storms or other severe weather conditions, or if a noticeable decrease in production occurs. According to research published in the International Journal of Sustainable Energy, the accumulation of dust particles on the surface of a photovoltaic (PV) panel greatly affects its performance especially in dusty areas, with the study showing a ~34% reduction in the maximum output power of a dusty panel.


Can’t rain clean solar panels in Arizona?

While rain can help to wash away some of the surface debris on solar panels in Arizona, it is often not enough to keep them clean and functioning at their highest efficiency. Think about your vehicle after a rain storm…doesn’t it almost look MORE dirty then before the rain storm? The dirt becomes physically stuck to the surface. Check out this picture (post rain storm). The high levels of dust and dirt in the air can quickly accumulate on the surface of solar panels, and rainwater can actually leave mineral deposits on the surface of the panels, which can reduce their efficiency over time.

Do I need to hire a professional to clean my solar panels in Arizona?

While it is possible to clean solar panels yourself, it is generally recommended to hire a professional in Arizona to ensure that the job is done safely and effectively. Professional solar panel cleaning companies in Arizona have the necessary equipment, including crucial deionized water systems, and expertise to clean solar panels without causing damage, and they can also identify any potential issues with the panels that may need to be addressed. Attempting this cleaning on your own with chemicals, soaps, or water that is not deionized may cause further buildup or even cause panel damage.

What are the benefits of cleaning solar panels in Arizona?

The primary benefit of cleaning solar panels in Arizona is increased efficiency and energy output, which can help to reduce energy costs and increase the return on investment for solar panel systems. Additionally, clean solar panels can last longer and require less maintenance over time. According to a report published in 2019 by the International Energy Agency (IEA), titled “PV Performance and Reliability: Lessons Learned and Best Practices”, the IEA recommended regular maintenance, including cleaning, as a key strategy to improve the reliability and longevity of solar panels. The report emphasizes that proper maintenance, including cleaning, can help to prevent potential defects and issues that can reduce the lifespan of solar panels.

Overall, regular cleaning of solar panels is crucial for maximizing their efficiency and lifespan in Arizona due to the high levels of dust and dirt in the air. According to various studies, dirty solar panels in Arizona can lose up to 30%+ of their efficiency. Hiring a professional solar panel cleaning company in Arizona is recommended to ensure safe and effective cleaning.

Are there any discounts available for routine cleanings?
