Why solar?

For Zion National Park, sustainability isn’t just a goal, it’s a responsibility. As stewards of one of the country’s most treasured natural landscapes, park leadership was committed to reducing environmental impact while preserving resources for future generations. Solar energy offered a clear path forward. By generating clean, renewable power on-site, Zion can significantly reduce its reliance on traditional energy sources and lower its carbon footprint.

Just as important, the financial benefits of solar align directly with the park’s mission. Every dollar saved on energy costs can be reinvested into maintaining trails, enhancing visitor experiences, and protecting the park’s unique ecosystem. Solar allows Zion National Park to do more with its resources, making it a natural fit for their long-term vision.

For this project, they selected Enphase because it was the right technology to achieve Zion’s goals.  

A longtime Enphase partner and early adopter of the IQ9N-3P Commercial Microinverter, Prometheus had the confidence to select Enphase for this 480 VAC application.
