Best Angle for Solar Panels in Arizona Based on Latitude?

Understanding Arizona’s Solar Potential

Arizona’s latitude determines the optimal solar panel tilt angle, with the ideal range being between 30 to 40 degrees. This angle ensures maximum energy production throughout the year, considering the state’s mild winters and hot summers. To calculate the ideal tilt angle, use the latitude formula: tilt angle = latitude - 15 degrees.

Considering Seasonal Variations

In Arizona, the optimal tilt angle is adjusted to account for seasonal variations. During the winter months, the sun’s rays strike the earth at a lower angle, resulting in a higher tilt angle (35-40 degrees) for increased energy production. Conversely, during the summer months, a lower tilt angle (25-30 degrees) helps to reduce overheating and prevent energy losses.

Adjusting for Local Topography

When installing solar panels in Arizona, it’s essential to consider local topography, including terrain and shading. In areas with significant shading, a lower tilt angle may be necessary to minimize energy losses. For installations in mountainous or hilly regions, a steeper tilt angle may be required to compensate for the reduced sunlight exposure. Always consult local experts or conduct thorough site assessments to determine the optimal tilt angle for your specific installation.
