Catalina Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Catalina, Arizona
Fixed Tilt Sunlight Hours: 6 hours per day
1-Axis Tilt Sunlight Hours: 8.1 hours per day
2-Axis Tilt Sunlight Hours: 8.5 hours per day
The amount of hours from sunrise to sunset is equal to the total sunlight hours in a 24 hour period. Similarly, peak sun hours are the amount of total sunlight hours in a 24 hour period that are strong enough to provide power from being captured by a solar panel. Not every hour of sunlight delivers the same amount of energy resources. The sunlight at sunrise does not provide as many resources as the amount of sunlight mid-day. Thus, looking at the average peak sunlight hours for Catalina is valuable for calculating your solar needs.
Although you can easily predict sunrise and sunset hours each day to the minute, looking at latitude can help with your solar planning. The closer you get to the equator the closer your latitude gets to zero. Sunlight hours on the equator are consistent throughout the entire year. Places further from the equator can have large variance in daily sunlight. For example higher latitudes can have very long summer days with lots of sunlight and very dark winters. The latitude of Catalina is 32.5.
Throughout the day the sun obviously moves throughout the Catalina sky. The suns position in the sky also changes throughout the year with the seasons. A fixed solar panel does not accommodate for these changes. However, a 1-axis panel rotates and follows the sun’s path during the day. A 2-axis panel both follows the sun’s daily path as well as the seasonal differences
Looking at latitude, average peak sun hours and various data can obviously help when planning for your solar power needs. The one thing you can never fully account for is changing weather. Storms, rain, cloud coverage all have an impact on solar panel capabilities.
The average daily peak sunlight hours in Catalina, Arizona is 6 hours. Use this number when trying to calculate your solar needs in Catalina. As you can see above, if you were to use a 1-Axis or 2-Axis panel then the daily average would increase to 8.1 hour and 8.5 hours, respectively.
