Catalina Foothills Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Catalina Foothills, Arizona
Fixed Tilt Sunlight Hours: 6.2 hours per day
1-Axis Tilt Sunlight Hours: 8.8 hours per day
2-Axis Tilt Sunlight Hours: 8.8 hours per day
It goes without saying that throughout the year the amount of sunlight in any given day is going to vary. The time of year and weather will have a strong influence on daily sunshine. Looking at the average amount of peak sunshine hours in a day during an entire year stretch is a valuable exercise when trying to determine the amount and type of solar panels you need to install to power your business or your home. 6.2 peak sun hours means that in Catalina Foothills on average there are 6.2 hours a day where the sun is strong enough for solar panels to harness its energy. This number is less than the amount of total sunlight hours in a day because there are times during the day (ex. sunrise and sunset) where the sun is not strong enough to benefit solar panels.
The equator has a latitude of zero while Catalina Foothills has a latitude of 32.3. Any city located on the equator will receive the most sunlight throughout the year because the sunlight arrives at a perpendicular 90 degree angle to the earth at the equator. The further you are from the equator the more your daily sunlight hours can vary.
Throughout the day the sun obviously moves throughout the Catalina Foothills 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
Peak sun hours are greatly affected by weather patterns. Cloud coverage is a huge factor in peak sun hours per day because heavy cloud coverage will diminish the power of the solar insolation. You can use historical climate data to estimate average cloud and weather coverage, but it will obviously vary slightly from year to year.
We can use previous years of data to estimate the amount of peak sun hours in Catalina Foothills. A fixed tilt mount for example will receive 6.2 average hours per day. For more efficiency for your system in Catalina Foothills you could use a 1-axis tracking mount and increase your daily peak sun average to 8.8 hours, or even further with a 2-axis panel to get an average of 8.8 hours.
