2-Axis Tilt Sunlight Hours: 5.3 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. 4.2 peak sun hours means that in Glen Lyon on average there are 4.2 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.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Glen Lyon is 41.2. Knowing the latitude of Glen Lyon can help you plan for your solar panel setup, as the larger the latitude the more variance you will see throughout the year for total daily sunlight hours.
Throughout the day the sun obviously moves throughout the Glen Lyon 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
Another reason to consider average peak sun hours is because weather can dramatically affect the day-to-day output of solar panels. It goes without saying that a dark stormy day will produce less output than a clear sunny day. Looking at a yearly average helps account for these daily variables.
We can use previous years of data to estimate the amount of peak sun hours in Glen Lyon. A fixed tilt mount for example will receive 4.2 average hours per day. For more efficiency for your system in Glen Lyon you could use a 1-axis tracking mount and increase your daily peak sun average to 5.2 hours, or even further with a 2-axis panel to get an average of 5.3 hours.
