The average amount of peak sun hours in a day is a different and more useful number as it relates to solar panels than total sun hours. Total sun hours are exactly what you would expect; the total amount of hours that the sun is out during a 24 hour period. Peak sun hours, on the other hand, are the total number of hours in a day where the sunshine is strong enough to to be absorbed and used by solar panels. Sunlight early in the morning or late at night is often not strong enough to count toward peak sun hours. Because of this, total sun hours will always be more than peak sun hours. Looking at the average peak sun hours in Mount Hood throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Mount Hood is 45.5. Knowing the latitude of Mount Hood 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 Mount Hood 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
Although weather predicting technology has greatly evolved over time, it is still a rather unpredictable factor that will affect the amount of peak sun hours your solar power system will receive. Cloudy days for example will usually have lower peak sun hours that a clear sunny day. And areas that usually have more average sunny days per year will probably have higher peak sun hours that areas that are often overcast or stormy.
Since we know the latitude of Mount Hood we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 4.5 peak sun hours per day. 5 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 6.7 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
