When trying to calculate your solar power needs there are a variety of factors to consider. Panel type and location, electricity needs, number of panels needed etc. One key to figuring out the math is factoring in the average peak sunlight hours in a day. Unlike total sunlight hours, peak sunlight hours are only when the sun is strong enough to power your solar panel. Using this number can help determine your needs to power your home or business in Warrenton, Oregon.

The equator has a latitude of zero while Warrenton has a latitude of 46.2. 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 Warrenton 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.

In Warrenton you can look at the average peak sun hours of a fixed solar panel mount, which will be 3.8 hours. This number iis an estimate based on data of previous years. With a tracking mount in Warrenton you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 4.5 hours, or a 2-axis mount and potentially increase your average to 6.7 hours.
