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 Annex, Oregon.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Annex is 44.2. Knowing the latitude of Annex 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.
Since a fixed solar panel is set in one position it is ideal to place it at an angle that will expose the panel to the most sunlight throughout the year. This angle is generally the same angle of your latitude which is 44.2 for Annex. You do not need to strategically place a 1-axis or 2-axis panel as much as you do a fixed panel. A 1-axis panel follows the movement of the sun during the day. Additionally, a 2-axis panel also adjusts for the suns various positions in the sky throughout the year.
There are more variables than latitude that can change average peak sun hours. Weather patterns and geography will influence solar insolation that reaches your system. Thick grey storm clouds for example will block out a lot of the sun to the point where there may be no peak sun hours in the middle of the day when the sun is usually very powerful. Trees and mountains can deflect the sunlight, so be sure your solar panel is selectively placed.
In Annex you can look at the average peak sun hours of a fixed solar panel mount, which will be 5.1 hours. This number iis an estimate based on data of previous years. With a tracking mount in Annex you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 6.8 hours, or a 2-axis mount and potentially increase your average to 7.1 hours.
