Solar Green Energy Summary for Normandy Park, Washington

Lattitude: 47.4344

Sunlight

Fixed Tilt Sunlight Hours: 3.7 hours per day

1-Axis Tilt Sunlight Hours: 4.7 hours per day

2-Axis Tilt Sunlight Hours: 5.1 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. 3.7 peak sun hours means that in Normandy Park on average there are 3.7 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.

If you open the newspaper in the morning or watch the weather channel on the news you can get an accurate prediction of sunrise and sunset each day for Normandy Park. However, still knowing that the latitude of Normandy Park is 47.4 can be a helpful number for your solar panel setup and planning. The closer your latitude is to zero the closer you are to the equator. At the equator you find the most consistent total sunlight hours throughout any given day of the year. As your latitude increases you can see larger discrepancies of daily sunlight hours during the year. For example, having very long summer days and very short and dark winter days

They type of solar panel you use has an affect on the average peak sunlight hours. Some panels allow for movement, so they can track the sun as it rises in the east and sets in the west, or as the seasons change and the sun's path changes. A fixed panel remains fixed and does not have the ability to rotate, whereas a 1-axis and 2-axis panel can adjust with the sun.

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.

Since we know the latitude of Normandy Park we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 3.7 peak sun hours per day. 4.7 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 5.1 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
