Looking at the average peak sunlight hours in Chehalis is a valuable number for determining your solar power setup. Peak sunlight hours are only the hours a day in which the sunlight is strong enough for the solar panels to do their job. Not every hour of sunlight was created equal. For example, solar panels do not provide much use during early sunrise and sunset, and therefore you should not look at total hours of sunlight in a day, but instead focus on peak sunlight hours. Using this number will provide a much better estimate of your needs for setting up panels in Chehalis, Washington.

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 Chehalis. However, still knowing that the latitude of Chehalis is 46.7 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

There are a few ways to increase average peak sun hours per year for your solar power system. One way is to use a tracking mount solar panel instead of a fixed tilt solar panel. A 1-axis mount will track the sun throughout the sky from sunrise to sunset, giving your panel a more efficient facing direction towards the sun throughout the day. A 2-axis solar panel will track the sun in the sky throughout the day, but also change and follow the angle of the sun in the sky throughout the year. Both of these axis system solar panels will produce higher average peak sun hours than a fixed solar panel.

The sunrise and sunset is very predictable every day, but things like cloud coverage and weather are less predictable and vary daily and annually. If a location that is usually very sunny experiences a huge increase in storms and cloud coverage in a given year than the average peak sun hours for that day or year will probably decrease. Tall objects such as trees and buildings can block out the sun during high solar insolation times, so be sure to strategically place your solar panels to get better efficiency.

We can take the latitude of Chehalis and use that number to know the amount of total sunlight hours in the region from sunlight to sunset and estimate that with a fixed solar panel, Chehalis will receive 3.6 average peak sun hours per day. This number can be increased to 5 hours by using a 1-axis tracking mount, or 6 hours from a 2-axis tracking mount.
