Looking at the average peak sunlight hours in Ralston 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 Ralston, Wyoming.

The equator has a latitude of zero while Ralston has a latitude of 44.7. 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 Ralston 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

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 Ralston 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, Ralston will receive 5.9 average peak sun hours per day. This number can be increased to 6.7 hours by using a 1-axis tracking mount, or 6.9 hours from a 2-axis tracking mount.
