If you put your solar powered math calculator in your backpack it will turn off from the lack of sunlight needed to power the device. As you slowly open your backpack and begin to let sunlight in, the calculator will eventually turn on when the amount of sunlight is enough to power the calculator. Similarly, peak sun hours refer to the hours of they day where the sunlight is strong enough to power a solar panel. This is different from total sunlight hours, which is simply the amount of hours in a day when there is any sunlight.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Chester is 48.5. Knowing the latitude of Chester 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.
Throughout the day the sun obviously moves throughout the Chester 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
Although weather predicting technology has greatly evolved over time, it is still a rather unpredictable factor that will affect the amount of peak sun hours your solar power system will receive. Cloudy days for example will usually have lower peak sun hours that a clear sunny day. And areas that usually have more average sunny days per year will probably have higher peak sun hours that areas that are often overcast or stormy.
In Chester you can look at the average peak sun hours of a fixed solar panel mount, which will be 4.7 hours. This number iis an estimate based on data of previous years. With a tracking mount in Chester you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 6.4 hours, or a 2-axis mount and potentially increase your average to 6.7 hours.
