The amount of hours from sunrise to sunset is equal to the total sunlight hours in a 24 hour period. Similarly, peak sun hours are the amount of total sunlight hours in a 24 hour period that are strong enough to provide power from being captured by a solar panel. Not every hour of sunlight delivers the same amount of energy resources. The sunlight at sunrise does not provide as many resources as the amount of sunlight mid-day. Thus, looking at the average peak sunlight hours for Greenlawn is valuable for calculating your solar needs.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Greenlawn is 40.9. Knowing the latitude of Greenlawn 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.
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.
Climate in your geographical region is a major factor that will influence average peak sun hours per year. If you live in a region that does not have a lot of completely sunny days, then cloud coverage will greatly influence solar insolation on any given day. Mountains and trees may also contribute to lower solar insolation if they block the sun from your panels at any given point of the day.
In Greenlawn you can look at the average peak sun hours of a fixed solar panel mount, which will be 4.8 hours. This number iis an estimate based on data of previous years. With a tracking mount in Greenlawn you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 5.4 hours, or a 2-axis mount and potentially increase your average to 5.5 hours.
