1-Axis Tilt Sunlight Hours: 6.3 hours per day
2-Axis Tilt Sunlight Hours: 6.6 hours per day
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 Sullivans Island 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 Sullivans Island is 32.8. Knowing the latitude of Sullivans Island 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.
There are more variables than latitude that can change average peak sun hours. Weather patterns and geography will influence solar insolation that reaches your system. Thick grey storm clouds for example will block out a lot of the sun to the point where there may be no peak sun hours in the middle of the day when the sun is usually very powerful. Trees and mountains can deflect the sunlight, so be sure your solar panel is selectively placed.
For Sullivans Island the number of average daily peak sunlight hours for a fixed solar panel is 5.3 hours. If you are using a more efficient 1 or 2-axis panel then the number will increase to 6.3 hours for a 1-axis panel and 6.6 hours for a 2-axis panel.
