Effingham Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Effingham, South Carolina
Fixed Tilt Sunlight Hours: 5.5 hours per day
1-Axis Tilt Sunlight Hours: 6 hours per day
2-Axis Tilt Sunlight Hours: 6.5 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 Effingham is valuable for calculating your solar needs.
The equator has a latitude of zero while Effingham has a latitude of 34.1. 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.
You will notice that the average peak sun hours for Effingham change based on the type of panel being used. The reason for this is quite simple. A fixed panel does exactly what it sounds like, remains fixed in one position at all times. A 1-axis and 2-axis panels have axis that allow them to rotate. The 1-axis rotates with the sun's daily east to west movement while a 2-axis also adjusts for seasonal changes.
Another reason to consider average peak sun hours is because weather can dramatically affect the day-to-day output of solar panels. It goes without saying that a dark stormy day will produce less output than a clear sunny day. Looking at a yearly average helps account for these daily variables.
By taking the latitude of Effingham one can get a close estimate of the amount of average peak sun hours per day for the geographical area. It varies with technology and the type of solar panel mount you use, but for a fixed mount solar panel in Effingham one can expect close to 5.5 average peak sun hours per day. With a 1-axis tracking mount you would get 6 hours per day, and 6.5 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
