Solar Green Energy Summary for Grand Isle, Louisiana

Sunlight

Fixed Tilt Sunlight Hours: 4.5 hours per day

1-Axis Tilt Sunlight Hours: 6.3 hours per day

2-Axis Tilt Sunlight Hours: 6.4 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 Grand Isle is valuable for calculating your solar needs.

Although you can easily predict sunrise and sunset hours each day to the minute, looking at latitude can help with your solar planning. The closer you get to the equator the closer your latitude gets to zero. Sunlight hours on the equator are consistent throughout the entire year. Places further from the equator can have large variance in daily sunlight. For example higher latitudes can have very long summer days with lots of sunlight and very dark winters. The latitude of Grand Isle is 29.2.

You will notice that the average peak sun hours for Grand Isle 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.

In Grand Isle the average yearly peak sun hours for a fixed tilt non-tracking solar panel mount is 4.5. This is for a fixed panel mounted at an angle that is equal to the latitude of the location for the entire year. The amount of peak sun hours increases to 6.3 hours if you are using a 1-axis panel, and to 6.4 hours if you upgrade to a 2-axis solar panel.
