Mooresville Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Mooresville, Alabama
Fixed Tilt Sunlight Hours: 4.8 hours per day
1-Axis Tilt Sunlight Hours: 6.1 hours per day
2-Axis Tilt Sunlight Hours: 6.3 hours per day
The average amount of peak sun hours in a day is a different and more useful number as it relates to solar panels than total sun hours. Total sun hours are exactly what you would expect; the total amount of hours that the sun is out during a 24 hour period. Peak sun hours, on the other hand, are the total number of hours in a day where the sunshine is strong enough to to be absorbed and used by solar panels. Sunlight early in the morning or late at night is often not strong enough to count toward peak sun hours. Because of this, total sun hours will always be less than peak sun hours. Looking at the average peak sun hours in Mooresville throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
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 Mooresville is 34.6.
Since a fixed solar panel is set in one position it is ideal to place it at an angle that will expose the panel to the most sunlight throughout the year. This angle is generally the same angle of your latitude which is 34.6 for Mooresville. You do not need to strategically place a 1-axis or 2-axis panel as much as you do a fixed panel. A 1-axis panel follows the movement of the sun during the day. Additionally, a 2-axis panel also adjusts for the suns various positions in the sky throughout the year.
The sun is a great ball of gas that rises and sets every day that the earth rotates while in orbit around the sun. Barring any major disasters this is a very predictable occurance every day. Latitude helps predict this even more, narrowing it down to the minute for sunrise and sunset. But some things aren’t as predictable that will greatly influence the efficiency of solar panels. Weather and cloud coverage for example can greatly diminish peak sun hours on any given day. Thick storm clouds will block a high percentage of the sun's rays, resulting in lower output of your solar panels. Weather needs to be factored into deciding when to use your system, or how much output one expects to get.
Since we know the latitude of Mooresville we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 4.8 peak sun hours per day. 6.1 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 6.3 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
