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 Prattville 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 Prattville is 32.5. Knowing the latitude of Prattville 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.

A tracking mount will increase the average peak sun hours for a solar power system. Think about a panel that is tracking the sun in the sky vs a panel that is fixed and not moving: you will see a higher efficiency ratio of productions. A 1-axis mount will track the sun from East to West from sunrise to sunset and move on a single axis of rotation. A 2-axis mount will track the Sun from East to West the same as a 1-axis mount would, but it will also track the angle of the sun in the sky as it slowly varies season to season. A 2-axis mount is more necessary in high latitude regions where the angle of the sun in the sky changes dramatically between each equinox.

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.

We can take the latitude of Prattville and use that number to know the amount of total sunlight hours in the region from sunlight to sunset and estimate that with a fixed solar panel, Prattville will receive 5.1 average peak sun hours per day. This number can be increased to 6.3 hours by using a 1-axis tracking mount, or 6.4 hours from a 2-axis tracking mount.

A 10kW solar system consists of 31 to 40 solar panels. As they're 1.6m x 1m in size, you'll need quite a lot of roof space to support it – 50 to 65 square metres to be exact.
