Solar Green Energy Summary for Eckerman, Michigan
Lattitude: 46.3653
Sunlight
Fixed Tilt Sunlight Hours: 4.2 hours per day
1-Axis Tilt Sunlight Hours: 5.5 hours per day
2-Axis Tilt Sunlight Hours: 5.7 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 Eckerman is valuable for calculating your solar needs.
The latitude at the equator of the earth is zero degrees. This is where sunlight strikes the earth most directly. Due to the earth's curved shape, sunlight hits at a various angles depending on location. As latitude increases, the further you are located from the equator and more variance you see in sunlight hours. The latitude of Eckerman is 46.4.
You will notice that the average peak sun hours for Eckerman 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.
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.
We can use previous years of data to estimate the amount of peak sun hours in Eckerman. A fixed tilt mount for example will receive 4.2 average hours per day. For more efficiency for your system in Eckerman you could use a 1-axis tracking mount and increase your daily peak sun average to 5.5 hours, or even further with a 2-axis panel to get an average of 5.7 hours.
