Greenhills Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Greenhills, Ohio
Fixed Tilt Sunlight Hours: 4.4 hours per day
1-Axis Tilt Sunlight Hours: 5.5 hours per day
2-Axis Tilt Sunlight Hours: 5.4 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 Greenhills throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.
Knowing that the latitude of Greenhills is 39.3 can be helpful for understanding total sunlight hour variance. As you approach the equator latitude approaches zero. The closer the latitude is to zero, the more consistent the daily sunlight hours are throughout the year. Total sunlight hour consistency simply makes planning for your solar power needs easier, but it is certainly not a requirement.
You will notice the difference in peak sunlight hours depending on the panel type. The more flexibility the solar panel has the efficient it can be throughout the day and the year. A fixed solar panel remains in the same position at all times. A 1-axis panel follows the sun throughout the day as it moves through the sky and eventually sets. A 2-axis panel not only tracks the daily movement, but also adjusts based on the sun's changing position in the sky throughout the year as the seasons change.
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.
In Greenhills you can look at the average peak sun hours of a fixed solar panel mount, which will be 4.4 hours. This number iis an estimate based on data of previous years. With a tracking mount in Greenhills you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 5.5 hours, or a 2-axis mount and potentially increase your average to 5.4 hours.
