Solar Green Energy Summary for Westerville, Ohio
Fixed Tilt Sunlight Hours: 4.4 hours per day
1-Axis Tilt Sunlight Hours: 5.3 hours per day
2-Axis Tilt Sunlight Hours: 5.5 hours per day
Peak sun hours is arguably the most important number to consider before installing your solar panels. Unlike total sun hours, peak sun hours are calculated by looking at the amount of sunlight hours in a 24 hour period that is strong enough to be absorb by a solar panel. One way to imagine peak sun hours is to think about a solar powered calculator you owned in school. If you covered the solar panel with your finger, or tried to use the calculator in the dark, the calculator would not work. As you slowly exposed the calculator to light the calculator would eventually turn on and be usable. The same is true with peak sun hours; these are the hours that your solar panels receive enough sunlight to work. Looking at the average peak sunlight hours of 4.4 per day can help you determine the amount of solar panels you need to install to power your home or business in Westerville, Ohio.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Westerville is 40.1. Knowing the latitude of Westerville 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.
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.
Weather is one of the major culprits that will cause inconsistent total peak sun hours for any given day. The sunrise and sunset will always be predictable every day, but the weather is hard to predict and cloud coverage can greatly diminish the efficiency of a solar power system on any given day. On the bright side, a location that is known to have cloudy weather a majority of the year could have unexpectedly more sunny days, so it can go both ways.
We can use previous years of data to estimate the amount of peak sun hours in Westerville. A fixed tilt mount for example will receive 4.4 average hours per day. For more efficiency for your system in Westerville you could use a 1-axis tracking mount and increase your daily peak sun average to 5.3 hours, or even further with a 2-axis panel to get an average of 5.5 hours.
