Watertown Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Watertown, Ohio
Fixed Tilt Sunlight Hours: 4.3 hours per day
1-Axis Tilt Sunlight Hours: 5.3 hours per day
2-Axis Tilt Sunlight Hours: 5.6 hours per day
Peak sun hours are a vital measurement to understand when considering the installation of solar panels. Peak sun hours are not the same as total sunlight hours because not every hour of sunlight during the day has enough strength and solar insolation to qualify as a peak sun hour. The rule of thumb is that a peak sun hour is when the intensity of the sun that is hitting your solar panel is providing at least 1,000 watts per square meter. This is an arbitrary number, but it is a number where most solar panels will be producing an efficient output and not underperforming due to sunshine that is not strong enough or direct enough.
The equator has a latitude of zero while Watertown has a latitude of 39.5. Any city located on the equator will receive the most sunlight throughout the year because the sunlight arrives at a perpendicular 90 degree angle to the earth at the equator. The further you are from the equator the more your daily sunlight hours can vary.
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 39.5 for Watertown. 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.
Looking at latitude, average peak sun hours and various data can obviously help when planning for your solar power needs. The one thing you can never fully account for is changing weather. Storms, rain, cloud coverage all have an impact on solar panel capabilities.
The average daily peak sunlight hours in Watertown, Ohio is 4.3 hours. Use this number when trying to calculate your solar needs in Watertown. As you can see above, if you were to use a 1-Axis or 2-Axis panel then the daily average would increase to 5.3 hour and 5.6 hours, respectively.
