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 more than peak sun hours. Looking at the average peak sun hours in Freeburg throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Freeburg is 38.4. Knowing the latitude of Freeburg 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.

Throughout the day the sun obviously moves throughout the Freeburg sky. The suns position in the sky also changes throughout the year with the seasons. A fixed solar panel does not accommodate for these changes. However, a 1-axis panel rotates and follows the sun’s path during the day. A 2-axis panel both follows the sun’s daily path as well as the seasonal differences

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.

Since we know the latitude of Freeburg we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 4.7 peak sun hours per day. 5.6 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 6.3 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.

Well, technically EVs don't emit CO2 but there is CO2 emitted during the process of creating the electricity used to “charge up” the batteries. There is an online tool helps people calculate their greenhouse gas emissions (GHGs) from flying, driving and home energy use.
