It is important to remember, if you are looking to install solar panels then you have to understand that not every hour of sunlight will be converted at the same efficiency ratio. Certain factors such as time of year, the angle of both the sun and panels, varied cloud coverage, tracking mounts, or if you are using the system year round are just a few of the factors that could affect efficiency ratios.

Because of this you should look at average of peak hours of sunlight per day, which are the most ideal sunlight hours of solar insolation.

Tennessee receives an average of 4.45 peak sun hours a day on a fixed solar panel.
