Georgia's Solar Potential
The amount of sun shining at the earth's surface is called solar insolation. Insolation values are expressed in kWh/mē per day, or the amount of solar energy measured in kilowatt-hours striking a square meter of the earth's surface.
Several factors such as weather patterns, humidity and haze can affect local insolation levels. However, as can be seen in the map below, insolation values in Georgia are significant enough to support solar energy systems in our state, with the southern two-thirds of Georgia having equivalent solar insolation values to most of the state of Florida.
