It's the current theoretical maximum solar radiation value at the current date and time at your location. It is calculated using the Ryan-Stolzenbach formula, and uses the 'transmission factor' configurable in the station settings to allow for the effect of transmission through the atmosphere. The figure is not particularly useful in itself; it is used if you have a solar sensor, to compare with the current solar radiation reading, in an attempt to determine whether the sun is currently shining or not. | It's the current theoretical maximum solar radiation value at the current date and time at your location.
