An apparatus and method provides for managing solar power to a LED illumination device such as a street sign so that the power from a power storage device is monitored and variations in applied power to the LED device can be dynamically made to preserve power or increase power as appropriate. A controller may control the power management based on preprogrammed time periods, environmental factors, and solar availability. Historical tracking of available power may provide a basis for computing available power.
