Commercial Solar Electric Power System Assemblies
The SEPCO™ power assemblies are complete, self contained lighting power units. These independent power supplies use our unique split system design which allows the power assembly to be mounted separately from the light fixture. The power assembly collects the solar energy and stores this energy in a battery. At night, the solar power assembly applies the battery energy to the lighting fixture(s) for the amount of time you have selected when choosing the load controller. The battery in the power assembly holds plenty of energy to operate the fixture through many nights when the weather has been inclement. The LCU1 load computer unit overseas all electronic control functions of the system.
There are 12 different sizes of power assemblies ranging from 10 to 340 Watts. The next page shows there are three types of power assembly structures; small, medium, and large. Some of the features of a SEPCO™ system are shown on the drawing below. For complete system theory of operation, description of assemblies, and specifications of each power assembly, see the SEPCO™ technical manual, SEPCO™ Publication SELSM; Rev. 294.

*Note
The amount of power shown uses 5 hours of full power sun as worst case scenario. Consult your local solar insolation / sun tables or the SEPCO™ factory if you are unsure of how many sun hours there are in your location. The 5 hours that is used is a value consistent with a moderately sunny location. Also note: if your lamp consumption is slightly over one of the power assemblies, and a timer is used, the operating time could be reduced slightly to lower the overall load. |
