TECHNICAL SPECIFICATION OF SOLAR HOME LIGHT SYSTEM: A solar home lighting system (SHS), converts solar energy into electricity and provides a comfortable level of illumination in one or more rooms of a house. There are several SHS models featuring one, two, or four CFLs (Compact Fluorescent Lamps).

The system could also be used to run a small DC fan or a 12-V DC television along with the CFL (s).
