Solar DC Lightings
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). The SHS consists of a PV module of 18 or 37 or 74 Wp capacity, a lead-acid battery (of 12 V and 20 or 40 or 75 AH capacity respectively) and CFLs of 9 W or 11 W rating. The system is designed to work for three to four hours daily, with an autonomy of three days i.e. the system can function for three consecutive cloudy days.
