Home Lighting System

Compact Fluorescent Lamp (CFL) based Home Lighting System

A solar home lighting system (SHS) provides a comfortable level of illumination in one or more rooms of a house. The SHS consists of a PV module, control electronics, battery, and luminaire(s). There are several SHS models featuring one, two, or four luminaires based on Compact Fluorescent Lamp (CFL). The system could also be used to run a small DC fan or a 12-V DC television along with the CFL.

PV module converts sunlight into electricity, which powers the luminaire(s), which consists of Compact Fluorescent Lamp (CFL) and an Electronic Circuit.

White LED (W-LED) based Home Lighting System

A solar home lighting system (SHS) provides a comfortable level of illumination in one or more rooms of a house. The SHS consists of a PV module, control electronics, battery, and luminaire(s).

PV module converts sunlight into electricity, which powers the luminaire(s). White Light Emitting Diode (W-LED) is a solid state device which emits light when electric current passes through it.

Broad Performance Specifications

The broad performance specifications of a W-LED based Home Lighting system are given below:

PV Module 6-24 Watt peak under STC
