Solar Home Lighting System

A solar home system aims at providing solar electricity for operating lights and / or fan or energizing a DC operated portable TV set, Radio, Music System for specified hours of operation per day.

Photovoltaic cells are solid-state semiconductor devices that convert Solar Energy into Electricity (direct current). These Solar cells are connected in series or in parallel to obtain desired output and are called Solar modules.

Solar Home lighting Systems are powered by solar energy using solar cells that convert solar energy (sunlight) directly to electricity. The electricity is stored in batteries and used for the purpose of lighting whenever required. These systems are useful in non-electrified rural areas and as reliable emergency lighting system for important domestic, commercial and industrial applications. The SPV systems have found important application in the dairy industry for and other centers mostly located in rural areas.

The Solar Home Lighting system is a fixed installation designed for domestic application. The system comprises of Solar PV Module (Solar Cells), charge controller, battery and lighting system (lamps & fans). The solar module is installed in the open on roof/terrace – exposed to sunlight and the charge controller and battery are kept inside a protected place in the house. The solar module requires periodic dusting for effective performance.These systems are designed to give a daily working time of 3-4 hours with a fully charged battery. The system provides for buffer storage for 1-2 non-sunny /cloudy days.
