Solar
Energy Techonologies - Solar Home Light System
Introduction
Home lighting System 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 lighting milk collection/ chilling
centres 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 schematic of the HLS is given below.
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.
Operation Time
The above 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.
