solar home lighting system description A

solar home lighting system

description • A distributed energy access model • High efficiency electronics • Can be assembled and customized by both large and small local entrepreneurs • Utilization of solar photovoltaic (PV) modules to provide electricity for lighting, water pumping, communications, computing, entertainment, and small business appliances • Can be used for domestic and industrial purpose but 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 • This solar module requires periodic dusting • These systems come in different models of varying capacities and specifications and features

components • PV module (photovoltaic module) or Solar cells • Battery • Charge controller • Bulbs • Fans

Working principle • PV technologies use both direct and scattered sunlight to create electricity • connect them to an electric distribution system , or they can stand alone • Generally a lead-acid battery, or alternatively a Ni -HM battery, a Ni-Cd battery or a lithium battery are used to store the electric energy • The DC energy generated by the solar power generation system will have to be converted into AC energy. That is why a DC-AC inverter is needed

Uses • These systems are useful in non-electrified rural areas and as reliable emergency lighting system for important domestic, commercial and industrial applications • Used as lightening system • Also used for cooking purpose • For running fans

pros and cons PROS q. Renewable Energy storage methods q. Robust q. Easily installed and moved q. Solar lights provide a gentle light q. Easy Installation and Repair q. Saves 90% of electricity

CONS q. Affected by weather conditions q. Color of solar light can be too blue, which does not compliment the landscape q. Some less expensive units can be flimsy q Solar lights may have a shorter life span than higher quality q. Elbow Grease Required q. Cannot be used for heavy load
