TRANSCRIPT
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
PROSRenewable Energy storage methodsRobustEasily installed and movedSolar lights provide a gentle lightEasy Installation and RepairSaves 90% of electricity
CONSAffected by weather conditionsColor of solar light can be too blue, which
does not compliment the landscape Some less expensive units can be flimsy Solar lights may have a shorter life span than
higher qualityElbow Grease RequiredCannot be used for heavy load
Give your children a brighter tomorrow Save ENERGY switch to Green Lightening
