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 2

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).


A Solar lantern is a simple application of solar photovoltaic technology, which has found good acceptance in rural regions where the power supply is irregular and scarce. Even in the urban areas people prefer a solar lantern as an alternative during power cuts because of its simple mechanism. A solar Lantern is made of three main components - the solar PV panel, the storage battery and the lamp. The operation is very simple. The solar energy is converted to electrical energy by the SPV panel and stored in a sealed maintenance-free battery for later use during the night hours. A single charge can operate the lamp for about 4-5 hours.


This system is designed for outdoor application in un-electrified remote rural areas. This system is an ideal application for campus and village street lighting. The system is provided with battery storage backup sufficient to operate the light for 10-11 hours daily. 3

The system is provided with automatic ON/OFF time switch for dusk to down operation and overcharge / deep discharge prevention cut-off with LED indicators. The solar street light system comprise of 74 Wp Solar PV Module 12 V, 75 Ah Tubular plate battery with battery box Charge Controller cum inverter (20-35 kHz) 11 Watt CFL Lamp with fixtures 4 metre mild steel lamp post above ground level with weather proof paint and

mounting hardware. The SPV modules are reported to have a service life of 15-20 years. Tubular

Batteries provided with the solar street lighting system require lower maintenance; have longer life and give better performance as compared to pasted plate batteries used earlier. The systems electronic provide for over-charge and over-discharge cut-off essential for preventing battery and luminaries damages.


An LED street light (also called LED road lighting) is an integrated LED (Light Emitting Diode) light fixture that is used as street lighting. Because they are more energy efficient than other technologies used for street lighting, LED street lights can save on the cost of keeping streets well lit during the night. 4

An LED street light is an integrated light that uses LEDs as its light source. These are considered integrated lights because the luminaries and the fixture are not separate parts. In manufacturing, the LED light cluster is sealed on a panel and then assembled to the LED panel with a heat sink to become an integrated lighting fixture. A light-emitting-diode lamp is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. Since the light output of individual light-emitting diodes is small compared to incandescent and compact fluorescent lamps, multiple diodes are used together. LED lamps can be made interchangeable with other types. Most LED lamps must also include internal circuits to operate from standard AC voltage. LED lamps offer long life and high efficiency, but initial costs are higher than that of fluorescent lamps.

Solar Photovoltaic industry in India

Begun as far back as in the mid 70s solar photovoltaic programme of the Government of India is one of the largest in the World. While the rest of the world has progressed tremendously in production of basic silicon monocrystalline photolytic cells, in India the major players are Central Electronics Ltd, BHEL, REIL and the other manufacturers of SPV modules are in fact assemblers sourcing the cells and carrying out assembly. Where this segment of basic manufacturing has not shown much growth in India and is unlikely also in the near future due to high costs involved in manufacturing monocrystalline silicon cells from scratch, the market is growing for SPV applications based products with the active encouragement of the government.


Electricity and social development go hand in hand. Rural areas of India are so farflung that in some cases it is decided not to lay down conventional electricity lines due to the small populace to be served and high cost of laying lines. Conventional gensets are also not feasible due to recurring maintenance problems. The best solution under the circumstances is solar photovoltaic based systems to generate power, run irrigation pumping sets and home lighting and streetlights. In addition to offering subsidy on these products government is also offering training on PV technology, PV system designs and related fields. The programme of MNES comprises of promoting use of PV technology to provide lighting in villages in the form of : TABLE 1.1

Community lighting systems Portable solar lanterns

Capacity usually 1KW to 2.5 KW Small 10Wp SPV module connected to a 12V7AH battery lighting 7 W CFL lamp for 3 hours a day

Street lights

Built around a 75Wp SPV module charging a 100-130AH battery to run a 11W CFL lamp for dusk to dawn operation.

powering two CFLs each of 9 or 11W to work 4-5 hours per day. Some systems also incorporate facility to run a small TV set or a fan from the power supply. Water Pumping Typically 1KW DC motor based

pumping for shallow pumping.



In today's world, the gradual depletion of energy and the gradual deterioration of environment has become a great challenge to us. LED is the most preferred green lighting source in the 21st century, which is the criterion of energy saving and environment protection. Most of the countries in the world have used the policy and rules to map out the spread plan and a revolution in the field of lighting industry is expected soon. In the past three years, we have invested tremendous amount of manpower and resources. Committed to develop new generation semiconductor LED lighting products. LED lamps need only 20% power as that of traditional bulbs and can generate 80 lm/w. These lamps have super long life up to 50,000 hours and 8 times the brightness than traditional light bulb. Now all this is no longer inconceivable, it has it has become a reality.



The fundamental purpose of a Practice School is to prepare for employment in the chosen discipline at the conclusion of undergraduate studies. Study at university is enhanced by the opportunity to relate academic and professional aspects of engineering disciplines. 1. To gain first-hand experience of working as an engineering professional,

including the technical application of engineering methods. 2. 3. 4. To work with other engineering professionals. To experience the discipline of working in a professional organization. To develop technical, interpersonal and communication skills, both oral and
