Slide4 : Solar Powered LED Lighting


Slide5 : Under the PV program of MNES, about 6,10,000 systems aggregating to over 20 MW have been installed. This includes 3,85,000 solar lanterns 1,80,000 home lighting systems 41,000 street lighting systems 4204 water pumping systems and of about 1.2 MWp aggregate capacity of stand alone power plants/packs. SOLAR LIGHTING IN INDIA


Slide6 : ISSUES WITH THE PRESENT SOLAR LIGHTING SYSTEMS They use florescent lightening (tube lights big or compact ones (CFL) lights ) which consumes less electricity than the filament based incandescent (normal) bulbs but still is considerable. To electrify a small hamlet populated by 100 residents, it can cost approximately 5 Lakhs rupees without subsidy. Since there are many storage batteries required the maintenance and their replacement cost is very heavy. The bulbs/ lights fail once in 6 months or so and require maintenance thus complicating the usage in a small inaccessible village. Battery storage and periodic maintenance are the main factor for the dysfunction of many of the installed systems.


Slide7 : White LEDs, A Revolutionary Concept In Lighting TECHNICAL FEATURES OF LEDs : White LEDs are 'Light Emitting Diodes', a type of semiconductor. They are the newest item in today's lighting technology. Unlike other light sources, these WHITE LEDs can take a lot of punishment from vibration, heat and severe cold. WHITE LEDs can be made waterproof, and put into a lighting package with 2 to 1000 WHITE LEDs. They can be used for street lights, sign lighting, spot lighting or anything else. WHITE LEDs need 3.6VDC and use approximately 30 milliamps of current, a power dissipation of 110 milliwatts. The positive power is applied to one side of the LED semiconductor through a lead and a whisker. The other side of the semiconductor is attached to the top of the anvil that is the negative power lead. It is the chemical makeup of the LED semiconductor that determines the color of the light that the LED produces. The plastic housing has three functions: it is designed to allow the most light to escape from the semiconductor; it focuses the light, and it protects the semiconductor from the elements.

Luminosity: White LEDs, typically 20 to 60 Lumens/Watt or between 5000 & 12000 millicandela THRIVE has implemented LED Lighting through Solar Power in a village by name Choututla Tanda in the Panchayat of Yalamalamanda, Chandampet mandal, Nalgonda district. This villiage is nearly 30 KM from the major block head quarters, DEVERAKONDA. This is located in hills and there is no transportation system to the village and one has to reach the villiage by a two wheeler or good four wheel drive vehicle. This village has a population of nearly 142, residing in 30 households. These houses were constructed by the state government 10 years ago. Only two 40 amps 12 volts batteries were used for the village Each battery is charged though a single 37 watt solar panel and usually charged in a single sunny day. 3 to 4 LED bulbs were used in each house. Around 7 lights were used for street lighting. Since the consumption of electricity is very less there is no need to switch them of in the late night. Day lighting automatic switch is used, and the system switches on and off automatically in the day and night times. The battery requires just topping with water once every month. Total cost of the project Rs. 40,000 THRIVE  (Volunteers for Rural Health, Education & Information Technology ) Chintapalli, Nalgonda district Andhra Pradesh - INDIA Phone: +91-8691-233601/2, +91-98663-05772 Email: ranga@thethrive.org www.thethrive.org


Slide9 : White LEDs can be placed in abusive environments White LEDs can be "AC" or "DC" powered depending on the model. White LEDs are the newest lighting device on the market today. White LEDs do not produce "RF" to interfere with radio equipment. White LEDs are a proven technology. White LEDs last about 100, 000 hours of continuous use. White LEDs radiate light at a 15 to 45 degree angle depending on the model. White LEDs can be made completely waterproof for use in many marine applications. White LEDs are polarity protected, so it is hard to make an installation mistake. Some Basic Facts About White LEDs LED Unit > Luminosity: White LEDs, typically 20 to 60 Lumens/Watt or between 5000 & 12000 millicandela

Slide11 : Only two 40 amps 12 volts batteries were used for the villiage Each battery is charged though a single 37 watt solar panel and usually charged in a single sunny day. 3 to 4 LED bulbs were used in each house. Around 7 lights were used for street lighting. Since the consumption of electricity is very less there is no need to switch them of in the late night. Day lighting automatic switch is used, and the system switches on and off automatically in the day and night times. The battery requires just topping with water once every month. The Lighting System


Slide12 : The total cost of Implementation of this system was surprisingly less than Rs. 50000 INR for the entire village and approximately 5 Rs a month for each household to replace the battery after 3 years. The COST involved in providing conventional electricity for lighting to this village would exceed well over Rupees 10Lakhs INR and needs minimum 1 Lakh Rupees for Line losses and maintenance every year. The user has to pay for lighting and replace bulbs frequently and has to bear with limited supply from the grid. Whereas, The total time for Implementation of this system was just 1 week, with installation taking just 1 Day. The TIME involved in providing conventional electricity for lighting to this village would exceed well over an year Whereas,


Slide13 : Community Radio


Slide14 : Community radio is very inexpensive and it is owned by the community(it may cost any where from 10,000 Rs to 1,00,000 Rs) The signal is broadcast in FM mode and it generally reaches upto 20 Km depending on the topography of the area. A user can reach the services with a very inexpensive radio costing 30 Rs. to 100 Rs. any where in the coverage area. Any type of service can be broadcast like, weather, pest information, visits of the officers, scientists, workshops, Camps, marriages, deaths call for the doctor and emergency services, Mandi prices and availability and workload, local music, interviews with local officers. (even missing cattle information) Government NOW PERMITS campus wide radio broadcast for educational and training institutes. Community radio


Slide15 : Vertical Axis Wind Turbine


Slide16 : 70 of the population of the state of Andhra Pradesh are dependent on agriculture for their livelihood. Though there are major surface water projects and big dams, most of the Telenagana districts and some areas in costal and Rayalaseema are dependent on the ground water for agriculture operations. At present there are more than 20 Lakhs pump sets in Andhra Pradesh and usually they are of 5 horse power category. As the ground water level lowers every year, farmers have gone for submersible pump sets. GOAP charges a flat rate on each pump set irrespective of the consumption. However the supply to the agriculture pump sets is limited to less than 8 hrs. With the increasing cost of power and depleting ground water resources, it is becoming increasingly difficult to subsidize/finance the agriculture pump sets.   An alternative model based on turbine systems which address the inadequacies of the existing system has been developed in collaboration with MS AITKIN Australia CONSULTANTS and THRIVE organisation, Chintapally at a cost of Rs. 80,000. At present the utilization of wind turbines for water pumping is quite limited and restricted few NGOs and model farms. The available models generally supply low volume of water for domestic consumption only. Generally the fan type wind pumps are employed and all of them are imported from Netherlands and other countries. Fan type wind mills have complicated rudder mechanism and a system of gears. Maintenance of the system is not available with the local people and consequently they are non functional in most of the places they are installed. WIND TURBINE FOR WATER PUMPING


Slide17 : It has all the advantages of renewable sources of energy and causes no pollution etc. It can pump upto 2 inch water based on the ground water availability and wind speed It needs hardly any maintenance as there are no gears and rudder and related complexities It can operate at very low wind speeds of 6 KM per hour It can be mounted next to the bore well thus facilitating reboring or deepening the existing borewell. It is all likely that it can run for more than 7 hours a day. This model at present has been successfully pumping the water and is undergoing some tests and small modifications so that a mass scale replication is possible. Features:- Click for Video


Slide18 : Activities


Slide19 : India is a agriculture dependent country with a huge variation in topography and climate. Agriculture planning, monitoring and support needs accurate weather data for higher level agencies down to a farmer. At present weather monitoring, forecast in India is very inadequate in terms of coverage, quality and its application for day to day use by the ultimate beneficiary. The main reason for it being the centralized system (Hyderabad or Bombay) , lack of weather conscious field staff, low quality crude manual equipment and others. Weather monitoring station
