  • 1. INTRODUCTION Renewable Energy (RE) is now making a noticeable impact especially in the lives ofrural masses. Simultaneously though, its use for urban and semi-urban applications is alsogrowing by the day. The Indian RE programmed was amongst the first few such programmed toshape up globally. Since then, it has assumed respectable market leadership position in a fewareas in wind energy and solar energy. Solar energy is more predictable and dependable thanany other available renewable source of energy. India has significant sun shine for over 300days per year which is approximately 3000hrs of sunshine every year. But only 0.2% of totalenergy production is contributed by the installed capacity. Solar Energy products like solarpanels are now widely being used in India and other parts of the world. Solar lights were not new to rural India. Almost every year, in the month of March, theIndian government installed solar-powered street lights to utilize funds devoted to non-conventional energy. Howerever, in the absence of an organization to assume responsibility, verylittle effort was subcequently put it for proper maintainence of these lights. March was followedby the Indian summer, when abundant sunshine often resulted in the overheating of lightsstopped functioning, thereby creating a perception among villages that solar lights were fragileand unlikely to function for more than three to four months. In 1982 high power usage solarpannels cost was rs 1200/watt but today it is rs 200/watt. A solar electric cell is generally a silicon waffer, a solar array contains of solar photo voltalic(SPV) modules and they charge the batteries, while simultaneously meeting the demands of the loadwhen sufficient sunshine is available. In India Monocrystalline Solar cells, connected suitable tomeet the voltage requierments. But Silicon is expensive and short in supply. The price of Silicon hasincreased upto 50% in the past 3 years. As Silicon is very expensive and scarce looking forsubstitutes for Silicon would be really encourageable. Substitutes availabe are:Copper Indium gallium selenide and Cadmium Telluride.Innovation: The name of our Company is RANSS Pvt. Ltd. Our main innovation is byusing the thin plates we can produce the electricity even in the shaded region. Even there is nohigh sun light, i.e, on a cloudy day, we can produce electricity throughout the year which is themain challenge in the yesters years. By using these thin plates we can cut the manufacturingcost around 40% which is more economical so that rural people with a minimun living standardscan also afford to purchase. Even our proposal is to use invertor for a storage as per thecustomer usuage and preferences.Oppurtunities: In the present senario the three basic challenges are:  The poor people cannot afford technology.
  • 2. 0 The poor people cannot maintain technology. 0h It is not possible to run a commercial venture that fulfills a social objectives. With the introduction of Copper Indium gallium selenide and Cadmium Telluride into the manufacturing of Solar panels would cut –down the manufacturing cost to a greater extent, allowing the poor to afford technology. Facilitating the customers with timely maintaince of the equipment would help them in maintaining the technology. Government is providing subsidies on manufacturing of Solar panels and loans to rural India to purchase these plates. The yester years challenges are todays oppurtunities.Competitors: 0o General Electrics(GE) 0e SunTech Energy Limited. 0u Solartech Energy Systems Ltd. 0o Maharishi Energy Ltd.Edge Over Competitors: Apart from GE we are the only company coming up with substitutes for CrystallineSilicon with Copper Indium gallium selenide which is cost effective over traditional plates,reduces the weight of the Solar panel and these thin film Solar panels would be flexible and easyto use, eleminating the need for mounting structure for a solar array. The most intresting featureof these thin film Solar panels is, they do not require direct sunlight for operation. They can evenwork under shade. So we need not remove trees in the surroundings and there is no problem eventhough it is surrounded by the taller buildings.PRODUCT DESCRIPTION: The Solar Photovoltalic(SPV) power source and non conventional energy source deployedfor powering unelectrified villages essentially comprises the following; 0o Solar Photovoltalic(SPV) modules. 0o SPV Charge Controller. 0P Battery Bank.Solar Photovoltalic(SPV) modules: The heart of any SPV system is the Solar cell, a semiconductor device having a simple p-n junction and which when exposed to sunlight produces DC electricity. A number of Solar cellsare interconnected in series combination and hermetically sealed between a toughened andhighly transparent front glass cover and encapsulant materials to form a Solar Photovoltaicmodule.
  • 3. SPV Charge Controller: In any Solar system for trouble free operation, the storage battries need to be maintainedinhealthy condition. For this, the battries should neither be discharged below a certain limit norover charged beyond a set limit. The load which draws the electrial energy from the batterycharge level is high, the electricity source viz., the SPV modules are disconnected from thebattery. The battery charge status being low or high is indicated by the glow of red or yellowLED and whenever the battery is getting charged green LED lights up. The following are thefutures of the Charge Controller are: 0u A lightning protection-unit, which protects the system from any lightning that may strike the modules kept exposed in the open atmosphere. 0h Protection against any accidental reverse connection of battery bank. 0r Blocking diode which prevents reverse flow of current from battery to SPV Module when the battery is not generating power in the night due to absence of sunlight. 0h MCB to protect against any accidental shorting of load terminals. 0C Batteries: The electrical energy generated by SPV modules can not be stored in themselves.Moreover, no energy is generated during night time and on cloudy days the generation is muchless. Batteries are therefore, required for storing energy. The battery bank used in the system is12V, 120AH capcacity lead acid tubular positive plate, low maintenance type or 12 volt, 80AHValve Regulated Lead Acid(VRAL) type battery conforming to BIS and TEC spec.COST: The major challenge of Solar power is that it has most expensive equipment that the ruralpeople cannot afford. It is beyond their monthly incomes but they would not mind to spend fewmultiple installments per month. For example: it would be difficult for a rural person to pay Rs600 electricity bill rather they can afford to pay Rs 20 per day. By this we can realise the fact thatneed to be provided with financing such that the pay back patterns synchronized with theirincome patterns. Rural banks provide loans for income generating activities and the RANSS private Ltd, toconceptualise that solar plates providing home electricity could be used for generating income.The rural banks provide loans for the installation of Solar plates for home electricity. This is alsosupported by the government Solar subsidies. Therefore, every rural citizen can afford Solar home electricity with short pay backpatterns. This arrangement of credit to the customers is an added advantage. The estimation for ahouse for installation of Solar plates is Rs.15000. This is a one time cost and is very beneficial in
  • 4. the long run. The banks supports each customers with a loan of Rs. 10000 to 12000. The onlycost that the customer should bear is the maintenance cost which is nominal.ESTIMATION OF COST: Suppliers: A Solar panel consists of 4 key components namely the Solar photovoltaicmodule(solar-cel panel), charge controller and lighting system(lamps). The relative rates of thecomponents are: pvm-Rs.4500, installation and wiring-Rs.700, battery-Rs.4000, invertor-Rs.3000, transportation charge(incl. all other charges) Rs.3000. So it all comes to total figure of15,200. The company will be selling it for Rs.20000 with a profit margin of Rs.4800.MARKET:Suppliers: RANSS purchaes Solar panels from TATA BP suppliers in Karnataka. The batteriesare purchased from Shakthi electronics and Anand electronics in karnataka. For rural IndiaRANSS needed electronic components that ever rugged, even if that meant making trade oftechnical sophistication. The company will maintain high degree of transparency and ready tohelp them incase of constraints and challenges and the company main motto is to maintain agood relationship with the suppliers so that there will be a continues supply of the product.BUSINESS: RANSS Pvt. Ltd, being new product business it is focusing on two rural areas. Tuni,Yellamanchilli in the east godavari district AP, the company is targeting 200 households in eachvillage that counts to 400 households in whole. The initial investment will count to15200*400=6080000 will be the expeted estimation. So, the business have a huge scope ofexpansion as more than 60% of India has rural population and the business will contribute byusing solar enery which is the best and guaranteed source of energy.
