1. INTRODUCTION
Renewable Energy (RE) is now making a noticeable impact especially in the lives of
rural masses. Simultaneously though, its use for urban and semi-urban applications is also
growing by the day. The Indian RE programmed was amongst the first few such programmed to
shape up globally. Since then, it has assumed respectable market leadership position in a few
areas in wind energy and solar energy. Solar energy is more predictable and dependable than
any other available renewable source of energy. India has significant sun shine for over 300
days per year which is approximately 3000hrs of sunshine every year. But only 0.2% of total
energy production is contributed by the installed capacity. Solar Energy products like solar
panels 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, the
Indian government installed solar-powered street lights to utilize funds devoted to non-
conventional energy. Howerever, in the absence of an organization to assume responsibility, very
little effort was subcequently put it for proper maintainence of these lights. March was followed
by the Indian summer, when abundant sunshine often resulted in the overheating of lights
stopped functioning, thereby creating a perception among villages that solar lights were fragile
and unlikely to function for more than three to four months. In 1982 high power usage solar
pannels 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 load
when sufficient sunshine is available. In India Monocrystalline Solar cells, connected suitable to
meet the voltage requierments. But Silicon is expensive and short in supply. The price of Silicon has
increased upto 50% in the past 3 years. As Silicon is very expensive and scarce looking for
substitutes 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 by
using the thin plates we can produce the electricity even in the shaded region. Even there is no
high sun light, i.e, on a cloudy day, we can produce electricity throughout the year which is the
main challenge in the yesters years. By using these thin plates we can cut the manufacturing
cost around 40% which is more economical so that rural people with a minimun living standards
can also afford to purchase. Even our proposal is to use invertor for a storage as per the
customer 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 Crystalline
Silicon 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 easy
to use, eleminating the need for mounting structure for a solar array. The most intresting feature
of these thin film Solar panels is, they do not require direct sunlight for operation. They can even
work under shade. So we need not remove trees in the surroundings and there is no problem even
though it is surrounded by the taller buildings.
PRODUCT DESCRIPTION:
The Solar Photovoltalic(SPV) power source and non conventional energy source deployed
for 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 cells
are interconnected in series combination and hermetically sealed between a toughened and
highly transparent front glass cover and encapsulant materials to form a Solar Photovoltaic
module.

3. SPV Charge Controller:
In any Solar system for trouble free operation, the storage battries need to be maintained
inhealthy condition. For this, the battries should neither be discharged below a certain limit nor
over charged beyond a set limit. The load which draws the electrial energy from the battery
charge level is high, the electricity source viz., the SPV modules are disconnected from the
battery. The battery charge status being low or high is indicated by the glow of red or yellow
LED and whenever the battery is getting charged green LED lights up. The following are the
futures 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 much
less. Batteries are therefore, required for storing energy. The battery bank used in the system is
12V, 120AH capcacity lead acid tubular positive plate, low maintenance type or 12 volt, 80AH
Valve 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 rural
people cannot afford. It is beyond their monthly incomes but they would not mind to spend few
multiple installments per month. For example: it would be difficult for a rural person to pay Rs
600 electricity bill rather they can afford to pay Rs 20 per day. By this we can realise the fact that
need to be provided with financing such that the pay back patterns synchronized with their
income patterns.
Rural banks provide loans for income generating activities and the RANSS private Ltd, to
conceptualise 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 also
supported by the government Solar subsidies.
Therefore, every rural citizen can afford Solar home electricity with short pay back
patterns. This arrangement of credit to the customers is an added advantage. The estimation for a
house 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 only
cost 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 photovoltaic
module(solar-cel panel), charge controller and lighting system(lamps). The relative rates of the
components 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 of
15,200. 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 batteries
are purchased from Shakthi electronics and Anand electronics in karnataka. For rural India
RANSS needed electronic components that ever rugged, even if that meant making trade of
technical sophistication. The company will maintain high degree of transparency and ready to
help them incase of constraints and challenges and the company main motto is to maintain a
good 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 each
village that counts to 400 households in whole. The initial investment will count to
15200*400=6080000 will be the expeted estimation. So, the business have a huge scope of
expansion as more than 60% of India has rural population and the business will contribute by
using solar enery which is the best and guaranteed source of energy.
