1. INTRODUCTION
1.1 Introduction of Chapter
Around 70% of the State's population is living in rural areas. People inrural areas
should have the same quality of life as is enjoyed by people living insub urban and
urban areas. On account of poverty, unemployment, poor andinadequate
infrastructural facility has caused migration of the rural people to urban.Hence,
created slum in these region consequently social and economic tensionhas resulted
in urban areas. Hence, rural Development which is concerned with economic growth
and social justice, improvement in the living standard of the rural people by providing
adequate and quality social services and minimum basic needs becomes essential.
The present strategy of rural development mainly focuses on provision of basic
amenities and infrastructure facilities through innovative program of wageand self-
employment. For economic improvement of local people the above goals will be
achieved by various program being implemented creating partnership with
communities, non-governmental organizations, community based organizations,
institutions.
The Government's policy and program have laid emphasis on poverty,generation of
employment and income opportunities and provision of infrastructureand basic
facilities to meet the needs of rural poor.
As a measure to strengthen the grass root level democracy, the Government is
constantly endeavouring to employ Panchayat Raj Institutions interms of functions,
powers and finance.

2 Literature Survey
2.1 Electricity in village
Rural electrification is the process of bringing electrical power to rural and remote
areas. Electricity is used not only for lighting and household purposes, but it also
allows for mechanization of many farming operations, such as threshing, milking,
and hoisting grain for storage. In areas facing labour shortages, this allows for
greater productivity at reduced cost
In December 2011, over 300 million Indian citizens had no access to frequentelectricity. Over one third of India's rural population lacked electricity, as did 6% of
the urban population. Of those who did have access to electricity in India, the supply
was intermittent and unreliable. States such as Gujarat, Madhya Pradesh, etc.
provide continuous power supply.
India's Ministry of Power launched Deen Dayal Upadhyaya Gram Jyoti Yojana
(DDUGJY) as one of its flagship programme in July 2015 with the objective of
providing round the clock power to the rural areas. It focuses on reforms in rural
power sector by separation of feeder lines (rural households & agricultural) and
strengthening of transmission and distribution infrastructure. The earlier scheme for
rural electrification viz. Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY) has
been subsumed in the new scheme as its rural electrification component.
In Gujarat most of the village get 24/7 electricity supply. But, use of renewable
energy sources is very less.

2.2 Government Norms (Rules & Regulations)
The activities to be supported should lead to promotion of sustainable infrastructure
development in rural and agriculture & allied sector.
The activities should include a component for documentation of experience during
implementation.
Special thrust to North-East Regions including Sikkim, Eastern Region and Hilly
Himalayan States of Uttarkhand, Himachal Pradesh and J & K, for creation of
experimental/ promotional infrastructure as also for supporting all other activities.
The experimental projects/activities to be supported should be prototypes of
innovative/ experimental/demonstrative nature. Infrastructure assets created should
result in improvement or generate demand for other infrastructures of higher order.
Under Deendayal Upadhyaya Gram Jyoti Yojana, electricity distribution infrastructure
is envisaged to establish Rural Electricity Distribution Backbone (REDB) with at least
a 33/11KV sub-station, Village Electrification Infrastructure (VEI) with at least a
Distribution Transformer in a village or hamlet, and standalone grids with generation
where grid supply is not feasible.
This infrastructure would cater to the requirements of agriculture and other activities
in rural areas including irrigation pump sets, small and medium industries, khadi and
village industries, cold chains, healthcare and education and IT. This would facilitate
overall rural development, employment generation and poverty alleviation.
Subsidy towards capital expenditure to the tune of 90% will be provided, through
Rural Electrification Corporation Limited (REC), which is a nodal agency for
implementation of the scheme. Electrification of un-electrified Below Poverty Line
(BPL) households will be financed with 100% capital subsidy @ Rs.1500/- per
connection in all rural habitations.
The Management of Rural Distribution is mandated through franchisees. The
services of Central Public Sector Undertakings (CPSU) are available to the States
for assisting them in the execution of Rural Electrification projects.

2.4 Approach So Far
Kutir Jyoti Program (KJP)
KJP was initiated in 1988-89 to provide single point light connection (60 w) to all
Below Poverty Line (BPL) households in the country. KJP provides 100% grant for
one time cost of internal wiring and service connection charges and builds in a
proviso for 100% metering for release of grants. Nearly 5.1 million households have
been covered under the scheme to date. The scheme was merged into the
Accelerated Electrification of One Lakh Villages and One Crore Households in
May2004 and now into the RGGVY.
Accelerated Rural Electrification Program (AREP)
The AREP operational since 2002, provides an interest subsidy of 4% to states for
rural electrification (RE) programs. The AREP covers electrification of un-electrified
villages and household electrification and has an approved outlay of Rs.560 crore
under the 10 the Plan. The interest subsidy is available to state governments and
electricity utilities on loans availed from approved financial institutions like the REC
(Rural Electrification Corporation), PFC (Power Finance Corporation) under the
Rural Infrastructure Development Fund (RIDF).

Pradhan Mantri Gramodaya Yojna (PMGY)
The PMGY launched in 2000-2001 provided additional financial assistance for
minimum services by the central government to all states on a 90% loan and 10%grant basis. These included rural health, education, drinking water and rural
electrification. The PMGY with an outlay of about Rs.1600 crores during the 10th
Plan period was being coordinated and monitored by the Rural Development
Division of the Planning Commission. Under PMGY states had the flexibility to
decide on the interreallocation of funds amongst the 6 basic services. Thus states
could enhance allocations to expedite the pace of rural electrification.
Deendayal Upadhyaya Gram Jyoti Yojana
It is earlier known as Rajiv Gandhi Grameen Vidyutikaran Yojana. Government of
India, in April 2005, launched the scheme Rajiv Gandhi Grameen vidyutikaran
Yojana Scheme of Rural Electricity Infrastructure and Household Electrification for
electrification of un-electrified villages and providing access to electricity to all rural
households in the country, including electrification of un-electrified habitat popu lation
of above 100, providing free electricity connections to BPL households.
The Remote Village Electrification (RVE) Program
Since 2005, the RVE program of the Ministry of New and Renewable Energies
(MNRE) has been supplementing the efforts of the Ministry of Power (MoP) through
complementary measures for the provision of basic lighting/electricity facilities
through renewable energysources. The Remote Village Electrification program
(RVE) is responsible for electrifying un-electrified remote census villages and remote
un-electrified hamlets of electrified census villages where grid connection is either
not feasible or not economical (because they are located in forests, hills, deserts or
islands) and where DDG projects are not implemented by the RGGVY of the Ministry
of power.

4 Planning Proposal
4.1 Design Selections
In this project I am working in a village on solar theme, so while designing I
have to study about solar components and their various characteristics.
Mainly there are four components are used in any solar project.
1. Solar Panel
2. Battery
3. Inverter
4. Load
1. Solar Panel
Solar Panel refers to a panel designed to absorb the sun's rays as a source of
energy for generating electricity or heating.
A photovoltaic (in short PV) module is a packaged, connected assembly of typically
6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic
system that generates and supplies solar electricity in commercial and residential
applications. Each module is rated by its DC output power under standard test
conditions, and typically ranges from 100 to 365 watts. The efficiency of a module
determines the area of a module given the same rated output – an 8% efficient 230
watt module will have twice the area of a 16% efficient 230 watt module. There are a
few solar panels available that are exceeding 19% efficiency.
A single solar module can produce only a limited amount of power; most installations
contain multiple modules. A photovoltaic system typically includes a panel or an
array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker
and interconnection wiring.
8/17/2019 Vishwakarma Yojana Report Electrical
22/33
Vishwakarma Yojana: Santej, Gandhinagar
P a g e 2
2
Gujarat Technological University, Gujarat
There are three types of solar modules:
1. Monocrystalline
2. Polycrystalline
3. Thin film
Monocrystalline modules have efficiency about 16-20% whereas Polycrystalline
modules have 12-17% and thin film has 6-12%.
Polycrystalline modules occupy more space than Monocrystalline modules.
2. Battery
Deep-cycle, lead-acid batteries are widely used in renewable energy and grid-
backup system, and are ideally suited for these applications because of their long,
reliable life and low cost of ownership.
Deep cycle refers to the fact that in a solar power system, it is likely that the battery
will become charged during a sunny day, then they may become almost fully
discharged with use, before they are again fully charged.
In stand-alone systems, the power generated by the solar panels is usually used to
charge a lead-acid battery. Other types of battery such as nickel-cadmium batteries
may be used, but the advantages of the lead-acid battery ensure that it is still the
most popular choice. A battery is composed of individual cells; each cell in a lead-acid battery produces a voltage of about 2 Volts DC, so a 12 Volt battery needs 6
cells. The capacity of a battery is measured in Ampere-hours or Amp-hours (Ah).
Days of autonomy is another important aspect while selecting battery. This term
refers to the maximum days for which battery can supply power without being
charged. In India, 3 days are considered as standard days of autonomy.

3. Inverter
A solar inverter, or PV inverter, or Solar converter, converts the variable direct
current (DC) output of a photovoltaic (PV) solar panel into a utility frequency
alternating current (AC) that can be fed into a commercial electrical grid or used by a
local, off-grid electrical network. It is a critical BOS –component in a photovoltaic
system, allowing the use of ordinary AC-powered equipment. Solar inverters have
special functions adapted for use with photovoltaic arrays, including maximum power
point tracking and anti-islanding protection.
Solar inverters may be classified into three broad types:
Stand-alone inverters, used in isolated systems where the inverter draws its DC
energy from batteries charged by photovoltaic arrays. Many stand-alone inverters
also incorporate integral battery chargers to replenish the battery from an AC source,
when available. Normally these do not interface in any way with the utility grid, and
as such, are not required to have anti-islanding protection.
Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie
inverters are designed to shut down automatically upon loss of utility supply, for
safety reasons. They do not provide backup power during utility outages.
Battery backup inverters, are special inverters which are designed to draw energy
from a battery, manage the battery charge via an onboard charger, and export
excess energy to the utility grid. These inverters are capable of supplying AC energy
to selected loads during a utility outage, and are required to have anti-islanding
protection
Solar inverters use maximum power point tracking (MPPT) to get the maximum
possible power from the PV array.
There is another important part in inverter known as charge controller.
A charge controller may be used to power DC equipment with solar panels. The
charge controller provides a regulated DC output and stores excess energy in a
battery as well as monitoring the battery voltage to prevent under/overcharging.
More expensive units will also perform maximum power point tracking. An inverter
can be connected to the output of a charge controller to drive AC loads.

4. Load
This type of solar system is by far the most simply. The solar modules are connected
directly to a load which is often a motor. Whenever the sun is up and shining the
motor will work. Unlike electronics a motor can take a variable voltage and current
input without being damaged. A solar powered attic fan is a great example of this
system type.
Another good example is a water pump. With a water pumping system, instead of
storing energy water is stored. For example, if a rancher is pumping water for cows,
the water is stored in a tank and that tank is used when needed to fill troughs for the
animals. With most modern water pumping systems there is another component
typically in the system between the solar array and the pump that controls the output
of the solar array to better optimize the pumps operation.
DC Loads connected to panels may be lamp in solar street light.

4.2.2 Sustainable/ Renewable Energy source Planning
Design Steps for Solar Power PV Module
Requirement
In present scenario, generation of power is quite less than demand. And the differencebetween them is increasing rapidly. So, it‟s advantageous if a provision is there for thebuilding to generate electricity for its own demand. Also, excessive power generated can betransferred to the grid which would help in bridging the gap between generation anddemand. Solar rooftop plan is the best option for economic power generation.

It reduces requirement of land for solar Power.
It reduces need for additional transmission infrastructure
For consumers, it reduces
The dependency on grid power.
Mitigates diesel generator dependency.
Long term reliable power source.
Most suitable for commercial establishments
Max generation during peak usage time. Solar power cost is close to the commercial power cost.
Solar power cost is fixed for 25 years
As per the requirement of electricity in my village I propose a solar roof top plan for thePanchayat building in my village.

PV module Calculations
A single solar module can produce only a limited amount of power; most installations
contain multiple modules. A photovoltaic system typically includes a panel or an
array of solar modules, a solar inverter, and sometimes a battery.
As per our system requirement we select Monocrystalline PV module For Panchayatbuilding.

Determine power consumption demands
The first step in designing a solar PV system is to find out the total power and energy
consumption of all loads that need to be supplied by the solar PV system as follows:
Table 5
ComponentNumber ofcomponent
rating Working hour
Ceiling fan 3 60W 7
T-12 fluorescenttube light with
electromagneticballast
3 55W 7
Calculate total Watt-hours per day needed from the PV modules
Multiply the total appliances Watt-hours per day times 1.3 (the energy lost in the
system) to get the total Watt-hours per day which must be provided by the panels.
Total power = {(60*7*3) + (55*7*3)} *1.3
= 3.139 KWh
Size of PV modules
Different size of PV modules will produce different amount of power. To find
out the sizing of PV module, the total peak watt produced needs. The peak
watt (Wp) produced depends on size of the PV module and climate of site
location.
We have to consider “panel generation factor” which is different in each site
location. The panel generation factor is 4.2 To determine the sizing of PV
modules, calculation is as follows:
= 3139/4.2
= 747.38 Watt-peak

Calculate the number of PV panels for the system
Divide the answer obtained in item 2.1 by the rated output Watt-peak of the PV
modules available to you. Increase any fractional part of result to the next highest full
number and that will be the number of PV modules required.
= 747.38/110
= 7 Modules
Inverter Calculation
An inverter is used in the system where AC power output is needed. The input
rating of the inverter should never be lower than the total watt of appliances.
The inverter must have the same nominal voltage as your battery.
For stand-alone systems, the inverter must be large enough to handle the total
amount of Watts you will be using at one time.
Connected Load = 3(55) + 3(60)
= 345 watt
The inverter size should be 25-30% bigger than total Watts of appliances.
Hence inverter size should be 440watt or greater.
Battery Size
The battery type recommended for using in solar PV system is deep cycle battery.
Deep cycle battery is specifically designed for to be discharged to low energy level
and rapid recharged or cycle charged and discharged day after day for years. The
battery should be large enough to store sufficient energy to operate the appliances at
night and cloudy days. To find out the size of battery, calculate as follows:

Battery Capacity (Ah) = Watt-hours per day used by appliances x Days of autonomy(0.85 x 0.6 x nominal battery voltage)
= 2415 X 3
0.85X0.6X12
=1183.82 Ah
Hence Battery should be rated 12 V,1200 Ah per 3 day autonomy.
Solar charge controller sizing
The solar charge controller is typically rated against Amperage and Voltage
capacities. Select the solar charge controller to match the voltage of PV array and
batteries and then identify which type of solar charge controller is right for your
application. Make sure that solar charge controller has enough capacity to handle
the current from PV array.
PV module specification
Pm = 110Wp
Vm = 12 v DC
Im = 6.6 A
Voc = 20.7 A
Isc = 7.5 A
Solar charge controller rating = (7 strings x 7.5 A) x 1.3 = 68.25 A
So the solar charge controller should be rated 80 A at 12 V or greater.

5 Recommendation & Suggestions
Implement the design of solar street light for streets of village.
Use LED Street Lights in solar power based design.
Use energy efficient equipment in public building i.e. LED lights, energy efficient
fans, electronic ballast tube lights, lighting voltage regulator etc.
Try to utilise day light in Panchayat Bhavan, school and bank.
Use small solar roof top plant in panchayat Bhavan.
Keep maintenance of electrical equipment i.e. water pump and motor, AC, fan etc.
Do regular energy audit of public building regularly. It will maintain the bill and
implementation of report may reduce bill.
Redesign the Panchayat Bhavan and Bank if possible, so they can use daylight and
save energy during day time.
Use solar power based irrigation system.
Aware public about energy conservation and let them know about difference
between
Less use of energy and energy conservation
Aware about renewable energy sources and its importance in terms of environment.
Though, such kind of plant are costly initially, they are economic in long run and give
pollution free energy.

6. Conclusion
As per problem observed in rural area preventive and renewable measures
aresuggested. Implementation of improvement will reduce problem in areaand
improve standard of living of village people. This can be resulted inimproving social
and economic effect of rural area on economy of thecountry and it may result
in more efficient use of infrastructure. By caringout the Vishwakarma Yojana project
work,I came to know that if proper planning and guidance is provided youth can
change thecomplete scenario of village.
More use of solar based energy resources in home and small public utility building
can reduce carbon footprint of village as well as reduce electricity cost in long run.
Maximum use of day light in Panchayat Bhavan and bank can reduce electricity bill.
Awareness about energy efficient equipment is important thing in conservation of
energy. Aware village dwellers about solar based power though they are getting 24*7
electricity supply. Because, solar power is the future of electricity and in long time we
will have free energy with one time capital investment and proper maintenance.
Thus, use of renewable energy, energy efficient equipment and proper use of energy
can push Santej village towards “Rurbanization”.
