Advantage of solar panels
Solar panels are a great way of cutting our
Solar energy is the most widely and easily available
energy source which can be used to produce
pollution free and eco – friendly electricity.
Government-funded solar electricity in India
was approximately 6.4 MW per year as of
25.1MW was added in 2010 and 468.3 MW in
As on 30 June 2015, the installed grid
connected solar power capacity is
India expects to install an additional
10,000 MW by 2017, and a total of
100,000 MW by 2022
Rajasthan is one of the states of India in the field of solar energy.
The total photovoltaic capacity has passed 500 MW, reaching
510.25 MW at the end of the 2012-13.
The district of Jodhpur leads with 42 projects totaling 293 MW,
followed by Jaisalmer and Bikaner. In total there were 84 projects
with installed capacity of 512.9.
A 4,000MW Ultra Mega Green Solar Power Project (UMPP) is
being built near Sambhar Lake in Rajasthan. Upon Completion, it
would be world's largest Solar Power Plant. It is expected to be
built in 4 phases, with the first phase likely to be commissioned
by the end of 2016 with 1,000 MW capacity. The total cost of
each phase of the project is estimated to be R70 billion and the
entire project is expected to be completed in 7 years.
The present Prime Minister Narendra Modi has put great
emphasis on solar projects and is inviting FDI in this sector
This project has its major use in electricity savings in
the building blocks, room etc.
The project is basically a solar power system, so it is
very useful in saving of electricity. Mainly in building
there is a problem of the electricity interruption so
use to solar system we solve this problem.
By using this project we reduce the electricity bill of
the building block and save the money up to 10800
rupees in one year for load 600 watt Running for 8
Installation cost of this we can recover in 5 years and
the age of solar panel is 25 year approximately. So
we have 20 year for free electricity use.
Polycrystalline Solar panels
Solar charge controller
Wire and other equipment
Polycrystalline solar panel is a type of solar
panel which made of polycrystalline silicon.
Many crystalline silicon module
manufactures offer a warranty that
guarantees electrical production for 10
years 90% of rated power output and after
that 80% .
It is also recyclable.
It is possible to recover more than 80% of
the incoming weight
The current we get from
solar panels will not
remain constant through
out the day, so many ups
and downs will be there
so that we can not
Modules directly to
charge or battery it will
spoil or battery overtime
So we need a device cold
solar charge controller to
control the current
generate from solar
pv module is dc
voltage but the load
are ac equipment so
we have use an
inverter to convert
dc power to ac
Battery stored an
coming from pv
system when grid
is off and also
coming from ac
In this 600 watts solar setup, we will get 500
watts current for sure from solar panels in day
time this means 8 am to 5 pm.
We can use the free current from PV modules
during this day time by manually switching off
the Input to Inverter (power supply from grid), so
that the inverter battery will be charged with
available solar power.
While the battery is getting charge from solar
panels, concurrently we can use the battery
power to power up our home.
So, with solar power, the battery will be get
charge and on the other side the battery will
deliver current to inverter for powering up our
gadgets, this happens simultaneously.
As we have only 600 watts solar panel setup, we should not use
more than 500 watts power from inverter during day time.
Lets see how many Fans, lights and TV can we use with this
500watts power during day time.
1 fans – 80 watts
1Cooler – 180
One pc – 150 watts
Total – 410 watts
(As we don’t use lights during day time, i exclude it from this
So, we use 410 watts power during day time, then what happens
to the excess 90 watts of current generated by solar panels
The excess 90 watts will go directly in to your battery storage,
not only that 90 watts, if you switch off the pc for 1 hour in day
time, that 150 watts used by pc also goes to battery storage

Calculation for Solar Panel Installation
We have the total load = 600watts
Sun rays time duration in a day (9am to 5pm) = 8hr
So, Energy consume in this time duration by load = 600*8
Daily unit for consume by total load = (4800/1000)
= 4.8unit (Approx 5 unit)
Monthly unit = 5*30=150
Cost of 1 unit = 6/-
Total monthly cost (bill) = 150*6=900
Annual cost = 12*900=10800/-
So in one year this project recover = 10800/-
Then required amount (55000) of installation recovers in 5
But a solar panel age is 25 year
So we have 20 year for free electricity use.
Total amount of billing in 25yr for 600watt load = 25*10800
= 2, 70,000/-
So amount of bill save= 270000-55000
No fuel requirement compare to conventional
No wastes are produced
Less maintenance cost
Pollution free because hazard gases like CO2
SO2,CO,CFC NO2 are not reduces
Most parts of a solar module can be recycled
including up to 97% of certain semiconductor
materials or the glass as well as large
amounts of ferrous and non-ferrous metals.
Since 2010, there is an annual European
conference bringing together manufacturers,
recyclers and researchers to look at the future
of PV module recycling.
