Main contents

Solar panels are a great way of cutting our electricity bills.

Solar energy is the most widely and easily available energy source which can be used to produce pollution free and eco – friendly electricity.

INTRODUCTION

Government-funded solar electricity in India was approximately 6.4 MW per year as of 2005

25.1MW was added in 2010 and 468.3 MW in 2011

As on 30 June 2015, the installed grid connected solar power capacity is 4,060.65 MW

India expects to install an additional 10,000 MW by 2017, and a total of 100,000 MW by 2022

Solar power in India

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

Solar power in Rajasthan

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 hour.

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

Wire and other equipment

MAIN COMPONENTS

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

Polycrystalline solar panel

SOLARCHARGE CONTROLLER

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 connect solar photovoltaic Modules directly to charge or battery it will spoil or battery overtimeSo we need a device cold solar charge controller to control the current

INVERTER

The voltage 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 power

BATTERY

Battery stored an electrically power coming from pv system when grid is off and also store power coming from ac line.

SCHEMATIC DIAGRAM

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.

Working of this project

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

list.) 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 directly.

Calculations for parameter rating

We have the total load = 600wattsSun rays time duration in a day (9am to 5pm) = 8hr

So, Energy consume in this time duration by load = 600*8 = 4800wats

Daily unit for consume by total load = (4800/1000) = 4.8unit (Approx 5 unit)Monthly unit = 5*30=150Cost of 1 unit = 6/-

Total monthly cost (bill) = 150*6=900Annual cost = 12*900=10800/-So in one year this project recover = 10800/-

Installation money recovery

Then required amount (55000) of installation recovers in 5years approximately.

But a solar panel age is 25 year

So we have 20 year for free electricity use.  

Now Total amount of billing in 25yr for 600watt load = 25*10800 = 2, 70,000/-So amount of bill save= 270000-55000 = 2,15,000/-

No fuel requirement compare to conventional power plant

No wastes are produced Less maintenance cost Pollution free because hazard gases like CO2

SO2,CO,CFC NO2 are not reduces Recycling

Advantage of solar panels

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.
