AIM OF OUR PROJECT

By using solar tree we can provide mobile charging and public lightning In any area i.e. title of our project

EXISTED SYSTEMSolar street light technology

In this solar field existed System is solar street lightTechnology and another is To produce home required Power

DRAWBACKS OF EXISTED SYSTEM

It is used only for just lightning purpose only. In home applications we definitely used INVERTER. Circuit complexity is high. Less amount of efficiency .

OVER COME METHOS

Providing more applicationsWith out using inverter we providing the usage of electronic devices in our home.Reducing the circuit complexity. From less efficiency usage we will connect more than two devices by using low voltage battery.

WHAT IS SOLAR TREETREE stands for T=TREE GENERATIING R=RENEWABLE E=ENERGY and E=ELECTRICITY

This is like a tree in a structure and the panels are like leaves of the tree which produces Energy.

COMPONENTS OF SOLAR TREE The solar tree consists of manly five parts to design.

Solar Panel.

Long tower.

LEDs.

Batteries.

Stems.

WHY WE CALL IT AS SOLAR TREE Tree can produce their own food material for human beings by the

process called PHOTOSYNTHESIS.

Likewise in solar tree solar plates are producing energy for the society.

SOLAR PANELS

In our project we use 15 watt solar PanelsFrom each solar panel we get 20-25% efficiencyI.E approximately 3 watt and 18-19 v

SOLAR MANAGEMENT UNIT WITH BATTERY

S.M.U is nothing but mini inverter and controllerIn our project we use Lead acid Battery with 12v with portable size

S.M.U COMPARISION

D.C BULB WITH L.D.R SENSOR

In this project we use 6 watt D.C bulb with L.D.R sensor The D.C bulb will glow with out battery in the temp of 28-30 degree centigrade by using 15 watts solar panel.

LED

(LED light) A light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many device.

LEDALLOWS THE CURRENT TO FLOW IN ONE DIRECTION.

LDR

LDR(LIGHT DEPENDENT DIODE). A type of resistor that decreases in resistance when it is exposed to light

RESISTS THE FLOW OF CURRENT.

LDR IN A CIRCUIT

MOBILE CHARGING

Charge controller is used for providing charging to the Mobile phones and Laptops The charge controller is convert Direct current to alternativeCurrent.

Solar cell phone chargers use solar panels to charge cell phone batteries. They are an alternative to conventional electrical cell phone chargers and in some cases can be plugged into an electrical outlet.

There are also public solar chargers for mobile phones which can be installed permanently in public places such as streets, park and squares. 

SOLAR PANEL CALCULATION

Diagram of Solar tree electricity production by month

Let us take an example Comparing with the household

We are observing the different purposes we are using the power let’s see APPLICATION

PRICE

T.V 130 FAN 100 OTHER APPLICATIONS 120

PER MONTH = 350 RsPER YEAR = 1800Rs

We observe the elcetricity bill are incress so approximatly for last 10 years nearly 25% By observing now a days scasity of water difficult to generate energy so next 10-15 years the electricity bill are increses app 35-40% so

cost for 25 years ==145000(app)

IF WE USE SOLAR TREE FOR THIS ........We are giving continues supply over 24 hours

APPLICATION

solar pannels wa

T.V 500 FAN 200 OTHER APPLICATIONS 300

TOTAL LOAD 1000

FOR 25 YEARS -- 90000(app)

Solar pannel cost per 100w -9000 2000 w we reqire 90000(app)

WHY IT IS BETTER THAN TRADITIONAL SYSTEMS

for the same amount of energy we require only 0.10-0.12 acres of land in case of solar tree

APPLICATIONS Street Light. House Supply. Mobile charging Industrial Power Supply.

ADVANTAGES No air pollution. We wouldn’t have to worry as much about future energy sources. low maintenance Land requirement is very less.

DISADVANTAGES

Costly.

Hazards to eyesight form solar reflectors.

CONCLUSION

Saving of land, this project is very successful one.

increases the efficiency Providing power supply for household applications

The main aim of this project is upliftting the public

opinion on R E S

To see the future

of energy…..
