ABSTRACT
The sun is probably the most important source of renewable energy available today. The Earth
receives an incredible supply of solar energy. The sun, an average star, is a fusion reactor that
has been burning over 4 billion years. It provides enough energy in one minute to supply the
world's energy needs for one year. In one day, it provides more energy than our current
population would consume in 27 years. In fact, the amount of solar radiation striking the earth
over a three-day period is equivalent to the energy stored in all fossil energy sources. Here in
India, especially Rajasthan where temperatures over the last few years have risen from 32deg C
to 36deg C to last summer of 42deg C to 46 deg C, thus solar energy is available in great amount.
As a rule of thumb, the sun supplies around one kilowatt of energy per square meter, which just
happens to be the half roof area of a typical E-rickshaw.
GRIDTECH
An exhibition on Student Innovation ‘Gridtech 2015’ was held at Pragati Maidan from 8th
to 10th
April in National Capital, where students of different technological institutions from all over the
India had participated and display their innovative projects.
We the students of GB Pant Engineering College, Okhla, New Delhi had showcased an
innovative E-rickshaw that runs on solar energy and the solar panels are installed at the top of its
roof which can absorb the direct sunlight. This E-rickshaw is has number of benefits to rickshaw
puller, passengers as well as the Environment. This E-rickshaw is comfortable to sit, and can
load four passengers in a single ride which reduce the efforts of a rickshaw puller. It is eco-
friendly and saves fuel and electricity, runs on solar energy this E-rickshaw can run at maximum
speed of 25kmpl and the shockers that are been installed make the ride safe and comfortable on
broken roads too.
The E-rickshaw can be driven over 100kms on a single charge as compare to 40% more than
traditional E-Rickshaw. Apart from other benefits, this solar E-Rickshaw cuts cost upto 60% per
km as compare to ordinary E-rickshaw.
The Union Minister of Power Mr. Piyush Goyal had appreciated the efforts by us. The team
Members Samnit Dua, Hardik Manocha, Shashank Narayan, Naveen Kumar, Anupam Pandey
under the guidance of Dr.Vibhakar Shrimali had completed this project.
This solar E-rickshaw also increases the battery life by 1.5 times than ordinary E-Rickshaw. This
solar E-Rickshaw owner can earn about 96,884 INR more than other which is more than its cost.

ECONOMICS OF PROJECT
1) 50% more battery life:
Cost of battery set= Rs 24,000
Average life of battery= 6 months
Battery life of solar rickshaw=9 months
Hence, Total benefits=Rs 16,000/annum ……………(a)
2) Electricity benefits:
Avg. rate of electricity=Rs 6/unit
Units consumed for full charge (E-rickshaw)=6 units
Total units consume per year=6*365 =
2190 units
Total cost of electricity per year (E-rickshaw )= 2190*6= Rs
13,140
Cost per km for E-rickshaw(e-rickshaw)=
60 paisa
Cost per unit for solar rickshaw= 24paisa
Total cost benefits per year= Rs 7,884………………..(b)
3) As we observe by the E-rickshaw owners reviews that the rickshaw they drive for about 8 hrs
and earn approx. Rs 400in that time.As our batteries are also charging at same time our solar
rickshaw runs 12hrs a day. According to that the rickshaw owner can earn Rs600 a day.The total

5. 5
amount the rickshaw owner can earn more in a year = 200*365=Rs
73,000………………………………….. (c)
The total benefits in an year is up to
Rs96,884/-…………………………………………………………………. (a+b+c)
ADVANTAGES
• Battery will get charged during running and waiting time.
• Due to simultaneously charging, the rickshaw mileage increases.
• Battery replacement time will be less as we can control charging cycles of battery.
• Our solar e-rickshaw is cost efficient than other solar e-rickshaw.
• Can be driven more than 100kms on a single charge.
• Slow charging cycles which resultsin increasing battery life.
• 50% more battery life.
• No Use of electricity.
• Have better performance.
• Lesser cost in terms of long run.
• To reduce the use of fossil fuels.
• Eco-friendly in nature.
• High future prospects in Renewable energy field.

FUTURE ASPECT
• To increase the efficiency of solar cell.
• To increase the yield of solar cell.
• To reduce weight of solar panel using the flexible panels.
• To reduce the weight of the frame and body.
• To use light weight high energy density battery.
• To use alternator or regenerative braking down the slope to charge the battery.
• To use sensors and actuators for speed control and battery indicator.
