basic principle of solar car is to use energy that is stored in a battery during and after charging it from a solar panel. The charged batteries are. Keywords: Solar cars, PV cells, Power trackers, Batteries. INTRODUCTION. A solar car is a solar vehicle used for land transport. Solar cars combine technology . A solar vehicle is an electric vehicle powered completely or significantly by direct solar energy. Usually, photovoltaic (PV) cells contained in solar panels convert.
Our vehicle is easy to handle and no fuel cost to the other existing vehicles. Regulations on exhaust emission from vehicle engines have been made progressively more and more stipend towards the year and beyond, Vehicle manufactures have been hence obliged to meet these standards by designing cleaner and fuel efficient engines and through provision for treatment of exhaust gases to satisfy the specified limits.
So to satisfy and overcome these two problems namely Pollution and Efficiency Hence a need for a change in the existing alternative system which can produce higher efficiency at minimum cost was thought about an attempt has been made to design and fabricate such an alternative system.
In order to achieve this saturation point we have to save and seek for some other source of power. This power, the alternate power must be much more convenient in availability and usage.
The next important reason for the search of effective, unadulterated power are to save the surrounding environments, including men, machine and material of both the existing and the next forth generation of pollution, the cause for many harmful happenings and to reach the saturation point.
The most talented power against the natural resource is supposed to be the electric and solar energies that best suit the automobiles.
The unadulterated zero emission electrical and solar power, is the only easily attainable alternate source. Hence we decided to incorporate the solar power in the field of automobile, the concept of many Multi National Companies MNC and to get relieved from the incorrigible air pollution.
This photoelectric effect is already explained in the above chapter. The output of the solar panel is normally D. When this happens, the extra energy gets stored in the batteries for later use.
When the solar may can't produce enough energy to drive the motor at the desired speed, the array's energy is supplemented with stored energy from the batteries. Of course, when the car is not in motion, all the energy from the solar may is stored in the batteries. There is also a way to get back some of the energy used to propel the car.
When the car is being slowed down, instead of using the normal mechanical brakes, the motor is turned into a generator and energy flows backwards through the motor controller and into the batteries for storage. This is known as regenerative braking. The amount of energy returned to the batteries is small, but every bit helps. It can be used places where, fuel based vehicles are banned due to production of pollution and noise.
Solar cells or photovoltaics collect the energy from the sun and converts it into usable electrical energy.
They are made from silicon by joining an n-type and a p-type silicon semiconductor, creating an electron rich and an electron poor layer. When sunlight strikes the cell, photons cause atoms of the semiconductor to free electrons, leaving behind positive charges.
The flow of electrons thus created constitutes an electromotive force that drives the current to charge a battery or power a motor. The cell's positive contact is on the bottom while the negative contact, or bus bar, is located on the top of the cell.
Each cell produces approximately. Connecting the cells in series, i. Parallel connections, i.
Therefore, connecting the cells in various series and parallel configurations produces modules of different voltages and currents.
To put the limitations of a solar car in perspective, a simple calculation will suffice. This term can be thought of as the amount of sunlight that reaches a sunny area on cloudless, summer day around noon.
Of this energy, average solar cells are only able to convert With cars running on Watts, efficiency is hypercritical. Therefore, advances in all aspects of engineering, from mechanical to electrical to materials and computer science are the key. The three primary areas of energy loss consist of aerodynamic drag, braking, and rolling resistance. To minimize aerodynamic drag, engineers make solar cells as sleek as possible. Rolling resistance is proportional to weight.
Hence solar cars should be engineered to be very light.
