WHAT IS A SOLAR CAR?

A solar vehicle is an electric vehicle powered by a type of renewable energy, by solar energy obtained from solar panels on the surface (generally, the roof) of the vehicle.

SOLAR CELL A solar cell converts solar energy to electrical energy. Photons in sunlight

provide the energy that moves electrons from one layer of a semi-conducting metallic wafer to another. The movement of the electrons creates a current.

Solar cells are devices which convert solar energy directly into electricity. The most common solar cells function by the photovoltaic effect. Photo- means light and -voltaic means electrical current or electricity.

SOLAR ARRAY

The solar array is the vehicle's only source of power during the cross-country Race. The array is made up of many (often several hundred) photovoltaic solar cells.

Solar array

---------------------------------------------------m.kandemir

The power produced by the solar array varies depending on the weather, the sun's position in the sky, and the solar array itself. On a bright, sunny day at noon, a good solar car solar array will produce well over 1000 watts (1.3 hp) of power. The power from the array is used either to power the electric motor or stored in the battery pack for later use

POWER TRACKERS

power trackers condition the electricity coming from the solar array to maximize the power and deliver it either to the batteries for storage or to the motor controller for propulsion. When the solar array is charging the batteries, the power trackers help to protect the batteries from being damaged by overcharging. The number of power trackers used in a solar car varies with each team's design.Power trackers can be very lightweight and commonly reach efficiencies above 95%.

ELECTRIC MOTOR

An electric motor is the basic and the most important part of a solar car. It should work with optimal power and the efficiency should be high. An electric motor is a device using electrical energy to produce mechanical energy, nearly always by the interaction of magnetic fields and current-carrying conductors.

SPEED CONTROLLER

The purpose of a motor speed controller is to take a signal representing the demanded speed, and to drive a motor at that speed. The controller may or may not actually measure the speed of the motor.

CHASSIS

The primary challenge in developing an effective solar car chassis is to maximize the strength and safety, but minimize the weight. However, safety is a primary concern and the chassis must meet stringent strength and safety requirements.

BATTERY

Battery is the main power supply of a vehicle. A battery is a device that stores chemical energy and makes it available in an electrical form.

WHEEL

Solar car’s wheel type shows difference according to the car’s type. So there is no standard in choosing wheel selection. Thin wheels are always preferred for the car speed.
