generating electricity as efficiently as possible. The MPPTs have to constantly monitor the output of the photovoltaic cells because that output depends on the light intensity which can change rapidly if some cells become shaded. The electricity then flows into the battery where it can be stored for later use such as to drive the car while there is no sunlight. Although the battery is primarily charged by the solar panels, it can also be externally charged by the conventionally generated electricity at your home or workplace. The battery then discharges the current into the motor controllers which converts it into a form that can be used to power the electric motor. Motor controllers are also used to manage things like speed regulation,

VIolet is
Sunswift's first four-seat, four-door vehicle with a 5-square-metre solar array consisting of 318 monocrystalline silicon cells with an approximate efficiency of 22%. VIolet was designed with a greater focus on practicality, with the aim of resembling a more comfortable family vehicle in comparison to previous generations of Sunswift vehicles. New features have been implemented in VIolet such as live monitoring and fault detection, entertainment systems, air conditioning, navigation, wifi, reverse camera, adjustable seating, parking sensors, front and back boot-space, and ergonomic dashboard. As a result of this, the vehicle competed in the 2017
418:. The car cost approximately $ 500,000 and was built to compete in the new Cruiser Class in the WSC. This class focused on more practical solar cars with passenger seats, greater safety and more efficient batteries. To reflect its focus on practicality, the team also designed it to resemble a modern-day sports car, rather than the typical space aged style of most other solar vehicles. The car was the fastest vehicle in the Cruiser Class, achieving Line Honours and overall third place for the Cruiser class while also attaining the highest top speed of 128 kilometres per hour (80 mph).
107:. Regenerative braking is using the existing motors as generators by converting the rotational energy of the wheels back into electrical energy, slowing the car down and recharging the battery at the same time, instead of just using conventional mechanical brakes. Lastly, the energy that was once in the sunlight shining on the car, reaches the electric motors which operate on the principles of electromagnetism to turn that electrical energy into rotational energy that spins the wheels and drives the car forward.

These cars rely on converting the electromagnetic energy of the sun into electrical energy, through the use of photovoltaic cells, and then converting that electrical energy into mechanical energy to drive the car, through the use of some form of electric motor. Maximum power point trackers act as an interface between the solar array and the battery, while motor controllers act as an interface between the battery and the electric motors

On a single charge of its batteries, eVe can travel up to 500 kilometres (310 mi) or over 800 kilometres (500 mi) if powered by its own solar cells. Once fully depleted, the batteries can be completely recharged in 10 hours using a standard household power socket or in under 7 hours using a
