Scientific revelations:

A solar car is a kind of car driven by solar energy. Compared to conventional heat-powered cars, solar cars are truly zero-emissions. Because of its characteristics, solar cars are promoted by many, the development of solar car industry is also increasingly vigorous.

Scientific production:

1, recognize and prepare the materials needed for the experiment.

2, step by step against the instruction manual steps to progress installation.

3, the installation is complete for debugging.

Scientific principles:

The energy of sunlight passes through the solar panels and is converted into electric current, which flows through the motor, causing it to rotate, generating mechanical energy that drives the wheels to rotate and the car to move forward. Solar panels do not store solar energy, but convert it into electricity in real time. When there is no sun, the car stops, and the battery can be used as power.

Scientific expansion:

In a sense, solar cars are also a kind of electric vehicle, the difference is that the battery of electric vehicles is charged by the industrial grid, while solar cars use solar cells. Solar cars use solar cells to convert light into electricity, which is stored in storage cells to power the car's electric motors. Since solar cars don't burn fossil fuels, they don't release harmful substances. It is estimated that if solar-powered cars were replaced, CO2 emissions per vehicle could be reduced by 43 to 54 per cent.

A cellular device with dense hemp on a solar car is a solar panel. Solar cells are divided into silicon batteries, cadmium sulfide batteries, gallium arsenide batteries, etc., which are commonly used in silicon solar cells. In the sun, solar photovoltaic panels collect sunlight and generate a common current. This energy is stored by the battery and provides power for future travel. Or directly to the engine can also be open side storage. Energy drives the wheels through the engine controller, pushing the solar car forward. And without an internal combustion engine, solar-powered electric cars can't hear the roar of the fuel-powered car's internal combustion engine while driving.
