MAKING A SOLAR POWERED MODEL RACING

CAR

V. Ryan 2006 - 2009

 

A model solar powered racing car can the manufactured from some basic materials and components. These include cheap low powered electric 'solar' motors, straws, card and insulation tape. The most expensive component will be the solar panel, costing approximately ten British Pounds (sixteen US Dollars). A sample model is seen below.

The photovoltaic solar panel produces approximately 2 to 3 volts, easily enough to drive round the 1.5 to 3 volt electric motors. The voltage produced depends on the intensity of sunlight.

   

Photovoltaic panels convert the sunlight directly into electricity. A typical example of a device powered by photovoltaic cells is a solar powered calculator. This type of device only needs a small amount of electrical power to work and can even be used in a room with artificial light (bulbs / fluorescent light). The panels required for a powered model vehicle are much larger but can be purchases cheaply as solar power kits, for children to use.
