How to Build a Model Solar Car

Solar energy is one of the most efficient sources of energy. Many industries and households are converting their source of energy to solar energy as it saves electricity bills. You only need to install solar panels and then avail its uses.

The solar panels convertĀ  sunlight into electricity. Solar cells collect the energy and transfer into motors or batteries.

Things Required:

– 1/2-inch balsa wood
– Glue
– Drill
– Gears
– Wheels and axles
– Motor
– Wires
– Solar panel
– Card stock
– Switch (optional)
