Because it cost way to much money fr people to afford
The "solar system" comprises the Sun and all its orbiting planets. The solar system can not be used to heat cars and homes, your question is meaningless.
it depends on if it's for cars or homes,but in general it will be because the sun is inexhaustible
...cuz they run on solar energy? lol
At the current time the installation of solar panels to create energy is expensive and it takes a number of years to save money from it. However many people have begun using it in the home. In Israel most homes have solar heated water, and their are two companies working on creating a country wide system for solar charged electric cars.
Solar cars refuel just by regaining energy from the sun. They use all of that energy to create fuel in order to run. Some solar cars refuel by using wind energy! Solar cars gain energy from the sun or from the wind to store the energy in their fuel tanks and they use up the energy to make fuel that allows them to travel for long distances! Solar cars have no limits on how many times they can regain energy from the sun or from the wind!
cars
By using solar energy to charge the batteries
solar cars get energy from the sun and transfur it in to electricity gas cars burn gas to make electricity
Not many cars operate on solar energy, I doubt if it will catch on
Solar energy saves you money.
if they make solar cars than yes :)
No because they are powered by solar energy! Hence the name 'Solar Car'
