why are manucturer not putting solar energy in the all transportation so we don’t rely on gasoline?

we need to think of other sources to power our vehicle. I think solar panel should be place in car, place, boats, train, etc.

Two clear reasons (for cars).

1. It is not commercially viable.
2. It is not and probably never well be technically viable.

1) Commerce.

As those posting before me rightly explain, solar cells are very expensive, and the prototype cars built by Honda to carry just one person with no luggage at speeds of upto 50mph cost over a million dollars to build.

2) Technical Limits.

A family car today uses about 30 Kilowatts of energy (the same as 15 hairdryers) and needs this much to haul you and your luggage about.

As a poster above has pointed out, solar cells only convert about 20% of sunlight to electricity, but on top of that, only about 1Kw of sunlight falls on every square metre….

What this means is, with present technology, a family car would need a 150 Square Metre solar sail to supply it enough power to move, in full sunlight on a clear day. Which isnt really very practical as the roof size of a typical car is only 4-5 square metres.

The situation for boats and trains is no better.

Solar power is a good solution for things like heating water or supplying electricity to your home, but for powering cars and the like, there just isn’t enough energy in the sun to make it work for the types of cars most of us drive (i.e. that carry several people and luggage). And a prototype vehicle that can do 50mph carrying one (slim) person and no luggage can only reach 40-50mph on the flat, and costs over $1,000,000 to build.
