Around 8minutes 20seconds. A few seconds more or a few seconds less, depending on the Earth's exact distance from the sun during the year.

Solar energy reaches the earth by two means, Electricity and Gravity.
Since ultraviolet radiation from the sun does have to travel through outer space in order to reach the Earth, you could say that it comes from space, and therefore the ozone layer which protects against solar ultraviolet radiation is a kind of space shield.
Waves of heat and light, called radiation, travel to earth.

gamma radiation
Gamma rays are a form of electromagnetic radiation, and thus they travel at the speed of light. If a star is one light year away, it will reach Earth in one year.
Electro-magnetic radiation (sunlight).
Stars don't travel to earth. But the light and other radiation that they emit spreads out in every direction from the star, and some of it eventually hits the earth. Starting out from the star, it takes the light 1 year to reach the earth for every 5,878,700,000,000 miles it has to cover to get here.

As the sun's rays heat up the earth, the radiation hits the atmosphere. Then the radiation heads back to the sun.

The space shuttle reaches 17,850 mph before leaving earth's atmosphere.
