Estimates range from as much as 50 million years to as little as 17,000 years.

According to a Horizon program I saw, it takes thousands of years for the light and heat generated at the core to reach the surface. This is due to the intense pressures at the core.

I've always heard around a half-million years. And it's because the photons which carry all of that energy are reflected off of other particles in the Suns core (which is unbelievably dense)

I have heard that it takes millions of years. That could be true only if there were not a convection all the way between the core and the surface, which would obviously move it a lot faster.

Distance from the earth to the sun is about 1.5x10^11 metres. The speed of light is about 3x10^8 m/s. Heat travels at the speed of light hence that works out to be 500 seconds, or 8 minutes, 20 seconds for the heat to reach earth frm sun.

It takes various thousand years from the ability created in the fusion reactions in the middle emigrate to the outer floor of the sunlight. From there the electromagnetic radiation travels on the fee of sunshine by area.

According to the wikipedia article, estimates range from 17,000 years to 50 million years! Wow.
