Sun light is is the result of micromass radiation which emergerges out of Sun's atomic Nuclear fusion.
Weight relates to a gravity force measured in Newton.
Light is basically a flux of microparticles.The weight of these particles can be measured as they collide with a surface of a material.
The mass of one light particle is in the order of 10^-51 kilogram. That is a small mass which is one kilogram divided by 10 followed by 50 zeros.
So mass of light per Unit is nearly zero but never zero.

Dude, sunlight doesn't weigh anything! It is an electromagnetic wave, it's not matter. I'm assuming you're really young, that's why I'm not going into complications regarding light's dual nature (it behaves like matter in some cases too, but you can't put it on a weighing machine and check the result!! It's in a more complex fashion.. The best I can do is tell you that light has momentum)

Sunlight, composed of photons reaching the earth, has no weight. It has
energy, but from the equation E=mc2, an equivalent mass to this energy can
be found. This, however, does not mean that the mass of the earth increases.

Matter has properties of mass, weight, density, and volume.
Energy is the ability to do work or to cause change.
Since Sunlight is a form of energy not matter, it cannot have weight.

Exactly the same as any other kind oof light...... Nothing. Photons are massless.
