Light is the main kind of solar radiation. Yes, I mean plain old visible light. There is also infrared light, which is heat, and ultraviolet light, which causes suntans and sunburns. The sun also emits gamma rays, which are just very short wavelength light, and particles, like electrons and other subatomic particles. Most of this, except for the visible light and some of the infrared light, gets filtered out by the atmosphere or the Earth's magnetic field before reaching the ground.

Solar radiation is radiant energy emitted by the sun, particularly electromagnetic energy. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum. The other half is mostly in the near-infrared part, with some in the ultraviolet part of the spectrum [1]. The portion of this ultraviolet radiation that is not absorbed by the atmosphere produces a suntan or a sunburn on people who have been in sunlight for extended periods of time.
Solar radiation is commonly measured with a pyranometer or pyrheliometer.
