At the "sub-point" of the Sun; when your latitude equals the Sun's declination. The Sun will be straight up at that location.
It depends on the time of year of course.
For example, on the Tropic of Cancer or Tropic of Capricorn this happens at the summer solstice there.
At the equator it happens twice a year, at the equinoxes.
90 degrees.

insolation
intercepted solar or intercepted insolation are part of the sun rays or power that was prevented to reaching solar panel on earth surface, a) dust b) humidity c) cloud d) rain. these factors either disperse or absorb the solar insolation thereby intercepting it reaching the earth surface or the panel.
Polar areas
why is the solar angle a term that refers to the
solar angle is the angle at which a ray of light hits the earth. Beam spreading is how energy is distributed on earth because of solar angle
it decreases steadily
Atmospheric Beam DepletionIs the reduction in the amount of solar insolation as it travels through the atmosphere.when the solar angle is 90 degrees, the solar radiation passes through the atmosphere as directly as possible.
Insolation is a measurement of the solar radiation received by a surface over a unit time. Polar regions have the lowest insolation.
Insolation is intercepted solar radiation.
Solar panels that convert sunlight to electrical energy are an application of insolation.
Local noon.
incoming solar radiation = insolation
insolation
In Earth Science, it means Incoming Solar Radiation.
