Amount of solar energy per day in a given location

  1. Hi,
    I'm trying to find equation for an amount of solar energy that given place (of some latitude) on Earth's surface receives during a given day. I know it can be derived by using basic geometry, but I just need it for some application and don't want to waste time and risk mistakes. So if you know, where I could find this, I would greatly appreciate a reference. Thanks in advance for any help.

    That is impossible to calculate.
    The amount of solar energy reaching the Earth depends on many factors. Think about clouds.
  4. My mistake, sorry for not specifying the question more accurately. You can assume that solar output is perfectly homogenous, constant, Earth is a perfect spehere with no atmosphere. Basically I'm just interested in the effect of varying angle from which you can see the Sun from that place.
