Description
The
software will compute the sun's Azimuth and Altitude as a
function of the time, date and location. Azimuth is the compass
direction of the sun in degrees with 0 degrees aligned with North
increasing clockwise. The Altitude is the elevation of the sun
above horizon in degrees with 0 degrees being the horizon. From
the sun's position the Air Mass and the total direct solar
irradiance incident on the earth's surface is derived. In the
clock mode calculations will be done according to the actual day
time. In the calculator mode the total solar energy which has
arrived on the earth's surface between two dates will be
calculated.
You can find a nice illustrated explaination of the basic definitions in the article of V. Quaschning in the internet.
Some experiments with photovoltaic solar panels which illustrate the influence of the panel's orientation towards the light source on the outputted electricity are described here.
