This highly abstracted Sandia Lab model will give us a good estimate of the expected output of your array, under the current environmental condition.
φ - incidence angle between the array and the position of the sun.
S - irradiance.
D - panel efficiency, usually between 14 to 18 percent.
T - temperature of the panel.
Area - total area of the array.
