Understanding how a solar panel works in the real world.

Equivalent circuit equation for a solar cell, or a solar panel.
A solar panel is just a number (N) of cells in series.

I = Iph - Io(e^(q(V+I*Rs)/aNkT)-1) - (V+I*Rs)/Rsh

Iph = ideal current source, which  value is linearly proportional to the solar energy  watts/m^2 

Io = Is a cubic function of Temperature.
