An improved and simplified formulation is given for a solar array current-voltage model. This model curve matches a specified maximum power point (i,v) specification, in addition to the open-circuit and short-circuit specifications. The improved model has a simplified numerical solution, which is practical for SPICE simulation of orbital-scale electrical power systems. This paper presents the mathematical development of the solar array model solution, and the form of the necessary Newton/Raphson equations. The iterative nonlinear solution is then realized in a SPICE model of the solar array, which is then demonstrated in an orbital-time-scale satellite power system simulation.
