Quick and Accurate Strategy for Calculating the Solutions of the Photovoltaic Single-Diode Model Equation
The photovoltaic (PV) single-diode model is the most
widely used to characterize the behavior of a PV panel because it
combines high precision with moderate difficulty. Lots of methods
to obtain the model parameters use optimization techniques that
require the resolution of the characteristic equation thousands of
times; therefore, it is essential to calculate its solutions accurately
but also in the shortest possible time. The objective of this article
is to describe a new numerical strategy to solve the characteristic
equation in a simple, fast and precise way. The main idea is based
on a reparameterization of the Lambert equation which is closely
related with the infinite power tower, and some well-known bounds
of this tower will be used as seeds of numerical methods. This
strategy is powerful for certain “small” values of the Lambert W
function argument, but it is combined with another re-expression
of the Lambert equation for the remaining “large” values. The
proposed numerical strategy is so precise in very few iterations
that it can be suitably transformed into an explicit formula. The
results obtained have been compared with some of the best options
in the literature and expexperimental results prove the power of the
proposed methodolog
