<p>Climate change and global warming
indicate that reducing the use of traditional fossil energy and developing new
renewable energy should be an essential matter. Solar energy has emerged as one
of the renewable energy sources for electricity generation since the late 20<sup>th</sup>
century. One way to utilize solar energy is to collect and convert it into
electricity by solar photovoltaic devices through the photovoltaic effect. Due
to the high cost of photovoltaic modules, it is essential to optimize the
performance of photovoltaic modules by using accurate equivalent circuit models.
Among the available equivalent circuit models, the single diode model is
relatively simple and computationally efficient but would be inaccurate if the
recombination loss were substantial. The double diode model includes more
parameters to represent the recombination loss, so the accuracy improves, but
at the cost of adding more parameters to the model. The primary challenge of
applying the double diode model is obtaining the optimum value for the seven
model parameters with a reasonable computational effort. </p>
<p>The current study investigates the
effect of each term in the double diode model. It then proposes a method to
obtain an initial estimate for each of the seven model parameters from data
provided by the manufacturer. Using these initial estimated parameters as
inputs, the Newton-Raphson method is applied to improve parameter estimates and
prediction accuracy. The performance of two PV modules from different
manufacturers is then modeled using the initial parameter estimates and the
Newton-Raphson updated parameters. Both are compared to the manufacturers’
data. </p>
