Abstract
A simulation of shading effects in arrays with different string configurations
has been done. Simulation has been performed using as the basic unit
the solar cell, modelled in direct bias by the conventional one exponential
model, and in reverse bias by an equation previously validated in
different types of photovoltaic cells reverse characteristics. The
influence of the amount of shading, the type of reverse characteristic
of the cell, the string length and the number of shaded cells has
been analysed, and some recommendations are extracted.
