Description: The flexible photovoltaic (PV) modules have the advantage
of easily fitting on curved surfaces, but in that case their
power–voltage characteristic exhibits localmaximum power points
(MPPs) where the PV module power production is suboptimal.
In this paper, the effect of geometrical installation parameters of
flexible PV modules, such as the bending angle, tilt angle, and
orientation, on the shape of the power–voltage characteristic is
experimentally investigated. Then, a new method of tracking the
global MPP of flexible PV modules is proposed. An experimental,
comparative study is also presented, which demonstrates that compared
to the past-proposed MPP tracking (MPPT) techniques, the
system proposed in this paper is capable to detect the global MPP
of a flexible PV module with less search steps. Thus, the power
loss during the global MPPT process is minimized and the energy
production of the flexible PV module is maximized.
