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.
