This paper proposes a new current–voltage ( I – V) modeling approach for photovoltaic arrays based on time warp invariant echo state network (TWIESN). I – V characteristic model of a PV array is not only nonlinear and implicit, but also strictly dependent on material types, manufacturing process, ageing and environmental influence.
