A Simple and Efficient MPPT Method for Low-Power PV Cells

Figure 3

Computed 𝑉_MPP versus 𝑉_OC for a single PV cell. Two least-square regression lines are also represented: the grey line corresponds to the FOCV method with 𝑘=0.809 whereas the black line corresponds to the LOCV method with 𝑎=0.894 and 𝑏=−0.041. The parameters of the PV cell model are 𝑇_a=25^∘C, 𝑛_d=1.5, 𝑅_s=0, and 𝑅_p=∞.
