Solar panel for Solar Power Manager 5V (DFR0559)

Hello,
The Solar Power Manager 5V (DFR0559) page (https://www.dfrobot.com/product-1712.html) suggests to use this solar panel (FIT0601, https://www.dfrobot.com/product-1774.html). And the product page of the solar panel says also that “it will be particularly efficient when paired with the DFRobot solar power management board” (linking to DFR0559).
So I understand that these two products can work together.
However, it is written in the DFR0559 wiki that “Any kinds of panel (monocrystal, polycrystal, thin flim) can be employed as long as the open circuit voltage is less than 6.5V”. But the specifications of FIT0601 say: “Open-circuit Voltage: 7.2V”.
So, did I miss something ? Can these two products really work together ?
Thanks in advance,
Nicolas
