Oscillation in simple PV circuit

Hi.

I build a simple PV system. Basically, A pv and MPPT-drived boost converter. But there is an oscillation in the current and so power signal. I can't undertand why.

There is no control implemented for the Boost converter as it is (no voltage feedback and no inductor current feedback). Connecting the MPPT directly to the switch will not work. Check out this example to learn more about solar PV system with MPPT using Boost converter:
