PV array with boost converter

Hi!I try to design a system in which a DC machine is powered by a PV array, using at the same time an MPPT algorithm (P & O). The problem is when I use the PV array I designed, everything goes wrong and I cannot fix it , because I am a beginner in simulink. I think that something is wrong with my PV array. Can anyone correct my mistakes or give me some advice? Every help is appereciated!
