sigh

Hi all I have a load profile, in 30 min intervals. I am required to design a: 1.Grid connected system 2. Grid connected system with battery 3.Off grid system I am truly new to all this and having a really tough time. Please can someone share how does one verify that the system size covers the load for these three designs? Example: for grid connected, that my day load load is covered by the system. I am using PVsyst trial version Thank you in advance for any and all help or suggestions
