Storing Power Issue

So I'm trying to figure this out  i have solar energy / coal generator and a energy storage unit

but the issue i have is multiple solar panels share the same power  same as the coal gen 

so if i have 2 coal gens down they both have the same power in it same with solar they share between them 

is there a way where each individual solar has its own energy gain with a limit? i know how to max the limit but its shearing 

as my next step is making wires to transfer power but i don't want the solar's shearing with each other or the coal gens
