i think you understand me wrong.
the problem is that the solar panels that you need to craft it produce 4800kw and the bio solar farm produce 2000kw so it would not make sense to craft one at the moment
another think would be to change the recipe to 5 solar panels mk3 (from 20
oh and the reason why 50% is:
large solar mk1 106kw > large solar mk2 160kw > large solar mk3 240kw
and i see the bio solar farm as mk4
