So do you think the solar panel is overpowered after crafting them? Do you think they were worth the effort of making?
They are a HUGE pain to craft but even with that, I am now charging a MSFU as fast as it can decharge, and its on the the set it and forget setups. I would suggest keep the crafting the way it is and reduce the daytime EU output down to 4 (keep the night time 1/eu). At that point they are still awesome to have but its not an item that is a "must" early on but you would sometime or another make a few even if its just for your remote off the wall bases that dont need a lot of power.
Edit: On a side note you could make these items even more "endgame" by adding Iridium plates into the crafting recipe. THAT would have stopped me from making a whole stack because I do not have enough plates on this map yet,
