Solar Accu Ratio changed in 2.0?

[Ich bin ein Otaku]

Hi,

simple Question: Did the ratio of Accumulator to Solar Panel change from the 0.84??

I have 23k Accumulators to 26k Solar Panel . Its a bit more Accus than the optimal, but I noticed that my Solar can charge 100% in half a day while the Accus are drained 90% at night, so my Backup kicks in for 5% charging...

From the Wiki "The optimal ratio is 0.84 (21:25) accumulators per solar panel, and 23.8 solar panels per megawatt required by your factory (this ratio accounts for solar panels needed to charge the accumulators)."

That only applies if you are using 100% of your factory power steady for an entire day cycle. That is never going to happen in practice.

In your case your likely don’t have enough panels to support your factory MW usage

I repeat: My Accumulators are 100% charged in 50% of the time, the other 50% of the day my Solar Panels only produce the consumed electricity. I am 101% sure I have enough Solar Panels.

PS: I dont use Lamps

Also I forgot to mention, you have to multiply your solar power in MW by 0.7 to get the real MW since the solar panels average to 42KW per panel because of dawn and dusk. Or just take all your solar panels (26,000) multiplied by 42KW.

Make sure all your accumulators are actually connected to the same network if you haven’t already and don’t get turned off or disconnected by any circuit logic.

Not mentioned, and perhaps it don't apply, but the ratio is only correct for Nauvis. If it is still correct.

Second consideration: quality. Output of solar panels goes up and capacity of accumulators goes up.

@Mech Read my Question. READ and UNDERSTAND.
@Chin Yes its about Nauvis. I find it strange that my 2 year old blueprint gives me this strange phenomenon.

The power/energy ratings for both remain the same, at normal quality, in the wiki. Since the wiki is updated for the quality values I expect that the normal values would be updated if different. I can't imagine that the wire reach increase of the big poles would make a difference in a solar array. Perhaps, during charge/discharge you can verify that the number of active panels/accums are sane compared to the print's count. The mentioned disconnect "could" happen if there's something which didn't get built because of a cliff corner or a tree the bots forgot to remove.
As an old print you already know 'it works' and what to expect in the graphs. That they don't match expectations becomes interesting.

[Chindraba]

Just a quick check on the construction. Use a decon planner set to delete ghosts and drag that over the array and see if it finds any. The accums charging too fast and discharging too fast does suggest that there are some accums missing somewhere.
Actually, a decon planner set to panels and accums can also be used to count them rather than waiting for the power graph to be at the right points.

The disconnect because of not build powerpoles had me for a sec... but its not possiible because I read the numbers from the Powergraph. It only shows active Components. And I got exaclty one Powerswitch at the far end of my Base, far away from Solar. Used to Connect 800 Steam Eingines

But I got my answer. The ratio did not change.
And it does not really matter, because I can just build more as I already did xD

Thx Chin

[Chindraba]

I was more concerned with un-built accums. A missing power pole would have given an unplugged alert in yellow and you'd have seen that nearly instantly.

A post on the official forms ( https://forums.factorio.com/viewtopic.php?f=18&t=118649 ) says that the day-length on Nauvis has slightly increased, and that therefore you need slightly more accumulators.

Yes, the day night cycle did in fact change, despite all of these posts telling you you are crazy :) It used to be 416.66 seconds, and now it is exactly 420 seconds.

That’s not relevant to the post though. Those 4 second are negligible to the information posted.

There is absolutely no way their accumulators drop to 5% at night yet charge in only half a day if they are actually using the 0.84 ratio. Something is indeed wrong somewhere somehow.

I think my Save is broken... Found another Bug. Ive made some blueprints for rails last week. 100x100 as absolut grid with offset 1 1. Had to play around for 2h until I could rotate the blueprints and still be aligned. Yesterday I wanted to use them and they did not work. And I could not repair them. Lucky I had the old playarea still araund to copy them again and they work again.

BUT now its getting interesting: The old and new blueprints are identical (even the string to copy) but they behave different. New can rotate, while the old will offset by one rail when rotating

...so my Backup kicks in for 5% charging...

I dunno about the solar/accu ratios, but what I do is wire up the burner inserters that feed coal into the steam boilers, and connect them to a nearby accumulator on the power network. My burner inserters will not kick on unless accumulators are below 25% full (pick any number you want for when you want that emergency power plant to come online).

Nutshell: my coal steam engine power plant never comes online unless there actually is an "emergency shortage" of electricity in the grid (by the accumulators going below 25% charge).

Whenever I notice my steam engines coming online, that tells me I don't have enough solar/accumulators to make it through the night:
1. If the accumulators never get fully charged during the day: I need more solar panels panels.
2. If the accumulators are getting fully charged (typically long before night starts): I need more accumulators.

Thats one way to do it. But i prefer a single connection from backup to main grid and a powerswitch with a SR-Latch between. Prevents a massive overproduction of energy with bigger backuppowerplants and gives you the advantage to use storagetanks as powerstorage (1 tank = 150 accu). That way a single Coalbelt can produce much more energy in case of brownout., It can fill the tanks at day when solar is up again.

Its a shame that you cant use electricity to heat water. Would ditch accu completly xD
