Equipment grid question

[Xyteno Sane]

new to the game and just crafted for the first time an armor with an equipment grid and i wanted to know if the effects of the things placed in the grid like the wearable solar pannels or the energy sheild stack. what i mean is if i wear two energy sheilds will i have more armor then if i wore only 1?

They add together, yes. Though 2 night vision goggles or 2 belt immunity equipment don't provide extra effects.

yeah i figured for the belts and all.

how about the modules you put in production building do they stack?

They do.
Only with efficiency modules can you hit a hard limit, can't drop below 20% energy consumption.

Well... there's a hard limit of 300% productivity too, you may never see that. But it's there, so maybe.

Some do some have soft or hard caps. Efficiency modules for example have a maximum total power reduction of 80%. There are caps on productivity bonuses but its pretty hard to reach those caps. Speed stacking changed a bit with 2.0 if you want the 411 you can find it here:

and more exoskeletons do make you run faster and more roboports extend your construction range and the number of bots you can control.

maybe i don't understand something but i think my personal battery isin't working. i have equipped nightvision goggles, energy sheild, personal battery, portable solar panel and belt immunity all one time. however currently my sheild is powered up but i haven't taken damage since i got it so i have no idea it it will recharge when i get hit, my belt imunity is not powered, my battery is not powered and while my night vision is powered it just turns on and then off when it runs out of power but my understanding was that my solar panelwould during the day fill up the battery and at night the battery would power the rest so it can keep working at night but the battery is not charging and i don't understand why.

The solar panels don't produce a lot of power. Have 10-15 of those and you should see a difference. The belt immunity thing alone drains more than the equivalent of 3 solar panels worth when active.

i see that it says the solar pannels produce 30kw while belt immunity consumes 100kw so does that mean that basically i need to putt together the max consumption of all the things i have equipped and have as many solar panel to produce that? for exemple if my max consumption is 300kw i would need 10 solar panels? it may seem like an obvious thing but i am an idiot so. also if that is the case how many batteries do i need depending on what i have.

Huh, yes, and no?
Things like shields drain a lot of power when they have to recharge, but once recharged they don't use any power.

Other than that the best example I could give you is the belt immunity device. It uses 100 kW when active. So if you wanted to stand on a moving belt 24/7, 3 solar panels producing 30 kW each would not be enough. But then you'd realise even 4 are not enough, your battery would totally drain before the end of the night. You have to take into account that because of the day and night cycle, the solar panels only average 21 kW (30 kW -30%) on a full day cycle, so if you want 100 kW 24/7, you need 5 panels.

Personally, I don't see a real need for math in this case. Adjust as you go. Never have enough power for a whole night? Add batteries. Batteries never fully recharge? Add panels. Still won't work? Remove something that consumes power. You can't break this down too well anyway, you'll have periods where you're not using shield, others where you are recharging your shields a lot.

Just eyeball it, adjust, it'll work good enough, imo.

Edit: the -30% power production loss due to night (on Nauvis) was true before 2.0. I've read some players asking if that changed since. Maybe it has, idk, never bothered to verify that. But it should be close to -30%, if not still exactly -30%.

You CAN hit these in the endgame megabase phase of the game.

Average solar panel power is always 70% of nominal peak power, on all planets, because that fraction follows just from the shape of the day-night curve, regardless of the length of the day or the solar illumination strength.

I know, but what proportion of players will go megabase in SA?
Hence the "you may never see that", if OP is part of the majority. ;)

I think you should run tests on other planets. You might be surprised.

I might be, but I doubt it. I don't know what mods can do in this regard, but in the standard SA data files, all the planets just specify the overall cycle length

surface_properties["day-night-cycle"]

. None of them change the fraction of each cycle spent in day, twilight and night.
