How many batteries per Solarpanel?

[Lapiro]

Hello,

I have at the moment a big stream problem, because my batteries are not sufficient. Gibts then an approximate rule of thumb how many batteries I should build per Solarpanel?

Greetings,

I used to have a plan that 16 solar panels to 12 accumulators. That was pretty close (4:3) to the ratio they recommend.

In general, just do a bit more solar than accumulators and you should be fine.

Also remeber that each accumulator has a maximum power output. If you can't supply enough total power for your base then you will suffer brownouts regardless of the ratio.

True, but it's highly unlikely someone would rely on accumulators for power during the night, and wouldn't have enough accumulators that the discharge limit is reached. The bigger your base, the more solar/accumulator fields you need to power it, the more accumulators you have in parallel giving you a massive accumulator throughput when it is demanded.

Well, for pure solar with accu for night storage, you need 0.84 accu per panel.

Which is very close to 5x accumulators per 6x solar panels.

Thank u for this information, now i try something :)

Thx for all your help, have a nice day!

It's actually 0.84 accumulators for every solar panel.

Batteries are cheap,so a 1:1 ratio would be fine

Hallo, my Batteries are not loading at full capacity.

batteries should be able to use much more energie for loading than the few MW, it did work at first and than something changed.

You only have 5MW to spare, if you add up the rest of the power usage. At that rate it will take 30 minutes of full sun to charge those accumulators.

With that power usage (75MW) you need at least 1786 solar panels (42kW per panel effective) to supply enough power for both the base and to charge the accumulators to a level that will keep the base going through the night.

i see, the max possible production of power is taking the max possible output from the batteries into the counting. confusing

A quick tip, if using solar and using at least the standard 0.84 ratio.

When you view the Power stats, switch to 10 mins view, as this shows a full day and night cycle (slightly longer actually).

What you should see as the sun comes up, solar panel output increases, and the accumulators start being charged. Once the Sun is fully up, solar should run at 100% for a while till the accumulators are fully charged.

Then you should see a sudden drop from 100% solar panel output (while charging accumulators) to a much lower level (typically 50-75% output), which is what's needed to keep the base going during the day.

Then as the sun goes down, solar output drops, and the accumulators take over for the night, discharging.

The key thing to look at, is when does the sudden drop from 100% solar panel output happen? (i.e. when do the accumulators hit 100% charged?).

• If this is early in the day, then you've too much solar currently (or you just planned ahead :-) ). So you are good to go.
  
• If this is in the middle of the day, then you've still got some headroom to expand the base before needing more power.
  
• If this is very late in the day, i.e. just before night fall, then you really need to expand your power before expanding the factory further.
  
• If solar output never drops from 100% before night fall, (i.e. the accumulators never hit 100% charged). Then you don't have enough solar in place, and will most likely have blackouts at night, so you need to expand power urgently.

Additionally, if your ratio is wrong, and you don't have enough accumulators, then you might find you hit 100% accumulator charge at a good spot early in the day, but then run out of power during the night anyway. In which case you need more accumulators.
