Its not exact and it changes as i plop down more every so often.
Efficient solar panel setup factorio.
Adds higher tiers of solar panels and accumulators.
Image credit u deamonengineer probably.
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.
This means one solar panel produces an average of 42 kw over one day and night cycle.
This means that you need 1 428 mw of production of solar panels and 100mj of storage to provide 1 mw of power over one day night cycle.
During daylight hours every panel provides the maximum power level 60kw.
Makes space efficient solar farms viable and reduces the hassle to place as many panels.
Here is a quite popular blueprintable design by madzuri.

Solar panels are an unlimited source of free energy that produce no pollution.
You can always sacrifice a bit of the optimal ratio for a cleaner design but you should stay in the area of 0 8 0 9.
My base will burn through about half of my accumulator charge when it is producing at a moderate clip.
Though in all honesty you probably aren t ready for solar panels yet if the cost bothers you.
As for which to actually pick i d say it s up to your preference cilya s design with accumulators instead of a roboport is the only one with perfect 0 86 ratio among popular designs used by factorio players.
Currently i have 38000 solar panels 31000 accumulators and 1700 steam engines.
My setup uses about 75 solar panels for every accumulator.
