I believe every inch of area under a solar panel or accumulator to be covered is necessary if you want to tile the array because substations only connect at their coverage boundaries.
Solar panel array factorio.
0 84 can be obtained by having one array with this modification per 309 134 2 306 arrays overall 175 modified arrays per 134 arrays with the op s layout while having one modified array per pair of arrays yields a ratio of 0 836 at an average of 8 275mw per array.
If one replaces a 3x3 block of accumulators in a bit more than half of their arrays with panels one can get closer to the ideal ratio.
During daylight hours every panel provides the maximum power level 60kw.
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.
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.
Generated power will increase decrease linearly during dusk and dawn and no power is produced at night.
However i sort of concede that it is possible however the alignment of solar panels in the manor you suggest would actually waste more space than gained.
This means one solar panel produces an average of 42 kw over one day and night cycle.
Solar panels are an unlimited source of free energy that produce no pollution.
