UPDATE: My new solar arrays blueprint book has a new solar array that is slightly more compact/efficient than this design. https://factorioprints.com/view/-Mb-8ayzNVvhbV3UmGwa
Compact Solar Array
This is a compact solar array that includes roboport and radar coverage. This is one of the most efficient tileable solar arrays of reasonable size (7 x 7 chunks or smaller) with roboport and radar coverage in terms of power per area.
This blueprint can tile horizontally, vertically, and/or diagonally. When building over water, it is highly recommended to place landfill by hand.
198 x 199 tiles
131.49 MW net sustained
0.840382 ratio
299.658 tiles / MW (2nd best/lowest ever <sup>1</sup>)
Entity Count <sup>2</sup>
- 3145 solar panels
- 2643 accumulators
- 102 substations
- 6 roboports
- 1 radar
<sup>1</sup> Formerly the lowest tiles / MW number of any tileable solar array with full radar and roboports construction coverage of tile size 224 x 224 tiles or under. My Solar Arrays Book includes a 198 x 200-tile design with a slightly lower number, and I have a 198 x 199-tile design (not shared) with a slightly lower number than this design, but higher than the 198 x 200-tile design.
<sup>2</sup> Substation, roboport, and radar counts only apply when blueprint is tiled in all 8 directions
