# Solar Arrays Blueprint Book
This blueprint book provides four solar array designs with a variety of features. This book includes an easy-to-build 3 x 3 chunk-aligned design, a design with the highest area efficiency of any solar array with roboport and radar coverage ever made, a 3 x 3 chunk-aligned design with a higher accumulator-to-panel ratio to deliver burst power for longer, and a 3 x 3 chunk-aligned design with a lower accumulator-to-panel ratio to deliver higher average power output.
### Included Features
* Roboport coverage
* Radar coverage
* 8-directional tiling with grid snap, including diagonals
* No Spidertron necessary (place from map once and done, except when building over water)
* Built-in landfill 1
1 It is recommended to place landfill by hand to reduce build time. Construction bots might not always complete landfill when building the Large Solar Array.
