The solar matrix core is located within the Spear of Adun. It is the central power core for the arkship, and provides power for the subsystems and nutrients for all protoss on board. Inside it is a synthetic star powered by the rare but highly exothermic material named solarite. Because of its long dormancy, it didn't initially have the energy required to fully power the arkship's weapon and defense systems. However, Phasesmith Karax was able to familiarize himself with the core's technology, and slowly bring the systems back online.
As the player collects solarite for completing optional objectives, the solar core's power output rises and the player can activate more abilities at a time. Solarite not being used to activate abilities can be diverted to the auxiliary systems, which are divided into three categories: raising the regen rate of shields, lowering construction rate of buildings, and raising the initial supply the player has on each mission.
Every five units of solarite diverted to one of these auxiliary systems gives a 5% bonus to it, to a maximum of 20% with twenty solarite allocated. After all bonus objectives are complete before the final Aiur levels, a maximum of 300 solarite can be allocated between abilities and auxiliary systems, but this will not be enough to activate the most expensive options for all six systems and fully increase the auxiliary systems as well, so the player will have to choose very carefully based on their preferred tactics.
