Electrical Power Subsystem

Assembly

A fixed solar array on the Sun-facing bus side, lithium-ion battery, and regulators supplying about 2 kW; the orbit at Sun–Earth L2 has no eclipse, so the battery covers launch and contingencies only. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
