In plain terms

The company's first planned project is sized at 200 MW to the grid from a 732-tonne satellite, running nine-tenths of the time over a 20-year life; a later project is 40 times bigger.

The claim as recorded

Virtus Solis's 2024 survey gives its first Lucidus project (Table 1, "Virtus Solis - Project #1") as 200 MW rated to grid from a total mass of 732 metric tons, at an 89% capacity factor producing 1,559,280 MWh a year, over an amortised lifetime of 20 years; its Project #8 is 8,000 MW from 24,513 t.

Scope and limits

THE VENDOR'S OWN FIGURES. SRC-013 is Virtus Solis's survey of its competitors and itself (T4), and states "Data associated with the Virtus Solis system was internally generated" (PDF 2). No held source checks them independently; SRC-076 Table 1 (PDF 12) repeats the 200 MW and 0.27 kW/kg for "Virtus Solis P1" from "manufacturers' claimed values (not independently verified by Frazer-Nash)" (PDF 11). Own arithmetic: 200 MW / 732 t = 0.27 kW/kg; 200 MW x 8,760 h x 0.89 = 1,559,280 MWh, exactly the table's figure. The table's other columns are other organisations' designs as the vendor restates them.
