[Spaceships] Alternate System Usage Questions

[Varyon]

Vehicles had a retractable panel for mounting solar cells be double weight and cost. Note this is double cost and weight for the panel, not the cells. I've been working on adapting Vehicles for use in Spaceships (and throwing out abstract PP in favor of kW/ton in the process), and what I worked out there was that simply doubling the cost of the entire solar panel assembly (no change in weight or output) is sufficient to make it retractable (by using more expensive materials for the panel if it's made retractable).
