The name modifiers are only relative to others of the same type, in which case Light/Micro/Etc. mean less storage, less mass, and significantly inferior integrity, which are all guaranteed differences from the base part. (Basically, light versions minimize the built-in battery space to lighten the power source--batteries are heavy!--without changing the energy generation functionality. Actually, now that I think of it there's a piece of lore you can find which explains this and more
)
But part-to-part comparisons are different: Rating is the most important at-a-glance value there (and prototypes are better than common parts). If you want to do a quick comparison between the most important attributes of a given set of parts, you don't usually need to open the stats window, just press 'q' (info mode) and compare the numbers in the parts list (on the right). For power sources, energy storage isn't so important unless you're running shields.
I don't remember all (any of...
) the values myself (way too many items!)--when playing I just use whatever power is rated highest and/or gives the most energy for its mass. Although since the introduction of Reinforced power sources, I do like to prefer those when running a super heavy combat build, since they are guaranteed to have massive integrity.
As for the fire delay, the tooltip is something like, 'delay on firing weapon' but that didn't tell me what it actually did.
Hm, the popup text I see is "
This is a direct modifier to the time it takes to fire the weapon. Some weapons are inherently faster or slower to fire." And it's shown as a positive or negative number, so I thought it would be pretty understandable as is, but maybe not if you're coming at it from a position of not yet knowing about volley/firing times? You think the description should be somehow more explicit? I'd like to leave the long explanations to the manual.
I don't think there was anything about that in the manual.
It's described in the "Combat" section of the manual, under "Volley" (the first subsection), and also gets a mention in the previous section on "Time."
