Are you okay with these solar panels? (total area = 32.943 m^2)
I think that they provide enough power for the module's necessary systems.

Too close to the module and too wide. Give them a bit more distance and make them longer, otherwise, as you can quickly imagine, a bigger area of the panel would be in the shadow of the module in many angles.

32 square meters of solar array means only 15 KW peak electricity at Beginning-of-Mission (BOM), in LEO about 6 kW available as orbit average (rest goes into charging/discharging batteries), and much less after some years in space.

That is enough for a single module, but pretty annoying if you want to connect more payloads without additional solar arrays.

If you plan for longer operations, make the solar arrays exchangable or removable by EVA. And add powered grappling fixtures for adding a robot arm to the station. ;)

If you also want to save game money ;), better construct the solar array of PV modules that you can reuse for other station modules as well.

I already did. There's one at the front/top.

That is just an unpowered one, the powered ones also have additional connectors around its circumference for powering a robot arm and controlling it.

Also, you should then have more than just one on such a large module, so the robot arm can "walk" to a new position for work.

Are you talking about the one that's circled? Do I only need to add just that?
That's the RMS alignment target. The connector sockets are hidden by the four grey rectangles around the central grappling pin/cams.

And would it be fine if it didn't have those things?
No as those provide the power/data/video interfaces for the SSRMS.

Here's a schematic that explains the various components of the Power Data Grapple Fixture (PDGF):

Actually, this module is not intended to be launched with a space shuttle. It will be launched with a Neptune-1b, and an arm will be attached to OSOI in a prior mission.
SSRMS is the acronym for Space Station Remote Manipulator System. SRMS is the acronym for Shuttle Remote Manipulator System.

The picture is just a grapple fixture. For a Space Station, data transfer is everything, so a PDGF is very important...

Yes. That is a Flight Releasable Grapple Fixture (FRGF).

Yes. If you plan to operate a robot arm with the GF as base, you need a PDGF there. The robot arm can grapple anything with a GF, powered or not, but it can only get power and commands from a PDGF.

A single FRGF is enough for installing the module by a robot arm, but if you plan to work with a robot arm around the module, you need at least one PDGF, better more, at places where the robot arm also has a bigger range and a stable base.

You can consider the PDGF some kind of standard for large robot arms now, the alternatives are for much smaller robot arms.
