Solar Power for Spacecraft

We build panels for solar arrays and can mass produce them as well. We also build wings, deployable booms, and more. Our capability is unique – we can do constellation-level production!


Rock West can also supplement with our STRATO Substrate™ product line to reduce lead times with solar array substrate panels that can meet LEO, GEO, lunar, and deep space environments.

Solar Panels

RWC can manufacture laminate and sandwich panel solar array substrates to custom specifications or using our STRATO™ product line. Our stand alone panels with inserts and co-cured kapton layer will complement your solar power assembly.

We can also work with a variety of custom requests. Read more about the hardware shown here in our press release RWC Delivers SAS Panels for 500-Watt Arrays.

Solar Array Wings

We manufacture sets of solar array panels and can build them into a deployable solar array wings. We have experience with constellation level production including 38 plus satellites. Our team excels at precision assembly and match bonding of cup/cone fittings.
