B01Solar arrays

Generate electrical power from sunlight.

Manufacturers & products

Solar power is a chain of distinct purchases: semiconductor cells, interconnected cells with coverglass, populated panels, and complete deployable wings. The providers below cover each level; a cell vendor is not automatically the supplier of the wing, hinge or drive.

These are sourcing candidates, not a confirmed Starlink supply chain.

manufacturer

Rocket Lab (SolAero)

STARRAY wings; populated panels and solar cells

Supplies cells and panel assemblies, with STARRAY providing a more complete deployable-wing purchase. Panel-only and turnkey-wing scopes should be quoted separately. [1][2]

Manufacturer inquiry

Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.

Product scope & qualifications

The standard families span configurations; maximum family power is not the output of every wing.

manufacturer

Spectrolab

Space cells, CICs and bonded panels

Manufactures photovoltaic cells and CICs and bonds them into panels using customer-furnished substrates. This is a different procurement boundary from a deployment-ready wing. [3][4]

Company location: United States

Manufacturer inquiry

Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.

Product scope & qualifications

Panel service does not establish that deployment mechanisms or solar-array drives are included.

manufacturer

Redwire

Rigid-panel solar arrays

Offers engineered rigid-panel arrays, accommodating different cell sources and tailored structures and mechanisms. This is an array-integration option rather than a claim that Redwire fabricates every cell. [7]

Manufacturer inquiry

Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.

Product scope & qualifications

Family capability ranges are not a fixed model specification; request the current flight configuration.

DHV Technology

Small-satellite solar panels

Designs and manufactures body-mounted and deployable panels for small satellites, with custom electrical and structural configurations. The company also offers associated power electronics. [8]

Manufacturer inquiry

Manufacturer inquiry

Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.

Product scope & qualifications

BOL/EOL efficiency values on a panel page must not be treated as complete-array efficiency without definitions.

Company location: Lithuania / United States

Manufacturer inquiry

Manufacturer inquiry is the apparent ordering route; confirm configuration, quotation and availability directly.

Product scope & qualifications

Company locations do not identify the manufacturing location of a particular panel order.

View product & inquiry route

What remains unverified

This research does not establish the actual solar-cell or array supplier for SpaceX V2 Mini. No listed company is labelled a Starlink supplier on the basis of product similarity.
Most current EOL curves and qualification reports require a configuration-specific inquiry.
Public pages do not always state irradiance and temperature for headline panel wattage. Missing conditions are retained rather than assumed.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Deliverable boundary
Identify whether the quote includes cells, CICs, panels, hinges, release devices, harness and solar-array drive.
End-of-life power · W at EOL
Compare power at the same orbit, mission duration, radiation, temperature and pointing assumptions.
Electrical operating point · V, A
Match hot/cold I–V curves and string voltage to the PCDU MPPT window, including open-circuit limits.
Cell versus array efficiency · % at stated conditions
Cell efficiency excludes panel packing, interconnect, shadowing and power-processing losses.
Mass and deployed area · kg, m²
Use complete-wing mass and deployed geometry; panel-only mass omits mechanisms and harness.
Stowed envelope and deployment · mm, Hz
Check launch fit, release loads, deployed stiffness, damping and deployment test evidence.
Environment and life
Ask for radiation degradation, atomic-oxygen, thermal-cycle and contamination evidence for the intended orbit.
Production and interfaces
Confirm cell source, string redundancy, connectors, traceability and changes required to adapt a catalog wing.

Selection & integration notes

For the large flat-panel communications satellite, shortlist array-level suppliers first; CubeSat panels are useful scale references, not demonstrated replacements for its complete power system.
Request an EOL energy budget covering payload duty cycle, eclipses, battery recharge and propulsion operation before picking area or nominal wattage.
CIC means a cell with interconnects and coverglass. A complete panel still may exclude deployment hardware.
