Design Architecture

Solar panels configured to defined dimensional, electrical, and environmental constraints.

Panel geometry, substrate architecture, encapsulation, and electrical interfaces are defined by system requirements. Thin-film and crystalline platforms support distinct integration strategies based on performance and environmental constraints.

 

Geometry & Form Factor

Panel geometry is defined by enclosure and mechanical integration requirements, not standard formats.

  • Panel area: From sub-1 sq in modules to multi-panel assemblies.

  • Custom outlines: Cutouts, notches, radii, segmented geometries.

  • Edge definition: Laser-cut dimensional control.

  • Fold sections: Defined hinge zones for deployable formats.

  • Tab extensions: Mounting or electrical routing interfaces.

  • Tolerance control: Verified against mating component stack-ups.

Geometry is validated against system-level requirements.

Substrate Architecture

Substrate selection depends on cell technology and defines rigidity, flexibility, and integration method.

Fabric Substrates (Wearable & Portable Systems)

  • Polyester (200–1000 denier): Flexible structural backing.

  • DWR coatings: Moisture resistance.

  • Ripstop / PVC-coated options: Enhanced tear resistance.

  • Lamination compatibility: Withstands 150°C processing.

Metal Substrates (Rigid Integration)

  • Aluminum backing: Structural rigidity.

  • Stainless steel: Corrosion resistance.

  • Direct fastener compatibility: Mechanical mounting interface.

Fiberglass

  • Electrically insulating: Non-conductive support.

  • Dimensional stability: Reduced thermal distortion.

Plastics & Laminates

  • Tuned flexibility: Controlled bend characteristics.

  • Low mass: Weight-sensitive systems.

Substrate selection defines mechanical behavior and installation method.

Encapsulation Strategy

Encapsulation defines environmental durability and flex performance.

  • Thickness range: 0.22–0.5 mm.

  • UV-stable films: Outdoor exposure compatibility.

  • Moisture barrier layers: Optional sealed configurations.

  • Minimum bend radius: Defined by cell technology and substrate.

  • Repetitive flex performance: Evaluated per construction profile.

  • Lamination profile: Tuned for stiffness or flexibility.

Encapsulation may be reduced or eliminated for controlled indoor environments.

Protection level is engineered to exposure profile.

Electrical & Mechanical Integration

Electrical Interface

  • Custom wire leads: Length, gauge, and exit location.

  • Backside contacts: Laser-defined pad access.

  • Extended bus bars: Post-lamination connectivity.

  • Solderable pads: Standard PCB assembly compatibility.

  • Conductive adhesive interfaces: Epoxy or z-axis bonding.

  • Charge controller integration: Aligned with battery chemistry and load profile.

  • Custom cable assemblies: Built-to-spec wiring harnesses and connector integration.

Mechanical Mounting

  • Adhesive bonding: Acrylic, VHB, butyl.

  • Mechanical fastening: Rivets, screws, grommets.

  • Lamination integration: Plastics, metals, composites.

Integration architecture is defined by system requirements.
