Solar & Energy Storage

Solar hardware Pain Points

Outdoor housings failing from UV exposure, heat, moisture, and thermal cycling.
Increasing need for UL94 V‑0 flame‑retardancy in inverters and BESS systems.
OEM pressure to integrate post‑consumer recycled (PCR) content without compromising performance.
Delays from offshore tooling and slow iteration cycles.
Over‑engineered housings with too many fasteners increasing assembly time.
Late design changes causing tooling rework and NPI delays.
