Our Story

Built by Engineers,
For the Field.

Founded in
2010, NPDesign emerged when utility-scale solar was still finding its footing. We saw a
gap — installation crews spending hours stripping wire, torquing connections, and troubleshooting
combiner box failures. We built a better way.

Today we
specialize exclusively in Solar IPC trunk bus systems — technology that replaces hundreds
of field connections with a single, sealed, shear-bolt installation that takes under two minutes per
tap.

Our products
carry UL 9703 listing, cover wire ranges from 1/0 through 1000 KcMil, and have been
deployed across more than 2 GW of installed solar capacity.

How It Works

From Quote to Energization

Share Your Site Plan

Send us your array layout and single-line diagram. We'll review your EBOS requirements and recommend the right connector configuration.

Custom Engineering

We design your trunk bus layout, select IPC sizes, and specify harness tap counts to minimize connections across the array.

Kitted & Shipped

Connectors, trunk cable, harnesses, and accessories are kitted per your site zones and delivered on your construction schedule.

Install & Energize

Each IPC installs in under two minutes with a standard socket wrench. Shear bolts confirm proper torque — no guesswork, no callbacks.
