Insulation piercing technology means faster installs with zero prep work at each tap point.
UL 9703 Listed

Every connector is fully certified — the industry's most rigorous PV connector standard.
DC Electric EBOS Support

From engineering design to kitted delivery — we support the full project lifecycle.
2-Minute Install Per Tap

Shear bolts confirm proper torque automatically — no guesswork, no callbacks, no rework.

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.
