Company Overview
About SPAN
SPAN is a San Francisco-based company that designs and manufactures smart electrical panels for residential and commercial applications. Founded in 2018 by ex-Tesla engineers, SPAN''s flagship product — the SPAN Panel — is an intelligent circuit breaker panel that replaces traditional electrical panels with a connected, software-controlled system. The SPAN Panel enables homeowners to monitor energy consumption by circuit in real time, set automated load priorities during grid outages, optimize solar and battery charging, and manage EV charging — all through a mobile app. Each circuit can be individually controlled via software, providing unprecedented visibility and control over home energy flows.
Business Model & Competitive Advantage
SPAN has raised $474 million in total funding. In March 2026, Eaton — one of the world''s largest electrical equipment manufacturers — invested $75 million in SPAN and established a strategic partnership to co-develop integrated home energy management solutions expected to reach market in Q2 2026. SPAN''s panels were also certified to the new UL 3141 Power Control System standard — becoming the first smart panels to receive this certification — which is now required under the 2026 National Electrical Code (NEC), creating a significant regulatory tailwind for adoption.
Competitive Landscape 2025–2026
SPAN has expanded its product line to six panel models addressing different home sizes and configurations. Its SPAN Edge product, launched in 2025, is sold directly to grid operators as a managed distributed energy resource (DER) solution, enabling utilities to orchestrate residential loads at scale for grid balancing. This dual-channel strategy — serving homeowners directly and utilities through SPAN Edge — positions SPAN as critical infrastructure for the residential energy transition.
