Our Mission

Lower the Cost of Residential Solar + Storage

We believe that energy independence shouldn’t be a premium product.

Today’s systems are too expensive because they weren’t designed for how homes use energy now.

Stormentum was built around a simple premise

If we want mass adoption of storage-first solar, we need to dramatically cut the cost of current systems.

The best way to do that?

Design a system that puts storage first.
