Hardware Test Intern

At SPAN, we are building products to enable the rapid adoption of renewable energy. As more distributed energy resources like solar and storage come onto the grid, it’s increasingly important to be able to improve the technology that sits between the grid, the home, and those distributed energy resources. SPAN’s smart panel replaces the electrical panel to become the center for connected power in the home. With SPAN, homeowners receive all the safety features of a standard panel with revolutionary insights and edge-of-grid controls through our mobile app.
