How it works
How residential solar energy works
Follow the path of energy from sunlight to your home.
Sunlight hits panels
Solar cells absorb photons from sunlight, releasing electrons that create a direct current (DC) of electricity.
Inverter converts DC
The solar inverter converts DC into alternating current (AC) — the standard electricity used in homes.
Power flows to your home
AC electricity powers your appliances. Surplus can charge a battery or export to the grid for credits.
Energy you can store
A home battery stores excess solar for night use or outages, maximizing your self-consumption.
