EV Charging

Planning for an EV? Wire It Into Your Solar Thinking Now

An electric vehicle is the single biggest load most homes will ever add — a typical 12,000-mile year adds roughly 3,000–4,000 kWh of demand. When and how that charging happens determines whether an EV costs you pennies or dollars per gallon-equivalent.

The rate-window problem

Plug in at 6 PM like most people instinctively do, and you're charging through the most expensive window on a time-of-use plan. Shift charging to overnight off-peak or, better, to midday solar surplus, and the same miles cost a fraction. A charger that's integrated with your solar system can do this automatically — including a mode that charges preferentially from excess solar production.

Design ahead, install later

You don't need to buy the charger with the solar. What's worth doing at solar design time costs little: confirm panel capacity for a future 240V circuit, plan the conduit run, and size the system with the future load in mind. Then when the EV arrives, an Enphase charger joins the same platform and the same app as your panels and battery — one system, one screen, and charging that follows your sunshine instead of the peak-rate window.
