Estimate — we don't have your utility's rates for this region yet, so this uses a blended national average. Enter your own rates below to sharpen it.

Your plan credits exported solar at close to full retail, so your bill nets out whether you use solar now or later — automatic solar charging won't save much on its own. SundialEV still automates peak-avoidance charging and battery priority, and grandfathered plans change (and expire).

Even at this usage, SundialEV keeps more of your own solar in the car — free to use.
