Home charging data after 1,110 miles.

I'm not sure what you mean by that. The extra power you sent to the grid gets used (with enough extra solar they don't need to fire up peaker plants), not stored so there isn't a battery involved. So, no need for anybody to charge anyone else for "storage fees". The utility doesn't have to kick in expensive peaker plants, and in exchange panel owners "get their electricity back" at night.

What I mean is it's a service to time-shift your electricity, just like a battery pack does. Except without having to spend thousand on a battery. That's a valuable service.

Now, if it's actually excess power generated when the power company needs it to avoid expensive peaker plants, it would be helpful to them, thus worth doing for free. But as I understand it, that's not the case. The duck curve pattern still requires them to keep and run peaker plants in the late afternoon and evenings when people get home from work and use up all their own generation, plus more from the grid. At the very time they need excess generation from customers, they don't get it. They just get it earlier in the day when they don't need it.

You're getting fantastic efficiency...my guess is that you're deciding not to show off too much when the red light turns green?

I have about 2,250 miles and am averaging close to 2.8 mi/kWh, but most of that is on the highway; either road-tripping or commuting. I'm not upset with that, as I knew higher speeds would do that.

To compare my stats with yours, after 2,250 miles I've spent $69 and consumed 910 kWh. That's 553 kWh at home ($0.11/kWh), 220 kWh from Electrify America (covered under my initial 250 kWh allowance), and about 137 kWh from free sources (public charging and various Level 1 plug-ins at the homes of family members).

However, the 910 kWh consumed is not the same as delivered. At home, I'm getting an average of 14% loss* between the meter and the battery (Level 2, ChargePoint 48A charging), and my EA charging appears to have about 6% loss*. so 910 kWh 'consumed' is probably closer to 800 kWh 'delivered'. This adds up, as my trip computer says I'm getting 2.8 mi/kWh so far.

* The losses are based on a comparison between the charger apps (which measure electricity consumed) vs. the FordPass app, which measures battery charge delivered. Unfortunately, the FordPass app doesn't show kWh delivered, so my calcs are probably a bit rough.

I'm just now trying to dig-in to charging data; where can I find kwH delivered during home charging?

It's a bit tricky, as the FordPass app only tells you the percent charge added, as well as the start and end SOC. It also includes a "distance added" metric, although that's pretty useless. I've had to reverse-calculate the kWh delivered by multiplying the total charge added to 88 kWh (the useable storage of my battery). This isn't perfect, but it gets you close. Also, it does not account for battery degradation, although degradation should be very minimal for most of us at this point.

I'm hoping that Ford adds the 'kWh delivered' to the charging log data sometime soon.

Just because I’m a jerk… I’m at 4,300 miles, and have yet to pay a single penny to charge. ?

24,251 miles now… still $0.00 spent on charging.

I have free charging at work - not level 2, but free - haven't needed it so far... I charge at home - but I am curious - what are the locations that provide free charging you mentioned?

I live in Washington State - and surprisingly, our state and local government are not as EV friendly as you would assume. In fact they are desperate to figure out a tax to make up for lost gas tax sales to us EV and hybrid owners... they offer weak incentives for purchasing a EV or PHEV car - and if the price exceeds $35k - well you don't get anything...

Well residents in WA also don't pay any state income taxes and you're correct. There is no free lunch when it comes to maintaining infrastructure (like roads, bridges).

Thanks, that's helpful; I discovered in the Electrify America summary sent at the completion of a session "total energy delivered" in kWh is included, so I'm trying to get a handle on home charging cost now...I had initially multiplied the hours charged times the rate (off-peak now here in central coast area of CA) of $0.20957/kWh...but that's way wrong, and not even the correct data...sheesh. Anyway, Thanks again!

You're just missing the charging rate. This will give you a rough estimate of charging cost using the included EVSE:
240V: Charging time (hr) x electric rate x 6.6.
120V: Charging time x electric rate x 1.4.

The 6.6 is because someone said the included EVSE only charges at 27.5A. Also, only charge to 90% because the last 10% charges at a slower rate. Again, this will not get you exact, but close enough.

If you think you are going to make money on your solar install, do not do it

want to save money over time, install solar (after 20 years you will have saved enough $ to pay off your investment and possibly make a few make a dollar or two, assuming the price of electricity continues to climb

NEVER, EVER lease solar panels

If you want to contribute to the greater good, install solar panels

My utility pays me 5mils/kWh, but only pays me for 80% of what I send them (which means 4mils/kWh). I have heard that some utilities pay 5¢/kWh (they sell their electricity for more than my utility company does) but that seems to be a rare exception. At that rate(5¢) I would break even on what I pay them (winter) and what they pay me (summer). The kWhs the utility buys from you or me are by far their least expensive energy source.
Some utility companies have different solar plans available now and at different times.
