Summer solstice solar direct to car charging

[craz8]

This is the time of year where my solar panels can generate more than the 9+kw charging speed.

Now I'm fully charged for a road trip in my fusion powered Macan.

It’s a great feeling powering from the sun isn’t it!

320 miles at 90%? Wow, I wish I could see those numbers on my 4S

Love those photons!

Do Not Believe This Guess. It is entirely fictitious, made up, not even a good guess! It is showing a miles/kwh I have NEVER achieved. It’s even more fake due to charging, as the battery voltage isn’t correct

ABRP has my 100% range closer to 270 miles for the trip I’m about to take

ABRP knows which roads, what speeds, how many hills I’m about to take (several). The Porsche GOM knows nothing. (And I can’t tell it, as routing in the app is broken again)

It’s one of my favorite things, especially the SolarEdge charger that only puts the excess power into the car.

This is from late April, I find I produce a higher peak when temperatures are cooler and the days are long, May is great.

My solar edge only does solar, so my picture looks a bit sadder!

I think my best ever day was May 31 a few years ago. Sunny enough to get photons, but cool enough to not overheat the panels, and 83kwh generated

Weather in Seattle this time of year is all over though, I can get anywhere between 25kwh and 75kwh

83kwh in a day is really great on what is presumably a 10-12kw installation based on that peak. I think my record is 138kwh in a day on an installation twice that size. Then again in Utah we have more consistent sun day to day.

Indeed. In the Tesla world (I’m still part of the evil empire until my conscience salver, sorry Macan, arrives in August), the basic advice is to switch to percentage and ignore any km (mile) estimates. The percentage is no more or less accurate, but at least it’s not dependent on the journey you’re about to make, just on the charge in the battery right now.

I get the same mileage (around 3.7 miles per kw) and the same power from my solar arrays. Using 70% of the battery gave me 250 miles at highway speed on a recent trip.
