I did not know that you could generate enough power from a solar/battery setup to charge an EV. I thought they required tons of electricity (several kilowatts) to be charged. But if you can do this via solar, that would be a benefit for sure.

Oh yeah, you can get solar panels on the roof of a car port for charging. In the UK, some car parks use them for electric charging bays. What may be happening is the solar set-up takes longer to get to 80% charge than a mains set-up.

My Leaf can charge from 120V (US AC mains) at 1.2KW (takes about 28Hrs ) or Level 2 (240V) at 6.6KW (4Hrs) .
It is all about HOW long you are willing to wait.
The rate is negotiated by the EVSE (charge device), by what it can provide vs what the vehicle can accept. ANY EVSE with greater capacity will not be fully used because the vehicle can't swallow all those trons any faster )
This is why folk get mad at those with older cars hogging a 350KW chargepoint, when their car could use the 100KW unit in the next bay. It CAN't take more than it was designed for.

For what it may be worth, one local business put in a couple of solar powered EV chargers with NACS and CCS 1 connectors. With 10 400W solar panels (a 10' x 15' block) for each charger, on a bright sunny day, they will supply about 2kW average during sunlit hours. After about 4 weeks, they added a 230V AC connection to the charger to boost the charge speed to about 8 hours for a Tesla 57kWh battery (10 => 80%). After about 10 weeks, they modified the two charging stations so you needed a keycard since they had no physical lock mechanism on the charger or the parking lot and people were using them when the office was closed to charge personal EVs.

Almost no-one has a lifestyle where they need to charge an EV from empty to full every day. It just needs a bit of topping up.

That's pretty cool. Are there limitations on driving when using the gasoline engine? (max speed, less power, etc.) How far can you drive on a tank of gas, assuming the battery was discharged prior? Is driving using the gasoline engine as the only charging source OK for long term use (you probably wouldn't want to, but could you?) Or is the gasoline engine more like one of those small spare tires they're putting in many cars now - just enough to get you home for short distances at reduced speeds - but you wouldn't want to drive on it for very long.

The one friend of mine who has the Volt PHEV from 2018 has used the gasoline engine quite a bit when on longer trips. The battery is good for about 80 kilometres and then switches to the gasoline engine charging the battery so they can get about 650km before needing to fill up and the fill up is a lot faster than using a charger. At home, he has a charger in the garage and has gone 6 months without needing a fill up.

No limitations. I drive on battery and when it runs out, the engine automatically switches over.

I attached a picture of my dashboard. The number on the bottom left is battery. The number on the bottom right is gas.

Full battery charge is about 60 miles. A full tank of gas (12 gallons) is about 360 miles. The AC isn't so bad on power consumption. Heater is worse.

Yes you can. A friend had a friend that had a Volt and never plugged it in.
